A fire marshal is investigating an explosion and fire in an upscale neighborhood. One man who lived in the house is hospitalized with burns.

The fire was reported about 10:15 Sunday night in the 7500 block of West Persimmon Court off Highway AB. Someone in the area heard an explosion and called 911. The east side of the house is destroyed.

Crews from at least six fire departments showed up to help; some stayed there much of the night.

"The flames were coming out of all the windows of the house, the garage door was blown approximately 40 yards to the west side of the structure. Every window of the house was blown out," said Willard Fire Chief Ken Scott.

Emergency responders thought the injured man would survive.
