Cold Case Murder Victim Is Finally Identified as a Navy Veteran 54 Years Later Thanks to New Technology

For more than half a century, a set of remains discovered alongside an Oregon highway held only secrets—until new DNA technology finally gave the victim back his name and a family the chance to seek justice.

Authorities say the bones were found in 1972 off Highway 101 near Brandon, Oregon, with injuries consistent with homicidal violence. At the time, investigators had no way to identify the man. That changed when the Coos County Sheriff’s Office teamed up with the Oregon Cold Case Collective, a volunteer-driven group using cutting-edge forensic tools to crack decades-old mysteries.

The breakthrough came through Investigative Genetic Genealogy, a technique that traces DNA through family trees. In March 2025, the FBI joined the effort. By July 2026, the remains were identified as Armes Henry Lahti, a Navy veteran and avid fisherman from Astoria, Oregon.

He served during World War II.

Lahti’s family told officials his nickname was “Mousy”—not because he was small, but because he was a large, gentle man who loved the sea and was deeply proud of his service. He disappeared in 1965 after a dispute at a local bar, reportedly walking off with a rifle. His remains weren’t found for seven years.

The identification process took years of persistence. In 2014, DNA was extracted and entered into the national CODIS database with no matches. Then, using grant funding, researchers tried single nucleotide polymorphism profiling and forensic genetic genealogy.

It wasn’t until 2025 that Othram, a private lab, successfully extracted a full DNA profile, revealing the victim was 100 percent Finnish ancestry and born in 1909.

“This long-awaited identification reflects years of dedicated work, collaborative science, and advances in modern genetic genealogy,” said state forensic anthropologist Dr. Hailey Collord-Stalder.

Now the Coos County Sheriff’s Office is asking the public for help. They believe someone out there knows what happened to Armes Henry Lahti. Investigators are hoping to finally bring justice to a man who spent decades waiting to be remembered.

If you have any memory—no matter how small—of a bar dispute in 1965 or a man with a rifle who never came home, would you come forward?
