Fire Investigators in Lee County are trying to determine what caused a home in Lehigh Acres to burn down late Sunday night.

The fire broke out in the 6000 block of Susan Avenue, off Cemetary Road before midnight.

The fire took about 45 minutes to put out, but continued to smolder hours later.

Firefighters tell WINK News a woman lived in the home, but is believed to have made it out safely.
