 The victims are students at Rosemary Anderson High School or in related job training programs, police Sgt. Pete Simpson said. A 16-year-old girl was in critical condition, and two males — ages 17 and 20 — were in serious condition, police said. A fourth person — a 19-year-old woman — was grazed by a bullet but not hospitalized. 
 
 The shooting was reported after noon and happened at a street corner outside the school, Simpson said. 
 
 Witnesses told police there may have been a dispute outside the school, but police said they didn't know who was involved. 
 
 "We don't know what led up to the shooting," Simpson said. "There was some kind of dispute." 
 
 The assailant and two other people fled, and the wounded students went to the school for help, he said. 
 
 A nearby high school and community college were put on lockdown. 
 
 Preliminary information suggests the shooter has gang ties, Simpson said. The Police Bureau's gang unit was deployed in the investigation. 
 
 Sierra Smith, a 17-year-old student, told The Oregonian she saw one of the male victims being helped by a teacher inside the school. 
 
 "He was laying on the ground. He had blood coming out of his stomach," she said. "It was scary." 
 
 Another student, Oliviann Danley, 16, told the newspaper she saw a boy run into the school and yell, "Oh my god, did I just get shot?" 
 
 Rosemary Anderson High School serves at-risk students who were expelled or dropped out, or who are homeless or single parents. According to the school's website, 190 students annually are enrolled at the north Portland location. The school also has a second location in Gresham. 
 
 Gang violence in Portland isn't a new phenomenon. Some of the violence occurs between rival gangs, but bystanders have also been hurt. 
 
 "We've made a lot of progress in addressing the gang problem, but we haven't eradicated it," Mayor Charlie Hales said after shooting Friday. "Today's really a sad reminder that it's still with us." 
 
 Portland police have said they saw a spike in gang crime this summer and have complained they don't have adequate resources to address the problem. Recent violence includes a man killed in a drive-by-shooting in June and another man killed in a separate shooting. A 5-year-old boy also was shot in the leg while playing at an apartment complex. 
 
 A Multnomah County report on gang activity released in June said crime in the county that includes Portland actually decreased from 2005 to 2012. As inner-city Portland gentrifies, the report said, criminal activity is shifting from northern neighborhoods to areas farther east, including the city of Gresham. 
 
 The report identified at least 133 active gangs in the county. 
 
 Dani Gonzales, 64, has lived in the neighborhood of Friday's shooting for 25 years and said it's generally safe but there has always been some gang activity. 
 
 "Kids just get silly and get crazy ideas. I don't know what goes on in their heads," Gonzales said. 
 
 There was another school shooting in the Portland area in June, but it was not gang-related. A freshman killed another boy in a locker room and a bullet grazed a teacher before the shooter went into a bathroom and died from a self-inflicted gunshot, police said.

Simpson said that the shooters may have gang affiliations, but it's unknown whether that had anything to do with the dispute or the shooting, and it doesn't follow that the victims had anything to do with gangs. "They are victims," Simpson said. 
 
 Police say they believe there was one shooter accompanied by two others. The suspects fled on foot, Simpson said, heading north on Borthwick and east on Killingsworth. They left the scene quickly and it's unknown whether they had a car nearby. All are at large.

 "I'm just confused. All of these kids getting shot and killed. It doesn't make any sense," Shawn Zimmers said. "It's not like it was when we were kids." 
 
 Ashley Zimmers, 17, and Octavia Heaton, 15, two of Taylor's cousins, also waited outside the hospital. The girls, who do not attend Rosemary Anderson, said they were not allowed to enter the hospital to see their cousin. 
 
 The girls said they had heard that Taylor had been shot in the chest and the side. 
 
 "This is crazy, but not surprising" given the recent string of shootings nationally, Ashley Zimmers said. "This hits too close to home."

Rosemary Anderson is a nonprofit school that PPS Connect contracts with. Of the 290 Rosemary system students, 216 come from PPS Connect. Students in the program can earn a GED or modified diploma.

 Amid all the confusion, both had heard that Labraye suffered wounds in different parts of his body. 
 
 "When I first got the phone call," Tanisha Franklin said, "I just started praying, 'Please let him be all right.'" 
 
 "This is just crazy," she said. "I work at a school and with all these shootings, I get more and more scared every day." 
 
 2:26 p.m.: Jacal Hill, a 17-year-old senior, said she was among a mass of students lined up waiting for the school doors to unlock for lunch. Once outside, she had just turned the street corner when she said she heard shots behind her. Scared, she hid behind a car. Now safe, she said, her thoughts are of her friends.

"Everyone was scared, she said.

 -- The Oregonian
– A gunman opened fire today on several young people outside an alternative high school in Portland, Oregon, wounding four and fleeing on foot with two other people, police tell the AP. The victims are all students at Rosemary Anderson High School or in affiliated job programs: a 16-year-old girl in critical condition; two males, 17 and 20, in serious condition; a 20-year-old male in serious condition; and a 19-year-old female who was lightly grazed and treated on the scene. The father of a fifth victim, a 16-year-old girl, tells the Oregonian that his daughter is in surgery. Police suspect the shooting is gang-related and say a dispute may have erupted before the bullets started flying. Eye-witness accounts are piecemeal so far, with one student saying she saw a male victim lying on the ground with "blood coming out of his stomach. It was scary." Another says a male student ran into the school holding open his coat and yelling, "Oh my god, did I just get shot?" Friends and family waiting outside the Legacy Emanuel Health Center, where victims are in surgery, are talking about the shock of gun violence. "It doesn't make any sense," says the 40-year-old aunt of a victim. "It's not like it was when we were kids." Portland police say gang violence rose over the summer but law enforcement lacks resources to deal with it. Rosemary Anderson High School serves students from troubled backgrounds, including those who are homeless, have single parents, dropped out, or were expelled.
