Beginning of the End

John Ono Lennon and Mark David Chapman.

Mark David Chapman  the man who murdered English musician and activist John Lennon on December 8, 1980 in New York City. Chapman shot Lennon four times in the back outside The Dakota apartment building, in the presence of Lennon's wife Yoko Ono and others. 

Around 5:00 p.m., Lennon and Ono left The Dakota for a recording session at Record Plant Studios. As they walked towards their limousine on the curb, Chapman shook hands with Lennon and held out a copy of Lennon's new album, Double Fantasy, for him to sign. Photographer Paul Goresh was present when Lennon signed Chapman's album and took a photo of the event.[11] Chapman reported that, "At that point my big part won and I wanted to go back to my hotel, but I couldn't. I waited until he came back. He knew where the ducks went in winter, and I needed to know this" (a reference to The Catcher in the Rye). Around 10:49 p.m., the Lennons' limousine returned to the Dakota. Lennon and Ono passed by Chapman and walked toward the archway entrance of the building's courtyard. From the street, Chapman turned and fired five hollow point bullets from a Charter Arms .38 revolver that he had purchased in Hawaii, four of which hit Lennon's back and shoulder. One of the bullets pierced Lennon's aorta, the largest and most important artery in the human body, causing very severe blood loss by aortic dissection.
