So, could be a hoax. Or, could be the boy wasn't in it at all and ran off. Or, could be the boy fell out.
None are good things, but I sure as hell hope it isn't the last one.
I'm guessing the kid untethered it, got scared, and is hiding. He probably is terrified his parents are going to punish him.
Or, someone abducted him and used the balloon as a diversion.
