PORTLAND, Ore. — Police say a shooting outside a Portland, Oregon, high school that hospitalized three people may have been preceded by an argument, and the shooter was accompanied by two others when he ran from the scene.
Police said earlier that they believe the shooter has gang ties.
Police said at a news conference Friday afternoon that all three people who were hospitalized are affiliated with the school.
A 16-year-old girl is in critical condition, and two males — one age 17 and the other 20 — were in serious condition.
Police say a fourth person — a 19-year-old woman — was grazed by a bullet but not hospitalized.
