On Thursday night at 9:46 p.m., one Hundred Firefighters were called to a single family dwelling on Smallwood Church Road in Indian Head for a fire. Firefighters arrived and found a large volume of fire in the roof area.  A structural collapse of the roof structure occurred shortly after arrival, necessitating a defensive attack.  Firefighters were unable to extinguish areas of hidden fire and made the determination  to allow the fire to burn until it was accessible by master streams the following morning. The smoke alarms were activated and alerted the occupants. It took the firefighters 14 hours to control the blaze. The estimated loss in the fire was $750,000. The fire is under investigation by the State Fire Marshal's Office.
