The family says over the weekend a man came to their door in the middle of the night asking for a ride and for help. They called 911, and a short time later someone came to the back of their house and started a fire.
A neighbor's surveillance camera captured huge flames shooting from the back of the home as a propane tank went off after 6 a.m. Earlier in the morning, the man accused of starting the fire can be seen walking right by the camera, although the video is blurry.
The family says they managed to put the fire out, but it must have rekindled and became a roaring blaze hours later.
Anyone with information is asked to call the Harris County Fire Marshal Office at 281-436-8000.
