Baileigh Karam has not been seen or heard from by her mother since January 11, the day of the fight, CBS affiliate KFMB reports. 

In the video, a group of students can be seen surrounding wo girls, recording the brawl on cell phone cameras, but nobody steps in to help or stop the punches.

"The other girl just punched her over and over and over, while my daughter was saying 'stop, stop.' And the crowd was egging it on," said Karen Karam.

According to the station, the mother says some students later posted videos of the fight on Facebook, where other teenagers made comments, many of them negative.

"It's a very ugly world sometimes on Facebook," Karam said, "I know my daughter's out there reading all of those comments. And I know she's heartbroken. And I know she's humiliated in front of her high school."

The missing teen's mother says her daughter may be traveling with another teen girl, KFMB reports. Karam says her daughter exchanged several text messages saying she wanted to be left alone by her mother and by Carlsbad Police, whose juvenile detective unit is investigating the fight.

Anyone with information on Baileigh's location is asked to contact Carlsbad Police.
