Federal law enforcement officials believe Boston gangster James “Whitey” Bulger was killed with a “lock-in-the-sock” in a grisly assault inside his prison cell, multiple law enforcement officials briefed on the case told NBC News.
Bulger, 89, was struck repeatedly when several inmates attacked him on the morning after he arrived at Hazelton federal penitentiary in West Virginia, two sources said Wednesday.
The weapon that is believed to have been used to kill Bulger, a longtime FBI informant, involves a lock placed inside a sock and wielded like a mace.
Officials told NBC News that federal investigators are eyeing several potential suspects in the Tuesday killing, including a reputed New England mafia hitman.
