Spontaneous combustion was the cause of a weekend barn fire near Hallsville.

Investigators said some overheated grass clippings caused the fire on Sunday afternoon on North Phillipe Road.

The fire destroyed a barn, a shed and several vehicles.

Boone County and Columbia firefighters had the flames under control in less than an hour.

No one was hurt.

Fire officials estimate the damage is about $30,000.

Property owner Donn Bennish told KRCG 13 that he was just about to take a nap when a neighbor saw the fire and called 911.
