By KRISTA LARSON The Associated Press RUTLAND A single gunman robbed an armored car company early Thursday of about $1.9 million, believed to be the largest robbery in Vermont history, officials said. The gunman tied up two guards at the Rutland offices of Berkshire Armored Car Services Inc. between 5:30 and 6:30 a.m., Jerry Reder, the owner of the company, said from the Pittsfield, Mass., headquarters. There were no injuries, thank God, Reder said. There may have been a driver waiting for the robber in a car outside the building, officials said. The Berkshire Armored Car office is in a two-story brick building in an industrial area of Rutland just south of downtown. On Thursday afternoon three armored vehicles were parked in front. There was nothing to indicate a robbery had taken place there earlier in the day. We're just shocked it was that much money, said Josh Perkins who works at the nearby Sastenal Co. Sue Emery, who works in Mr. G's Liquidation Center, up the street from Berkshire, said that when she showed up for work Thursday she saw police in front of the building. At first she thought it was just an accident. After learning of the heist, her first thought was whether anyone was hurt. I was worried about people I knew. My other thought was: God, that's close. John Kavanagh, the FBI agent in charge in Vermont, said the investigation was continuing. We are still in the process of conducting interviews, Kavanagh said. We don't want to put out an inaccurate description. He also declined to offer a description of the suspected getaway vehicle. I'd rather wait on the suspected vehicle at this point until we get all the facts together, Kavanagh said. Reder said insurance investigators were working with the the FBI and local police. There are a lot of agents there, Reder said. Reder estimated the loss at $1.9 million, although a full accounting had not been completed. Reder said he did not know how many people were in the building at the time of the robbery. Company officials also said they don't know how a robber could have gotten into the building. It's too early to tell. That would be a vital clue, Reder said. Berkshire operates throughout New England. There have been a number of armored car robberies in New England over the last decade. Among them: - In 1997 thieves took $1.5 million from a Berkshire armored car terminal in West Springfield, Mass. A former guard was sentenced to 18 months in jail for his role in the theft. - In 1996 there were four armored car robberies in Massachusetts, including one in which a guard was killed. In 1994, two guards were killed when an armored car was robbed in Hudson, N.H. It is believed that the largest robbery ever to occur in Vermont was in St. Albans in 1996 when robbers broke into the Franklin Lamoille Bank and made off with an estimated $250,000.
