NEWTON COUNTY, GA — A deadly overnight shooting at a Walmart and nearby home has left two people dead and one person critically injured, according to the Newton County Sheriff’s Office.

Authorities say the violence began around 1:30 a.m. at the Walmart on Salem Road in Covington, when an employee identified as Dwayne Eduh left the store, retrieved a gun from his vehicle, and returned inside. Eduh allegedly shot and killed a fellow employee, now identified as 21-year-old Khalaf Barksdale, inside the store.

As Eduh was leaving the store he shot another employee, Ryan Bradley, who is now in critical condition.

“He came back inside, located another individual, and shot and killed him. As he was on his way out of the store, he located another individual and shot him,” said Sgt. Jack Redlinger with the Newton County Sheriff’s Office.

Investigators say Eduh then went to a nearby home on Emerson Trail, where he shot and killed a young woman identified as 19-year-old Akeela Clark. He later shot himself on Interstate 20, according to deputies in South Carolina.

Officials confirm Eduh is in custody, and say all the victims were known to him. There is no word on a motive yet.

The Walmart store remains temporarily closed.

The investigation is ongoing.
