NATCHEZ — A Sunday night fire destroyed a house at 103 Lindberg Ave., fire officials said.

The two occupants of the house were able to escape the blaze unharmed after smoke detectors alerted them to the fire that investigators said they believe started in the garage of the house.

The house was fully engulfed in flames when firefighters arrived, said Ventris Green, Natchez fire chief.

“We got the fire under control in 20 minutes,” Green said. “It spread throughout the whole house.”

One firefighter sustained a minor superficial burn on his right shoulder, Green said.

Neighbors said they heard an explosion come from the house at approximately the time the fire was discovered, and Green said the noise likely came from two vehicles that were in the garage.

“Two vehicles in there, burned up,” Green said, adding a vehicle could have been the source of the fire. “Once the car got going, anything inside there (the garage) could make a noise, like the gas tank. They didn’t have any type of propane tanks.”

Green said he estimates 70% of the house was destroyed in the blaze.

“They did a good job to get that type of fire under control within 20 minutes,” Green said of the firefighters.

Fire Marshal Ryan Jones said the cause of the fire is under investigation.
