John Lennon

On the night of December 8, 1980, Mark David Chapman murdered John Lennon outside of the Dakota Building in New York City while clutching a copy of the book Catcher in the Rye. But was Chapman brainwashed? Lennon was hounded for years by the FBI for his peaceful support of the Vietnam War; because of this, many conspiracy theorists believe Chapman could have been a victim of the CIA's MK Ultra program, which was rumored to have turned law-abiding citizens into willing assassins.
