Serial “Green River Killer” Gary Ridgway told KOMO radio that the Green River Task Force mostly kept him in a van in 2003 when he directed the police to sites in the Seattle area where he dumped numerous bodies in the 1980s. Ridgway now says he’d like to revisit every site on foot and says he could have had as many as 80 victims that were never found. Watch a riveting documentary on Gary Ridgway:

Ridgway was arrested in 2001 after advances in DNA technology helped authorities to link a 1987 saliva sample to some of the bodies. He pleaded guilty to 48 murders two years later, and agreed to assist authorities in locating as many remains as possible. He also pleaded guilty to a 49th murder in 2011.

“Ridgway is a sociopath and pathological liar” who likes notoriety, said King County sheriff’s Sgt. Katie Larson, who was a key member of the Green River Task Force. “It’s possible he killed more than the 49 women for which he was convicted”, she said Tuesday. However, investigators are very confident they did everything possible to recover all of his victims.

The SeattlePI.com reports that “The contentious plea deal struck by former King County Prosecutor Norm Maleng required Ridgway to admit guilt in all his King County killings. In exchange, Maleng agreed not to seek a death sentence, so long as Ridgway pleaded guilty to the charges. Additional charges elsewhere in the state or country, which are not precluded by the agreement, have not followed. The serial killer remains a suspect in dozens of other disappearances, but has yet to face charges elsewhere.”

KOMO plans to air more of the exclusive interview with Ridgway, 64, who is serving a life sentence at the Washington State Penitentiary in Walla Walla.
