A partial human cranium found by a logging crew near Spooner Summit in May 1994 has finally been given a name: Alan Don Bishop, a man who vanished from Salt Lake City 42 years ago while reportedly hitchhiking toward Oregon by way of California. The identification, confirmed through advanced DNA genealogy, closes a case that sat unresolved for more than three decades in the mountains above Carson City.
Bishop's family last heard from him in July 1984, when he sent word he was traveling to Oregon via California, according to the KOLO | 8 News Now report on the case. Communication and bank activity from Bishop stopped after that contact, prompting his family to report him missing. The outlet notes Bishop was reported to have experienced mental health issues and was known to travel by hitchhiking, details that help explain how a man from Utah ended up in the Nevada mountains with no clear trail for investigators to follow.
A Skull With No Other Clues
The remains themselves offered investigators little to work with for decades. Logging workers discovered the partial cranium on May 26, 1994, at a mountain work site in the Spooner Summit area, according to the Carson City Sheriff's Office. Deputies searched the surrounding area at the time but recovered no additional skeletal remains or personal belongings, leaving early forensic anthropologists able to determine only that the skull belonged to an adult male.
Investigators also determined the remains showed no signs of trauma, per the Carson City Sheriff's Office, a finding that leaves the exact cause and circumstances of Bishop's death unresolved even after his identity has been confirmed. Spooner Summit sits along U.S. Highway 50 in the Carson Range at an elevation of 7,146 feet, a high mountain pass connecting Carson City to the Lake Tahoe basin across Douglas County, according to Sierra Mountain Passes.
How Genetic Genealogy Cracked the Case
The breakthrough came from a specialized DNA lab. Scotts Valley-based Astrea Forensics extracted a viable DNA sample from the degraded skull fragment and generated a single nucleotide polymorphism profile needed for advanced genealogical matching, the Carson City Sheriff's Office said. Astrea Forensics, founded in 2019 by paleogeneticists, applies ancient-DNA recovery methods to pull usable genetic profiles from heavily degraded skeletal remains that fail traditional forensic testing, according to ISHI News.
From there, researchers at the Ramapo College Investigative Genetic Genealogy Center identified Bishop as a candidate match, and the volunteer-led Retired Investigators Guild located his living full sibling to confirm the relationship through mitochondrial DNA testing, per the sheriff's office. The Ramapo College center, established in New Jersey in 2022 as the nation's first university-based IGG center, partners with the Guild to provide pro bono genetic genealogy work to law enforcement agencies, according to Ramapo College. Bishop's identity was ultimately confirmed through that sibling's DNA sample, KOLO | 8 News Now reported.
Case Remains Open Despite Identification
The Washoe County Regional Medical Examiner's Office formally affirmed the genetic identification in August 2026, and Carson City Sheriff's Detective B. Torres remains assigned to handle any continuing leads in the case, according to the sheriff's office. Investigators are still hoping to piece together more of Bishop's final travel route through Nevada, even though his identity is now settled.
Bishop's case fits into a wider pattern of Nevada cold cases being cracked open by genetic genealogy in recent years. Hoodline previously reported on the naming of Elko's 'Shafter Jane', identified as Marion Hertha Alexander 32 years after her remains were found in 1992. Nationally, FBI statistics compiled by federal law enforcement estimate that more than 250,000 homicides and unidentified remains cases across the country have gone unsolved since 1980, according to The Retired Investigators Guild, underscoring how significant a single successful identification like Bishop's can be against that backlog.
