For the past seven years, Amore has also served as the museum’s chief investigator into the 1990 theft of 13 priceless works of art from the museum. 

Author of “Stealing Rembrandts: The Untold Stories of Notorious Art Heists” with investigative reporter Tom Mashberg, Amore discussed some of the most infamous art heists of the 20th century, involving works valued $1 billion in total. 

Chief among the heists involved one at the at the Isabella Stewart Gardner Museum, which alone resulted in the loss of $500 million worth in paintings, etching and other works that have yet to be recovered. 

In that case, two men posing as Boston police officers were buzzed into the museum on March 18, 1990, after saying they were responding to a disturbance. They handcuffed the two night guards who were on duty and took them into the basement, where they were secured to pipes and their hands, feet and heads were duct taped. 

Amore described how the thieves made off with priceless works like Rembrandt’s Storm on the Sea of Galilee, A Lady and Gentleman in Black and a Self Portrait, Vermeer’s The Concert and Edouard Manet’s Chez Tortoni, according to the museum’s website. 

Not all art thieves, however, were so clever. Amore also regaled the audience with stories of robbers with more bravado than brains — among them Myles Connor, a notorious Boston art thief who unwittingly tried to sell works by Andrew Wyeth and NC Wyeth to an undercover FBI agent. He and several accomplices stole the paintings — along with several other famous paintings — from the Woolworth Estate in Monmouth, Maine, in the early 1970s. 

“When you steal these highly recognizable paintings, there’s no market for them. There’s no one out there who’s going to buy a painting that everyone knows is stolen. Especially when, even if you’re paying pennies on the dollar, you’re paying millions of dollars. It doesn’t take a genius to figure out that people don’t spend lots of money on things they can never show anyone. 

“Myles found that out, he couldn’t find a buyer for these Wyeth paintings,” Amore said. “He looked and looked and looked and couldn’t find one. Then all of a sudden, he gets lucky and he comes across a guy named Bernie Murphy who wants to buy these paintings from him.” 

Murphy arranged to meet Connor in the parking lot of a Cape Cod IGA store to discuss a deal. 

“Myles is elated,” Amore said. “They go, they park next to each other, Myles opens his trunk and shows him the Wyeth paintings.” Unfortunately for Connor, the supposed buyer reaches into his pocket and pulls out his FBI badge.

Since crowd-sourcing was the goal, the FBI should be pleased. But we didn't really learn anything new beyond the assertion that some of the stolen paintings made their way to Philadelphia a decade ago. I was invited to speak with investigators alone for a few minutes after the news conference. They are dedicated men to be sure, and they were candid: they told me that for now the train has "gone cold."

 It was attention grabbing to hear them say they know the identities of the thieves. (Keeping the names secret is wise from an investigative standpoint -- imagine the media swarm.) But any careful follower of the case can boil the list of likely robbers down to three men -- all Boston-area felons. My belief is that two of the thieves are dead, and the third is in prison. The dead men will tell no tales, but there is still a chance to squeeze the guy behind bars.

A lot of these characters, chief among them a gangster named Carmello Merlino, also deceased, can be heard yapping on wiretaps about their plans to return the art for the $5 million reward money -- if only they could find it. It's the gang that couldn't steal straight.

In just 15 minutes, they tied up an unarmed night watchman and a museum guide and, standing on antique furniture, lifted the paintings off the walls. One of the four works taken in the January theft was attributed to Rubens, another to Rembrandt.

Although over the last two decades or so other artists have overwhelmed his once vaunted prices, Rembrandt remains an iconic figure. Certainly, he is well known to thieves who were unable to resist gunning for works stored in galleries with negligible defense against robbery. Rembrandt’s 1632 portrait of Jacob de Gheyn III has the dubious honor of being the “most oft-stolen painting in the world”. As an International Herald Tribune headline once declared (with uncharacteristic wit), “Rembrandt Needed a Night Watchman.”

Authors Amore and Mashberg — the former the head of security at the Isabella Stewart Gardner Museum and the latter an award-wining investigative reporter — explain how media hype of record prices can attract the attention of thieves. They cite the Goldschmidt sale at Sotheby’s in 1958 as the “triggering event” for high art prices that led to criminal interest in art. Three years later Rembrandt’s Aristotle Contemplating the Bust of Homer became, at $2.3 million, the then most expensive painting ever sold. Doubtless, potential raiders noticed this.

 "One of the more intriguing characteristics of the Gardner heist is that two of the stolen paintings, "The Storm on the Sea of Galilee" (1633) and "A Lady and Gentleman in Black" (1633), both by Rembrandt, were cut from their frames."

"Were they so unschooled as to imagine they could manhandle the canvases without wreaking destruction on the paintings? That alone is a key insight into the culprits. Thieves schooled in art would have done no such thing. Moreover, the robbers anticipated that they were going to cut some paintings from their frames. Why else would they have brought along an instrument that was sharp and sturdy enough to slice through stiff, varnished paint and linen canvas? Two other major art thefts in Massachusetts (both involving Rembrandts, as the following chapters will show) were pulled off more than 15 years before the Gardner crime without anyone resorting to cutting canvases. Why do so now? Had these thieves learned their lessons in theft outside Massachusetts? Was this their first art crime?"

Anthony Amore: I reached out to Al years ago to have a conversation about art theft. He still lives in Massachusetts and we know many of the same people so it was an interesting conversation. Al has been on the hunt for the stolen Gardner art for many years and can speak more knowledgably about the crime figures who do not have the art than he can about who does. Despite his criminal history and proclivity towards taking paintings that don’t belong to him, we’re friends and I quite enjoy talking to him.

Anthony Amore: Myles and Al share a unique characteristic that sets them apart from virtually all other art thieves, and that is that both of them appreciate fine art and are knowledgeable on the subject. While this sounds admirable, in many respects it makes their crimes all the more worse, since they have a better understanding of the cost to society than a common criminal. And make no mistake: though they art aficionados, they stole art strictly for profit, not to enjoy it.

Anthony Amore: I believe that Carl saw an opportunity to get his story out but also to let the world know that he has turned his life around and is now a legitimate businessman. I see Carl as an exception to the rule that people never change. He seems to have made an earnest attempt to go straight.

Amore: Absolutely. I’ve felt that I have a clear picture of the sort of criminal who pulled off the Gardner heist.

Anthony Amore: I have the utmost respect for Charley Hill. His career is amazing, and, aside from being a wonderful guy, he is among the greatest art recovery agents in history. However (and Charley knows I feel this way), I do not share his belief regarding the IRA. I share the opinion of the Assistant US Attorney Brian Kelly that Bulger was not involved in the theft and has no information about it to share. We’re fortunate at the Gardner to have AUSA Kelly as the lead prosecutor for our case, as he is also the lead prosecutor in the Bulger case. He has put away all of Bulger’s cohorts, all of whom admitted to dozens of murders and other heinous crimes and have described all of Bulger’s exploits for juries and book readers alike. One would have to suspend an enormous amount of disbelief to think they wouldn’t admit to even the slightest knowledge about the Gardner theft. Add that to the fact that there’s not even the slightest bit of evidence pointing to an Irish connection, and I put that possibility very low on the list of likelihoods. Of course, all that being said, the paintings are still missing, so we cannot rule anything out. And if a person from Ireland shows up at our door with the art this afternoon, I’ll be very glad to admit that I was wrong!
