David Berkowitz

David Richard Berkowitz (born Richard David Falco; June 1, 1953), also known as the Son of Sam and the .44 Caliber Killer, is an American serial killer convicted of a series of shooting attacks that began in New York City in the summer of 1976, perpetrated with a .44 caliber Bulldog revolver. He killed six victims and wounded seven others by July 1977. As the toll mounted, Berkowitz eluded a massive police manhunt while leaving brazen letters that mocked the police and promised further crimes, highly publicized in the press. He terrorized New York and achieved worldwide notoriety.
