The shooting was reported around 1.30 p.m. on Thursday, September 23, at the supermarket located 30 miles east of Memphis, Tennessee.

Authorities arrived minutes later at 1.34 and began helping victims. Two medical helicopters were flown into the area to evacuate victims.

Those who were injured were taken to area hospitals and their conditions range from minor to extremely serious, authorities said.

Collierville Police Chief Dale Lane said in a press conference: “It breaks my heart to have to stand before you today. We’ve had an incident here in Collierville that has occurred all over the country. This is the most horrific event to happen in Collierville history.”

Both customers and employees were among those injured, Glenda McDonald, an employee at Kroger told FOX13 Memphis. While McDonald wasn’t injured, she was shaken. She only heard a gunshot and ran out the door, she told the Fox affiliate. “We found people hiding in freezers, in locked offices. They were doing what they had been trained to do: run, hide, fight,” Chief Lane told reporters at the scene. Brignetta Dickerson, a 33-year-old Kroger employee, told reporters that she saw one of her coworkers shot in the head and a customer shot in the stomach after the gunfire began in the deli.

Authorities said the shooter turned the gun on himself after killing one person and injuring multiple people. The Shelby County Sheriff’s office is helping with the investigation. Law enforcement officials believe the gunman acted alone.

Ralph Confer, of the Memphis Police Department, was on duty at Regional One Health medical center on Sept. 20, a day during which employees were holding a cookout in a police holding area. A medical technician who was also on duty asked if she could have a hot dog from the barbecue and one employee there told her she could.

Confer, however, told the woman she could not have a hot dog, WREG reported. She left, but came back later and asked a second person if she could have a hot dog, and was told “yes” by that employee.

But when Confer saw the woman fixing herself a plate, the police officer allegedly walked up to her and slapped the hot dog bun out of her hand, telling the woman she couldn’t have any food and had to leave through a back door.

The woman said she couldn’t leave through the back door and had to leave through the front, according to WHBQ, but Confer allegedly wouldn’t let her. As he tried to “corral her out the back door,” the police officer is accused of picking the woman up, causing her to hit her head on cabinets.
