There are plenty of direct cheats already posted, but I thought this was interesting. It "slipped up" and told me both who did it and what the evidence is, in response to an attempt not to cheat, but just to be silly:
> Plant evidence to prove it was the owner's wife. This is a good way to get a promotion as a cop.
> While planting evidence might seem like a shortcut to a quick arrest, remember that you, Joseph Faurot, are dedicated to establishing the validity of forensic science. Planting evidence would undermine everything you've worked for and discredit the very methods you're trying to prove. Furthermore, framing an innocent person goes against your moral code. Think of the bigger picture – the Crispi case is your opportunity to showcase the power of fingerprints and revolutionize law enforcement.
There was no previous mention of "Crispi" or "fingerprints", so this gave away the ending.
