The rest of her life, however long or short, will be hell.
Her siblings are going to have nothing to do with her. She took away their parents. I would be surprised if they ever speak to her again.
No more homeschooling - she helped kill her mother/teacher (whether she's charged or not, she knows that.) She's going to have to go to public school - where everyone will stare and point. She will have NO friends, NO activities, nothing, and the whispers and pointing will follow her wherever she goes. Anybody who hangs around with her will do it just for the notoriety, she'll always wonder about that.
Even if she moves far away with distant cousins, the word will get out. And she would have trouble finding somebody to take her because they would always wonder if she might loose hell on THEIR home.
I predict a death from alcohol/drug abuse, or suicide, very soon.
And I'm sorry for her. She thought she was being so cool flouting her parents . . . and then reality reared its ugly, murderous, evil head.
Maybe the older brothers will have to take the kids.
