James “Whitey” Bulger was found dead in a federal prison Tuesday, NBC News reported. He was 89.
The Boston Globe reported that he was killed, but Bulger’s cause of death has not yet been confirmed by authorities.
The Boston organized crime boss was recently transported to high-security penitentiary USP Hazelton in West Virginia from a prison in Florida, where he spent the majority of his sentence.
Following a 2011 arrest, Bulger was given two life sentences in 2013 on 31 counts of racketeering and firearms possession, including 11 murders of which Bulger was convicted.
