A woman killed in a 1987 crash on the Pennsylvania Turnpike spent 35 years known only as “Somerset Jane Doe” before forensic genetic genealogy work traced her back to a name: 26-year-old Linda Jean McClure of Indiana, Pennsylvania. The identification, announced by Pennsylvania State Police in January 2023, closed one of the state's longest-running cold cases and relied on DNA science developed at a laboratory hundreds of miles away, in the Houston area.
How a Houston-Area Lab Cracked a Pennsylvania Cold Case
According to KHOU, the identification was made possible through forensic genetic genealogy performed by a Houston-area DNA lab, more than three and a half decades after McClure died. That lab was Othram Inc., a company founded in The Woodlands, Texas that operates a private laboratory purpose-built for forensic-grade genome sequencing, building comprehensive DNA profiles from degraded human remains, per the Commonwealth of Pennsylvania. The testing only became possible after the Pennsylvania Turnpike Commission agreed in August 2022 to pay for the forensic genetic genealogy work with Othram, according to the same state announcement — a reminder that these breakthroughs often hinge on which agency is willing to foot the bill.
Unlike the FBI's CODIS database, which matches DNA only against samples already on file from known offenders or missing persons, forensic genetic genealogy builds out multi-generational family trees using consumer DNA databases to close in on unidentified remains. Research published in December 2025 found that CODIS yields identifications in just 13% to 16% of unidentified remains cases, while forensic genetic genealogy achieves roughly a 50% resolution rate in NamUs casework, per PubMed Central. That gap helps explain why state police and medical examiners increasingly turn to private labs like Othram rather than relying solely on federal databases.
A Backlog of More Than 11,000 Unidentified Remains
The Somerset case is one piece of a much larger national puzzle. Medical examiners and coroners across the country are holding more than 11,000 sets of unidentified human remains, even as roughly 600,000 people are reported missing every year, according to MPR News. Every name recovered through genetic genealogy chips away at that backlog, but the technology's cost and specialized equipment still mean most cases depend on outside funding, as was true for the Pennsylvania Turnpike Commission's arrangement with Othram.
Texas Cases Show a Pattern of DNA-Driven Closures
Othram's home turf has generated its own string of resolutions. In July 2026, the Harris County Institute of Forensic Sciences partnered with Othram to try to identify a Houston Jane Doe fatally struck by a vehicle on the East Freeway back in May 1980, according to KHOU. That same month, Texas officials confirmed that human remains found near a Missouri City trail in 2020 belonged to Kristen Galvan, a 15-year-old from Spring, Texas who had been a victim of human trafficking. The case echoes an earlier Texas breakthrough: in November 2021, authorities identified the 1980 “Walker County Jane Doe” murder victim found in Huntsville as 14-year-old Sherri Ann Jarvis of Minnesota, ending a 41-year mystery, per Click2Houston.
Hoodline has tracked this wave of DNA-driven identifications closely. In May, Texas investigators used Othram's sequencing pipeline combined with 1981 fingerprint records to name a Fort Worth landfill victim as Joyce Ann Hinson. Just days ago, Hoodline also reported on a similar 35-year-old cold case involving a Frederick-area Jane Doe found along I-270 in Maryland, where forensic genetic genealogy is likewise being pursued to establish an identity.
States Begin Writing Rules for a Fast-Moving Science
As forensic genetic genealogy spreads from one cold case to the next, lawmakers are starting to catch up. Maryland has enacted legislation that formally defines forensic genetic genealogy in state statute, establishing legal guidelines for how police can use consumer DNA databases and family trees in cold case investigations. No comparable statute is noted for Pennsylvania or Texas in connection with the McClure case, leaving the legal framework for how such testing is authorized state by state still something of a patchwork as the technology's use accelerates.
For Linda Jean McClure's family, the science ultimately delivered what a name-only headstone and 35 years of silence could not: an answer. Her case now stands alongside a growing list of Texas- and Othram-linked identifications, from Fort Worth to Huntsville to Missouri City, that together illustrate how a single Woodlands-based lab has become a recurring name in cold cases stretching far beyond its home state.
