Decades after the Gardner heist, police focus on guard

Night watchman Richard Abath may have made the most costly mistake in art history shortly after midnight on March 18, 1990. Police found him handcuffed and duct-taped in the basement of the Isabella Stewart Gardner Museum seven hours after he unwisely opened the thick oak door to two thieves who then stole 13 works of art valued at more than $500 million.

For years, investigators discounted the hapless Abath’s role in the unsolved crime, figuring his excessive drinking and pot smoking contributed to his disastrous decision to let in the robbers, who were dressed as police officers. Even if the duo had been real cops, watchmen weren’t supposed to admit anyone who showed up uninvited at 1:24 a.m.
