Gwinnett County Fire investigators are attempting to determine the cause of a deadly house fire that claimed the life of one person and injured another.

Crews were dispatched to the 1900 block of Flowery Branch Road in Auburn just before 8 p.m. Saturday evening. Firefighters arrived seven minutes later to find a two-story Cape Cod style home fully engulfed in flames according to Gwinnett County Fire and Emergency Services public information officer Lt. Eric Eberly.

“First-due companies were made aware of an entrapment and despite the concern for the firefighters own well being, crews immediately entered the residence in an offensive mode - rescue priority,” Eberly said in a released statement. 

Firefighters found an adult male in the front hallway and removed him to safety. The male advised a second victim was still inside the home.

“Fire crews once again, entered the blaze to effect a second rescue,” Eberly said.

The female victim was found motionless in a front bedroom. Firefighters removed the victim from the house only to realize she was already deceased.

The male victim was transported to Gwinnett Medical in Lawrenceville. No firefighters were injured.

The exact cause of death of the female victim remains under investigation. The cause of the fire is also undetermined.
