EVERETT, Wash. (AP) — Detectives have used genetic genealogy to identify a long-unknown shooting victim whose body was found in a Snohomish County lake more than a quarter-century ago.

The Snohomish County Sheriff’s Office said Wednesday the body was that of Rodney Peter Johnson, who was found in Lake Stickney in 1994. His family last saw him in late 1987 or early 1988 when he left on a camping trip.

Investigators say the victim had been shot in the head, and his body had apparently been weighted down in the lake for more than six years before it floated to the surface and was discovered.
