# Parabon NanoLabs

Parabon NanoLabs, Inc. is an American company based in Reston, Virginia, that develops nanopharmaceuticals and provides DNA phenotyping services for law enforcement organizations.

## History

Parabon NanoLabs, a subsidiary of Parabon Computation, a computing software provider, 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. Parabon NanoLabs has developed oncology therapeutics and synthetic vaccines using nanotechnology and DNA phenotyping.

## 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.

### 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. The algorithms used to make the composites are not open source, however, which has attracted criticism from members of the scientific community. 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. 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." Skin color predictions have been reported to be somewhat reliable but not predictions of the shape of the face. 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. Privacy restrictions in 2019 on the use of GEDmatch for genetic genealogy may make DNA phenotyping more common. Illumina, Inc. and Identitas AG are reported to offer similar DNA phenotyping services. The United States Department of Defense provided approximately $2,000,000 in development financing for Snapshot.

### 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.

### Genetic genealogy

In May 2018 Parabon NanoLabs appointed genealogist CeCe Moore as head of their genetic genealogy unit 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.
In November 2018 Parabon said they were working on 200 cases, 55% had produced leads and in May 2019 they said were solving cold cases at the rate of one a week.
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.
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." In May 2020 it was reported that Parabon had participated in nearly 500 cases with 109 suspect positive identifications.
In December 2019, it was announced that GEDmatch was sold to forensic, for-profit, DNA analysis company Verogen, whose CEO Brett Williams vowed to make the database safer for its customers, including fighting search warrants.
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." 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.
On 26 May 2020, the ABC television network premiered The Genetic Detective, featuring Parabon's Moore, Steven Armentrout, Ph.D., and Ellen McRae Greytak, Ph.D. 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. |
| 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 extradited to South Carolina to face trial. In 2020, he was convicted on two counts of voluntary manslaughter and sentenced to 20 years imprisonment. |
| 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. In June 2023, Martinez was convicted of the murder and sentenced to life imprisonment. |
| 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. |
| 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. |
| 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. 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. 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. |
| 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. 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. In 2022, he was sentenced to 26 years imprisonment. |
| 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. |
| Matthew Norman Dusseault | 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 Tyler Grenon. Both men were charged with murder and conspiracy, however the charges against Grenon have since been dropped and Dusseault is being held without bail. Convicted in January 2025. |
| 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. 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. 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. |
| 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.

| 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. In February 2020, he received two life sentences in prison. |
| 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. He was convicted of the murder and sentenced to life imprisonment without parole in March 2023. |
| 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. In August 2022, Williams was convicted and sentenced to life in prison. |
| 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.

| 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. |
| 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". 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. |
| 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. 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. In June 2021, he was sentenced to life in prison. |

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. In April 2024, McQuade was sentenced to 50 years imprisonment. |
| Robert Tyrone Hayes | Serial murders of Laquetta Gunther, Julie Green, Iwana Patton and Rachel Bey | Palm Beach and Daytona Beach, Florida, USA | 2005-12-26 to 2016-03-07 | 2019-09-15 | DNA from Bey's murder scene (Palm Beach) matched DNA form a cigarette that Hayes had discarded, which was later matched to the other murders. He was found guilty and sentenced to three life terms without parole for the murders of Gunther, Green and Patton, but is yet to stand trial for the murder of Bey. |
| 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 was held on $5 million bail. In May 2023, Nicholas was convicted and sentenced to 45 years imprisonment. |
| 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 was extradited from Cincinnati, Ohio, to Illinois to face two counts of first-degree murder. Hurst was convicted in January 2025. |
| 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. In April 2022, he was convicted and sentenced to life without parole. |
| 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. 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. In February 2023, he was convicted of felony murder. |
| Alan Edward Dean | Sexual assault and murder of 15-year-old Melissa Lee | Bothell, 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." He was found guilty in March 2024 and sentenced to 26.5 years imprisonment. |
| 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. In October 2022, he was convicted on two counts of first-degree murder and sentenced to life imprisonment with a chance of parole after serving 17 years. |
| 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 was convicted on 19 felony charges and sentenced to 650 years imprisonment in March 2022. |
| 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. |
| Clayton Bernard Foreman | Rape and murder of Mary Catherine Edwards | Beaumont, Texas, USA | 1995-01-15 | 2021-04-26 | The Beaumont Police Department and the Texas Rangers led the investigation, with the assistance of the Franklin County (Ohio) Sheriff's Office, the FBI and the DPS Criminal Laboratory. The Jefferson County Sheriff's Office aided the investigation. It has been confirmed that Edwards and Foreman knew each other long before the murder and that Edwards was once a bridesmaid at Foreman's wedding. Foreman had a previous sexual assault conviction in 1981 He was convicted of the murder in 2024 and was sentenced to life imprisonment with a chance of parole after 30 years. |
| Gustav Ryburn | Sexual assault of a Vincennes woman in her residence | Vincennes, Indiana, USA | 2008-11-21 | 2021-04-27 | At the time of the crime, Ryburn was worked at a bar in the city, and had no connection to the victim. Until his arrest, it was the city's only unsolved violent crime. In September 2022, he was convicted and sentenced to 80 years imprisonment. |
| Robert Arthur Plympton | Rape and murder of 19-year-old Barbara Tucker | Gresham, Oregon, USA | 1980-01-15 | 2021-06-09 | Plympton was arrested during a routine traffic stop, and his DNA was later used to link him to the crime, which was one of the city's oldest cold cases. He was convicted of the murder in March 2024 and faces a life sentence. |
| 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. Found guilty in October 2024. |
| 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. |
| William Clark | Sexual assault of a 14-year-old girl | Fairfax, Virginia, USA | 1987-03-06 | 2022-04-20 | At the time of the crime, Clark, pretending to be radio host Don Geronimo, phoned the victim and claimed that she had won $1,000 and a trip to Hawaii, which she could collect at a local radio station. When the victim arrived, she was abducted and taken to a dirt road, where she was raped. While DNA was collected in 2005, it was not until the police contacted Parabon that a profile of the perpetrator was developed, leading to Clark's identification and subsequent arrest. He is facing several counts of rape, abduction with intent to defile and attempted forcible sodomy. |

