Pierce County sheriff’s deputies are seeking a fourth person in connection to the shooting Tuesday afternoon outside Graham-Kapowsin High School.
The male was in the back seat of the green Chevrolet Impala in which the shooters fled the scene, sheriff’s spokesman Ed Troyer said. That car was impounded Tuesday night.
Two of the suspects in the shooting have been arrested, Troyer said, including the driver of the car. The boys had their first appearance in Pierce County Juvenile Court on Wednesday. It has not been determined whether they will be charged as juveniles or adults.
One more person wanted in connection with the shooting remains at large.
The two victims in the shooting suffered non-life-threatening injuries, officials have said.
Anyone with information about either person who is at large is asked to contact Tacoma-Pierce County Crime Stoppers at 800-222-TIPS (8477).
