A Maidstone man convicted in 2013 of manslaughter and negligent homicide in the Black Mag gunpowder plant explosion

A Maidstone man convicted in 2013 of manslaughter and negligent homicide in the Black Mag gunpowder plant explosion in Colebrook that killed two men is seeking an early prison release. On Monday, Craig Michael Sanborn, 73, filed a motion asking Coos Superior Court to award him four months of earned time reduction. He is currently serving a sentence of 10 to 20 years in the Northern New Hampshire Correctional Facility in Berlin and has a minimum release date of Nov. 23, 2023 and a maximum of November 2028. In his motion, Sanborn included the signed recommendations from New Hampshire Department of Corrections Commissioner Helen Hanks. As of Thursday, the judge had not yet ruled on Sanborn’s motion for early release.
