The incident happened Sunday in Robeson County. The group, which is from Conway, South Carolina, was headed southbound.
Cathleatha Richardson spoke to ABC11 Eyewitness News via telephone Wednesday. She said her 23-year-old daughter and two members from her church were near exit 25 when they felt and heard a shotgun blast. The pellets hit the driver side door of their 2007 Dodge Nitro.
"I was begging God not to let him shoot us," Richardson said.
Richardson's daughter was driving.
"Whatever hit the car was so devastating that it vibrated my hand and she was yelling, 'Oh God, my ears, my ears,' So I told her to pull over real quick," Richardson explained.
They called 911 and after pulling over, they got out and saw several shotgun pellets had hit the vehicle. They got back into the vehicle and waited for help.
That's when Richardson said the suspect appeared at the passenger side window pointing a shotgun.
"He had a long gun, which may have been a shotgun, may have been a rifle, don't really know, a long gun," said Major Howard Branch, Robeson County Sheriff's Office. "He took the butt of the shotgun and tried to bust the window open."
The gunman wasn't able to break the glass, so he pointed the shotgun at the driver's head.
"And I jumped out the car and started yelling, 'Please don't kill my baby! Please don't kill my baby! Please don't kill my baby!' Richardson exclaimed. "And after that, he came around. He put the gun to my head."
The suspect robbed the passengers of several hundred dollars and fled on foot down Bucket Road.
