Parabon NanoLabs
Parabon NanoLabs, Inc. is a company based in Reston, Virginia, that develops nanopharmaceuticals[1] and provides DNA phenotyping services for law enforcement organizations.[2]
History[]
Parabon NanoLabs, a subsidiary of Parabon Computation, a computing software provider,[3] was founded in 2008 by Steven Armentrout, Michael Norton and Christopher Dwyer. In 2018 Armentrout was the chief executive officer and President of Parabon Computation.[1][4][5] Parabon NanoLabs has developed oncology therapeutics and synthetic vaccines using nanotechnology and DNA phenotyping.[1]
Products[]
inSēquio Design Studio[]
Together with the Edgewood Chemical Biological Center, the United States Army Research Office and the National Science Foundation as part of a project in the Federal Small Business Innovation Research program, Parabon developed a computer aided design software called inSēquio Design Studio for nanoengineering DNA constructs. This software was used to design and develop synthetic vaccines.[6]
Snapshot[]
Snapshot DNA Phenotyping Service is the name of a DNA phenotyping tool developed by Parabon NanoLabs which creates composite face imaging sketches based on DNA samples.[7] The algorithms used to make the composites are not open source, however, which has attracted criticism from members of the scientific community.[7][8] Moses Schanfield, professor of forensic sciences at George Washington University, criticized the lack of any peer review, noting that there is no publicly available performance record for the product.[5] In a 2016 article the American Civil Liberties Union recommended only using genetic phenotyping "...where the link between genes and external characteristics is based on well-proven, peer-reviewed, widely accepted science, such as is apparently now the case with hair and eye color."[9] Skin color predictions have been reported to be somewhat reliable but not predictions of the shape of the face.[10] North Carolina detectives felt Parabon's Snapshot DNA Phenotyping Service had been helpful in identifying Jose Alvarez, Jr. in 2015 as the killer of Troy and LaDonna French in 2012.[11] Privacy restrictions in 2019 on the use of GEDmatch for genetic genealogy may make DNA phenotyping more common.[12] Illumina, Inc. and Identitas AG are reported to offer similar DNA phenotyping services.[13] The United States Department of Defense provided approximately $2,000,000 in development financing for Snapshot.[10]
Keystone[]
Parabon NanoLabs was awarded a two-year contract by the United States Department of Defense to develop a software platform dubbed 'Keystone' for the forensic analysis of DNA evidence.[12]
Genetic genealogy[]
In May 2018 Parabon NanoLabs appointed genealogist CeCe Moore as head of their genetic genealogy unit[14] with three genealogists working for her.
In cooperation with American law enforcement, Parabon uploaded DNA evidence from crime scenes to GEDmatch in an attempt to identify perpetrators.[15]
In November 2018 Parabon said they were working on 200 cases, 55% had produced leads[16][17] and in May 2019 they said were solving cold cases at the rate of one a week.[18]
In May 2019, GEDmatch required people who had uploaded their DNA to its site to specifically opt in to allow law enforcement agencies to access their information. This change in privacy policy was forecast to make it much more difficult in the future for law enforcement agencies and Parabon to identify suspects and solve cold cases using genetic genealogy.[19][20]
According to an article published by Los Angeles Times in November 2019, "[CeCe] Moore said Parabon has opened about 300 DNA searches and that the lab has solved almost 100 cases — though arrests have not yet been made in several dozen of those cases."[21] In May 2020 it was reported that Parabon had participated in nearly 500 cases with 109 suspect positive identifications.[3]
In December 2019, it was announced that GEDmatch was sold to forensic, for-profit, DNA analysis company Verogen,[22] whose CEO Brett Williams vowed to make the database safer for its customers, including fighting search warrants.[23]
In a May 2020 interview with Scott Fisher of the podcast Extreme Genes, Moore revealed that in her capacity as the genetic genealogy lead, she no longer uses GEDmatch exclusively because of the decline of profiles available to law enforcement. Moore stated, "So, it would be better obviously, if we still had access to the full [GEDmatch] database, that million plus profiles, but it hasn’t stopped us. Also, we are using Family Tree DNA more and more all the time. Parabon is not able to upload directly but the agencies we work with can get the raw data from us and upload it to Family Tree DNA and then come back with that login information for us. So, we’re also helping to solve some cases with Family Tree DNA matches now. And as you know, theirs is the opt-out situation where you’re automatically opted in if you’re a US customer, unless you choose to opt out."[24] This restricted direct-access limitation may be due to the fact that FamilyTreeDNA has their own genetic genealogy consultant, Barbara Rae-Venter, who solved the Golden State Killer cold case in May 2018.[25]
On 26 May 2020, the ABC television network premiered The Genetic Detective,[26] featuring Parabon's Moore, , and The hour-long episodes feature cases that Moore's genetic genealogy team has worked on since she started with Parabon.
The following list of case results may offer an overview of Parabon's increasing activity.
Case results: To trial[]
The following cases include suspects who were identified and then arrested for the indicated offenses. All suspects are considered innocent until proven guilty in a court of law. Convictions are highlighted in green.
| Suspect(s) | Offense(s) and victim(s) | Location of offense(s) | Offense date(s) | Arrested | Outcome |
|---|---|---|---|---|---|
| Felipe Vianney Hernandez Tellez | Rape and murder of 26-year-old Adrienne "Sunny" Sudweeks | Costa Mesa, California, USA | 1997-02-22 | Fugitive | DNA and fingerprint evidence was used to match Tellez, a Mexican national living in Santa Ana at the time, to the crime scene. He was found to be living in Oaxaca, Mexico, but so far has not been extradited to stand trial for Sudweeks' murder.[27] |
| Kenneth Canzater, Jr. | Murders of 25-year-old Candra Alston and her 3-year-old daughter Malaysia Boykin | Columbia, South Carolina, USA | 2011-01-07 | 2017-03-23 | Canzater, an acquaintance of Alston who had previously been considered a suspect in the case, was linked to the crime scene via a partial palm print that was later matched to his DNA, obtained from a 2005 robbery conviction in California. He was later arrested at a motel in Corona, California, and is yet to stand trial.[28] |
| Jason David Martinez and Kadian Andre Garfield Roper | Murder of 31-year-old Michael Todd Hamilton | Coral Springs, Florida, USA | 2011-07-11 | 2017-09-19 | Both men's DNA was linked to the crime via spit and a juice bottle recovered that they had left behind. Martinez, who was living in Manhattan, New York City, and refused to provide a DNA swab, has pleaded not guilty, while Roper has implicated both himself and the former in Hamilton's murder.[29] |
| Hugo Giron-Polanco | Sexual battery and rape | Davie, Florida, USA | 2010-11-26 | 2017-12-28 | Giron-Polanco, an illegal immigrant from El Salvador, was linked to the crime via saliva police had collected from his victims' breast. He was charged with the rape, convicted and sentenced to 12 years imprisonment.[30] |
