BANGOR – Federal prosecutors say a Hampden man will spend 2½ years in prison for conspiring to make false statements to a federal firearms dealer. Judge John A. Woodcock sentenced 31-year-old Michael Campbell on Wednesday. Woodcock also order Campbell to spend three years on supervised release. Court records say Campbell went to a federal firearms dealer in Brewer twice in June 2012 and falsely completed federal firearms applications forms. The records say Campbell represented himself as the buyer of the handguns when he had actually been asked to purchase them by people prohibited from doing so under federal law.
