A motorcyclist was killed and his passenger was seriously injured in a Cobb County crash with a pickup truck driver who was believed to be under the influence Thursday evening, authorities said.

The vehicles collided around 11:20 p.m. at the intersection of Veterans Memorial Highway and Cooper Lake Road in Mableton, according to Cobb police. The 24-year-old motorcyclist, identified as Stacey Miles Davis of Lawrenceville, was pronounced dead at the scene by the county medical examiner’s office. His passenger, Mya Smith, 23, of Powder Springs, was taken to Wellstar Kennestone Hospital with serious injuries to her leg and hip and “severe” cuts to her face, according to an arrest warrant.

The driver of the truck, Donald Bryan, 42, of Mableton, is accused of being impaired during the crash, police said. He was taken into custody.

An investigation determined that Davis and Smith were traveling west on Veterans Memorial Highway on a Harley-Davidson motorcycle when Bryan tried to turn onto Cooper Lake Road from the eastbound lanes. Police said Bryan made an unsafe left turn into the path of the Harley, which hit the rear passenger side of his vehicle.

Davis was still aboard the motorcycle when it came to rest alongside the truck. Smith was thrown off and landed in an eastbound lane.

“Both vehicles caught fire after the collision and had to be extinguished by the Cobb County Fire Department,” police said.

Bryan was booked into the Cobb jail and is facing charges of first-degree homicide by vehicle, serious injury by vehicle, driving under the influence of alcohol and failure to yield while turning left, according to jail records. Bryan allegedly admitted to drinking four beers and provided breath samples that tested positive for alcohol, the warrant states.

The crash remains under investigation. Anyone with information is asked to call Cobb police at 770-499-3987.
