IMO, if JR INNOCENTLY discovered JB's body in WC at 11:00am then he would let LE, Patsy and all other know about immidietly!!! But he didn't!!! So, the reasons why he waits until 1:00pm to 'rediscover' her agan are: he knew what happens and he was busy to tide-up the 'staging' in anticipation for the next move.
I have no doubts that JR new where JB is prior 1:00pm. For me, the most important proof of JR knowledge of the hiddend JB body at 11:00am is based on the following.
Two people have been in the basement twice: FW and JR.
- FW was by himself early in morning, he've been in Train room and opened WC;
- After him, JR was in basement (claiming later that he saw open window and luggage). Meaning, he was in Train room. However, he never mentioned that he opened WC;
- Now, near 1:00pm, both of them repeating the same path LEADING by JR. And where he goes? He starts with Train room and next WC.
IMO, JR (unconsciously or deliberately?) repeats the same path in the presence of the witness. JR's path at 1:00pm from Train room to WC tells me that JR had open WC at 11:00am as well.
