Amherst College in Massachusetts and the FBI are reopening the investigation into a theft from the campus art museum that took place nearly 40 years ago. In February 1975, three centuries-old paintings worth more than $400,000 were stolen from the college’s Mead Art Museum. Two of the paintings were recovered in 1989 following a federal sting operation in Illinois, but “Interior with Figures Smoking and Drinking” by the Dutch artist Jan Baptist Lambrechts was never found.

Since joining the Mead in 2006, the museum’s head of security, Heath Cummings, has been examining museum files, college archives and old newspaper stories as well as speaking with various art experts and law enforcement agents. Cummings brought his information to the FBI, hoping that the agency would agree to take a fresh look at the case.

The FBI is hoping that the renewed search will generate new leads and tips from the public.
