FORT MYERS, Fla.- Firefighters swarmed the scene of a duplex fire Monday morning.

It happened on the 1900 block of South Pine Drive, just off of U.S. 41 in South Fort Myers.

South Trail Fire & Rescue responded to the scene around 8:30 am, and were able to contain the blaze within the single unit of the duplex.

A single mother and her 11-year old daughter live in the duplex, but were not home when the fire started. Family members of the woman say she does not smoke.

Neighbors spotted the smoke seeping from the air vents of the duplex and quickly called 911.

"We walked around the house and the front window was smoking and it was really hot. I thought someone was in there. I kept knocking on the door but no one answered the door," said Edwin Duarte, a neighbor of the victims.

Fire investigators are still trying to identify the cause of the fire. They believe it started in the bedroom of the home. Fire investigators say fire and smoke caused about $5,000 in damages to the duplex.

The Red Cross is being called in to provide assistance for the family during their time of need.