| Oscar Roberto Nunez Gonzalez | Sexual assault of a 4-year-old | Mesa, Arizona, USA | 2017-01-09 | 2018-03-14 | Gonzalez was initially arrested on a DUI charge, but a DNA sample acquired from him was later matched to the crime scene. He has admitted guilt in the case, and is now charged with one count of sexual conduct with a minor, one count of public sexual indecency and one count of second-degree burglary.[31] |
| William Earl Talbott II | Murders of Tanya Van Cuylenborg and Jay Cook | Snohomish County, Washington, USA | 1987-11-18 | 2018-05-17 | Was found guilty of two counts of aggregated first-degree murder on June 28, 2019.[32] On July 24, 2019, Talbott was sentenced to serve two consecutive life sentences without the possibility of parole. This case was the first in which CeCe Moore provided a suspect's name based on extensive genetic genealogical research. It is also the first conviction in which genetic genealogy played an integral part.[33] CeCe Moore was interviewed (audio recording) about this case and the future of genetic genealogy considering the new restrictions that have come as a result of privacy concerns.[34] |
| Gary Charles Hartman | Rape and murder of 12-year-old Michella Welch | Tacoma, Washington, USA | 1986-03-26 | 2018-06-20 | Hartman and a brother were first identified as persons of interest, but Hartman was ultimately identified using DNA from a discarded napkin.[35] In 2019 Washington state passed "Jennifer and Michella's law" named after Michella Welch and Jennifer Bastian (see below). This law allowed police more latitude in taking DNA samples from convicted sex offenders.[36] |
| Alexander Christopher Ewing | "Hammer Murders" of the Bennett family | Aurora, Colorado, USA | 1984-01-16 | 2018-07-10 | In addition to the murders of Bruce, Patricia and Melissa Bennett and the attempted murder of Vanessa Bennet, the then-unidentified killer's DNA was linked to the rape-murder of 50-year-old Patricia Smith in Lakewood six days earlier. At the time of his arrest, Ewing was serving a sentence in Nevada for the attempted murder of a couple near Henderson. In July 2021, he was found guilty of the Colorado crimes and sentenced to three consecutive life terms.[37] |
| Matthew Norman Dusseault and Tyler Grenon | Stabbing death of 81-year-old Constance Gauthier | Woonsocket, Rhode Island, USA | 2016-03-23 | 2018-07-18 | Dusseault's DNA matched the crime scene DNA and when interviewed by police, he implicated Grenon. Both men have been charged with murder and conspiracy and are being held without bail.[38] |
| Darold Wayne Bowden | Serial rapes as the "Ramsey Street Rapist" | Fayetteville, North Carolina, USA | 2006-08-23 | 2018-08-18 | August 23, 2006, is the date of the first offense of record. Multiple rapes attributed to the "Ramsey Street Rapist" occurred into 2018.[39] |
| Michael Frank Allen Henslick | Fatal stabbing and sexual assault of 22-year-old Holly Cassano | Champaign, Illinois, USA | 2009-11-02 | 2018-08-28 | Although a convicted felon, Henslick had managed to avoid DNA testing. A discarded cigarette butt was used to connect him with the Cassano murder after genetic genealogy identified him as a person of interest.[40] At the time of the murder Henslick lived a few blocks away from Cassano in a mobile home park. Police said he admitted to Cassano's murder when arrested but Henslick pleaded not guilty at his trial.[41][42] Henslick was convicted in February 2020 and sentenced the following June to life in prison without parole. Because he had continued to evade court-ordered collection of his DNA to be placed in CODIS with past convictions, a serious look at collection enforcement in felony cases has been proposed by Cassano's mother, who wants federal law to be changed so that DNA is taken immediately in the courtroom at the time of conviction.[43] |
| Marlon Michael Alexander | Serial rapes | Montgomery County, Maryland, USA | 2007 - 2011 | 2018-09-13 | Attacked at least four elderly women in Gaithersburg and Germantown, forcing two of his victims to have sex with him. Alexander would later plead guilty to first-degree rape and first-degree sexual assault at his trial, receiving a life term.[44] |
| Luke Edward Fleming | Rape and murder of 47-year-old Deborah Dalzell | Sarasota County, Florida, USA | 1999-03-29 | 2018-09-16 | Fleming lived about seven-tenths of a mile from Dalzell's home at the time of her murder.[45] In February 2020, he received two life sentences in prison.[46] |
| Jerry Lee | Fatal shooting of 28-year-old Lorrie Ann Smith | Fulton County, Georgia, USA | 1997-05-25 | 2018-10 | Lee, 61, was arrested in Alabama and brought back to Georgia. His DNA matched the DNA from blood left at the scene.[47] |
| Benjamin Lee Holmes, Jr. | Armed robbery and murder of 25-year-old student Christine Franke | Orlando, Florida, USA | 2001-10-21 | 2018-11 | After building a family tree, genetic genealogists identified Holmes and his brother as the most likely suspects. Police obtained a warrant for Holmes's DNA and found it matched the DNA left at the crime scene, eliminating his brother as a suspect.[48] |
| John Getreu | Murder by strangulation of 21-year-old Stanford University graduate Leslie Marie Perlov | Santa Clara, California, USA | 1973-02-13 | 2018-11-20 | Police said Getreu's DNA was a match with the DNA of Perlov's killer. He has a criminal record, including rape and murder done while he was a juvenile. Police are reaching out to other jurisdictions to determine if Getreu could be responsible for other unsolved rapes and murders during this time period.[49] |
| Christopher Quinn Williams | Multiple burglaries and assaults of women | Montgomery County, Texas, USA | 2015 - 2018 | 2018-12-08 | Williams' DNA has been linked to at least 4 open cases, while there could be as many as 16. He was released on $160,000 bond on the same day as his arrest.[50] |
| Robert Steven Wright | Murder of 23-year-old Renée Sweeney | Greater Sudbury, Ontario, Canada | 1998-01-27 | 2018-12-11 | Wright, a 18-year-old student at the Lockerby Composite School at the time of the murder, was arrested at his workplace at the North Bay Regional Health Centre. His trial is scheduled for October 25, 2021, following numerous delays due to the COVID-19 pandemic.[51] |
| Jerry Lynn Burns | Murder of 18-year-old Michelle Martinko | Cedar Rapids, Iowa, USA | 1979-12-19 | 2018-12-19 | Burns was "linked by DNA from blood found on Martinko's clothing and elsewhere in the car at the crime scene."[52] Burns was convicted of first degree murder on February 24, 2020.[53] |
| Russell Anthony Guerrero | Murder of 30-year-old Jack Upton | Fremont, California, USA | 1990-12-17 | 2019-01-22 | The warrant for Guerrero's arrest was made January 17, 2019, but he was living in Arizona at the time. He was arrested a few days later and is now awaiting extradition to California.[54] |
| Michael A. Soares | Murder of 66-year-old John "Jack" Fay | Warwick, Rhode Island, USA | 2013-05-17 | 2019-02-05 | Soares, a resident of Pawtucket, was arrested for Fay's murder after a DNA analysis linked his blood to a tissue left at the crime scene. He has since been arraigned at court, and has pleaded not guilty to the crime.[55] |
| Steven Harris Downs | Rape and murder of 20-year-old University of Alaska student Sophie Sergie | Fairbanks, Alaska, USA | 1993-04-26 | 2019-02-15 | Downs was working as a nurse in Maine and was extradited to Alaska upon his arrest.[56] Downs pleaded not guilty on August 14, 2019, and bail was set at $1 million.[57] |
| Thomas Lewis Garner | Murder of 25-year-old US Naval basic training graduate Pamela Cahanes | Sanford, Florida, USA | 1984-08-04 | 2019-03-13 | Garner was Cahanes' classmate at the Navy's training center and the two knew each other, according to the Seminole County sheriff's office. Garner was convicted of the murder on May 6, 2021, and sentenced to life imprisonment.[58] He has also been linked to the 1982 cold case murder of Kathy Hicks in Honolulu, Hawaii, but so far hasn't been charged with the murder.[59] |
