According to the student, she was walking on campus with two friends. They heard someone call her name but ignored the person who said it.
That someone called her name again, and they were then approached by three girls. Then, she was told that one of the three girls was going to assault her.
"I was like, 'Well, I'm not going to fight, because I don't want to get in trouble,'" said the 13-year-old.
As she tried to walk around the group, video captured on a cellphone shows another female student walking up to her, grabbing her, then striking her and knocking her to the ground.
The perpetrator continues to pummel the victim, throwing punches to her head and face. A crowd of students gathers and voices can be heard, with some yelling, "Beat her head on the ground."
The victim tries to cover her face from the barrage of blows.
The perpetrator eventually relents and starts to walk away, but campus security guards catch up with her.
The mother of the victim is upset at the disciplinary measures she says were taken. Shugie Rubio said the principal told her the aggressor would be expelled. Not enough, feels Rubio.
"If any other person would do this outside of school, I would hope it would not be handled like that," said Rubio.
Rubio insisted on filing a criminal complaint with the Kern County Sheriff's Office. A report was taken and depending on the findings of the investigation, may or may not be forwarded to the Kern County Juvenile Probation Department.
From there, it will be reviewed and then it may be forwarded to the Kern County District Attorney's Office for possible prosecution.
Rubio said filing a complaint was necessary to stop future incidents such as what happened to her daughter from occurring again.
"I just wish these kids could see the seriousness of it," said Rubio.
Her daughter said she feels humiliated by what happened. The video has been posted on Facebook, complete with snide remarks from students.
The daughter is not returning to Curran, opting instead for independent study until the end of the school year.
"I just don't want to go to Curran. I'm already humiliated," she said.
The mother has another fight on her hands. She said she has been trying to get her daughter transferred out of Curran Middle School but has been unsuccessful.
