An elderly woman says she was awoken by smoke alarms to find a fire engulfing her Marrero home Tuesday morning.

Firefighters are trying to determine what caused the house fire in the 6100 block of Singleton Drive early Tuesday.

88-year-old Marion D. Fisher said that she believes the fire started in a bathroom. Firefighters confirmed that the fire was caused by a bathroom heater.

Fisher said she was the only person living in the home and no one was hurt. The home was severely damaged by the fire.
