The "Ted Murders" marked the beginning of Robert Keppel's career as a detective. Witnesses from Lake Sammamish State Park provided information regarding a man named "Ted" who had talked to two young women that were declared missing. During the investigation, Keppel narrowed down a large list of suspects until he was left with 25, including Ted Bundy. He confronted Bundy, but Bundy dismissed the conversation. Before Keppel could speak with him again, Bundy had already been arrested and fled custody. After moving on from the "Ted Murders," Keppel decided to return to a doctorate program at University of Washington. While completing this 12-year program, he took the position as chief investigator for Washington State Attorney General's office. In this position, he investigated other crimes like the disappearance of Captain Rolf Neslund, and the death of Donna Howard. Keppel was asked to assist in the Green RiverTask Force for the investigation of a set of murders in Washington. By 1984, Ted Bundy began writing letters to Robert Keppel in hopes to help in the investigation of the Green River Killer. This correspondence led to interviews between the two, which resulted in Bundy confessing to his unidentified crimes days before his execution.
Later life
Keppel retired as chief criminal investigator for the Washington State Attorney General's Office. He joined the faculty of the Seattle University., Keppel was an associate professor of criminal justice at Sam Houston State University, and currently teaches there via teleconference. In 2007, Keppel joined the University of New Haven as an associate professor of criminal justice. Keppel is author of The Riverman: Ted Bundy and I Hunt for the Green River Killer, made into a made-for-TV movie of the same name in 2004, starring Bruce Greenwood as Keppel and Cary Elwes as Bundy. He is also the author of many textbooks regarding criminal justice and related topics.
