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.
No one was hurt.
