Chicago Outfit mobster Frank "Frankie Breeze" Calabrese Sr. died on Christmas Day at the age of 75 while serving a life sentence at the federal facility in Butner, NC as reported by Bridget Doyle for the Chicago Tribune:
[Federal prosecutor T. Markus] Funk said Wednesday that those hurt by Calabrese's criminal actions would likely find it hard "to muster much regret" over his death behind bars. "Calabrese reigned as one of the nation's most prolific and feared mob killers, only to die alone and far from home on Christmas Day," Funk wrote in an email Wednesday. "Whether this qualifies as poetic justice, or the sad final chapter of a largely squandered existence, is for others to decide."
Calabrese was convicted on racketeering charges involving multiple murders in the 2007 Family Secrets trial after his son Frank Jr. became a wired cooperator for the feds, and in commenting on the old man's death the mob scion said "I am comfortable with the fact that he's not suffering in there anymore and that no one else has to suffer on the street."
In all Calabrese was convicted of thirteen murders spanning from 1970 through 1986 at his 2007 racketeering trial, and each of them is recounted in grisly detail by Mitch Dudek for the Chicago Sun-Times.
Frank Jr. is bringing the family's story to the silver screen based on the "best-selling book about his decision to abandon the mob lifestyle and go against his father" as reported by Dane Placko for My Fox Chicago:
"What I was concerned with is not just somebody that wants to make the next shoot 'em up gangster movie. This is about family. This is about the dark side of crime," he said.
