A notorious Boston mobster resurfaced in Tennessee and made claims about the infamous 1990 heist at the Isabella Stewart Gardner Museum.
Robert Luisi Jr. says years back, Robert Guarante told him the paintings stolen from the museum are buried at a home in Florida, the Boston Globe reports.
Guarente, who is now deceased, reportedly said the paintings were buried under a concrete floor.
The exact location is unknown.
Maine State Police records show Guarente listed a lakeside house in Orlando as his residence in the early 1990s. That structure was torn down in 2007.
The 13 stolen paintings are worth an estimated $500 million.
