On March 1, 1983, 23-year-old Louis Petrizzo was fatally shot outside his residence on East 54th Street in the Mill Basin neighborhood of Brooklyn. He sustained six gunshot wounds to his chest. Reports link him to the Gambino crime family’s DeMeo crew, which was in a period of internal turmoil at the time; crew leader Roy DeMeo had been found dead in the trunk of his car months earlier.

Investigators and commentators have treated Petrizzo as a marked man, allegedly targeted because associates suspected he might cooperate with law enforcement. The prevailing theory described in accounts is that his killing was a preemptive measure to prevent cooperation and protect the crew’s operations. Official records do not show identified suspects or arrests, and the murder remains unsolved.

Did anyone in Mill Basin or with ties to the DeMeo crew have information about Petrizzo’s movements or associates in early 1983?
