BRENTWOOD, N.H. (AP) — Authorities say a New Hampshire police officer was shot to death after he responded to a domestic disturbance at a home that later exploded and burned.

The gunman is presumed dead in the ensuing blaze.

Attorney General Joseph Foster says Monday night 48-year-old Steven Arkell of Brentwood was shot to death when he answered the call in a suburban neighborhood.

After the shooting, the house burst into flames. A massive explosion blew the front off the house and within an hour, it was leveled.

Foster says 47-year-old Michael Nolan, the son of the homeowner, is the suspected gunman. He is presumed dead.

A third person was taken to a hospital.
