The thieves allegedly behind one of the most brazen art thefts in American history, perpetrated 25 years ago on Boston’s Isabella Stewart Gardner Museum, have been revealed as two members of a local organized crime syndicate. The controversial right-wing website Breitbart News first reported their names Sunday as George Reissfelder, then 49, and Lenny DiMuzio, then 42, citing sources within the Federal Bureau of Investigation. The Breitbart story appears to follow-up on a segment produced by WCVB TV of Boston, which states that the FBI has known the suspects’ names for some time, but has not released them publicly.

Both suspects died within a year of their purported March 18, 1990 break-in at the museum, frustrating investigators who have searched in vain for the 13 works since — including drawings and paintings by Vermeer, Rembrandt, Degas, and others, worth some $500 million today.
