Clayton County police have arrested the driver of a tractor-trailer that struck and killed a woman standing outside her disabled car on the shoulder of an interstate late Thursday night.

The victim, whose family identified her as Jamecca Parris-McKnight, 31, was traveling with a child and was stopped on I-675 northbound near Anvil Block Road before she was hit at about 10:30 p.m. She was pronounced dead on the scene, and the child was taken to a hospital with minor injuries.

According to Channel 2 Action News, Parris-McKnight is the child’s mother.

The wreck occurred after witnesses saw the driver of the tractor-trailer, John Nichols, 59, swerving in and out of lanes, police said. It is not known what caused the driver to lose control.

After attempting to steady the vehicle, police said the tractor-trailer driver then jackknifed across all lanes of I-675 northbound, causing traffic to come to a stop.

Nichols, who is from the Tampa area of Florida, was arrested on charges of vehicular homicide and failure to maintain lane.
