Federal law enforcement officials released information today indicating that the thieves linked to the Isabella Stewart Gardner Museum heist may have been identified (curiously, however, the thieves identities have not been disclosed).  In 1990 thirteen masterworks of art, including works by Rembrandt, Vermeer, Degas, Manet, and Renoir valued at approximately $500 million, were stolen from the Boston museum.  Vacant frames which remain on the museum walls remind visitors to the museum of the infamous heist.  Unfortunately, although the thieves may have been identified, the artwork is still at large and law enforcement is asking for the public to provide any information to help with the recovery
