BURIEN, Wash. -- The search for a gunman who terrorized drivers on SR-509 continued Wednesday night after the highway near Sea-Tac Airport was shut down for more than five hours.

State Patrol trooper wrapped up their search for evidence and the person that opened fire on at least four cars.

No one has been hurt, but the gunman remains at large.

The shooting took place along SR-509 near the south side of the airport sometime around 1:30 p.m., troopers said.

Investigators say whoever did this was on the side of the highway and not in a moving vehicle, based on the trajectory of the bullets. All four cars were hit on the driver’s side of their cars.

Detectives don’t have any reason to believe that the vehicles were targeted.

Troopers said since it was a chaotic scene, they are still trying to confirm a timeline of when all the shootings happened and if more shots were fired after the initial four cars were shot.

"When we're arriving at things like this, we are putting on our active shooter gear-which is a blessing to have—the heavier vests that stops rifles and helmets,” said Trooper Rick Johnson.

At one point, troopers shut down both directions of SR-509 between 160th Street to Des Moines Memorial Drive. The western-most runway at Sea-Tac Airport was also closed "out of an abundance of caution," according to airport spokesperson Perry Cooper.

The southbound lanes and one northbound lane of SR 509 and one northbound lane of SR-509 were reopened around 6:30 p.m. All lanes were back open around 8:45 p.m.

One of the bullets went through the windshield of Mary Ertl's car.

"I heard a boom and then glass all over my face," she said. "I thought it was a rock until I looked at the passenger side, and then I knew it was a bullet... So I slowed down, and called police."

Another driver who's car was hit showed a bullet hole in his driver's side door.

"Was just about to go back to the office and just heard a loud bang," said Mike Luiz. "The bullet hole is through the bottom part of the door and went into the seat -- so the bullet's in the seat somewhere.

"I feel like I was more lucky because where the bullet hole entered and exited," he continued. "Some of the other people had higher-up shots fired on them."

Troopers said they can't remember anything like this happening in recent memory.

In the meantime, drivers are grateful no one was hurt.

"We're all still standing," Ertl said. "We're all still alive.”

Troopers said if anyone was in the area before the shooting and they saw anyone walking, carrying anything or acting weird, please, call 911.
