Please note the post with a link proving the FBI was involved. But I do understand some things have been repeated so much that aren't true...like Rebecca's clothes being missing (they were folded on the bed), that Rebecca was knocked out (the bruises on her head would not have knocked out a fly they were so small), that Rebecca was the only one there when Max was accidented (here daughter'sister was there with her), her hands were bound (she was holding the end in her dead cold hand proving SHE bound herself), she was gagged (could have sppit it out any time), etc. etc. etc. etc. ect.
BBM. I'm impressed with your knowledge of this case. I've forgotten many of the details.
The point of doing a "tug hitch" is because just one end can be pulled to undo it. I wonder if RZ was hoping she would be found in time but she didn't have the strength to undo it herself?
