I donīt know if this has been mentioned, just because I havenīt played the full episode yet and donīt want to read the spoilers. So, feel free to remove this if itīs been already mentioned.
Anyway, did you check out the old case file at Sam & Maxīs office? It has a date on it. Check it out. "That case was particularly gruesome." Luckily now we can laugh at things like this, thanks to Telltale.
