I would bring it up. I've been through similar with people stealing out of my wallets and when I found out I raised hell, but yes I got shafted even though I was right.

Doesn't matter. I don't want that shit in my life. It's a hard call, but up to you in the end if you want the ensuing shit storm for what is right. They'll likely deny it, but maybe you can ask your cousin's (the parents) if they noticed a new nano around and what colour it was. Then boom. Proof, then go after them.

It's not okay. Sorry this went down.
