Two 17-year-old boys were shot behind the King County Aquatic Center in Federal Way Wednesday morning after a fight.
A Federal Way Police Department spokesperson says the teens were taken to Harborview Medical Center with serious injuries.
Police say they have encountered the victims in the past and that they don't believe the shooting was random.
Two persons of interest, both 18 from Federal Way, are in custody.
