Frank "the Bomp" Bompensiero
"The Bomp" was the most feared hit man of his era. His specialty was murdering fellow mobsters. He got away with being an informant for 10 years until the FBI hung him out to dry. He would die the same way he had lived.

Before turning FBI informant in 1967, Frank "the Bomp" Bompensiero had been the most feared Mafia hit man in Southern California for more than 30 years. Killing fellow mobsters was his specialty. His reward from the Los Angeles Mafia was to be made boss of San Diego. When his long-time friend Jimmy "The Weasel" Fratianno found out in 1976 that the Bomp had turned informant, it took the Mafia more than six months to get the hit on Bompensiero executed. Later, after Fratianno had transformed himself into a media event by becoming an FBI informant himself, he said during a television documentary in 1991 that Bompensiero "had buried more bones than could be found in the brontosaurus room of the Museum of Natural History."
Bompensiero was born in Milwaukee in 1905. Not much is known about his early years. The first murders he was involved in for the mob turned out to be "messy" ones. In California during 1937, newly arrived Benjamin "Bugsy" Siegel laid down the law and stated that all West Coast gamblers would have to share their profits 50-50 with him. The lone dissenter was Lew Brunemann, a gambler from Redondo Beach who had aspirations of controlling all the gambling in southern California.
