This happened on the road behind mine. We didn't hear an explosion...all we heard were all the fire trucks.
I talked to one of the residents of the house. He said his brother heard someone at the door and the next thing they knew, the house was on fire. They saw someone running off. A neighbors camera caught the person who was at the door.
This same person apparently was going up and down the street knocking on doors at 4:30 am....white dude wearing a camo jacket and Air Jordan type shoes......
