sounds to me like they will all be biding their time until she is 18 ( unless her family goes ahead and kicks her out for good.)
here is a story about abuse in a witness home. The dad was an Elder. There were 2 children in the home. The Family took in foster children through the welfare system temporarily until more permanent placement for the fostered kids who were neglected or abused. So the boy knew the welfare would step in in cases of abuse...he went to the welfare and reported his parents for abuse and he was removed and allowed to go and live with his grandparents. He never returned to the family home. For years the grandparents weren't spoken to by this elder because they had allowed the son to live with them.
