Dr. Stephan Lynn was in charge of the emergency room at Roosevelt Hospital in New York on the night of December 8, 1980. He had just arrived home after a 15-hour shift when he received a call from the hospital about a man coming in with gunshot wounds. He returned to the ER in time to work on the victim, who turned out to be John Lennon. At one point, he cracked Lennon's chest and literally held his heart in his hands in an unsuccessful attempt to revive him.
Dr. Lynn told this story on my show to mark the 25th anniversary of that night. I also asked him why no gruesome memorabilia from that night has ever shown up on eBay or at Beatles shows, and about his personal connection to Lennon before that horrible event.
