Read this info on a blog somewhere.
The speculation was that some unknown person(s) escaped upwards rather than downwards.
So much hinges on the narrative surrounding the security guard. I can’t figure out why the shooter didn’t just finish him off.
He is the guy who offered the NYC millions after 911 and Rudy turned it down.
Good find on your part. Good research to be commended.
Adds an entirely new element to this mystery.
I don't know you, but many kudos for your astute research.
