The workplace nickname of LAPD special investigator, John St. John (Jack Warden) on the police drama JIGSAW JOHN/NBC/1976. The series ran for 15 weeks.
He earned the nickname “Jigsaw John” because of the methodical way he pieced clues together at the scene of a crime.
Note: The TV series was based on the legendary Los Angeles homicide detective John St. John who investigated more than 1000 murders (and solved two-thirds of them), including such murder cases as The Black Dahlia and the Freeway Killer.
A year after he joined the LAPD in 1942, John was attacked from behind by a juvenile prisoner wielding an iron bar ripped from a jail bunk and consequently it left him blind in one eye.
“He always solved his cases by what he called ‘the pyramid effect,’ … you start with a wide base of possibilities and you eliminate, eliminate, eliminate. When you get to the top, that’s the guilty person.”
According to an article in the Los Angeles Times (05/04/1995), “In real life, St. John wasn’t like most of the detectives you see on television. He was fatter than most, shorter than most and walked with a tired shuffle. He had a gold tooth in front and usually carried a battered black attache case. He never shot anyone. And at the time of most of his celebrated cases, he was older than most.”
In 1995, John St. John (age 77) died of pneumonia and pancreatic cancer at a hospital in West Covina, California.
