It was roughly 8:30 p.m. when two deputies driving separate cars pulled over a vehicle with expired tabs near South 116th Place and 72nd Avenue South in Skyway.
As the deputies were questioning the driver, an unknown man walked by and opened fire, according to King County Sheriff John Urquhart.
"One of the deputies was up at the driver's window talking to him and somebody starting firing, probably at the car and not (the deputy)," Urquhart said.
Nobody was injured, but the car and a nearby apartment building were hit with gunfire. Urquhart said the shooter then ran away and jumped into what police believe was a black vehicle. The deputies did not return fire.
A neighbor was inside his apartment on his couch when the shots rang out.
"It was a constant, pow, pow, pow, pow, right behind each other," he said. "It was scary, to tell the truth. It was really scary."
Police have not released a description of the shooter or a possible motive. Several local jurisdictions are now searching the area for the gunman.
