In 1990 now-deceased Boston mobster Robert Guarente masterminded an art heist from the Isabella Stewart Gardner Museum which made off with masterworks including by Rembrandt, Vermeer, Degas and Manet worth $500 million.
Twenty-five years later the paintings still are missing, and the feds still are in a pissing match with Robert Gentile whom they suspect has some knowledge over their whereabouts notwithstanding his denials as reported by Edmund H. Mahony for the Hartford Courant: "people with knowledge of the investigation have said that, in March 2010 -- a month before the FBI directed its informant to talk to Gentile -- Guarente's widow told the FBI and the museum's security director that she saw her husband hand Gentile two of the stolen Gardner paintings outside a restaurant in Portland, Maine, sometime between 2002 and Guarente's death in 2004."
Meanwhile, the FBI last week released previously overlooked -- whoops! -- surveillance video which "shows a security guard admitting an unidentified man into the Isabella Stewart Gardner Museum the night before the infamous 1990 art heist" as reported by Milton J. Valencia for The Boston Globe: "law enforcement officials are now questioning whether the suspicious actions constituted a dry run for the heist, and it refocuses the spotlight on Richard Abath, the rock musician moonlighting as a security guard who fell under the suspicion of authorities soon after the robbery." Two Boston-area antiques dealers have advised law enforcement after seeing the surveillance video that they believe the mystery figure is someone in the antiques trade currently residing in Florida who "likes to brag about his relationship to a pair of notorious Boston art thieves" as reported by Susan Zalkind for The Daily Beast.
