King County Police Major Bob Kraske and Detective David Reichert (later elected County Sheriff) led the initial investigation of Bonner's murder. In consultation with other police departments, they linked the Bonner killing with the earlier unsolved murders of Wendy Coffield and Leann Wilcox, and reached the conclusion that a serial killer might be stalking street prostitutes in the south King County area. As new victims turned up in or near the Green River, King County Executive Randy Revelle and new Sheriff Vernon Thomas organized a special Green River Task Force, first directed by Frank Adamson.
The list of suspected Green River victims rose to 49 over the next two years. Until the arrest of Ridgway, formal charges were never brought against any suspect despite the expenditure of $15 million and tens of thousands of staff hours, the assistance of famed profiler Bob Keppel and the Federal Bureau of Investigation, and tips from psychics and citizens. The last victim, Cindy Smith, was found in March 1984. It was subsequently presumed that that the killer had left King County. County Executive Tim Hill disbanded the Green River Task Force in 1989, but the case remains open.
Gary Leon Ridgway, 52, a longtime resident of the area, was arrested on November 30, 2001. DNA evidence ties Ridgway to four of the cases, and circumstancial evidence to several others. Ridgway, a truck painter raised near SeaTac, is a Tyee High School graduate. He has been a suspect for a long time, but before now, detectives had not found adequate evidence to build a case against him.
