Officers were at the scene investigating a car crash when they heard gunshots. They searched the area and found a 19-year-old woman and a 19-year-old man with multiple gunshot wounds.
Deputy police chief Nick Metz said the two teens were in car when someone in another car opened fire on them. After the shooting, Metz said the victims went off the road and nearly crashed into a nearby car wash.
According to the Seattle Fire Department, the woman was shot in the head and arm. The man was shot in the arm and leg.
Both victims were taken to Harborview Medical Center in stable condition. Medics say both were alert and oriented following the shooting.
