On December 8, 1980, Mark David Chapman shocked the world by murdering 40-year-old musician, former member of The Beatles and activist, John Lennon, outside The Dakota, his New York apartment building. Chapman's motives were fabricated from pure delusion, fueled by an obsession with the fictional character Holden Caulfield and his similar misadventures in J.D. Salinger's "The Catcher in the Rye". In one instant, an anonymous, socially awkward and mentally unstable 25-year-old fan of The Beatles, who had fluctuated between idealizing Lennon and being overcome with a desire to kill him, altered the course of the history of music.
