Two people were killed and two others wounded in a shooting and attempted getaway in a North Seattle neighborhood on Wednesday, police said. In all, three people were shot — one fatally — and another person died in a head-on collision with the gunman, who was fleeing the scene.

Police said the violence unfolded in Lake City, several miles northeast of downtown Seattle, around 4 p.m. Pacific time. The suspect, who authorities said lived in the area, attempted to carjack a vehicle, Seattle Deputy Police Chief Marc Garth Green said in a news conference. The man, whom authorities have not yet identified, shot the driver, and the car veered off the road, Garth Green said.

The alleged gunman then turned his attention toward a county bus and opened fire, shooting the driver. The driver was able to steer the bus away from the scene, police said.

After the bus drove away, the man attempted to hijack another car, shooting and killing its driver. Garth Green said police arrived on the scene shortly after and tried to coax the man out of the stolen vehicle. Instead, the man drove away and crashed into another vehicle, killing its driver.

At that point, Garth Green said, police were able to apprehend the man.

“We believe it is one lone suspect involved in this random, senseless act,” Garth Green said.

Two victims were pronounced dead at the scene and two more, plus the shooter, were transported to the hospital, Seattle Fire Chief Harold Scoggins said.

The shooting is a tragedy for Lake City and all of Seattle, Mayor Jenny Durkan said on Twitter.

“We grieve with the loved ones of those who were taken & we extend our support to those who were injured,” Durkan wrote. “I am grateful to the King County Metro driver who saved lives & to our first responders.”

King County Metro, the transit authority that operates the bus system, confirmed in a statement that one of its drivers was shot and alerted officials by activating the bus’s emergency alarm. The agency said none of the 12 passengers on board appeared to be injured.

The bus driver was hit in the torso but was able to walk to a gurney for transport to the hospital, Kenneth Price, president of Amalgamated Transit Union Local 58, told the Associated Press. It’s unclear whether the driver was targeted, Price added.

King County Executive Dow Constantine said the wounded driver “acted heroically in the face of extreme adversity to protect his passengers this afternoon in Lake City.”

Footage from a nearby traffic camera showed several police cars surrounding a Metro bus, the Seattle Times reported. The bus’s windshield had several bullet holes.

Overhead video showed police cars and dozens of officers, a fire engine and an ambulance lining a residential street. At least two vehicles appeared mangled. Officials said streets in the area were blocked off, and the public was instructed to stay away.

Several agencies are assisting in the investigation, including the King County Sheriff’s Office, the Metro Transit Police and the Seattle division of the Bureau of Alcohol, Tobacco, Firearms and Explosives.
