The drama unfolded shortly after 7 a.m. when deputies received 911 calls about a man running his pickup into the building's outpatient entrance, said Detective Jason Stanley of the King County Sheriff's Office.
After crashing through the entrance, the suspect drove into the lobby there. He rammed the building repeatedly as he backed up and drove forward to get back out of the building, witnesses said.
As the first deputy arrived on scene at the Highline Medical Center, the suspect tried to ram his patrol car and yelled for the deputy to kill him. The suspect then sped off in his pickup and the deputy followed him.
During the pursuit that followed, the suspect rammed the deputy's patrol car and also hit a light pole near the Burien branch of the King County Library system.
The deputy was finally able to stop the pickup using an intervention maneuver that brought the pickup to a stop, Stanley said.
Then two other deputies pinned the car into a pole at the intersection of SW 146th Street and 4th Avenue SW, where the pursuit ended. The suspect was pepper-sprayed and taken into custody with minor injuries.
A King County sheriff's official said law enforcement personnel are familiar with the man and that he suffers from suspected mental health issues. There were reports that the man had previously been involuntarily committed at the Highline Medical Center a few days earlier.
The deputy whose vehicle was rammed by the suspect suffered minor pain from the collision.
The outpatient entrance and lobby at Highline Medical Center sustained significant damage, Stanley said. The entrance is now closed, with all the windows and glass broken out.
Nobody was injured at Highline Medical Center, and the hospital continues to operate without any effects on services. Patients who use the outpatient entrance are directed to enter the hospital through the emergency room for information on where to receive their care.
