I’ll just mention this as a possibility: given the description of brazen thefts pointing to hotel staff in the comments by guests, perhaps Campos and maybe Schuck as well are part of a ring of hotel staff that steals from hotel rooms. One guy notices when guests have left the room, and uses his master key to slip in and have a quick look for obvious valuables, while someone else acts as lookout.
This might explain why the story has shifted so much as to what Campos was doing and why the low profile and no interviews. We didn’t even know about the existence of the maintenance guy for a week.
I remember the maintenance man being mentioned the night it happened
I believe there is a record kept every time a Hotel Room Door is unlocked with a Key in these big Casino Hotels.
There is more going on behind the scenes than is being disclosed, but I am not buying in to the Grassy Knoll conspiracies that keep popping up.
