A family of nine escaped an early Sunday morning blaze when they heard the fire roaring and saw the flames right before their smoke detector went off, a St. George Fire Department spokesman said.

No was injured, but the house at 7808 Blake Drive in the Antioch Villa subdivision is considered a total loss after the roof collapsed in the back of the house and utility lines had to be severed, Eldon Ledoux said.

The cause of the fire, which started in the carport, is undetermined and under investigation, Ledoux said.

St. George firefighters responded to the home at 12:27 a.m. and saw the carport was completely engulfed in flames.

Firefighters declared the fire under control at 12:58 a.m., Ledoux said.

The two vehicles under the carport were destroyed, Ledoux said.
