I was looking around on the internet to see if there would be any reason why the R's would want JBR's body found after 10 a.m. and by about 2 p.m.
I didn't find what I was looking for, but I did find this website: (Please note that it's a PDF file, so don't open it if you have problems with those!)

I'm going to try to post a few of the quotes I thought were really interesting in light of the JBR case:
1.
"If a body is moved before the onset of rigor then the joints will become
fixed in the new position in which the body is placed. For this reason, when a body is
found in a certain position with rigor mortis fully developed, it cannot be assumed that
the deceased necessarily died in that position."
2. (Following a data chart)
"In this series, rigor was complete in 14% of cases at 3 hours post mortem and this
percentage had risen to 72% at 6 hours and to 90% at 9 hours. By 12 hours post mortem
rigor was complete in 98% of cases. "
3.
"Onset is relatively more rapid in children and
the aged than in muscular young adults. It develops early and passes quickly in deaths
from septicaemia or from wasting diseases. It is delayed in asphyxial deaths, notably by
hanging or carbon monoxide poisoning, and also when death has been immediately
preceded by severe haemorrhage."
I think this raises some interesting possibilities, as follows:
1. Was the position JBR's body was found in, complete with wrist ligatures etc., really the position she died in? Or was this position made necessary because her body was initially hidden or moved before rigor had developed, making it necessary to create a scenario of the crime which accounted for her arms being above her head?
2. The data on the website I linked to analyzed several cases and found that in 98% of them rigor was complete by the time 12 hours had passed. When JBR's body was found, I think I read somewhere that rigor was complete. How long prior to 1 p.m. on the 26th was she killed?
3. I doubt the R's would know that rigor developed more quickly in children or might be delayed in the event of hemorrhage or asphyxia (both associated with her death). Either way, it's interesting that on the one hand, JBR's age might have sped up her body's rigor, or her manner of death might have delayed its onset, on the other hand.
I'm sure this has been covered before, but even though I'm not sure if it means anything, it seems interesting.
All along I've thought that the R's estimation of the passage of time on the 25th was weird. You leave a party around 8:30, deliver three packages while standing at the doorway and talking (for fifteen or twenty minutes at each house while your husband and kids sit in the car in the driveway with the motor running? Really?) and don't get home till nearly 10? But you're leaving on a plane at 7 a.m.? But you still take time to help your son put together a toy he got that morning? And you weren't finished packing? But no, nobody had a snack before bed? Especially not pineapple?
More and more I'm suspecting that JBR's tombstone records a moment of unintentional honesty on the part of the R's.
