Two people were killed in separate incidents Thursday morning, but neither is expected to be the result of foul play.

Stacey Renee Stallings, 34, of Covington, was found dead in her pickup truck around 5:45 a.m. in the turn lane of a subdivision off Kirkland Road. The door of the truck was slightly cracked, according to Lt. Keith Crum of the Newton County Sheriff's Office.

Coroner Tommy Davis said the cause of death is still under investigation and the body has been taken to the Georgia Bureau of Investigation's Medical Examiner's Office for an autopsy.

About half an hour later, 37-year-old Thomas James Daugherty, was walking along Ga. Highway 36 when he was struck and killed by a 62-year-old Covington woman. The accident took place near Aiken Way, just south of Newton Factory Bridge Road.

The driver hit Daugherty with her Hyundai Santa Fe around 6:15 a.m., according to Georgia State Patrol spokesman Gordy Wright. At first, she believed she had hit a deer and called authorities to report the accident, but a motorist driving by later saw the victim in the a ditch around 7:15 a.m., Wright said. The man's car reportedly broke down on the highway, north of the scene of the accident, and he was likely walking to the nearest gas station. He was wearing a tan jacket at the time of his
death; alcohol and drugs are not suspected, Wright said.

Coroner Davis said his office has been having trouble contacting the man's family.
