Locked Room: Motel

You've got an old friend Mr Thompson, who came to the city to attend a conference. Right after that, you went to have a dinner together. You haven't been seeing each other for a long time so you wanted to catch up. At the end of the night you went home, and he went back to his motel room. As of this morning you haven't been able to reach him at all, and that is very unusual, to say the least. Therefore you have made a small investigation and you found out that Mr. Thompson is not the only one who have disappeared from this particular motel room. You thought that you would pay a visit to your friend, but at the reception they handled your request quite suspiciously, they gave you only an hour before the staff has to do the full clean. It feels like that you have never had to be this precise about the hour you've got. Look around in the room while you can, and find Mr. Thompson!
