Roy Albert DeMeo was an American mobster in the Gambino crime family of New York City. He headed a group known as the "DeMeo crew", which consisted of approximately twenty associates involved in murder, car theft, drug dealing, prostitution and pornography. The DeMeo crew became notorious for the large number of murders they committed and for the grisly routine they employed to dispose of bodies, which became known as "the Gemini Method". The crew is believed to be responsible for up to 200 murders, many of which were committed by DeMeo himself.
