Martyn Doyle-Jacobs (26 December 1941 – 27 December 1969), was a British actor, singer-songwriter, producer and mass murderer. He was known for his extreme roles as serial killers and child rapists. During the final years of his life, Jacobs put on a lot of weight and because of this, began taking drugs. Ten days before his death, he and a friend shot and killed twenty people inside the West End Mall in Reading, England. Three police officers were killed during the process. Jacobs was surrounded by police on December 27, 1969. As they proceeded to slowly walk into his apartment, Jacobs shot himself in the right temple, dying immediately.
