It was this night, Friday, June 13, 1975, that the DeMeo crew is first known to have been involved with murder and dismemberment. While first-hand accounts of the incident are unavailable, information provided by crew members who cooperated with the government years later as well as the actual remains of Andrei Katz provided clues that were used by law enforcement as well as author Jerry Capeci to reconstruct the events. Andrei was stabbed multiple times in the heart with a butcher knife, presumably by Rosenberg in revenge for the shooting that had ruined his face.
