At 1:24 a.m. on March 18, 1990, two men dressed as Boston police officers rang the intercom at the Isabella Stewart Gardner Museum and told the security guard they were responding to a disturbance call. The guard on duty, 23-year-old Rick Abath, broke protocol and let them in through the employee entrance. They told him to step away from the security desk—the only place in the building from which he could summon police. Then they handcuffed both guards to pipes in the basement and spent the next 81 minutes methodically looting the museum.
They sliced paintings from their frames. They took Rembrandt’s only seascape, The Storm on the Sea of Galilee. They took Vermeer’s The Concert, one of only 34 known paintings by Johannes Vermeer, now estimated to be the most valuable unrecovered painting on earth—worth roughly $250 million alone. They took two more Rembrandts, a Manet, a Flinck landscape, five Degas sketches, a Chinese bronze beaker from the Shang dynasty, and a Napoleonic eagle finial from the top of a flagpole. They left behind paintings worth more than what they took—a Titian and a Botticelli among others—which has puzzled investigators for decades and suggests they were either working from a list, operating under time pressure, or didn’t know the relative value of what they were looking at.
Thirteen works. Eighty-one minutes. The FBI initially estimated the value at $200 million, raised it to $500 million by 2000, and art dealers have suggested the true figure could exceed $600 million. It is the largest property crime in United States history. Thirty-five years later, no arrests have been made. No works have been recovered. The museum offers a $10 million reward—the largest bounty ever offered by a private institution—and the empty frames still hang on the walls.
Why the empty frames matter
Isabella Stewart Gardner’s will stipulated that the museum’s collection must remain exactly as she arranged it. If any object were permanently removed, the entire collection would pass to Harvard University. The museum interprets this as both a legal obligation and a moral one: the empty frames remain hanging in the Dutch Room and Short Gallery as placeholders—what the museum calls “symbols of hope awaiting their return.” Visitors walk through galleries where gold frames hold nothing, the absence of each painting as present as any object in the collection.
The museum completed a major renovation of the Dutch Room in 2024—the gallery from which six key works were stolen, including the Rembrandts and the Vermeer. The renovation, projected to conclude by late 2026, involves deep cleaning the terracotta floors and treating the walls. The empty frames stayed up throughout.
What the FBI thinks happened
Geoffrey Kelly, the FBI agent who led the Gardner investigation for 22 years, gave his first in-depth interview after retiring in 2024. On the 35th anniversary of the theft in March 2025, Kelly identified—by name, for the first time—the two men he believes were the thieves: George Reissfelder, a petty thief, and Leonard DiMuzio, an associate implicated in home invasions. Kelly’s theory is that mob associate Carmello Merlino, who ran an auto repair shop in Boston’s Dorchester neighborhood, sent them into the museum.
Kelly believes the initial plan was to make quick money stealing the Rembrandts. “Then they wake up on March 19 to realize that they’ve committed the heist of the century,” he told the Boston Globe. The problem with committing the heist of the century is that you can’t sell the proceeds. A Vermeer is not fungible. There is no buyer who can display it without attracting the attention of every law enforcement agency on earth. The art became simultaneously the most valuable and the most unsellable property in criminal history.
What happened next is where the case turns from a heist story into a murder story. Reissfelder was found dead of an intravenous cocaine overdose in March 1991—a death Kelly considers suspicious. Two weeks later, DiMuzio disappeared; his body was found in the trunk of a car in East Boston. James Marks, a mob associate who boasted he had access to some of the paintings, was shot to death outside his Lynn home in February 1991. Robert Donati, implicated in the heist by multiple sources, was stabbed to death outside his Revere home seven months later. Four men linked to the stolen artwork, dead within 18 months of the theft. Kelly said the deaths had “a chilling effect” on the investigation. The people who might have talked were in the ground, and the people who replaced them in the chain of possession had every incentive to say nothing.
