Halloween 1981: Ronald Sisman and Elizabeth Platzman were murdered in their apartment located near Greenwich Village. The couple was severely beaten before being shot in the head, execution-style, and the apartment was completely ransacked. Sisman was rumored to be involved in drugs, so authorities believed that could have been the motive for the killings. When, it's claimed that David Berkowitz a.k.a. “Son of Sam” let the couple killed because Sisman possessed a footage of one of his killings.
