 The mobster was serving time for murder, racketeering and extortion. | Mafia capo Frank "Bobo" Marrapese Jr., known as one of the most vicious enforcers for New England crime boss Raymond L.S. Patriarca, died in prison in 2017. |  |
 Raymond L.S. Patriarca | He operated the Acorn Social Club in the heart of Federal Hill, where he shot mob associate Richard "Dickie" Callei to death on March 15, 1975 and had the corpse buried near a golf course. It took nearly a decade to catch Marrapese for that murder. He continued to commit other crimes, such as a hijacking case involving La-Z-Boy recliners in the early 1980s. Marrapese was convicted of Callei's murder in 1987 and served 25 years. He was released on parole in 2008, but was among two dozen people arrested in a gambling ring in May 2011 and was sentenced in 2013 to nine years for racketeering and extortion. |  |
 | While Marrapese spent most of his life in prison, not all of his many charges stuck. He was acquitted in the murder of Anthony 'The Moron' Mirabella at Fidas Restaurant in May 1982, as well as the August 1982 murder of Ronald McElroy, who was beaten to death with a baseball bat. |  |
