I’m thinking about a newspaper article I saw earlier this year, about a teenager named Ray who was found in Germany; he claims his father raised him in the woods, so he has no knowledge of modern life. He said his father died. It was discovered that his story was a hoax, but what’s relevant here is how the authorities handled the case. In addition to trying to determine his identity, they gave him physical and psychological tests to find out if he was mentally stable. They didn’t immediately believe him but neither did they immediately assume he was lying or insane.
If Bae’s lucky, this is what happened to him; being a clever kid, he probably would’ve figured out soon enough how to convince authorities he was sane and truthful, in which case he probably would’ve been placed in the foster system instead of some sort of institution.
