The only proof I have of the prosecutor's decision is an email.
The entire thing happened with the smallest paper trail you could ever imagine. I was never informed of my ex-parents' request. All I did was someday get a summon to meet with the social workers, and that letter included no reference to a request of conservatorship, or any legal text of any kind. For months I wasn't even told what it was about, it's only heavy googling based on allusions that led me to understand.