| Theresa Rose (Josten) Bentaas | Death of her abandoned baby | Sioux Falls, South Dakota, USA | 1981-02-28 | 2019-03-08 | The full-term baby boy died due to exposure. Bentaas told authorities that she had hidden her pregnancy and gave birth while alone in her apartment, according to a court affidavit. In December 2021, Bentaas was convicted of manslaughter and sentenced to 10 years imprisonment, nine of which are suspended.[60] |
| Raymond Lawrence Vannieuwenhoven | Murder of 25-year-old David Schuldes and the sexual aggression and murder of Schuldes' fiancée, 24-year-old Ellen Matheys | Silver Cliff, Wisconsin, USA | 1976-07-09 | 2019-03-14 | Vannieuwenhoven was charged with two counts of first degree murder and pleaded not guilty. He was held on a $1 million bond.[61][62] In August 2021, he was found guilty and sentenced to two consecutive life terms in prison.[63] |
| Coley Lewis McCraney | Murder of Tracie Hawlett and sexual assault and murder of J.B. Beasley (both 17 years old) | Ozark, Alabama, USA | 1999-08-01 | 2019-03-16 | McCraney is a truck driver and preacher with no criminal record. He voluntarily gave his DNA, which was found to match the DNA from the crime scene. He is being charged with multiple counts of capital murder, including one accusing him of killing Beasley during a sexual assault.[64] |
| Todd Barket | Robbery and subsequent murder of 68-year-old Sondra Better | Delray Beach, Florida, USA | 1998-08-24 | 2019-03-27 | Barket was charged with this case after his fingerprints were acquired after he was obliged to submit them for a background check after applying for a new job. While he admitted to being present at the store, he claimed that he had touched a marble ball in the store and that's how his DNA was found. His argument was dismissed, and he was subsequently convicted and sentenced to life imprisonment.[65] |
| Terrence Miller | Rape and murder of 20-year-old Jody Loomis | Snohomish County, Washington, USA | 1972-08-23 | 2019-04-10 | This is the second arrest that Snohomish County has made as a result of their working with Parabon (the first was of William Earl Talbott II). Police were given a list of six brothers as a result of investigative genetic genealogy, but focused on Miller because he had been accused of several sex crimes as early as the 1960s and because he lived near Loomis at the time of her murder. Miller's DNA was obtained from a discarded coffee cup and matched with the DNA from semen found on Loomis hiking boot. Described as a "real predator", Miller, 77 at the time of his arrest, pleaded "not guilty".[66][67] On Monday, 9 November 2020, Miller committed suicide in his home where he was out on bail, but three hours after being found deceased, he was convicted of first-degree murder by the jury. There is the possibility that the prosecution will ask the family to pay fines in the case.[68] |
| Johnnie B. Green, Jr. | Multiple rapes, kidnappings, robberies | Fayetteville, North Carolina, USA | 2009 - 2010 | 2019-05-07 | Green is linked to multiple cold-case rapes and is currently charged with seven counts of first-degree burglary, two counts of felonious breaking and entering, 14 counts of second-degree rape, 21 counts of second-degree sex offense, five counts of first-degree kidnapping, and seven counts of common law robbery.[69][70] |
| Brian Leigh Dripps, Sr. | Rape and murder of 18-year-old Angie Dodge | Idaho Falls, Idaho, USA | 1996-06-13 | 2019-05-15 | Christopher Tapp, who was coerced into a false confession, was convicted of Dodge's rape and murder, but was exonerated on July 17, 2019. This was the first genetic genealogy case that resulted in an exoneration.[71] In May 2019, Dripps was identified as the prime suspect. When faced with the DNA evidence, Dripps admitted to her rape and murder, stating that he had intended to rape her, but her killing was "an accident." In 1996, Dripps lived across the street from Dodge and was even interviewed by the police shortly after her death. On August 23, 2019, Dripps was formally charged with rape and first-degree murder and on September 9, 2019, he pleaded not guilty to both charges.[72][73][74] In June 2021, he was sentenced to life in prison.[75] |
| Richard Eugene Knapp | Rape and murder of 26-year-old mother Audrey Hoellein Frasier | Vancouver, Washington, USA | 1994-07-17 | 2019-05-28 | Knapp, who had a criminal record, was living in Oregon at the time of his arrest. A discarded cigarette butt was used to identify him as the primary suspect.[76] |
| Michael Whyte | Murder of 20-year-old US Army Specialist Darlene Krashoc | Fort Carson, Colorado, USA | 1987-03-17 | 2019-06-13 | At the time of the crime, Whyte, a soldier also stationed at Fort Carson, had been at a club when Krashoc visited with members of her unit.[77] In June 2021, he was sentenced to life without parole.[78] |
| Ivan Keith | Serial rapes | Massachusetts, USA | 1997 - 1998 | 2019-08-02 | Keith, who had a history of sexual offences, was living in Seal Cove, Maine, at the time of his arrest. A discarded vaping pipe was used to identify him as the primary suspect. He was charged with five counts of aggravated rape, two counts of assault and battery with a dangerous weapon, two counts of kidnapping, assault with a dangerous weapon, two counts of threats to commit bodily harm, breaking and entering into a building in the night with intent to commit a felony, perjury, making false statements, and failure to register as a sex offender.[79] He pleaded guilty on all charges, and was given a combined sentence of 44 to 50 years imprisonment.[80] |
| Donald F. McQuade | Murder of 16-year-old Shelley Connolly | Anchorage, Alaska, USA | 1978 | 2019-09-04 | McQuade was arrested in Gresham, Oregon and charged with first and second-degree murder of Shelley Connolly. Connolly had been beaten, raped, dragged by a moving car and thrown over an embankment where she froze to death in the cold of the Alaskan winter. Parabon narrowed down suspects to three brothers using genetic genealogy and DNA taken from under Connolly's nails and on her body. Police found that one, Donald McQuade, had been living in Alaska at the time and obtained an exact DNA match with discarded cigarette butts.[81] |
| Robert Tyrone Hayes | First-Degree Murder of Rachel Bey, Laquetta Gunther, Julie Green, and Iwana Patton | Palm Beach and Daytona Beach, Florida, USA | 2005-12 - 2006-02 | 2019-09-15 | DNA from Bey's murder scene (Palm Beach) matched DNA form a cigarette that Hayes had discarded. Initially charged for the first-degree murder of Bey, police have since tied Hayes to three additional murders (Daytona Beach) through DNA and forensic evidence. Hayes faces the death penalty for the four first-degree murder charges. There is also the possibility of additional charges as an alleged survivor has come forward.[82][83] |
| Patrick Leon Nicholas | Rape and murder of 16-year-old Sarah Yarborough | Federal Way, Washington, USA | 1991-12-14 | 2019-10 | A convicted child molester, Nicholas was identified after investigators linked DNA left behind by used cigarette butts to the crime scene. He was arrested at a dry cleaner's in Kent, and is currently held on $5 million bail.[84] |
