You may be able to hire ocunsel to write letter to the parents offering to assist in finding programs fo the dughter. I fthey lock her out ther ein heat or cold, you may be able to report it as abuse. her screaming may not be a noise nuisance during th3e day, buy teh loud radio can be. Kansas City has noise decibel levels over which the parents might be cited for a disturbance.
Good luck