| Curtis Edward Blair, Sr. | Brutal stabbing murder of 15-year-old Reesa Trexler | Salisbury, North Carolina, USA | 1985-06-15 | 2004-08-06 | Salisbury Police held a press conference on Tuesday, December 3, 2019, to announce that they have reached a conclusion on the brutal stabbing murder of teen Reesa Trexler. DNA collected from semen left in Trexler's body was analyzed by Parabon to produce both an ethnicity profile as well as a family tree through genetic genealogy. After the suspect was identified, Curtis's body was exhumed to obtain his DNA in order to confirm the identification. Curtis, who was in his 40s at the time of the crime has a criminal record. They declared the case "solved and now closed" and fully exonerated her sister, Jodi Trexler Laird, who had long been suspected of her sister's murder. |
| James Francis McNichols | Rape and murder of 11-year-old Julie Fuller | Fort Worth, Texas, USA | 1983-06-27 | 2004-01-28 | In early December 2019, Fort Worth police announced that they had positively identified McNichols as the man who raped and murdered Julie Fuller as she was taking out the trash at the Kensington Motor Lodge and Apartments. This was the first case in which Fort Worth police used genetic genealogy and they are reviewing other cases in which DNA evidence could be analyzed in the same manner to identify the offenders. |
| Clifton Hudspeth | Murder of 16-year-old cousins Jeffrey Flores Atup and Mary Jane Malatag | Milpitas, California, USA | 1982-12-20 | 1999-10-07 | Hudspeth had a history of criminal activity, including bank robberies, sexual assaults and at least one attempted homicide.

