"The best-known event associated with The Catcher in the Rye is arguably Mark David Chapman's murder of John Lennon in 1980.[14] Chapman identified with the novel's narrator to the extent that he wanted to change his name to Holden Caulfield. On the night he shot Lennon, Chapman was found with a copy of the book in which he had written "This is my statement" and signed Holden's name.[15] Later, he read a passage from the novel to address the court during his sentencing.[16] Daniel Stashower speculated that Chapman had wanted Lennon's innocence to be preserved by death, inspired by Holden's wish to preserve children's innocence despite Holden's later realization that children should be left alone.[16]

"After John Hinckley Jr.'s assassination attempt on Ronald Reagan in 1981, police found The Catcher in the Rye in his hotel room.[17] Hinckley's possession of the novel was later dismissed as an influence, as a half dozen various other types of books were also discovered in his possession.

"Robert John Bardo, who murdered Rebecca Schaeffer, was carrying the book when he visited Schaeffer's apartment in Hollywood on July 18, 1989 and murdered her."

Two carried it, one had it back in his hotel room. And all 3 were in the 80s.
