UPDATE: Man Dies in Potomac House Fire

Update, 3 p.m.: Montgomery County Fire and Rescue have determined the fire started on the kitchen stove top, Assistant Chief Scott Graham wrote in a press release.

A total of 65 Montgomery County Fire and Rescue personnel were called to the two-story house at 8509 Scarboro Court at 4:35 a.m. They found heavy fire in the kitchen area on the first floor.

One elderly unconcious man was found on the second floor. He was transported to Suburban Hospital and advanced life support treatment was initiated immediately but he was pronounced dead a short time later, according to the release.

A second elderly male was found in the house and was treated for smoke inhalation.

The survivor said they had been cooking. A heavily damaged sauce pan was found on the stove top, according to the release. 

"It appears the fire burned for some time before being seen by the neighbor after it vented through the kitchen window," the release said.

Fire and Rescue crews brought the fire under control in 25 minutes. The name of the deceased male has not yet been released.
