David Richard Berkowitz (born Richard David Falco; June 1, 1953), also known as Son of Sam and the .44 Caliber Killer, is an American serial killer convicted of a series of murders that began in July, 1976. Perpetrated with a .44 caliber Bulldog revolver, the killings continued for over a year, leaving six victims dead and several others wounded. The highly publicized shootings terrorized New York City and achieved worldwide notoriety. After his arrest by New York police in August, 1977, Berkowitz was indicted for eight separate shooting incidents. Berkowitz confessed to all of them and claimed that he was commanded to kill by a demon that possessed his neighbor's dog. He subsequently confessed to multiple acts of arson in the city, all previously unidentified with him. Berkowitz has been imprisoned since his arrest and is serving six life sentences consecutively.
