BEAVER DAM -- Firefighters responded to a house fire at 16488 Beaver Dam Road on Thursday morning.
Neighbors heard an explosion and stepped outside to see smoke and flames coming from the home, Box Elder Chief Deputy Kevin Potter said.
Firefighters arrived around 11:50 a.m. and contained the fire, which had fully engulfed the house.
The homeowner was unaccounted for during the incident. For safety reasons, fire investigators could not enter the remains of the structure to find a cause and to see if the man was in the home, Potter said.
