COLLIERVILLE, Tenn. (WREG) — Multiple people were injured Thursday in a shooting inside the Kroger on Byhalia and Poplar Avenue in Collierville, a Memphis suburb, after an active shooter incident officials are calling the “most horrific event” in the town’s history.
Collierville Police Chief Dale Lane confirmed 13 people were shot, and one person killed. The suspected shooter also is dead, possibly from a self-inflicted gunshot, Lane said.
Friday, Lane said the number of victims shot had risen to 15. The number of deaths remained at one.
A family member and a Collierville alderman has identified one of the victims as Olivia King.
The suspect’s vehicle is still parked and is being investigated. Sources say the suspect was a sub contractor who did work in the store’s deli department.
Lane said officers entered the store just after 1:30 and found multiple people shot, and employees in hiding. He could not comment on whether the shooter was an employee, saying it was under investigation.
Lane called it “the most horrific event that’s occurred in Collierville history.”
Multiple witnesses report hearing at least a dozen shots. Some customers made it out of the store. Employees had others take shelter in the cooler, witnesses said.
One employee named Brignetta Dickerson, who says she’s worked at the Kroger for 32 years, told WREG she hid with her coworkers and several customers when they heard the gunshots.
She said her only concern was her customers and coworkers.
“I’m still in shock right now,” said Dickerson. “But I was calm. I was calm and told the customers and my co-workers ‘Just sit down and relax. You’ll be okay.'”
Jean Kurzawski said she worked in the back of the Kroger and heard noises toward the front entrance. She thought balloons were popping at first until she saw customers running. She escaped out a back exit and said she heard gunshots continuing behind her.
“I was just thinking, oh I’m gonna die, I’m gonna die, he’s gonna shoot me,” she said.
Collierville High School was briefly sheltering in place.
Multiple ambulances were seen entering Regional One Hospital in Memphis. The hospital reported it saw nine patients, four in critical condition and five non-critical.
