MIDLAND - Still no final word on what sparked a blaze that burned up a Midland business, just south of town on Wednesday night.
Fire fighters say the flames started in the attic of a deer processing store, between 7:30 and 8:00, near cotton flat road.
Investigators think the AC unit is the culprit.
More than 1500 feet of the building was damaged.
Heavy smoke got the rest of the building.
