COOS COUNTY, Ore. (28 July 2026) – The Oregon State Medical Examiner’s Office Human Identification Program, working closely with the Coos County Sheriff’s Office Cold Case Unit, has successfully identified a man whose remains were discovered in 1972 near Highway 101. After decades of stalled leads and inconclusive testing, advanced forensic genetic genealogy finally provided the answers investigators had long sought, revealing the decedent as Armes Henry Lahti.
On August 26, 1972, the skeletal remains of what were believed to be an older male were discovered in a brushy area off Highway 101 north of the Highway 42 junction in Coos County. The decedent was found with upper and lower denture plates and multiple articles of clothing. Unfortunately, none of the items provided any clues to the man’s identity. Due to other evidence at the scene, the case was treated as a homicide.
Attempts at identifying the decedent were made throughout the ensuing years. In 2014, DNA was extracted and sequenced for upload to the Combined DNA Indexing System (CODIS) by the University of North Texas Human Identification Center; however, there were no matches. Using National Institute of Justice grant funding, the remains were submitted for Single Nucleotide Polymorphism (SNP) profiling and forensic genetic genealogy to several companies. Unfortunately, due to insufficient DNA, these efforts were unsuccessful. SNP profiling detects specific genetic markers to determine a unique genetic fingerprint.
In 2025, the Coos County Sheriff’s Office Cold Case Unit submitted further evidence to Othram, Inc. who successfully extracted and sequenced an SNP profile. The profile indicated that the decedent was of 100 percent Finnish ancestry. The profile was turned over to the Federal Bureau of Investigation and a probable candidate for the decedent was developed.
Family reference testing was completed, and the decedent has been confirmed as Armes Henry Lahti (born 1909).
State Forensic Anthropologist Hailey Collord-Stalder, Ph.D., said, “This long‑awaited identification reflects years of dedicated work, collaborative science, and advances in modern genetic genealogy.” She continued, “This outcome would not be possible without the ongoing cooperation among multiple law enforcement agencies, private scientific partners, and volunteers committed to resolving cold cases.”
The Coos County Sheriff’s Office Cold Case Unit is continuing to work the case and anyone with information is asked to call 541-396-7800 to speak with an investigator.
