36 years ago today, Mark David Chapman shot John Lennon outside his residence, The Dakota, in New York City. Earlier that day, Lennon had signed an album for Chapman, who had been waiting outside Lennon’s home. After the attack, Chapman remained at the scene reading J.D. Salinger’s best-selling novel, The Catcher in the Rye. Lennon was pronounced dead on arrival at Roosevelt Hospital at 11:15pm. Chapman pleaded guilty to the killing in court and remains in prison to this day.
