At 10:58pm on 8th December 1980, in the archway of the building in which he lived in New York, the musician and political activist John Lennon was shot and killed by an obsessed fan. Lennon sustained four major gunshot wounds and was pronounced dead on arrival at Roosevelt hospital, he was just 40 years old. His killer, Mark David Chapman, was sentenced to serve a minimum of 20 years in prison with a stipulation that mental health treatment is provided.
The Day John Lennon Died is a 2010 British documentary about the events of that fateful day, featuring contributions from some of those who knew Lennon best including his wife Yoko Ono, friend Cilla Black, and archive footage of his former band mates Ringo Starr, George Harrison, and Paul McCartney.
The writer Jack Jones corresponded with Mark David Chapman, and interviewed him face-to-face, in order to try and understand the mind of the killer and his motives. He subsequently published the book Let Me Take You Down: Inside The Mind of Mark David Chapman, available to purchase in paperback or hardback (not currently available on kindle).
