A former gunpowder plant owner imprisoned over a deadly 2010 explosion in New Hampshire has agreed to surrender some money to the federal government in a separate wire fraud case in Maine.

Craig Sanborn of Maidstone, Vermont, is serving a 10- to 20-year sentence for manslaughter and negligent homicide in connection with the explosion at his Black Mag gunpowder plant in Colebrook. In Maine, he was convicted of stealing $300,000 in grant money relating to a munitions plant he ran in Brownville in the mid-2000s.

The Caledonian Record reports federal documents say the 67-year-old Sanborn has agreed to surrender at least a portion of that money to the federal government. The amount, $65,000, is in mutual funds held in IRA accounts.
