if there were calls much earlier (like an hour or more) than the alleged wake-up time and the 911 call that would be incredibly sus whoever it's to
i've entertained the possibility (on the assumption JR was not involved in the murder or coverup, at least not yet as of 12/26) that he called someone who can help with hostage negotations, either before the 911 call or at least before the body was discovered. an actual negotiator, or a point of contact who could help him get one, etc. it seems likely he would have had some training or information on what to do in such a situation, given his job. if he was out of the loop and took the ransom note at face value, that would make sense.
also (or maybe overlapping) a possibility he called someone at LM and/or the pentagon, as required by a company policy or even a law. i assume he had a clearance for his job, and i am guessing he had access to sensitive stuff. aiui, if you're in that kind of position, the government wants to know when someone has leverage over you. debts, assets, side jobs, infidelity, embarassing secrets... anything like that would concern me if i were responsible for maintaining secrecy.
the possibility never occurred to me that the ransom note, by purporting to be from someone who took JBR hostage, triggered corporate and/or legal requirements and procedures, and it opens up a whole bunch of new theories i had never thought of, and i feel like john nash scribbling red circles on maps and connecting them with pieces of string. was the note written with that goal in mind? did it happen accidentally (e.g., if PR wrote the note and JR wasn't involved)? but does it somehow explain the parents never pointing the finger at each other? ... this is so potentially disruptive to my prevailing theories on the case that i almost wish it hadn't been pointed out to me, lol.