The FBI believes the artwork moved through several locations over the decades—up to Maine, down to Connecticut, and possibly to the mid-Atlantic states. “We’re pretty confident about that,” Kelly said, immediately followed by: “I always temper that by saying that we could be wrong.” The bureau has conducted sting operations, interrogations, and undercover operations for 35 years. Merlino was arrested in a 1999 sting operation and convicted of attempting to rob an armored car depot, but the Gardner paintings were never recovered from him or his associates.
Why stolen art almost never gets sold
The Gardner theft illustrates a broader truth about high-value art crime: the theft is the easy part. The stolen art market is not a functioning market. There’s no Craigslist for Vermeers. The pool of potential buyers for a painting worth $250 million is vanishingly small, and every person in that pool knows the work is stolen and that purchasing it constitutes a federal crime. The art world is a community where provenance—documented ownership history—determines legitimacy, and a painting with no provenance is a painting that can never be displayed, loaned, exhibited, or resold through legitimate channels.
Stolen masterworks typically follow one of three trajectories. Some are ransomed back to the institution or the insurance company—the thieves negotiate a finder’s fee in exchange for the return, essentially selling the art back to the people they stole it from. Some are used as collateral in criminal enterprises—a Rembrandt in a warehouse serves as a form of underworld currency, backing drug deals or serving as a negotiating chip for reduced sentences. And some simply disappear into private collections—wealthy individuals who want to own a Vermeer and don’t care that no one can ever see it. The FBI believes some or all of the Gardner works may have been used in this way, passed between criminal networks as a form of untraceable, ultra-high-value collateral.
The museum’s chief of security, Anthony Amore, has said that thinking about the theft in terms of dollar value misses the point. “We’re talking about the only seascape that Rembrandt ever painted. You can’t put a price tag on that.” The Concert is one of only 34 Vermeers in existence. The loss isn’t financial. It’s cultural—irreplaceable works that belong to the public record of human artistic achievement, locked in a basement or attic or safety deposit box by someone who either can’t sell them or doesn’t want to.
The guard who died with the secret
Rick Abath, the guard who let the thieves in, maintained his innocence until his death in February 2024 at age 57 in Brattleboro, Vermont. He passed polygraph tests. His physical restraints in the basement were consistent with his account. The FBI agent who oversaw the early investigation concluded that the guards were “too incompetent and foolish” to have committed the crime. But in 2015, the FBI released security footage from the night before the theft showing Abath admitting an unidentified man into the museum for a conversation at the security desk—a visit Abath said he couldn’t recall and couldn’t explain.
Kelly, who spent 22 years on the case, told the Globe he believes Abath was involved. Abath lived quietly in Vermont after leaving the museum, dealing with death threats and employment difficulties for the rest of his life. He spoke occasionally to journalists. He never changed his story. He took whatever he knew—whether that was complicity, negligence, or genuine ignorance—with him.
Why it stays unsolved
The Gardner case has everything a heist investigation needs except evidence. The museum had no interior cameras in 1990—the board considered the cost prohibitive. The only way to summon police was from the security desk that the thieves made the guard step away from before the handcuffs went on. There were 60 motion detectors, but the thieves had already been let inside by the guard. The physical evidence is thin. The witnesses are dead—the suspects, the mob associates, and now the guard who opened the door.
The FBI and the museum both describe the same hope: that getting one piece back will create a snowball effect. If one painting surfaces, and the person who has it receives the reward and isn’t prosecuted, the logic goes, others will follow. The incentive structure is designed to make cooperation more attractive than silence. After 35 years, the silence holds.
The empty frames on the walls of the Gardner Museum are, depending on how you look at them, either the most depressing or the most optimistic things in any museum in the world. They’re depressing because they represent the permanent absence of irreplaceable works that the public will likely never see again. They’re optimistic because the museum refuses to fill them—refuses to accept that the art is gone, refuses to replace what was taken, refuses to move on. The frames are an institutional act of faith that the paintings will come back, maintained for 35 years against all available evidence, in a building whose founder required that nothing ever change.
