The last unknown human remains associated with the Green River Killer Gary Ridgway were identified by a forensic sequencing lab contracted by the King County Sheriff's Office (KCSO). The remains belong to a victim of Ridgway who was already identified named Tammie Liles. This means there are no other unidentified remains connected to the Green River case, according to KCSO. Liles' remains were discovered in 1985 near the Tualatin Golf Course near Tigard, Oregon, alongside the remains of another victim. Ridgway was interviewed about those bodies and the bodies of two other women by detectives in 2002 and 2003. He admitted to moving two of the women from Washington to Oregon but denied responsibility for Liles' death and for the other woman who was found with her. In 2003, Ridgway led detectives to a site on Kent-Des Moines Road where he said he left a victim's body. A search of the area turned up several bones and some teeth, but a skull and most major bones were absent. Samples were sent to the University of North Texas, which obtained a DNA profile of the victim. That profile was uploaded to a national database. Those remains were labeled Bones #20 by investigators.
