After opening fire in the store, the suspect, identified as Jarid Haddock, 21, ran across the street and fired into a vehicle, forcing the driver to move to the passenger seat. The suspect stole the car and fled, police said.
Following an hours-long manhunt, a relative of Haddock called authorities to a location behind warehouses where Haddock was hiding. Gunshots were heard while police approached and a man who identified himself as Haddock was found wounded, Murray said.
No officers were injured or used any force, he added.
Haddock died of his injuries at the scene.
