They said the fight lasted for less than two minutes and was broken up by other students in the bathroom as well as a staff member supervising outside of the bathroom.Once the fight had been broken up, district officials said all students involved walked under their own power to the assistant principal's office and the nurse's office.| MORE | Parents of Owasso High School student who died correct errors of misidentifying their childBody camera video from an Owasso Police officer showed Benedict telling their account of what happened, saying they had finished stacking chairs in the lunch room and went to the bathroom. A group of freshmen also were in the bathroom when Benedict told the officer "I was talking with my friends, they were talking with their friends. And we were laughing, and they had said something like, 'Why do they laugh like that?' And they were talking about us in front of us."Benedict then said they poured water from a water bottle on the girls, "and all three of them came at me.""They came at me, they grabbed on my hair. I grabbed on them. I threw one of them into a paper towel dispenser, and then they got my legs out from under me," Benedict said. "Got me on the ground and started beating the (expletive) out of me. And then my friends tried to jump in and help, but I'm not sure. I blacked out."Security footage from Owasso High School showed that everyone involved in the fight was able to walk to the assistant principal's and nurse's offices under their own power.Why didn't the school call police?

"And I will say for what it's worth, (name redacted), I've worked with her for five years. She's typically spot on, meaning the one who was with us in our conversation. She's one of the best in that school of handling. If I was a betting person, I would venture to say that there was something else a little more pressing that was going on – not that this was not. But I think, like anything, maybe it was a little overwhelming, maybe she had something else going on and it just slipped her mind probably. Because as soon as I sent her a text message that said, 'Do you know anything about a fight at school? Because I'm going to the ER,' and she was, 'Oh my gosh. Yes. Can I call you?'" The officer said the administrator said in the text exchange that there was an incident at the school and that they'd discuss it the following day.None of the statements from Owasso police or the school district addressed why police weren't called after the fight took place.The Owasso Police Department's investigationAccording to police, officers were called around 3:30 p.m. on Feb. 7 to Bailey Medical Center by the parent of a 16-year-old female Owasso High School student.
