Steven Theriault, 28, of Howland, is serving an initial four years behind bars, with four more suspended, in connection with an incident in which he held a box cutter to his girlfriend’s throat and threatened to kill her.

In a news release Monday, the FBI said it was working with police in Skowhegan, Waterville and Pittsfield to identify the person responsible for four bank robberies in the Waterville area, each of which was reported in separate years during the winter.
