While returning to his New York hotel with wife Yoko Ono one evening, John Lennon was shot and killed by Mark David Chapman, a delusional and possibly psychotic Beatles fan.

He has since been denied parole on several occasions. Rather than flee the scene after shooting Lennon, Chapman hung around and read from what book until police arrived? Discuss
