On the night of March 18, 1990, the largest art heist in history occurred at the Isabella Steward Gardner Museum in Boston, when $500 million worth of artwork was stolen, including paintings by Vermeer, Rembrandt and Manet, as well as drawings by Degas and a Chinese bronze vessel from the 12th century BC.

The spectacular robbery attracted much media attention and has been covered in numerous publications and documentaries. The museum itself has offered a $10 million reward for information leading to the investigation. However, the case remains cold and none of the works of art have reappeared.
However, leads have led investigators into the mafia community in and around Boston because two gangsters Bobby Guarente (†2004) and Robert Gentile (†2021), considered the main suspects, were said to have tried to sell the works on the black market in 2002. But there is one other person whose fate may be linked to the incident, as Bob Ward has now reported in Boston 25 News 'New England Unsolved' series: Jimmy Marks.

Jimmy Marks was shot dead outside his home in Lynn near Boston on February 10, 1991, eleven months after the art heist at the Isabella Stewart Gardener Museum. Marks died by two shots to the back of the head, a tactic reminiscent of a mafia-style execution.
Jimmy Marks was a career criminal who served time in prison for bank robberies in the 1960s and was closely associated with Bobby Guarente. As early as 2010, Guarante's widow Elene testified to the FBI that her deceased husband gave two of the stolen paintings to Gentile and also killed Marks. However, this could never be proven and the murder of Marks has remained just as unsolved as the art heist in Boston.

But now investigators have been tipped off that Jimmy Marks had bragged about hiding some of the paintings from the art robbery before he died. Was Mark's downfall due to his careless behavior that led the thieves to get him out of the way?
In fact, investigators have suspected the two crimes are connected for a decade, although searches of Jimmy Mark's home have never turned up the slightest clue. The new information, however, shows that the lead towards the Mafia, with Guarente and Gentile at its core, is still a hot one.
