Glad you mentioned Mandalay Bay. That one has been rattling around in my head also.
I bounce back and forth between “We don’t know anything because there is literally nothing to know. Just a random nutjob” and “We don’t know anything because authorities think the full story would be too explosive/embarrassing/whatever and don’t dare let it out”.
Which brings to mind the thought that my tendency toward suspicion in such matters only went up by about 8,000,000% when Jeffrey Epstein “killed himself”…while the guards were asleep at the switch, and the security cameras malfunctioned, etc, etc, etc.
