LUMBER BRIDGE — A fire truck was damaged recently when a shotgun in a burning home discharged because of the heat, striking the vehicle with buckshot, according to sheriff’s Lt. Brian Duckworth.

Duckworth said no one was injured because of the fire or the shotgun blast.

According to Duckworth, Gary Wayne Livingston called 911 at about 9 p.m. on Dec. 21 to report that a Christmas tree was on fire at his mobile home on the 1200 block of McIver Road in Lumber Bridge.

Duckworth said that a 12-gauge shotgun that was mounted on a wall discharged because of heat that had exceeded 300 degrees, blasted a hole in the wall and shattered windows on the back of a fire truck belonging to the Parkton Volunteer Fire Department.

The buckshot flew through an area of the truck where firefighters sit to put on gear, according to Duckworth, who said it was fortunate no one was seriously injured.

He estimated damage to the truck at $3,000 to $4,000.

Duckworth said that investigators are still trying to determine the cause of the fire, which started in the living room. He called the fire “suspicious.”

Livingston’s wife and four children were not at the home when the fire started.
