My parents told the elders, but never informed the authorities. Afterwards, they pretended like the whole situation never happened.
I know it would've been really hard to go through the whole mess with a legal case and everything, but I guess the upside would've been access to therapy (if my parents hadn't been so mistrustful of worldly psychiatrists). Even now, I really don't know what I would've liked them to do, but I've still never forgiven them for how they acted.