| Jeffrey King | Rape of a 22-year-old female | Newark, Delaware, USA | 1993-08-04 | 2019-10-03 | Parabon produced both trait predictions and leads derived from genetic genealogy for the Newark Police Department to use to focus their investigation. King, a 54-year-old man from Coatesville, Pennsylvania, was 28 at the time of the crime. This case is the result of an initiative to test previously untested sexual assault kits in Delaware.[85] |
| Giles Daniel Warrick | Rape and murder of 28-year-old Christine Mirzayan; several other rapes as the "Potomac River Rapist" | Washington, D.C., USA | 1998-08-01 | 2019-11-13 | Attacks of the "Potomac River Rapist" began May 6, 1991, and possibly ended when Mirzayan was murdered in 1998. The area covered included Washington, D.C. and Montgomery County, Maryland, USA, with these crimes being connected by common DNA at all the scenes. Warrick was arrested in South Carolina and brought to Washington, D.C., where he has been formally charged with first-degree murder of Mirzayan in D.C. and with six rapes in Montgomery County. He was not granted bail.[86] |
| Martin Isaac Tellez | Robbery and murder of 42-year-old Subir Chatterjee | Oak Ridge North, Texas, USA | 2002-02-15 | 2019-12-10 | After investigating the case for several years, detectives working on the case managed to obtain items that contained Tellez's DNA and submitted it to Parabon, whose technology confirmed that the killer's DNA was a match to his. Tellez was soon after arrested and placed on $500,000 bond, but on April 9, 2021, he removed his ankle monitor and attempted to flee to Mexico, but was reapprehended before he could do so.[87] |
| Nina Albright | Death of her newborn baby | Calgary, Alberta, Canada | 2017-12-24 | 2020-01-23 | Albright was identified with the help of DNA and additional security footage showing her and an unidentified male around the time the infant is supposed to have been born. She was arrested and is now charged with unlawful disposal of a body and failure to provide medical attention.[88] |
| William Blankenship | Rape of at least three victims (two were children) | Cincinnati, Ohio, USA | 1999 and 2001 | 2020-02-11 | Blankenship was indicted on three counts of rape, two of which were against young girls aged 10 and 15. Police in Hamilton County are actively investigating the possibility that Blankenship has committed similar crimes in the area, including in Kansas.[89] |
| James Byrd | Armed kidnapping and sexual battery on a 22-year-old woman | Tampa, Florida, USA | 1998-03-08 | 2020-02-09 | In a partnership with Florida Department of Law Enforcement (FDLE), Parabon's genetic genealogy unit provided the lead in September 2020 that led to the surveillance and procurement of a discarded cigarette butt in November. The match and arrest came in December. Byrd had been arrested for a similar attack in that same month, March in 1998, but the case was not pursued due to the lack of cooperation of the victim. Byrd's DNA has been linked to two other sexual assault cases in 1999, but he has not yet been formally charged for those crimes.[90] |
| Jonathan D. Hurst | Murder of Patricia Wilson, 85, and her son Robert Wilson, 64 | Sycamore, Illinois, USA | 2016-08 | 2020-02-24 | Since there is no known link between Hurst and the Wilson family, police have theorized that Hurst acted in a "random act of violence." Hurst is awaiting extradition from Cincinnati, Ohio to Illinois to face two counts of first-degree murder. If convicted, Hurst faces the mandatory sentence of life in prison.[91] |
| Phillip Lee Wilson | Sexual assault and murder of 20-year-old Robin Brooks | Sacramento, California, USA | 1980-04-24 | 2020-04-24 | Wilson, a small-time criminal who had convictions for assault and drug possession in California and Texas, was linked to the crime scene through some blood left at the crime scene, possibly from accidentally cutting himself while stabbing Brooks.[92] |
| Aryan Vito Smith | Fatal stabbing of 26-year-old Treeanna Nichols | Westminster, California, USA | 2018-02-05 | 2020-05 | Smith was arrested after Parabon matched DNA found at the crime scene back to him, as he had no previous criminal record. He has been charged and awaits trial for Nichols' murder.[93] |
| Joseph Matthew Gregory Jones | Murder of 52-year-old Robert Romero | Santa Fe, New Mexico, USA | 2018-07-30 | 2020-05-14 | Jones had been released four days before Romero's murder after serving 18 months of supervised probation for a fourth-degree felony (receiving stolen goods). Police can make no personal link between Jones and Romero, making this a crime of opportunity. This is the first case that Parabon solved in New Mexico.[94] DNA at the crime scene came from a pair of glasses and a flashlight and was compared to three persons of interest identified by Parabon. It was Jones's DNA that matched the DNA found at the crime scene. The execution of a search warrant for Jones's apartment revealed a handgun that may have been used to commit the crime.[95] |
| Leroy Jamal Smith | Serial rape (at least five cases) | Muskogee County, Oklahoma, USA | 1993-1995 | 2020-06-09 | Five cases have been positively linked to Smith, and Muskogee Police were asking for any other assault victims to come forward to determine if Smith was their assailant.[96] However, according to a news article on the Tulsa World website, "U.S. District Judge Ronald White on Thursday [27 August 2020] ordered Smith released from incarceration because the alleged crimes fall outside the established federal statute of limitations." Also according to the article, U.S. prosecutors have filed an emergency order to get Smith back in custody to await trial because the judgment "wrongly denied the parties a hearing to argue over the defense motion to dismiss."[97] |
| Alan Edward Dean | Sexual assault and murder of 15-year-old Melissa Lee | Snohomish County, Washington, USA | 1993-04-14 | 2020-07-29 | Dean's arrest is the third made by Snohomish County law enforcement as a result of working with Parabon (the first arrest made was that of William Earl Talbott II; the second, of Terrence Miller). The arrest of Dean was "uneventful," his DNA from a discarded cigarette matching the crime scene's DNA recovered from Lee's clothing. Dean reportedly knew Lee through a telephone "date line" and had been interviewed by police soon after her death. When Moore included Dean on her list of persons of interest, police quickly began surveillance because his name was in the case files. Dean has a previous arrest record that includes "marijuana possession, domestic violence assault, resisting arrest, failing to obey an officer and contributing to the delinquency of a minor." His bail has been set at $2 million.[98] |
| Michael Allan Carbo, Jr. | Sexual assault and murder of 52-year-old mother Nancy Daugherty | Chisholm, Minnesota, USA | 1986-07-16 | 2020-07-29 | In what Chisholm investigators believe is the first case in Minnesota in which a suspect has been identified through investigative genetic genealogy, Carbo was arrested the same day as a direct DNA sample tested positive as a match to the DNA left from the sexual assault kit and from Daughterty's fingernail clippings. Carbo went to school with Daugherty's children and was never on the suspect list during the 1986 investigation. Carbo, who still lived in Chisholm, has been charged with second-degree murder and his bail has been set at $1 million.[99][100] |
| Stephen Ray Hessler | Serial Home Invasion and Sexual Assault | Greensburg, Indiana, USA | 1982-1985 | 2020-08-17 | Hessler is a convicted felon, having served time in the 1990s for a similar crime. He faces 24 felony charges for home invasion and sexual assault of 10 victims. After Parabon provided Hessler as a person of interest as a result of investigative genetic genealogy, authorities positively identified him through a DNA sample obtained from an envelope that contained his payment for his Greensburg utility bill. He is being held in the Shelby County jail on a $20 million bond.[101] |
