The shooting took place on the southbound U.S. 75 Frontage Road between Campbell and Belt Line roads at about 6:30 a.m.

Police said Thursday afternoon they were still searching for the shooter, who drove off headed east on Arapaho Road in a white vehicle after the shooting.

Thursday afternoon Richardson police released surveillance video showing a white, four-door 2012 Toyota Camry sedan leaving the scene.

Witnesses told police they heard two drivers arguing at the intersection of the service road and West Arapaho Road before before hearing a single gunshot.

Hitalo Villa was driving to work when he saw the victim's car driving very slowly along the service road.

"I was thinking the guy was sleeping and I stopped and I try to help and try to wake him up," Villa said. "When [the car] was getting close to the freeway I knew I had to do something."

Villa did not witness the shooting or what led up to it.

Villa got out of his wife's car, ran to the passenger side of Klikus's car and punched the window until it shattered.
