PITTSBURGH (AP) -- Three Pittsburgh high school students heading to their vehicle after classes ended were shot Wednesday afternoon, and police investigating whether the shooting stemmed from a drug-related dispute had six people in custody for questioning, school and police officials said.
The victims were shot outside Brashear High School as they walked to a vehicle they'd all taken to school earlier in the day, school district spokeswoman Ebony Pugh said. Nearby residents said they heard seven or eight shots.
The wounds of the victims, all boys, appeared to be non-life-threatening, both Pugh and police spokeswoman Diane Richard said, though their descriptions of the wounds differed slightly. Pugh said two students were grazed in the head and one was shot in both the foot and arm. Richard said one was grazed in the neck and shoulder, but not the head.
Police believe the shooting might stem from a drug-related fight between some students last month, Richard said. Neither she nor school district officials immediately provided more details.
Six people were brought in for questioning, Pittsburgh public safety director Michael Huss said about two hours after the shooting. Police said some were current or former students, but Richard wouldn't say whether any were considered suspects or necessarily going to be charged.
"There are no arrests at this time, though we have some folks of interest," Huss said. "Our police need the time to do a thorough job here and we need to give them that time."
Acting police Chief Regina McDonald confirmed, however, that police had stopped searching for gunmen, and Huss said, "The situation is under control."
None of the victims immediately spoke or cooperated with police, Richard said. All were listed in good to stable condition at city hospitals, she said. Two are 17 and one is 16.
The student who was shot in the head was found inside the school, though that's because he "made his way back to the school, and was pulled back inside by one of the administrators," Richard said.
She stressed, "There was no shooting at Brashear school. ... The shooting did not happen in the school."
Brashear, with about 1,400 students in grades nine through 12 about two miles south of downtown, was locked down briefly, though students were released to their parents about 90 minutes after the shooting.
According to a Safe Schools report filed annually with the state, Brashear had 97 incidents involving 138 people during the 2012-13 school year, but none resulted in a police response or arrests. Forty-seven students were disciplined for fighting, the report said.
