Julie Eberly, 47, was shot and injured on Interstate 95, north of Lumberton, North Carolina, on Thursday.
Authorities were called to the scene by Ms Eberly’s husband Ryan Eberly, who was driving the couple from their home in Pennsylvania to Hilton Head Island, South Carolina.
The Eberlys car approached the suspect’s vehicle, blending into a different lane moments before the shooting, investigators said.
The suspect then went to the side of the couple’s car, rolled down his window and opened fire towards the vehicle, with a bullet coming through the car door and hitting Ms Eberly.Read more:
Her husband was not injured in the shooting. Ms Eberly was transported to a local hospital where she was pronounced dead later that day.
Witnesses told the sheriff’s office that the suspect immediately walked away from the scene, taking the first exit off the freeway.
Police asked the public for help in identifying the suspect who was driving a silver 2010 Chevrolet Impala or Malibu with tinted windows and possibly chrome around the frames.
Robeson County Sheriff Burnis Wilkins said none of the couple’s six children were in the car at the time of the shooting.
“It was an innocent family from Pennsylvania going to the beach for a vacation,” Sheriff Wilkins said. “Fortunately, they had left their six children at home with their grandparents, but now these children have to live with the idea of their mother being murdered in such a cowardly and senseless way.
