A woman who was shot on I-85 during her Tuesday morning commute remains in the hospital and needed surgery, authorities said.

The woman told Coweta County deputies that a man in a ski mask shot her while she was driving between the Newnan and Fairburn exits about 5:45 a.m., sheriff’s office spokesman Toby Nix confirmed in an email to The Atlanta Journal-Constitution.

She said a gray Buick pulled up beside her, and a man wearing a black ski mask aimed a gun at her and fired. The victim was taken to Grady Memorial Hospital. The woman’s identity has not been released, and Nix did not have further information about her condition Wednesday afternoon.

There was heavy police activity on the interstate for hours Monday morning as officers investigated.

Anyone with any information regarding this incident is asked to contact the sheriff’s office at 770-253-1502.
