At least one person is dead and 14 are injured in a shooting Thursday afternoon at a Kroger grocery store in Collierville, Tennessee. Collierville Police Chief Dale Lane confirmed the shooter is dead from a self-inflicted gunshot wound.

A spokesperson from a nearby hospital said there were nine patients related to the shooting and four were in critical condition.

Collierville police have searched the shooter’s van, which was left in the parking lot. Lane has not said what kind of weapon the gunman used and would not confirm if the gunman worked at the store. There has been no motive given for the shooting.

The shooting was reported at 1:30 p.m. local time at the Kroger in Collierville, roughly 30 miles east of Memphis. According to survivors and eyewitnesses, shoppers ran out of the store when the shooting began.  

Glenda McDonald, who works in Kroger’s floral department, said she “just ran out the back door” when the shooting began, leaving her purse and keys. McDonald believes she saw a bagger and some customers get shot before fleeing the building.

Brignetta Dickerson, who worked at Kroger for 32 years, told CNN affiliate WMC she was working the cash register when the shooting began, saying she tried to run and hide with some of her coworkers but the shooter was right behind them and opened fire. 

“He kept on shooting, shooting, shooting,” Dickerson said. “He shot one of my coworkers in the head, and then shot one of the customers in the stomach, and then my other customer got kinda like cuts from the asphalt.”

Lane confirmed the victim’s death in a news conference.

“It breaks my heart to have to stand here today, it’s horrific,” he said. “This is the most horrific event that we have had in Collierville’s history." 

According to Lane, police found people hiding in freezers and locked offices, doing whatever they could to keep themselves safe. The victims have been transported from the scene to multiple hospitals in the area. 

It remains unclear how many people were in the grocery store at the time of the shooting but there are multiple witnesses. 

“I’m very thankful. I watched guys that ran into the front of that building knowing that — historically, not in this case but historically — many of these shooters have very high-powered rifles. And not one of them hesitated going in that front door,” Lane said.
