The rich really are different from you and me.

Single guy, wealthy, never married, lover overseas, was in possession of explosive agents as well as many weapons, put up cameras, in VEGAS...
There are many possibilities, but my 1st guess for the 2nd guest is a hooker. Receipt is on the 27th, I think - guns probably still stashed or not in room.
I’ll bet LE is searching high and low for clues on whoever the 2nd guest might be...
