ST. LOUIS (AP) — Police say an off-duty officer has fatally shot a man who was attempting to rob a St. Louis gas station.

The St. Louis Post-Dispatch reports the officer, who was in street clothes, stopped at a Shell station late Tuesday after getting off work. Interim Police Chief Lawrence O’Toole says the officer was inside the store with two clerks when a man walked in, pulled out a gun and demanded money.

Police identified that man as 33-year-old Chazz Brown, whose last legal address was in Columbia.

O’Toole says Brown and the officer both fired, but only the suspect was hit. He died at the scene and a handgun he’s believed to have used was recovered.

The gas station is across Interstate 55 from the Anheuser-Busch Brewery.
