Convicted gangster and multiple murderer James J. “Whitey” Bulger has been transferred again, this time to a high-security federal penitentiary in Tucson, according to the US Bureau of Prisons website.

Bulger, 84, is at the United States Penitentiary Tucson, where 1,552 inmates live in a high-security prison and 148 inmates are in an adjacent minimum-security satellite camp, the site says.

Bulger was held at the Plymouth County House of Correction after his capture in 2011, while he awaited trial. In August, after his conviction, he was moved to the Metropolitan Detention Center in Brooklyn, N.Y. The Globe reported in mid-December that he had been moved to a prison in Oklahoma.

Bulger was captured in June 2011 in Santa Monica, Calif., after more than 16 years on the run. The former South Boston crime boss was convicted after an eight-week trial of racketeering, extortion, money laundering and weapons charges. A jury in federal court in Boston found he participated in drug dealing and 11 of 19 murders he was accused of.

The gangster, who spent much of the trial trying to refute evidence that he was a long-time FBI informant, is appealing his conviction.

The Globe reports today that Bulger and Catherine Greig penned jailhouse loveletters on a legal pad ferried between prisons by a defense attorney.
