Thirty-four years ago today, one of the most infamous heists in museum history unfolded at the Isabella Stewart Gardner Museum in Boston. A group of thieves disguised as Boston police officers stole 13 works — some painted by masters including Rembrandt, Degas and Vermeer — estimated to be worth at least half a billion dollars.

The mystery remains unsolved. And at the museum, one man is still investigating.

“We know a heck of a lot of what happened” on March 18, 1990, said Anthony Amore, director of security and chief investigator at the Gardner Museum. “Two thieves disguised themselves as police officers and used a ruse to enter the building, and subdued the guards and spent the next 81 minutes taking some of the world's greatest masterworks.”

But the masterworks have never been recovered, despite far-reaching efforts and a $10 million reward for any information that leads to the safe return of the paintings.

“No museum in the world has ever done what the Gardner has done, which is launch its own unceasing effort to recover the works, alongside the FBI,” Amore said.

The museum gets plenty of tips, he said, and investigators also source out their own leads.

“As you can see, it's a long process. And it's not unusual in the annals of art heist for masterpieces to be gone this long before being recovered,” he said.

Amore said the paintings could still be close to home.

“There's no place in the world that someone hasn't said our paintings currently are, but when you look at the history of art crime in America, the paintings don't travel far from the place where they're stolen,” he said. “We did get some information that they may have been shopped in Philadelphia at one point, years ago, but we don't have any information whether any of them were sold there.”

Amore said he believes the artworks were likely stolen for money.

“What happens is the next day the thieves see that they're far too valuable and highly recognizable to traffic,” Amore said. “They hide them, and often they will hold them in case they can use them for some sort of negotiating, advantage with police or prosecutors, as we saw in 1975 when Miles Connor stole a Rembrandt from the MFA and used it to negotiate a smaller sentence.”

Today, he said, the Gardner Museum will mostly proceed with the day as usual.

“We don't focus on the somber nature of it,” he said. “Yes, I speak to Anne Hawley, who was the director at the time. Yes, our current director, Peggy Fogelman, will come in and we'll talk about it a bit. But we focus on the work. And when I'm done speaking to you, I will continue investigating today with that mission in mind: Bringing the paintings back so the public can enjoy them.”

The lore around the heist might increase interest in the museum, he said, but the museum is quite busy even without those visitors.

“We're bustling. And the museum has never been better-attended,” he said. “I would say this about people coming to see the empty frames, though. That does happen. Those same people, when they leave, they're talking about something else, because the museum is vibrant and it's filled with beautiful art and horticulture, and there's so much to see here that it's really an unbelievable experience, empty frames or not.”
