Qzukk's Journal: Perfect Crime?

Let's say someone were to call the cops and cry about their daughter being kidnapped and they saw the guy and the car he jumped into, gave the cops the license plate number, and gets an amber alert issued. The guy gets caught and claims to have no clue what's going on, the caller confronts the kidnapper, crying "just tell me where you buried her body" and collapses in a fit of hysteria.

Would anyone think to demand proof that the daughter existed in the first place?

An interesting twist on the various recent crimes where people had made up a false attacker in order to cover up their own misdeed (or in the case of the cop who shot himself, because he's apparently crazy). Most of those eventually broke down under scrutiny or through the criminal's own guilt. But if someone made up a false victim, would the scrutiny fall in the right place?

Yes.

They might make an initial arrest, but they do do thorough investigations and the fact that you don't actually have a daughter would get noticed. And you would likely get prosecuted for lying to the police.