| Adam Antonio Spencer Durborow | Aggravated murder of 64-year-old Sherry Black | Salt Lake County, Utah, USA | 2010-11-30 | 2020-10-10 | Black was found deceased in B&W Billiards and Books, a store that she owned. The processing of the crime scene yielded DNA evidence with which Parabon created a Snapshot and performed familial research. Police collected Durborow's DNA surreptitiously and his DNA profile matched that from the crime scene. After his arrest and post-Miranda, Durborow "confessed to the homicide," but may still go to trial. He is being charged with first-degree aggravated murder and first-degree aggravated burglary, but it is currently undecided if prosecutors will seek the death penalty. Durborow is being held without bail.[102] |
| Antoinette Briley | Murder by asphyxiation of her newborn twin sons | Cook County, Illinois, USA | 2003-06-06 | 2020-12-03 | The bodies of the newborns were discovered in a garbage truck's front bucket by the driver on 6 June 2003 (but the exact date of death was not stated in the news article). Briley was identified as the mother based on a lead generated by Parabon's genetic genealogy specialists. A comparison of Briley's DNA from discarded items in Michigan identified her as the infants' mother. After her arrest, Briley admitted to her involvement in the murders of her two infant sons. She has not yet entered a plea.[103] |
| Angela Renee Siebke | Murder by asphyxiation of her newborn girl who was given the name "Baby April" at burial | Moline, Illinois, USA | 1992-04-11 | 2020-12-17 | "Baby April" was found along the shore of the Mississippi River by a man walking his dog. Many detectives worked the case, but all tips investigated did not lead to an arrest. In 2014, the police charged the DNA profile with first-degree murder. This was the first time that Rock Island County prosecutors filed a charge against a DNA profile. In 2019, Parabon was brought on board to generate leads based the results of a genetic genealogy investigation. A search warrant for Siebke's DNA was issued 1 December 2020, and based on the results, Siebke, who was living in Ohio, was arrested on 17 December 2020. She is being held in Rock Island County jail with a $1M bond.[104][105][106] |
| David Lee Blair | Murder by stabbing of 74-year-old George Washington Price | Elizabeth City, North Carolina, USA | 2016-03-24 | 2021-01-26 | The North Carolina State Bureau of Investigation (SBI) was brought in to investigate the stabbing death of Price. After all leads were dried up, they turned to Parabon in October 2020 to generate leads from DNA analysis and genetic genealogy. The Pasquotank County Sheriff's Office and SBI then focused their traditional police work on these new leads, which led to the arrest of Blair, 55, at his home in Winston-Salem. Blair has been booked without bond.[107] |

He awaits trial for the murder.[109] |
| Bruce A. Cymanski | Kidnapping and murder of 17-year-old Nancy Noga | Sayreville, New Jersey, USA | 1999-01-07 | 2021-08-31 | Cymanski was partially identified by genetic genealogy methods used by Parabon in the case, the first in the state to result in an arrest. Cymanski is currently detained and awaiting trial on kidnapping and murder charges.[110] |
| Miguel Enrique Salguero-Olivares | Killing of Faith Hedgepeth | Chapel Hill, North Carolina, USA | 2012-09-07 | 2021-09-16 | Salguero-Olivares, who was not originally considered a suspect in the case, was linked to the case after a DNA matched, submitted from a drunk driving charge, was linked to the case. He awaits trial for her murder.[111] |
| Lloyd Wendell Ailes | Sexual assault of a Miami University student | Oxford, Ohio, USA | 2006-09-01 | 2021-12-09 | Ailes' DNA was collected from an unrelated attack in Fayette County, Indiana, which was later used to trace his father and eventually single him out of as a suspect. He is awaiting trial on $775,000 bond.[112] |
Case results: Confessions and guilty pleas[]
In the following cases, the suspect arrested for the offense subsequently confessed and was sentenced without going to trial.
| Confessor | Offense(s) and victim(s) | Location of offense(s) | Offense date(s) | Arrested | Sentencing |
|---|---|---|---|---|---|
| José Silvano Alvarez Jr. | Murders of 48-year-old Douglas "Troy" and 45-year-old LaDonna French | Wentworth, North Carolina, USA | 2012-02-04 | 2015-07-25 | Alvarez was linked to the crime after his brother, John, was positively ruled out as a suspect following a DNA analysis. José and his father were later swabbed, with the subsequent samples proving that not only José Jr. was the killer, but also that José Sr. was not his biological father, the reason why the Y-STRs did not match.[113] Alvarez later pled guilty to the crimes, and was sentenced to two life terms without parole.[114] |
| Shawn J. Lawson, Jr. | Serial rapes | Athens and Lancaster, Ohio, USA | 2006–06 to 2016-06 | 2017-05-08 | Admitted to three rapes and sexual assaults committed over a decade, beginning when he was 15.[115] For these crimes, Lawson was sentenced to 40 years imprisonment.[116] |
| Justin Hansen | Attempted murder of 17-year-old Brittani Marcell | Albuquerque, New Mexico, USA | 2008-10-11 | 2017-07-05 | Hansen, an acquaintance of Marcell's who had visited her on several occasions prior to the attack, pleaded no contest to the charges and was sentenced to 18 years.

| Robert D. Washburn | Rape and murder of 13-year-old Jennifer Bastian | Tacoma, Washington, USA | 1986-08-04 | 2018-05-12 | Washburn was arrested at his home in Eureka, Illinois after DNA left at the crime was matched to him. At his trial in January 2019, he admitted to the murder and was sentenced to 27 years imprisonment.[120] In 2019 Washington state passed "Jennifer and Michella's law" named after Michella Welch (see above) and Jennifer Bastian. This law allowed police more latitude in taking DNA samples from convicted sex offenders.[36] |
| Raymond Charles Rowe | Sexual assault and murder of 25-year-old schoolteacher Christy Mirack | East Lampeter Township, Pennsylvania, USA | 1992-12-21 | 2018-06-26 | Admitted to murder and was sentenced to life without parole.[121][122] |

| Spencer Glen Monnett | Rape, burglary and assault of 79-year-old Carla Brooks | St. George, Utah, USA | 2018-04-17 | 2018-07-27 | Normally, the names of rape victims are not released, but Ms. Brooks gave permission because she wanted to raise awareness about sexual assault.[126] Monnett wrote a full confession and an apology letter. Ms. Brooks forgave him. Monnett was charged with rape and burglary and sentenced to a five-year-to-life term.[127] |
| Unidentified 17-year-old Juvenile Offender | Aggravated assault of 71-year-old organist Margaret Orlando | Salt Lake City, Utah, USA | 2018-11-17 | 2019-04-24 (announced) | This was the first use of GEDMatch for a crime other than rape or murder and was CeCe Moore's first active case. This case also brought on the change in GEDMatch's Terms of Service, expanding the crimes for which the database could be used by law enforcement. GEDMatch removed all profiles from law enforcement's access and introduced the requirement for members to "opt-in" to allow law enforcement's access.[128] The juvenile offender confessed and was sent to youth lockup. Ms. Orlando forgave him at his sentencing for aggravated assault and aggravated burglary.[127] |
| Marquise D. Dozier | Multiple rapes | Allen County, Indiana, USA | 2015 - 2017 | 2019-03 | Dozier pleaded guilty to three counts of rape as part of a plea agreement.