Police are asking for help from the public to determine if Hudspeth is responsible for other offenses in Arkansas and San Diego, California, places where he had been known to live. |
| Bruce Everitt Lindahl | Sexual assault and murder of 16-year-old Pamela Maurer | DuPage County, Illinois, USA | 1976-01-12 | 1981-04-04 | It was announced during a press conference on January 13, 2020, that the late Bruce Lindahl was identified as the murderer of high school student Pamela Maurer. Lindahl died from "apparent accidental, self-inflicted injuries he sustained in the 1981 stabbing murder of Charles Huber, 18, of Naperville." His body was exhumed to make the positive identification. Investigators have "evidence possibly connecting Lindahl to crimes against other women between approximately 1974 and the time of his death in April of 1981." |
| Wesley Roy Backman | Murder of 25-year-old Tangie Sims | Aurora, Colorado, USA | 1996-10-24 | 2008-11-17 | "Aurora police on Wednesday announced that Wesley Backman, a truck driver who died in 2008 at the age of 53, was identified as the suspect through advancements in DNA testing, genealogical research, a relatively new technique for investigators that uses ancestry databases to identify relatives of suspected killers." |
| Lorinzo Novoa Williams | Three counts of rape | Cobb County, Georgia, USA | 1999–06 to 1999–10 | 2019-12-11 | Williams was identified using genetic genealogy. He was first approached and interviewed by police who traveled to Arkansas where he lived. The suspect denied committing the sexual assaults, but just days after the interview, the suspect went missing and was then found dead (unspecified cause of death). Subsequent DNA testing on the suspect's remains confirmed matches to the DNA evidence from the three rapes. Williams had a criminal record, including peeping tom, indecent exposure and burglary. |
| Hans Alejandro Huitz | Murder of 57-year-old storeowner James Essel | Comus, Maryland, USA | 1992-03-22 | 2020-02-12 | Huitz was identified as the prime suspect after blood samples left by the perpetrator at the crime scene were matched to him. On February 12, 2020, a U.S. Marshals task force attempted to take him into custody at his home in Virginia Beach, Virginia, but Huitz drew a handgun, alternating between threatening to shoot himself or one of the marshals. Eventually, Huitz was shot and killed on the spot, in what was later declared by a judge as a justifiable homicide. |
| Robert Dale Edwards | Murder of 57-year-old Naomi Sanders | Vallejo, California, USA | 1973-02-27 | 1993-12-31 | Edwards' father was a co-worker of Sanders. At the time of the crime, Edwards was 21 years old. Parabon identified two possible suspects: one living and one deceased. The living lead was eliminated. Because the second lead, Edwards, had been deceased and cremated, investigators made a positive identification through his son's DNA. |
| Clayton Carl Giese | Rape and stabbing death of 12-year-old Marsi Belecz | Spokane, Washington, USA | 1985-08-04 | 1989-01-29 | Giese's family assisted the investigation by authorizing the exhumation of his body to positively identify him. He was 21 years old at the time of the murder of Belecz and died in a car accident about four years after. Belecz's sister "found comfort in knowing Giese can no longer hurt [anyone], but sent her regards to Giese's family, because she said she knows what it is like to lose someone so young." |
| 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. 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." |
| 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. |
| 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. |
| 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. |
| 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." |
| 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." |
| 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 Family TreeDNA. Detectives who worked the homicide originally carefully preserved DNA evidence that made Neal's identification possible over 45 years later. 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. Genetic genealogy was not conducted by Parabon. |
| Thomas Oscar Freeman | Sexual assault and murder of 32-year-old Lee Rotatori | Council Bluffs, Iowa, USA | 1982-06-24 | 1982-07 | The perpetrator's identification was further complicated by the fact that Freeman was adopted. Working as a truck driver at the time of the murder, Freeman's body was found in Cobden, Illinois, four months later, having died in an apparent homicide. His killer remains unidentified, although Rotatori's now-deceased husband has been named as a person of interest. |
| Mark Alan Long | Attempted murder of Jeff Garner | Watauga, Texas, USA | 2003-03-03 | 2022-04 | On the date of the crime, Garner, a policeman, was informed of an ongoing bank robbery and went after the suspect, who opened fire and hit Garner in the leg before speeding away. Analysis from evidence later linked the unknown suspect to a number of bank robberies committed from 1998 to 2003, but were unable to capture the perpetrator. With the aid of Parabon, Identifiers International and GEDMatch, authorities used DNA to link the crime to Long, who now lived in Oklahoma City, Oklahoma. However, he was found dead in an apparent suicide, with police suspecting that he opted to take his life after learning that the authorities were after him. |
| Cecil "Howie" Trent | Sexual assault and murder of 37-year-old Lisa Fracassi | Waikiki, Hawaii, USA | 1994-10-31 | 2013-08-19 | While the perpetrator's DNA was collected in the initial investigation, authorities were unable to link it to anybody at the time. In 2020, the Honolulu Police contacted Parabon and provided the sample, which was later linked back to Trent. He died in 2013 from heart failure in Honolulu, and could not be arrested. |
