Fredericksburg Fire Department spokesman Mike Jones said today that the cause of a house fire at 604 Woodford St. early Wednesday morning is officially being listed as "undetermined" because of the amount of contents in the home and the damage.

Jones said the fire marshal has interviewed the homeowner and determined that there does not appear to be anything in the debris burn pattern or the contents that would lead him to believe the fire was suspicious in nature and that the fire appears to have been an accident.

Fire fighters and medics responded to the home in Normandy Village after a neighbor across the street called 911 at about 4:25 a.m. Fire fighters found heavy fire and smoke coming from the one-story 1950s home, Jones said. The fire and heat also touched the neighboring home at 606 Woodford St. causing damage to the left side of the home near the roof and damaging an electrical wire attached to the house. Virginia Dominion Power had to shut off power to that home until the scene was under control.

Jones said a majority of the fire was contained and extinguished within 25 minutes of arrival of the first units. All occupants of both homes had exited safely, but one dog and a cat did perish in 604 Woodford St. The two occupants of that home, a mother and her son, were taken to Mary Washington Hospital for non-life threatening injuries. Two firefighters were treated for minor heat related issues at the scene.

"Firefighters spent several hours removing and wetting down contents to make sure no fire extension was found," Jones said.

The Fire Marshal's Office determined that the origin of the fire appeared to have been in the rear right of the house in the enclosed garage area. The damage is estimated to be more than $75,000.