Charges against Frampton included first-degree murder, second-degree murder, and armed robbery.[131] In September 2019, Frampton pleaded guilty to first-degree murder and was sentenced to life in prison, with the judge suspending all but 55 years.[132] |
| Zachary Aaron Bunney | Murder of 47-year-old Scott Martinez | La Mesa, California, USA | 2006-06-17 | 2019-01-10 | Martinez was stabbed several times with a sword in his home. The suspect left two blood stains, most likely the result of cutting himself while killing Martinez. Police traveled to Oregon to obtain an oral swab of Bunney's DNA, which proved to be a match to the crime-scene DNA.[133] He pleaded guilty and was sentenced to 12 years in prison.[134] |
| Jesse Bjerke | Rape of a 24-year-old female lifeguard at gunpoint | Alexandria, Virginia, USA | 2016-09 | 2019-02 | On 17 October 2019, Bjerke pleaded guilty to all six charges against him. In return for his guilty plea, he would not be sentenced to a life term. He was identified through genetic genealogy and then confirmed as a match after his DNA was obtained from a discarded drinking straw. On 2 October 2020, Bjerke was sentenced to 65 years for this and a second rape that occurred in Fairfax County in August 2014.[135][136] |
| Dennis Lee Bowman | Rape and murder of 25-year-old Kathleen Doyle | Norfolk, Virginia, USA | 1980-09-11 | 2019-11 | At the time of the crime, Bowman was a Navy Reserve officer serving aboard the USS Piedmont. After being contacted by authorities in Norfolk, Parabon developed a snapshot and later a list of 30 potential suspect, amongst whom was Bowman. His DNA later proved to be a match to the case, he was arrested and later pleaded guilty to Doyle's murder, receiving two life sentences. He has also pleaded guilty to the 1989 murder of his stepdaughter Aundria Bowman in Michigan, for which he is still awaiting sentencing.[137] |
| James Curtis Clanton, formerly known as Curtis Allen White | Murder of 21-year-old Helene Pruszynski | Douglas County, Colorado, USA | 1980-01-16 | 2019-12 | At the time of Pruszynski's murder, Clanton was on parole for rape in Arkansas after serving about four years. His DNA was not in CODIS, however. Charges include felony murder predicated on an underlying crime of robbery and felony murder predicated on an underlying crime of sexual assault. Clanton was positively identified after genetic genealogy led police to him. They put him under surveillance and were successful in obtaining a beer mug that Clanton had used at a bar. Police are investigating if Clanton was responsible for other sexual assaults in the area at the time of Pruszynski's murder.[138][139] In February 2020, Clanton pleaded guilty to first degree murder and was sentenced to life imprisonment with the possibility of parole.[140][141] |

| Daniel Leonard Wells | Sexual battery and murder of 23-year-old Tonya Ethridge McKinley | Pensacola, Florida, USA | 1985-01-01 | 2020-04-01 | Daniel Leonard Wells, 57, was facing charges of first-degree murder and first-degree sexual battery. Several items of evidence led investigators to determine that they were looking for only one suspect, whom Parabon and investigators ultimately identified as Wells. Police obtained one of Wells's discarded cigarettes to test his DNA for a match. "According to the arrest report, there is a less than 1 in 700 billion chance that the DNA from the crime scene is a match to anyone other than Wells." He was arrested on March 18, 2020, and was awaiting his first hearing that was scheduled for April 8, 2020.[178] While in his jail cell, Wells hung himself, not giving McKinley's family the answers they had hoped for. McKinley's son stated, "It’s frustrating for our family on a lot of levels because we waited so long to get justice. Now, it seems like we just have a lot more unanswered questions."[179] |
| Vernon Parker | Murder of 17-year-old Mary London | Sacramento, California, USA | 1981-01-14 | 1982-08-23 | The Sacramento Police Department said Parker was murdered in 1982, just over a year after London was slain.[180] |
| Daniel Alan Anderson | Murder and dismemberment of 15-year-old John A. Muncy | Columbus, Ohio, USA | 1983-10-15 | 2013-08-29 | Although Muncy's remains were found on the western edge of Delaware County, police believed the teenager had been slain in Columbus and then dumped. Anderson and two of his brothers were first identified as persons of interest. Working with the Ohio Bureau of Criminal Identification and Investigation, detectives ultimately positively identified the deceased Anderson as the murderer. Anderson had a violent criminal past involving boys, according to Sheriff Russell Martin.[181] |
| Steve Allen Branch | Rape and murder of 17-year-old Jessica Baggen | Sitka, Alaska, USA | 1996-05-04 | 2020-08-03 | Branch was living in Arkansas at the time he was identified as a primary suspect through investigative genetic genealogy. Arkansas police attempted to get a voluntary DNA sample from him, but he refused, denying any involvement with the crime. About 30 minutes after the interview, Branch committed suicide. After obtaining a warrant, police tested a DNA sample from Branch's autopsy and it proved to be a match with the DNA from the crime scene.[182][183] |
| Jimmie Dean Duncan | Sexual assault and murder of 19-year-old Deborah Tomlinson | Grand Junction, Colorado, USA | 1975-12-27 | 1987-12-24 | Duncan, who died in 1987, was identified by the Colorado Bureau of Investigation by comparing the crime scene DNA with a known close, living relative. At the time of the murder, he was 26 years old. Chief of Police Doug Shoemaker said in a press release, “Cold cases are never truly closed. Solving these types of cases is very important to our detectives and our agency, and while not every case is solved, we are proud of the hard work put forth by those who helped provide answers to the victim’s family and our community in as many cases as is possible.”[184] |
| Ricky Jay Severt | Sexual assault and beating death of 23-year-old mother of two Jennifer Watkins | Colorado Springs, Colorado, USA | 1999-11-05 | 2001-11-02 | Watkins's husband called in a missing person report after she failed to pick up her two children and return home after her shift in the kitchen at Memorial Hospital in Colorado Springs. Her body was found days later in a remote stairwell at the hospital where she worked. Even though Severt had access to that stairwell as a member of the maintenance staff, he was not considered a suspect after his interview early in the investigation. Severt died as a result of an automobile accident and prosecutors have "closed the case."[185] |
| James Alan Neal | Sexual assault and murder of 11-year-old schoolgirl Linda O'Keefe | Newport Beach, California, USA | 1973-07-06 | 2020-07-22 | Neal was identified as a result of genetic genealogical research using FamilyTreeDNA. Detectives who worked the homicide originally carefully preserved DNA evidence that made Neal's identification possible over 45 years later.[186] Neal, who also was known as James Albert Layton, Jr., was arrested on 22 February 2019, and was placed in a maximum-security jail to await trial. On 25 May 2020, Neal became ill and was transported to a local hospital, where he subsequently died on 22 July 2020.[187] |