| Robert Anthony Brooks | Murder of 17-year-old Michelle Koski | Snohomish, Washington, USA | 1990-08-25 | 2016-10-26 | Koski's DNA profile was submitted to GEDmatch and Family Tree DNA by Det. Jim Scharf, who was tasked with handling the cold case, allowing Parabon to work on it as well. They eventually narrowed the suspect list down to Brooks and his brother, and blood sample proved that the former was responsible. At the time of the crimes, he had recently been released from juvenile prison. Brooks died from natural causes in 2016, and thus could not be arrested. |
| Michael Jeffrey Mellus | Murder of 30-year-old Patricia Stichler | Sylvania, Ohio, USA | 1985-01-02 | 1989-03-22 | Mellus, a 17-year-old neighbor at the time of the crime, died in a car crash four years after the murder while serving in the Army. |
| Stephen Joseph Simcak | Murder of 25-year-old Nadine Madger | Willoughby, Ohio, USA | 1980-01-11 | 2018-06-15 | At the time of the crime, Simcak was serving in the Marine Corps. His guilt was confirmed after DNA was obtained from a deceased grandson, which concluded that Simcak was the one responsible for Madger's killing. He could not be arrested, as he died in 2018. |
| Scott Grim | Murder of 26-year-old Anna Kane | Perry Township, Pennsylvania, USA | 1988-10-23 | 2018 | DNA collected from Kane's clothing was later matched to a letter sent to the Reading Eagle, thought to be sent by her killer. Upon giving these samples for examination to Parabon, they were able to identify Grim as the killer. He could not be arrested, as he died from natural causes in 2018. |
| 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 | 2022-11-19 | 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., in 2019, but was found dead in his cell on November 19, 2022. Authorities believe he took his own life. |
| Joseph Norman Hill | Sexual assault and murder of 12-year-old Bradley "Brad" Bellino | Boardman, Ohio, USA | 1972-04-01 | 2019-07-03 | Hill was confirmed to be a 98% match to foreign DNA found on Bellino's body, but a full 100% could be ascertained as his body was cremated after his death from natural causes in July 2019. In June 2023, he was linked to the 1975 murder of 13-year-old David Evans, who was evidently stabbed to death in Boardman under similar circumstances. Police are currently investigating him for possible involvement in similar crimes committed around the Boardman area. |
| Elliott Lloyd Higgins | Multiple sexual assaults | Tuscaloosa, Alabama, and Colorado Springs, Colorado, USA | 1990 to 2004 | 2014 | Higgins, a convicted rapist whose convictions date back to the 1970s, was linked to three sexual assaults via his DNA, but could not be arrested as he died in 2014. Due to his profession as a music teacher that required him to travel extensively, investigators believe he may be responsible for more attacks around the country. |
| Frank Arthur Hall | Rape and murder of 6-year-old Ljubica Topic | Windsor, Ontario, Canada | 1971-05-14 | 2019-02 | Hall, a neighbor of the Topic family, was identified as the perpetrator in 2019, but his identity was not revealed until February 2023. He died in February 2019, before he could be arrested. |
| William Richard DeRoos | Rape and murder of 24-year-old Rita Curran | Burlington, Vermont, USA | 1971-07-19 | 1986-08-07 | DNA extracted from a cigarette butt linked DeRoos, who was Curran's neighbor at the time, to her rape and murder. He later moved to Thailand and lived as a Buddhist monk for some time, but eventually returned to the US, where he died of a drug overdose in San Francisco, California. Curran was previously believed to be a possible victim of serial killer Ted Bundy. |
| Forrest Clyde Williams III | Murder of 16-year-old Pamela Lynn Conyers | Millersville, Maryland, USA | 1970-10-16 | 2018-03-28 | Williams died of natural causes in 2018, before he could be arrested. His accomplice, Donald Willard, was identified in 2024, but is also deceased and cannot be tried. |
| Frank A. Rodriguez | Sexual assault and murder of 65-year-old Joyce Casper | Boise, Idaho, USA | 1987-10-13 | 2007 | This identification was made possible with the help of Identifinders International, another genetic genealogy company assigned to the case. Investigators are looking into the possibility that Rodriguez may have committed other crimes. |
| Bryan Scott Bennett | Sexual assault and murder of 23-year-old Cathy Sposito, and several sexual assaults | Prescott, Arizona, USA | 1987-06-13 | 1994-01 | The identification was made after his body was exhumed and DNA retrieved from cheek swabs taken from his brother and a daughter. Bennett shot himself in Kentucky in January 1994. |
| Tudor Chirila Jr. | Murder of 19-year-old Nancy Elaine Anderson | Waikiki, Hawaii, USA | 1972-01-07 | 2024-01-07 | Chirila was identified through comparing his DNA to that which has been found on the crime scene, and he was subsequently arrested at this home in Reno, Nevada. He died awaiting trial on second-degree murder charges. |
| Unnamed suspect | Attempted murder | Scott County, Indiana, USA | 1995-05 | 2003 | The suspect was identified via a familial DNA link, but his name was not released due to the fact that no formal charges can be filed due to the fact he is deceased. |
| Donald Willard | Murder of 16-year-old Pamela Lynn Conyers | Millersville, Maryland, USA | 1970-10-16 | 2010 | Died before he could be arrested. His accomplice, Forrest Clyde Williams, was identified in 2023, but is also deceased and cannot be tried. |
| William Kernan Jr. | Murder of 14-year-old Maria Honzell | Colorado Springs, Colorado, USA | 1977-02-07 | 2010 | Kernan, an acquaintance of the woman Honzell was babysitting for, had been at the apartment on multiple occasions. He died of natural causes in 2010, and thus cannot be arrested. |

