A police barricade triggered by a domestic dispute ended in a huge explosion in a New Hampshire neighborhood on Monday.
Authorities were called to a home on Mill Pond Road in Brentwood after a report of shots fired, according to Boston TV station WHDH.
The first officer to respond, Steve Arkell, was fatally shot, Attorney General Joseph Foster told CNN.
“Other officers arrived and a short time later the home was engulfed in flames,” Foster said.
Video showed the flames quickly spreading throughout the house and within minutes a huge explosion destroyed the home.
The alleged gunman, Michael Nolan, was killed in the blast, according to Foster.
It was not known how the fire started.
