Investigators believe an Austell man ran a red light Monday night in west Cobb County, causing a crash that killed him.

Scott W. Johnston, 32, was driving a 2015 Toyota Corolla southbound on C.H. James Parkway around 8:15 p.m. when he went through the intersection with Richard D. Sailors Parkway, near Powder Springs, Sgt. Dana Pierce with Cobb police said.

Johnston’s Toyota collided with a 1998 Mercedes ML 320 that was traveling westbound on Richard D. Sailors, Pierce said.

Johnston died at the scene of the wreck. The driver of the Mercedes, Karyne N. Pierre, 19, of Hiram was taken by ambulance to WellStar Kennestone Hospital for treatment of non-life threatening injuries, police said.

“As both automobiles entered the intersection they struck each other, causing both to come to an uncontrolled stop near the southwest corner of the intersection,” Pierce said in an emailed statement. “Based on witness statements, investigators believe Ms. Pierre had a green traffic signal and Mr. Johnston had a red traffic signal.”

No charges are expected to be filed in the crash, which remains under investigation.
