Gwinnett County police investigators are releasing new details in the brutal attack of an employee inside the Grayson Kroger early Sunday morning.

According to the police report, 59-year-old Maria Mosher had just arrived at work at 5am Sunday and was putting her things inside her locker in the break room when 21-year-old Akin Williams attacked her from behind.

“She was knocked on the ground and he repeatedly, not only stabbed her, but punched her in her face and her body,” says Cpl. Michele Pihera.

She tells WSB’s Sandra Parrish the attack lasted for 30 minutes. Every time Mosher would try to escape, he would beat her again.

After trying to clean up the scene, surveillance video shows him leave the break room and clean his hands in the meat department. He then goes back to the break room.

At 6am, another employee finally enters the break room and sees Mosher on the floor. When questioning Williams, he says he has it “all under control” and had already called 911.

When the employee went to check on the ambulance and realized it wasn’t coming, she went back to break room and Williams was gone.

Because the store wasn’t yet open and the doors remained locked, Williams was unable to escape. He was arrested inside the store when officers arrived.

Pihera says its Mosher is fortunate to be alive.

“She is in stable condition, thankfully, at a local hospital being treated for her injuries. We are just so thankful that she was able to survive the injuries and hopefully will be able to give more details to investigators as to why this took place,” she says.

According to the police report, Mosher was able to tell officers at the scene that Williams didn’t like her and wasn’t “right in the head”.

Another employee told police Williams had asked her for a knife the day before saying he needed it to open boxes. He was not given one at the time. Williams was also not scheduled to work the day of the attack.

He has been charged with kidnapping, false imprisonment, and aggravated assault.
