Philip Testa was an Italian–American mafia boss who led the infamous Philadelphia crime family of the U.S. from 1980 till his murder in 1981. It is believed Philip was born in Sicily and later moved to the U.S. with his parents. However, some believe he was born in Philadelphia. Philip was initially a gambler and owned a construction business. He joined mobster and Philadelphia crime family leader Angelo Bruno’s gang as his underboss in 1970. After Angelo’s death in 1980, Philip took over the leadership of the gang. However, owing to differences within the gang, he was murdered on his own porch in 1981. Apparently, the murder had been conspired by Philip’s own underboss, Peter Casella, and Frank Narducci Sr. Thus, one of their men, denotated a nail bomb at Philip’s home. Following Philip’s death, a huge mafia war ensured for the control of the gang. Nicodemo Scarfo became the new boss of the crime family and made Philip’s son, Salvatore, his caporegime. Eventually, Salvatore was murdered on the orders of Scarfo.