| Jaime "James" Zamora | Kidnapping and sexual assault of a 7-year-old girl | Greeley, Colorado, USA | 2001-09-18 | 2014 | Zamora was 26 at the time of the crime. In 2019, Parabon produced a Snapshot image of him and also conducted a genetic genealogy investigation. Positive identification was made when the DNA evidence was compared to evidence from Zamora's autopsy. Greeley Police detective Robert Cash has asked to be contacted at (970) 350-9601 by anyone who has more information about Zamora, who was estranged from his family, worked in a Greeley sandwich shop that is now closed, and a loner.[188] |
| Ronald Albert Shroy | Murder of 17-year-old Eric Goldstrand and sexual assault and murder of his 16-year-old girlfriend Lliana Adank | Eugene, Oregon, USA | 1977-06-09 | 2021-02-24 | DNA evidence obtained at the crime scene and analyzed by Parabon led to the authorities tracking down the Shroy brothers, who were living in Mesa, Arizona. Before they could question either, however, the pair got into a fight, resulting in the younger one being harmed while Ronald committed suicide on the spot.[189] |
| David Edward Doran | Serial rapes as the "Myers Park Rapist" | Charlotte, North Carolina, USA | 1990–06 to 1999–01 | 2008-06-24 | From 1990 to 1999, an unidentified rapist broke into various homes in the neighborhood of Myers Park and sexually assaulting at least 15 victims, most of which were underage. Doran was linked to the rapes via his DNA in December 2021, but could not be arrested, as he has been deceased since 2008.[190] |
| Ray Mason Whitson, Jr. | Murder of 19-year-old Kirk Wiseman and sexual assault and murder of his 17-year-old girlfriend Cynthia Frayer | Klamath Falls, Oregon, USA | 1978-09-24 | 1996-04-15 | At the time of the crime, Whitson lived and worked as a lumberman, and is believed to have picked up the couple while they were hitchhiking. Parabon used DNA recovered from the crime scene to tentatively link the victims with Whitson's family members, eventually leading to him. However, he could not be arrested, as it was discovered that he died in Texas in 1996 from an undisclosed illness.[191] |
| John Charles Bolsinger | Serial murders of Gladys Hensley, Janice Dickinson and Geraldine Toohey | Eugene, Oregon, USA | 1986-06-05 to 1988-02-28 | 1988-03-23 | The three killings were forensically linked via DNA in 2016, more than three decades after they were initially committed. In February 2022, Parabon identified the suspected perpetrator as Bolsinger, a paroled convict with a record for murder in Salt Lake City, Utah dating back to 1980. However, he could not be arrested as he killed himself in 1988, a little over a month after his final known murder. Police are still interested in learning more about Bolsinger's activities while in Lane County. If you have information about him, police ask you to contact Detective Jennifer Curry at 541-682-5166 or jcurry@eugene-or.gov.[192] |
| James Paul Forte | Sexual assault and murder of 9-year-old Marise Chiverella | Hazleton, Pennsylvania, USA | 1964-03-18 | 1980-05-16 | While a DNA profile was developed of the suspect in 2007, it was not uploaded to Parabon NanoLabs until 2019. A familial match eventually led to Forte, who had convictions for aggravated assault and reckless endangerment, but had died of a suspected heart attack in 1980. At present, it is one of the oldest cold cases to be solved via genetic genealogy.[193] |
Case results: Identification of John and Jane Does[]
Unidentified remains of deceased individuals are given the names Jane Doe for females and John Doe for males. In cases where homicide is suspected, the identification of the remains is the first step in finding the deceased's killer. Not all Does are victims of homicide, however.
| Identified | Location of remains | Deceased | Discovered | Identified | Details |
|---|---|---|---|---|---|
| Shaquana Marie Caldwell | Glen Burnie, Maryland, USA | 2017-05 (?) | 2017-06-14 | 2017-11-13 | Caldwell was reported missing by her family members after she had failed to appear at her workplace in Baltimore. After her decomposed remains were discovered, authorities contacted Parabon for assistance, who managed to identify her via dental records. Her boyfriend, convicted murderer Taras Caldwell (no relation), was arrested and charged in her murder.[194] |
| Hassan A. Alkebu-Lan | Chesterfield County, Virginia, USA | 2016 (?) | 2016-03-13 | 2019-03 | The body of AlKebu-Lan, 39, of Richmond, Virginia, was found by a fisherman near the James River. Police do not suspect this was a crime scene as there were no signs of foul play. He was identified in March 2019.[195] |
| Donna Marie Prudhomme and Audrey Lee Cook | League City, Texas, USA | 1991-07 (Prudhomme) 1985-12 (Cook) |
1991-09-09 (Prudhomme) 1986-02-02 (Cook) |
2019-04 | Known individually as "Janet Doe" and "Jane Doe", Prudhomme and Cook's bodies were located at different dates in the Killing Fields, an area bordering Texas's Calder Oil Field, thought to be a dumping ground for the victims of several serial killers from the 1970s until the early 2000s. Each was identified via DNA matches to relatives, but their killer(s) have not been located thus far.[196] |
| "Julie Valentine" | Greenville, South Carolina, USA | 1990-02-13 | 1990-02-13 | 2019-04-04 | The body of an infant girl inside a box thrown in a trash-littered field behind a local shopping center. After her identification, the infant's mother, Brook Graham, was charged with her death and that of another child committed a year prior.[197] |
| Roger Hearne Kelso | Anne Arundel County, Maryland, USA | 1963 (?) | 1985 | 2019-06 | It was determined that Kelso was a homicide victim after he was found inside a trash can during building excavation in 1985. The young man was last seen in 1962 and coins found near his remains date no later than 1963. The perpetrator or perpetrators have not yet been identified. Police have set up a tip line and a $10,000 reward is still being offered for more information about Kelso's murder. Long before Kelso's identification through genetic genealogy, Parabon featured Kelso on their website to demonstrate the combination of DNA phenotyping and facial reconstruction techniques to put a face on unidentified remains.[198][199] |
| Tina Len Cabanaw | Angola, Indiana, USA | Before 1999 | 1999-09-06 | 2019-07 | Cabanaw, a Detroit resident with a history of leaving for days on end without notice, was found in a field in rural with a bra wrapped around her neck, indicating that she had been strangled. A positive match was made through her daughter, who now lives in Colorado. The investigation into Cabanaw's murder is ongoing.[200] |
| Sandra Renee Morden | Vancouver, Washington, USA | Between spring 1977 and fall 1978 | 1980-02 | 2019-10-29 | Sandra's bones were discovered by a father and son who were panning for gold in the Fly Creek Area near Amboy, Washington. She was given the name "Fly Creek Jane Doe." Parabon created both a Snapshot Phenotype image and conducted genetic genealogy research to find her family. Sandra's identity was confirmed using a reference DNA sample for the family given by a cousin, who knew the family story about a cousin who had gone missing in the 1970s. Sandra was born in 1962 and would have been about 15 or 16 years old when she died. Because Sandra's skeletal remains show trauma indicative of "homicidal violence," her case file remains open to find her killer: contact Detective Schultz at (360) 397-2036 if you have more information about Sandra's family.[201] |
