Mark David Chapman (born May 10, 1955) is an American man who murdered English musician John Lennon in New York City on December 8, 1980. As Lennon walked into the archway of The Dakota, his apartment building on the Upper West Side, Chapman fired five shots at the musician from a few yards away with a Charter Arms Undercover .38 Special revolver. Lennon was hit four times from the back. He was rushed to Roosevelt Hospital and pronounced dead on arrival. Chapman remained at the scene following the shooting and made no attempt to flee or resist arrest.
Raised in Decatur, Georgia, Chapman had been a fan of the Beatles, but was incensed by Lennon's lavish lifestyle and public statements, such as his remark about the band being "more popular than Jesus" and the lyrics of two of his later songs "God" and "Imagine". In the years leading up to the murder, the J. D. Salinger novel The Catcher in the Rye took on great personal significance for Chapman, to the extent that he wished to model his life after the novel's protagonist, Holden Caulfield. Chapman also contemplated killing other public figures, including David Bowie, Johnny Carson, Paul McCartney, Ronald Reagan, and Elizabeth Taylor. He had no prior criminal convictions and had recently resigned from a job as a security guard in Hawaii.
Following the murder, Chapman's legal team intended to mount an insanity defense based on the testimony of mental health experts who said that he was in a delusional psychotic state at the time of the shooting. However, he was more cooperative with the prosecutor, who argued that his symptoms fell short of a schizophrenia diagnosis. As the trial approached, Chapman instructed his lawyers that he wanted to plead guilty based on what he had decided was the will of God. The judge granted Chapman's request and deemed him competent to stand trial. He was sentenced to a prison term of twenty years to life with a stipulation that mental health treatment would be provided.
Chapman refused requests for press interviews during his first six years in prison; he later said that he regretted the murder and that he did not want to give the impression that he killed Lennon for fame and notoriety. He ultimately supplied audiotaped interviews to journalist Jack Jones, who used them to write the investigative book Let Me Take You Down: Inside the Mind of Mark David Chapman in 1992. In 2000, Chapman became eligible for parole, which has since been denied thirteen times. His life was dramatized in the films The Killing of John Lennon (2006) and Chapter 27 (2007).
