The owner of a New Hampshire gun powder plant where an explosion killed two workers is going on trial for manslaughter and negligent homicide.
County prosecutors say 64-year-old Craig Sanborn, of Maidstone, Vt., was reckless in the production, testing and storage of explosive black powder and failed to train and provide safeguards for employees.
He has pleaded not guilty. His lawyer says he can't be held accountable for the blast that happened while he was at a gun show in North Carolina.
Killed in the explosion at the Black Mag plant in Colebrook in May 2010 were 56-year-old Donald Kendall, of Colebrook, and 49-year-old Jesse Kennett, of Stratford. Both had started working at the plant a month earlier.
