Officials said the shooting call came in around 1:30 p.m. at the Costco on North Pointe Drive.
The victim, Ryan Ware, was shot in the stomach, according to authorities. Police said he was taken to the hospital and is in critical condition.
Ware is a graduate student at Duke's Divinity School. On Monday, the Dean of the school released a statement saying, "We have been surrounding the victim and his family with love, support and prayers."
Police believe Ware was targeted but are not clear why.
"It's sad someone would target someone ... an innocent person who has their life ahead of them," a woman who was inside the store when the shooting happened told ABC11.
Police are still looking for the person responsible.
Witnesses said they saw a grayish sedan drive away from the scene.
