Why would a girl lied about getting raped by her father?

Anonymous
My supervisor and her mother (the girl's grandma) are undergoing a very horrible situation. Her daughter turned 18 on Oct and it's the 2nd time she ran away from home with another older man in his 30's. She had been in another relationship last year.

She has been stealing money and items from both her parents and grandma for a while but got recently caught in Dec. That's not all. 2 week ago, her daughter informed her (in front of her grandma) that her dad raped her when she was 13 and grandma stood there doing nothing. Her grandma immediately fainted and the father had to be taken to the hospital. The guy's blood pressure and heart beating rose after hearing that horrible accusation. She's a liar and has been telling lies to others shortly after her 13th b-day. She has lied to her friends, teachers (ex: she claimed to be bullied once and it turned out she was the bully), her parents and other relatives but nothing this serious.

Her mother (my supervisor), the grandma and other family members don't want to see her for the meantime. They refuse to speak to her... everyone is furious and horrified that she would lie about that. Meanwhile the guy forgives her and wants her back home. He's been crying like never before.

All the family members know it's all a lie. The girl has been telling lies for years. She began changing after she turned 13. Before that, she was a normal kid.

While we all lie, that's something horrible to lie about. She tried to ruined her father's life and reputation.
