Police at the scene of a reported shooting in a Mississippi Walmart.

A disgruntled former Walmart employee allegedly went on a shooting rampage at his former Mississippi store early Tuesday, killing two employees and wounding a cop, according to authorities.

Martez Abram, 39, allegedly shot former co-workers Brandon Gales, 38, and Anthony Brown, 40, at the Southaven store, according to WREG.

A responding officer was also shot, but was saved by his bulletproof vest, police told the outlet.

Another cop finally ended the carnage by shooting the gunman twice, Southaven Police Chief Macon Moore told reporters.

Southaven Mayor Darren Musselwhite described the suspect as a disgruntled worker with “a personal grievance with his employer.”

“It wasn’t an accident,” said colleague Travis Jones, who was working when he heard shots.

“He knew what he was doing when he came in there.”

Abram is charged with two counts of murder, but may be hit with more charges when he is released from a hospital, said DeSoto County District Attorney John Champion.
