More than five decades after a Montana teenager vanished on a trip through the Pacific Northwest, investigators say they finally know his name. Skeletal remains found near Williams, Oregon, in 1978 have been formally identified as Mark Smith, who disappeared in 1974 while traveling. The identification, the result of modern DNA extraction and genealogical sleuthing, returns an identity to remains long known only by a site label. Officials told reporters there is no current evidence of foul play, although the investigation into how he died is still open.
The case began on May 9, 1978, when a logging crew working near Holcomb Peak discovered a cranium and part of a scapula, along with a piece of shirt and the remnants of a brown sweater. At the time, investigators could not make a positive identification and the file went cold. The remains were eventually sent in 2020 to the University of North Texas for DNA extraction. From there, the State Medical Examiner’s Human Identification Program coordinated with DNA Labs International and other partners to pursue forensic genetic genealogy. Those efforts led detectives to living relatives and, investigators say, a match that confirmed the remains as Smith, as reported by KPTV.
Genetic genealogy unlocked the lead
Investigators say the real breakthrough arrived in September 2025. Genealogists had been wrestling with an incomplete family tree when a consumer DNA kit landed in an ancestry database and produced a crucial lead. Oregon State forensic anthropologist Hailey Collord Stalder told KPTV that when the kit showed up, the genealogist’s reaction was, “Oh my gosh, I can finally build a tree.” That new branch prompted investigators to collect DNA swabs from family members and run confirmatory testing that, officials say, matched Smith.
How labs turn tiny bone scraps into answers
Forensic investigative genetic genealogy combines SNP or whole genome sequencing with traditional genealogical research to locate distant relatives and rebuild family trees from degraded samples. Private laboratories now run in house FIGG pipelines, with sequencing and bioinformatics designed to pull usable genetic profiles from bone and other old or compromised evidence, capabilities described by DNA Labs International. Investigators say those tools were decisive in finally moving this cold case forward.
Smith’s family was notified after investigators completed the testing. Relatives reported a mix of shock and grief at finally getting answers after decades of uncertainty. The State Medical Examiner’s Office is working with the family on arrangements while the inquiry into Smith’s cause of death continues. With the identification, the remains once known only as the Holcomb Peak Doe are again recognized by a name.
