Sources are currently split as to whether or not accused murderer and ganglord James ‘Whitey’ Bulger should be called to testify about what he may know in connection to the infamous Isabella Stewart Gardner Museum heist. The 20-year-old robbery saw $500 million worth of art robbed from a Fenway gallery.

The Boston Herald reports on the contrasting opinions about Whitey Bulger’s possible involvement with the heist.

One of Whitey Bulger’s associates, who is “sure” that Whitey knows something about the robbery, said to the Boston Herald that “It may have been the one thing he held back as an ace in the hole. He loved art. He’s probably even seen the (expletive).”

However, Christina DiIorio-Sterling, spokeswoman for the U.S. Attorney’s Office in Boston, told the Boston Herald that, “As we have said in the past, the government has no reason to believe that James Bulger was involved in the Isabella Stewart Gardner Museum theft.”

Whitey Bulger, who was famously captured in California last summer after being on the FBI’s Most Wanted list for 16 years, is set to begin trial for 19 murders in November.

A former Bulger investigator predicted to the Boston Herald that out of respect for those deceased, prosecutors will make no attempts to negotiate with the mobster, no matter how much information they believe he can provide.

“He’d have to know the names of the guys who nailed Christ to the Cross,” the former investigator said.

Ulrich Boser, author of ‘The Gardner Heist: The True Story of the World’s Largest Unsolved Art Theft,’ does not believe Bulger knows where the paintings are but would be interested to pick his brain anyway implying that Bulger probably has some privy information to the heist.

“I do think that when he [Bulger] walked out of his apartment the morning after the theft and saw the headlines he made some phone calls,” said Boser.
