FORT GIBSON, Okla. — Four students at a rural middle school were shot this morning and a middle school student was taken into custody.Superintendent Steve Wilmoth said students were gathered outside before the 8 a.m. start of classes. "Another student just walked up and opened fire on them," he said. "From what I know at this point it seems to be a random thing."Tyra Palmer, a spokeswoman at Tulsa Regional Medical Center, said a 12-year-old boy was in fair condition there with gunshot wounds to both arms. A 12-year-old girl was in fair condition at St. Francis Hospital in Tulsa with a gunshot wound to the cheek, said hospital spokeswoman Melissa Bogle.Muskogee Regional Medical Center said two 13-year-old boys were brought there, one with a gunshot wound to the forearm and another to the leg.Justine Hurst, a 13-year-old eighth-grader, stood outside the school with her father, Jim, hours after the shooting. She said she knew two of the victims and the alleged shooter."He seemed like a really nice person," she said, identifying the shooter as a seventh-grader in her school. "He had a lot of friends."Authorities offered no details about the suspect except to say he was middle-school aged.Justine arrived at the school just after the shooting happened, as students were being rushed inside into the school cafeteria. She said backpacks lay strewn everywhere."Everyone was screaming. Everyone was crying."She said some of the children thought the gunfire was the firecrackers left over from Saturday's football game when Fort Gibson played Weatherford in a state high school championship game.The windows of the school were still painted with signs from the game, including "We're cheering for you." Fort Gibson lost 46-0 to Weatherford.Lt. Jack Mike, a warden at the Muskogee County Jail, said officers at first thought the frantic 911 call about the shooting was a hoax. The first call came from a student about 7:45 a.m. An adult made the second call, and Wilmoth said help was at the school in a matter of minutes.Fort Gibson is a town of about 3,500 about 50 miles southeast of Tulsa. About 450 students attend the middle school.Wilmoth described Fort Gibson as a close-knit community.A school official said all of the district's 1,850 students would be released early today because of the shooting.
