My question involves child abuse or neglect in the State of: Kentucky/Georgia
I currently reside in Georgia and my sister(I'll call her Zoey), dad, and stepmother (also my sister's stepmother; I'll call her Maria) reside in Kentucky. Am I correct in thinking that I would need to follow Kentucky laws then if I were to do anything?
I've asked a couple of people about this and haven't gotten much help. Most people say I can't really do anything. That may be true, but I keep asking anyways with the hope something new will pop up.
Zoey turned 14 this December. There have been small amounts of physical abuse, but they tend to be stretched out. Mostly it's mental. For instance, Zoey didn't curl her hair according to Maria's standards, so Maria cut her hair really short (it actually looks like a mullet). Now Maria continues to threaten to shave Zoey's head if she doesn't curl that right. She makes Zoey wear guy clothes and clothes that are too big for her so that people actually think that she is a guy.
Maria is very controlling in everything. So that if Zoey misses cleaning a spot on the toilet, she is grounded for a month or more. Essentially, there are few days when she is not actually grounded.
Sometimes, after Maria takes a bath, she'll have Zoey take a bath in the same water she just took one in.
I could go on and on, but it's just a lot of mental abuse. I honestly don't know how long it will be before she does something on her own like run away. I'd like to be able to remove her from that situation before she does something like that and ends up getting hurt or receiving repercusions for those actions from Maria.
I'm willing to take care of her if possible, but I also know other older family member who would be willing to take care of her as well. If anyone has any ideas or suggestions, I'd really appreciate it.
