It seems Robert “Bobby the Cook” Gentile can’t catch a break. The 79-year-old mobster, who has been touted as the Federal Bureau of Investigation’s best hope for finding out what happened to $500 million worth of stolen art, says the agency has twice entrapped him, sending informants to induce him to commit crimes so that they can offer leniency in exchange for information on the missing work.

The art theft, the largest in American history, went down in 1990 and involved a Rembrant, a Vermeer and more which were taken from Boston’s Isabella Stewart Gardner Museum.
