The man accused of killing two people and injuring a police officer at a Walmart in Mississippi on Tuesday is a longtime employee who was recently suspended, authorities say. Martez Tarrell Abram, 39, is facing two counts of murder over the shooting at the Southaven store, CNN reports. Employees say Abram was working at the store, which is around 13 miles south of Memphis, until Monday, the Jackson Clarion-Ledger reports. Authorities say Abram, who had no previous police record, was disciplined over an incident a few days earlier that led to a police report being filed but no charges. They say that in the incident, Abrams had a knife in his belt and he showed it to another employee, but apparently didn't threaten anybody with it.
Investigators say Abrams entered the store around 6:30am and killed two Walmart employees—supervisor Brandon Gales, 38 and 40-year-old store manager Anthony Brown—before he was wounded in an exchange of fire with police. An officer was shot but was saved by his bulletproof vest. Abram also set a fire inside the store, police say. Stonehaven Mayor Darren Musselwhite says there is "a lot of sadness" in the town after the shooting, the New York Times reports. "I personally knew the store manager, so I’ll admit it’s pretty tough on me," he says. "It's a nightmare. It is the kind of event that everyone dreads." Walmart US President and CEO Greg Foran said in a statement that the "entire Walmart family is heartbroken by the loss of two valued members of our team." (Read more Walmart stories.)
