The notorious Boston mobster James "Whitey" Bulger has been killed in prison. Bulger was recently transferred to a West Virginia prison and was found dead today.

According to WHDH in Boston, the 89-year-old was discovered dead inside the U.S. Penitentiary Hazelton, which is a high-security prison. But, it has an adjacent minimum-secuity satellite camp on Bruceton Mills, West Virginia.

Initial reports say Bulger was reportedly killed around 8am this morning in general population.

Bulger, who had been one of the FBI's most wanted fugitives for sixteen years was finally caught back in 2011. He and his longtime companion, Catherine Greig were found living in Santa Monica, California and taken into custody.

Bulger's 2013 trial ended with him being convicted of numerous crimes including, participating in eleven murders. He was serving a life sentence.

Prison officials and Bulger's attorney declined to comment as to why he was recently moved from a jail in Florida to a transfer facility in Oklahoma City and eventually to West Virginia.
