This was an interesting episode. It looks like the key went to Richmond's office. It could have been any of his staff who had the key. Where I worked, my ID badge could be a key and had my photo on it. I guess this did not have a name or photo. I don't think Richmond did it. I think he was where he said he was but one of his staff could of done it. I loved the fact that the mafia guy is now dead.
