'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,' Karam's mother, Karen Karam, told CBS8.

The fight was over a boy, she said.

'I don't know where she is,' Karam said. ' I just want to get her home. We just need her here. We need to know she's healthy and safe.' 

Karam said she had waed the school that her daughter was being bullied. School officials spoke to each of the girls before the fight broke out. The attacker has not been named. 

Devastated: '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 Karam's mother, Karen Karam

'A girl and her boyfriend had broken up and Baileigh and the other boy started liking each other and had a connection, and the other girl clearly didn't like that,' Karam told KFMB news. 'Then the threats started coming.'

Students 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.'

This is the high school in Carlsbad, Califoia where Baileigh was bullied and where the attack took place