#### 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. |
| Edwin Rodriguez | Wolf Creek Township, Pennsylvania, USA | 1980 (?) | 1980-11-06 | 2019 | A burning body found near the I-80 in Wolf Creek Township, Pennsylvania, on November 6, 1980, but beyond the fact that it appeared to be that of a young white male, nothing was known about the decedent. His DNA profile was later sent to Parabon, who identified the man as Edwin Rodriguez, originally from Chicago. Further investigation led to the identification of Nestor Quintanal, a friend of the Rodriguez family, as the most likely perpetrator in May 2022. He could not be arrested, as he died in Florida in 2002. |

| 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. |
| "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. She pleaded guilty to the crimes and was sentenced to 30 years imprisonment. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. In February 2020, police identified Forrest Ethington, Fiegener'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 Fiegener'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." |
| 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.

Investigation into his murder is ongoing. |
| 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. Authorities are seeking information to resolve her murder. |
| 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. The Clackamas County Sheriff's Office is investigating the case. |
| 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." |
| 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.

After finding no matches on various missing persons databases, the Oregon State Police Medical Examiner's Office contacted Parabon in 2018, and a sample was sent in 2021. Using their genetic technology, they linked the man's DNA to relatives in Oregon, who had reported him missing in 2008. Per their request, his identity is being withheld. |
| Sylvia Nicole Smith | Midland County, Texas, USA | 2000-02-14 | 2013-08-01 | 2022-06-27 | On August 1, 2013, oil workers inspecting an oilfield found partial human remains, who were believed to belong to a teenager or young woman of African-American descent. Due to the circumstances she was found in, it was believed that she was the victim of a homicide. The remains were sent for identification at DNA Labs International and later to Parabon NanoLabs, which helped identify the decedent as 16-year-old Sylvia Nicole Smith. Investigations into her death are ongoing. |
| Angela Mason | Norman, Oklahoma, USA | 2008 | 2008-08-31 | 2022-08-31 | On August 31, 2008, several fishermen who were near the Lake Thunderbird reservoir found a shallow grave containing human remains. After several attempts to identify the decedent, most prominently via her distinctive tattoo, a DNA sample from her remains was sent to Parabon, who eventually identified her as 25-year-old Angela Mason. A member of the Cherokee Nation, she was a divorced mother of four who was last seen near Moore in the spring of 2008, and her death is being treated as a homicide. |

Soden, a transient, was identified via DNA with the help of Florida Department of Law Enforcement and Fort Myers' cold case unit. Like with the other victims, murderer Daniel Conahan is the prime suspect in his killing. |
| John Barber | Griswold, Connecticut, USA | 1843 | 1990 | 2022-11 | During excavations of an old farm cemetery, archeologists took notice of one coffin in particular - branded "JB 55" - due to the fact that the skeleton had its skull separate from the body and placed on the chest, a practice associated with the New England vampire panic and the belief that this was a way to prevent deceased people from becoming vampires. In November 2022, the skeleton was identified as belonging to John Barber, a farmer who had succumbed to tuberculosis in 1843. |
| Maria Telles-Gonzalez | Yemassee, South Carolina, USA | 1990s | 1995-05-24 | 2022-12-01 | Her body, clad only in underwear, was found in a drainage ditch. While coroners determined that she had been strangled to death, they were unable to identify the decedent at the time. Using DNA extracted from previous identification attempts, a volunteer member at Parabon located Telles-Gonzalez's biological son and used his DNA sample to confirm that the victim was his mother. She was last seen in Kissimmee, Florida, and allegedly planned to travel to Puerto Rico, and authorities are currently seeking to identify two potential suspects in her murder. |
| Philip Kahn | Jonesport, Maine, USA | 2000 | 2000-07-24 | 2023-01-11 | The skeletal remains of an elderly man were found floating in the Atlantic Ocean off the coast Maine, but authorities were unable to identify him at the time. Through a joint effort with the FBI and OCME, Parabon were able to match fingerprints and dental records to those of the 84-year-old Kahn, a resident of Las Vegas, Nevada, who had been reported missing in 2000. It remains unclear how and why he ended up in Maine. |