| Perrean Tamar Flennaugh Gray | Sacramento, California, USA | 2001-01 | 2001-01-29 | 2019-11-29 | Gray's charred body was found by firefigters in a burning dumpster, after she had been reported missing earlier that month by family members in San Francisco. Initial composite images depicted her as white, but using DNA phenotyping, Parabon determined that she was of African descent. Due to the circumstances surrounding her death, authorities are seeking information regarding Gray's killer, and anyone with information regarding Perrean Gray's disappearance and death should call the Sacramento Police Department's dispatch center at 916-264-5471 or Sacramento Valley Crime Stoppers at 916-443-4357.[202] |
| William Arthur Fiegener | Parker County, Texas, USA | Fall of 1984 | 1985-10 | 2019-12-23 | William's remains were buried in a shallow grave discovered by a father and son who were searching for a building site for a new home. CeCe Moore stated that this case was one of the longest she had worked on to-date. Officials have not made public the cause of death, but it was determined to be a homicide.[203] In February 2020, police identified Forrest Ethington, Feigener's partner in crime, as the most likely murderer. Ethington had confessed to killing "Billy" to another associate after Fiegener was arrested for committing a smash and grab robbery using Ethington's daughter's car. The suspected motive was that Ethington feared that Fiegener would implicate him. Ethington committed additional crimes after Feigener's death, one for which he was sentenced to prison in 2010. He died in prison in October 2019 at the age of 81. Police announced that they would clear the case "by exception and the reason for the exceptionally cleared status will be death of the offender."[204] |
| Kelly Gene Perry | Livermore, California, USA | 1996 | 1997-05-27 | 2020-03 | Perry disappeared under suspicious circumstances after leaving his fiancée in Hayward, with his remains found by a farmer in a rural area. Originally thought to possibly be from Central America or Mexico, DNA testing proved that the decedent was from Europe and was eventually identified as Perry. Investigation into his murder is ongoing.[205] |
| Christy Lynn Floyd | Chester, Virginia, USA | 1986-06 | 1986-08-07 | 2020-08 | Floyd had gone missing from her home in Richmond, and her dismembered remains were later found in a dumpster. An autopsy determined that she could possibly have been preserved in a sealed container to prevent decomposition, but her identity was not ascertained until decades later. As of 2021, authorities are seeking information to resolve her murder, and anyone with information regarding the case is urged to call the Chesterfield County Unsolved/Major Investigations Group at (804) 717-6024.[206] |
| Wanda Ann Herr | Government Camp, Oregon, USA | 1976 | 1986-08-02 | 2020-10-22 | Wanda's partial skull, a tooth, and several bone fragments were discovered by two Forest Service workers. Multiple attempts to identify the remains were made in the several decades following the discovery, but it was in January 2019 that the investigation gained renewed momentum. That is when the "Oregon State Medical Examiner's Office received National Institute of Justice (NIJ) grant funds to perform forensic genetic genealogy and DNA phenotyping on 100 unidentified human skeletal remains cases." Wanda was born in 1957, making her approximately 19 years old at the time of her death, which is estimated to be shortly after she was last known to be alive in June 1976. Now, the Clackamas County Sheriff's Office is asking if anyone who can provide additional information about Wanda to contact them through their tip line (503-723-4949) to help move the case (CCSO Case # 86–025724) forward.[207] |
| Freeman Asher Jr. | Multnomah Falls, Oregon, USA | 1977 | 1979-09-14 | 2021-01 | The last time Asher's family had seen him, he was signing a song that was released in 1977, so this is the year that it is believed that Asher died, at around 34 years of age. Because there were no physical signs of the cause of death on the remains, such as by a violent act, the case has been closed and the remains returned to the family for burial. Asher was formerly known as "John Doe 79-1862."[208] |
| Marie Petry Heiser | Townsend, Delaware, USA | 1977 | 1977-06-27 | 2021-03 | Heiser, a part-time employee at the Ashbourne Country Club in Cheltenham, Pennsylvania, disappeared sometime in 1977. Her body was found in a drainage ditch along a rural road, but was not positively identified as Heiser's until decades later. While her exact cause of death has not been determined, authorities have said that it is homicidal in nature, with the prime suspects being her husband and serial killer Henry Lee Lucas.[209] |
| Vincent Marion Trapp | Wellington, Nevada, USA | 1991 | 1992-03-12 | 2021-05-26 | Known as "Sand Canyon John Doe", Trapp's skeleton was found on at an apparent campsite and was likely murdered. Police are currently investigating two potential suspects in his killing. If you know anything about the murder of Trapp, contact Detective Lt. Jerry Pattison of the Major Crimes Division of the Lyon County Sheriff's Office at (775) 577–5206, or Investigator Matthew When of the Nevada Division of Investigation at (775) 684–7412.
If you wish to provide information anonymously, call or text Secret Witness at (775) 322–4900.[210] |
| Steven Alexander Crawford | Ashland, Oregon, USA | 1962–1963 | 1963-07-11 | 2021-06-25 | The body of the approximately 3-year-old toddler was found in a reservoir, but cause of death was undetermined. After his identification in June 2021, it was announced that Crawford's mother, who is now deceased, was last seen with the boy.[211] |
| Leopoldo Torres Melendez | Lower Lake, California, USA | 1970s | 1976-11-28 | 2021-10 | The decedent's remains were found in a rural, heavily wooded area, and was identified as Melendez through a DNA match to his biological sister. Melendez, who was born in Puerto Rico but lived in the San Francisco area, disappeared under unclear circumstances and was later beaten to death with a blunt instrument.[212] |
| Winston Arthur Maxey III | Coos Bay, Oregon, USA | 1971 | 1971-07-29 | 2021-10 | Maxey, a 15-year-old runaway from Boise, Idaho, was identified through his daughter, who was adopted at an early age and never met her father. His cause of death is unclear.[213] |
| Robin Pelkey | Palmer, Alaska, USA | 1983 | 1984-04-25 | 2021-10 | Nicknamed "Horseshoe Harriet", it was determined that she had been shot to death by serial killer Robert Hansen, who did not know her true identity. In October 2021, using genetic genealogy, she was identified as 19-year-old Robin Pelkey of Anchorage.[214] |
| Carolyn Dunn Moudy | Davie, Florida, USA | 1974-07 | 1975-12-23 | 2021-12 | The decedent's body was recovered from a canal, where she had been dumped by after supposedly being murdered by an unknown assailant. The case was taken up by Parabon and LSU FACES, who positively identified her 21-year-old Carolyn Moudy of Indianola, Mississippi. The investigation into her murder is ongoing.[215] |
| Haley Mae Coblentz | Van Duzer State Park, Oregon, USA | 2020 | 2020-12-10 | 2021-12 | The remains of a young girl were found stuffed inside a duffel bag at the Van Duzer State Park. She remained unidentified until a year later, when she was identified as 9-year-old Haley Coblentz. Immediately after her identification, Coblentz's mother Shawna Browning and her girlfriend, Lauren Harrison, were arrested in her murder.[216] |
