As Piazza sat in his car listening to the gas pump ding, I like to imagine him thinking to himself, "Gee wiz, there has never been a gangster bumped off with a Tommy gun in all of Westmoreland County. Being a bootlegger here sure beats doing it in Chicago."
Obviously we don't know what Piazza was thinking at the time but while he was thinking whatever it was that he thought, a large touring sedan pulled into the station and parked next to him with the back window curtains closed. After it came to a stop the curtains parted and the muzzle of a Thompson machine-gun, said to be the first ever used in Westmoreland County, came forth. As the station attendant continued to pump petrol into Piazza's car,the gunman pumped a number of rounds into Piazza.
Mission completed, the sedan pulled away as Piazza slumped to the floor of his car. An ambulance was called and the bootlegger was rushed to the hospital where he died later in the day.
