In March of 1990, two thieves posing as Boston police officers entered the Isabella Stewart Gardner Museum and stole thirteen works of art including masterpieces by Vermeer, Rembrandt, Edgar Degas, and Edouard Manet. Now known as the greatest art heist in history, the case has remained unresolved despite the countless hours of investigating the FBI has conducted. While the Bureau has offered immunity to anyone who assisted in the recovery of the artworks, they have never received a concrete lead.

While it would appear that the reputed organized crime figure, Robert V. Gentile, who found himself in federal court this Wednesday on drug trafficking and gun possession was irrelevant to the Gardner case, the FBI believed Gentile had vital information to share. Gentile, 76, of Manchester, Connecticut, helped federal authorities for 10 months prior to his arrest but none of the information was useful in tracking down the thieves. Gentile’s lawyer claims that his client did know some of the individuals the government believed were involved in the heist, but that most of them were dead by now. Gentile now faces a maximum of 150 years in prison if he is convicted. The government is willing to negotiate his sentence so that his prison term will be reduced to 46-57 months.

Gentile became involved in the Gardner case when Elene Guarente, the widow of Robert Guarente, a mob associated who died in 2005, told investigators that her husband gave Gentile a painting that he had kept in a tube since the 1990s.
