Green River Killer’s Last Unknown Victim Identified

Since 2003, “Bones 20,” the remains, have been unidentified despite significant efforts. Othram, a forensic genetic genealogy lab, identified the victim as Tammie Liles using advanced DNA testing.

A dental record match to remains found near Tigard, Oregon identified Tammie Liles as a victim in 1988. Two anonymous ladies, Liles and Angela Girdner, were found dead near the Tualatin Golf Course in Tigard, Oregon, in 1985, according to the King County Sheriff’s Office. Gary Ridgway, the Green River Killer, first denied murdering them. Later, he took investigators to a corpse he claimed he left.

Ridgway, convicted of killing 49 people and confessed to 71, pled guilty to murdering “Bones 20,” Denise Bush, and Shirley Sherrill in November 2003. Ridgway terrorized Washington state in the 1980s. Investigators suspect he has more victims despite his convictions.
