FBI's second most wanted man has passed away, reported ABC.
James "Whitey" Bulger, the notorious Boston mob boss who was second only to Osama Bin Laden on the FBI's Most Wanted List, died Tuesday.
He was found unresponsive at a Hazleton federal prison in Bruceton Mills, West Virginia. Authorities say they performed life-saving measures on the 89-year-old after he was found at 8:20 a.m.
There was no immediate word on the cause of death. A statement from the U.S. Department of Justice noted that "no staff or other inmates were injured, and at no time was the public in danger."
According to the Boston Globe, a fellow inmate with mafia ties is being investigated for his murder.
Bulger died a day after he was transferred to the Hazelton prison. Bulger was convicted in 2013 of murdering 11 people, as well as extortion, money laundering, and weapons charges.
His 2013 trial came nearly 20 years after he went on the run after being tipped off to a pending federal indictment. The warning came from a corrupt FBI agent.
He spent 16 years on the lam and was arrested in 2011 in Santa Monica, California. At his trial, he was sentenced to life for his crimes.
