Two people were killed and two people were injured in a shooting at the Walmart in Southaven, Mississippi, Tuesday morning, according to authorities.

At 6:33 a.m. Southaven police began getting 911 calls about an active shooter at the Walmart Supercenter located at 6811 Southcrest Parkway, Police Chief Macon Moore said during an 11 a.m. news conference. Officers arrived on the scene about three minutes later, where they found the suspect in the west parking lot, Moore said.

The suspect was confronted by two officers. One officer was shot but was saved by his bulletproof vest. The other officer shot the suspect twice and the suspect was taken into custody. The suspect was taken to Regional One Medical Center. The wounded Southaven officer was taken to DeSoto Baptist Hospital where he is recovering, The Commercial Appeal reported.

The suspected shooter was also an employee at the Walmart until Monday, The Commercial Appeal reported. Southaven Mayor Darren Musselwhite described the suspect as a disgruntled worker.

He was identified later Tuesday by District Attorney John Champion as Martez Abram. He is being charged with two counts of murder. The 39-year-old is from Southaven.

The two people killed were Walmart employees, the company's CEO of U.S. operations, Greg Foran, said in a statement.

"We’re deeply saddened by the reports from our store in Southaven, Mississippi. We are working with local law enforcement and will continue to update as we learn more. Our hearts are with the victims, their families and the entire Southaven community," said a statement issued by Walmart.

The victims were identified as store manager Brandon Gales, 38, and Anthony Brown, 40. Gales was identified by his father. Brown was identified by the DeSoto County Coroner's Office.

There were 60 employees at the Walmart at the time of the shooting, Moore said.

Walmart customer Phil Cox had just left the self checkout machine and walked out the front door. He said he heard a gunshot and then two more as he immediately headed for his vehicle.

The time stamp on his receipt for Flo Nase is 6:30 a.m.

Cox, 70, of Forrest City Arkansas, said police arrived and he immediately heard six gunshots. He assumes police were firing. Cox said others gathered in the parking lot told him the shooter fired upon a manager of the Walmart, who was outside, and then fired at two other employees.

Cox said he never felt threatened.

"I think the guy was going after employees,'' he said.

The Mississippi Bureau of Investigation was called in to investigate the officer-involved shooting while the Southaven Police Dept. conducts the criminal investigation of the assault on the Walmart employees, Chief Moore added.
