Bompensiero had numerous dealings in Las Vegas with Cleveland mobster and casino owner Moe Dalitz and Chicago Outfit mobster Anthony Spilotro. He also counted retired Bonanno crime family boss Joseph Bonanno in Arizona, and John Roselli as allies.
In the early 1970s, Bompensiero and Tony Spilotro started a large loan sharking operation in Las Vegas. In November 1975, acting as driver, Bompensiero helped Spilotro murder Tamara Rand, a multi millionaire real estate broker and investor from San Diego.
Frank Bompensiero was shot to death at close range with a silenced .22 caliber handgun while walking home after using a pay phone outside an Arco Station in the Pacific Beach neighborhood of San Diego. In 1978, Fratianno told law enforcement that mob associate Thomas Ricciardi had killed Bompensiero in return for membership in the Los Angeles family. When Ricciardi shot Bompensiero, Jack LoCicero was waiting in the getaway car. The government later charged Ricciardi with Bompensiero's murder, but he died of heart disease before the trial could start. The rest of the defendants were acquitted of murder at the trial, but were convicted of racketeering.
