This blog has covered elsewhere the allegations concerning the largest unresolved art theft of all time — the 1990 theft at the Isabella Stewart Gardner Museum in Boston in which paintings and drawings worth more than $300 million were taken.
Now, on the 20th anniversary of the theft, the New York Times reports that the F.B.I. has resubmitted DNA samples recovered in the case for updated testing, and a longstanding $5 million reward offered by the museum is being publicized anew, with the use of two interstate highway billboards to advertise it. The Times also reports that the statute of limitations for prosecuting the thieves — two men who masqueraded as Boston police officers — has long since passed, and federal officials have held out the possibility of immunity, in exchange for information, for anyone subsequently involved in the theft.
