A fire in Newtown last night may have been sparked by a lightning strike. Firefighters responded to the Chestnut Hill Road home on a report of the strike and smoke seen by a neighbor coming from the structure. Heavy smoke was found inside. Sandy Hook Fire Chief Bill Halstead says there was a flare up in one of the walls so they had to open it up, all the way to the second floor. No one was home at the time and no firefighters were injured during the response.
