I honestly don't think that her mother or anyone in her family has anything to do with this case... but it's very typical of North America to argue and then run away as if that would solve things... knowing that North America is very dangerous, there are a lot of networks of child and adult thieves, serial killers, psychopathic people, etc... but in this case the friends that her mother didn't approve of were the culprits... someone who was a drug addict or an alcoholic took her somewhere, God knows what they did to her... little girl, I hope that wherever you are, you're better and happy...
whatever it is
rest in peace
