Chapman, who was 25 at Lennon's death, shot the Beatles star four times in Manhattan in December 1980 - as his wife looked on.

Chapman also believes he should have been given the death penalty, according to the transcript.
He told officials: "I want to reiterate that I'm sorry for my crime. I have no excuse. It was for self-glory.
