No. Unless you still have the original box with the serial number and a receipt, it's basically going to be your word against his. Even then, you'd still need to know where it is, and have the cops get it.
Sorry to say, but it sounds like your son is going to have to learn the annoying life lesson that sometimes bad things happen and there's nothing you can do about it.
My son had his DSI stolen from the house about three weeks ago from a friend of a friend and when confronted he denied steeling it. So my question is does it have some kind of like gps or anything other ways of finding it. He had the wireless internet set up on it and I registered it with nintendo but I would really like some help because it is something he and I saved up for and bought when first came out. HELP!
