Attorney General Joseph Foster of New Hampshire validated Wednesday a Manchester man’s use of deadly force against two men who kicked in his apartment door in the middle of the night earlier this month. Ian Peters, his fiancee, and her 3-year-old son were asleep in their Lake Avenue apartment when Peters awoke to footsteps on the porch outside their bedroom. He also heard someone attempt to turn the doorknob of the apartment’s front door. When the door did not open, according to Foster’s report, two men kicked it open and rushed in. One of the intruders, Michael Larocque, 24, was fatally wounded in the ensuing fight.
