McDonald retired as Chief of Detectives for the Los Angeles County Sheriff's Department. He was the inventor of the Identikit and the author of several law-enforcement textbooks. He taught at the University of California in Los Angeles, the University of Southern California, the University of Oklahoma, and the University of Louisville, KY. Widely respected in police circles, McDonald was often sought out as a consultant on difficult cases throughout the country. In 1964, he was granted leave to serve as director of security control for Senator Barry Goldwater during his presidential campaign. He studied at the FBI academy and occasionally handled special assignments for the CIA. It was during a meeting with his CIA "handler" at CIA headquarters that he first encountered the man he called Saul—the hired assassin who pulled the trigger, killing President John F. Kennedy. McDonald devoted more than eight years and traveled more than 50,000 miles through ten countries in his successful effort to confront the killer and hear his fateful confession.view less
