The game is possibly bugged, or just a 3rd piece of evidence hasn't been found? I got the Evidence in the jacket and the Glass shard, but Hogan (I presume) is very much bugged and I'd presume evidence or needed information to leave the apartment building is needed from Hogan, but the game is bugged and thinks he's always talking to the landlord even when he's done the questioning and is by the exit door, the game invisibly thinks his location is on the Left side of the room by the landlord still. Sort of an unfortunate Softcap lock on the game (If my presumption is right about Hogan holding the info I need to proceed).
What makes me ponder is why no one else who's already recorded the game or played it - has mentioned this bug. Otherwise, will have an incomplete Let's Play out soon.
