David Richard Berkowitz  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 the summer of 1976. Perpetrated with a .44 caliber Bulldog revolver, the shootings continued for over a year, leaving six victims dead and seven others wounded. As the toll mounted, Berkowitz eluded a massive police manhunt while leaving brazen letters which promised further murders. Highly publicized in the press, the killings terrorized the people of New York City and achieved worldwide notoriety.

One page typed letter (on stationary sized paper) signed David in Pen. Berkowitz included several religious pamphlets with the letter which are also included. We are also including a CD titled 'Testimoney Profiles in Faith' that was also sent to the recipient at Berkowitz's request but was sent from the publishing company.
