Whitey Bulger files notice that he will appeal convictions that sent him to prison for life

James J. “Whitey” Bulger’s lawyers notified a federal court in Boston today that the notorious former South Boston crime boss will appeal the racketeering conviction that sent him to prison for life.

The defense filed the “notice of appeal” after US District Judge Denise J. Casper entered the judgment on the case docket.

In August, a jury convicted Bulger, 84, of participating in 11 murders, drug trafficking, extortion, money laundering and other crimes while running a sprawling criminal enterprise from the 1970s through the 1990s.

Last week Casper sentenced him sentenced to two consecutive life prison terms.

Bulger claimed he did not get a fair trial because the judge refused to allow him to present a so-called immunity defense. Bulger claimed former federal prosecutor Jeremiah T. O’Sullivan, who died in 2009, promised him immunity for all of his crimes, including murder, decades ago.

Casper ruled that Bulger provided no evidence to support his claim prior to trial, and that even if he had, O’Sullivan wasn’t authorized to grant such immunity.

Bulger will remain at the Plymouth County Corrrectional Facility until the US Bureau of Prisons assigns him to a federal prison. He’s been held at the jail since he was captured in June 2011 in Santa Monica, Calif., after more than 16 years on the run.
