NORTH CAPTIVA ISLAND, Fla. - The smoke could been seen for miles as a fire raged out of control on North Captiva Sunday morning. Two homes were destroyed in the process.
All that remains of a $1.5 million home is charred wood and twisted metal. Fire Chief Richard Pepper says the cause of the fire on Kingfisher Drive is still under investigation, but suspects a malfunctioning generator is to blame.

He says composite building material, made out of plastic, is the reason the house caught fire so quickly and leveled within an hour.

"The intensity of this fire, we had not witnessed anything like this. We have watched a lot of pressure treated wood decks go up and they're kind of slow buring. This one exploded," he said.

The fire destroyed a neighboring home. The heat also melted the side of Shari Blevins' home. When she saw the wall of fire she says grabbed her cat and ran out the door.

"I looked over and I heard a loud explosion and I looked out that window and there was a a sheet of flames. It was all orange. It was from the bottom of the house coming under the house to the very top," Blevins said.

Fire crews will be out here the rest of the day and into the evening monitoring hot spots.
