Speaking to reporters hours after the shooting occurred, Portland police said they had identified another shooting victim, bringing the total of those injured to four.

The fourth teen, a 19-year-old girl, was grazed with a bullet on her foot and was treated and released at the scene, Portland Sgt. Pete Simpson said.

Meanwhile, a 16-year-old girl was in critical condition, and two males, aged 17 and 20, were listed in serious condition at Legacy Emanuel Health Center, Simpson said.

All of the victims were associated with Rosemary Anderson High School.

Oliviann Danley, 16, told The Oregonian she saw a boy run into the school, holding his coat open and yell "Oh my god, did I just get shot?"

Another student, 17-year-old Sierra Smith, told the paper she was in class when the shooting occurred and later saw a bloody scene inside the school as one of the male victims sought assistance.

"He was laying on the ground," Sierra said. "He had blood coming out of his stomach."
