Mark David Chapman is an American prison inmate who pled guilty to murdering John Lennon on December 8, 1980. Chapman shot Lennon outside The Dakota apartment building in New York City. Chapman fired at Lennon five times, hitting him four times in his back. Chapman remained at the scene reading J. D. Salinger's novel The Catcher in the Rye until the police arrived and arrested him. Chapman repeatedly said that the novel was his statement. Chapman's legal team put forward an insanity defense based on expert testimony that he was in a delusional and possibly psychotic state at the time, but nearing the trial, Chapman instructed his lawyer that he wanted to plead guilty, based on what he had decided was the will of God. Judge Edwards allowed the plea change without further psychiatric assessment after Chapman denied hearing voices, and sentenced him to a prison term of twenty years to life with a stipulation that mental health treatment be provided. Chapman was imprisoned in 1981 and has been denied parole eight times amidst campaigns against his release. [More at Wikipedia]
