Update: Fire investigation underway in Madison

MADISON, Ala. - The Madison Police Department blocked off a portion of Highland Drive while they investigate a house fire they believe to be suspicious earlier this morning. The area blocked off was between Cherry Road and Spring Water Drive.

Crews arrived to the house in the 800 block of Highland Drive around 1:15 a.m. They found a two-story house fully-engulfed in flames.

It took firefighters roughly an hour to get the flames under control.

Someone in the area told us something inside the house exploded before crews arrived, which seemed to be confirmed by the glass seen in the roadway. Neighbors say they haven't seen anyone in the home for a couple of weeks.

Neighbor Stephanie Diei said the fire was really scary. "I tried to look out my window, and all I could see was police lights, so I couldn't get a good angle until I came out my door," Diei explained. She said all the neighbors were outside watching the fire.

Crime scene investigators are working to determine the cause of the suspicious fire.
