It happened about 4:30 Friday afternoon.
A man in his late 40s shot himself inside an SUV in the parking lot and walked into the store, metro police spokesman Dwight Mitchell said. The man then collapsed and died.
Frightened customers and employees inside the store could not leave the store, nor could anyone go inside, while police conducted their investigation.
First calls reported that a bloodied man with a gun had walked into the store, police said.
