Francis Patrick Salemme (August 18, 1933 – December 13, 2022), sometimes spelled Salemmi, also known as "Cadillac Frank" and "Julian Daniel Selig", was an American mobster from Boston, Massachusetts who became a hitman and eventually the boss of the Patriarca crime family of New England before turning government witness.

He started working with Morelli in criminal activities after getting out of prison, and he quickly gained stature in the Patriarca family as an associate – although he could not become a made man or full member.

It was later established in testimony by several witnesses and confirmed by the U.S. House of Representatives Organized Crime unit investigation that Salemme was involved in the bombing, but did not carry it out.

During the trial of retired FBI agent John Connolly, Salemme denied murdering a nightclub owner named Steven DiSarro in 1994.

In previous years, Salemme had forged strong ties to Whitey Bulger and the mostly Irish American Winter Hill Gang.

The feud between Salemme and Russo continued until John Gotti, the boss of the New York Gambino crime family, brokered a peace agreement.

At the end of the operation, Frank, Sr. was arrested in Fort Lauderdale, Florida and charged with racketeering, crossing state lines for criminal activity, extortion, conspiracy, and loansharking.

In 2008, he was sentenced to five years in prison after pleading guilty to charges of obstruction of justice and making false statements for lying to federal authorities investigating the disappearance of 43-year-old Steven A. DiSarro, who went missing in 1993.

[5][6] Judge Allison D. Burroughs sentenced Salemme and former Patriarca crime family associate and accomplice, Paul Weadick, to life in prison on September 13, 2018.

[7] According to former Winter Hill Gang member and Whitey Bulger associate, Stephen Flemmi, Salemme stood by and watched as his son strangled DiSarro while Weadick held his legs.
