The FBI has ended its investigation into the biggest heist in Vermont history – the $1.9 million theft from an armored car company in Rutland, AP reports.

A single man with a gun overpowered two guards at Berkshire Armored Car in Rutland 11 years ago Thursday, and despite the investigation by the FBI and Rutland police, the case has never been solved.

According to reports, the FBI posted information under the “seeking information” section of its website for years. Now, the statue of limitations for the crimes has past, so the FBI says the case is closed.

AP reports that the gunman handcuffed and tied both guards before taking backs of money and making a getaway in a dark van.
