I believe she was murdered for a number of reasons - mostly based on how she was tied up.
I think LE did a great injustice by creating the video showing a woman tying her own hands with ROPE to show how Rebecca could have committed suicide.
However, she was tied with ELECTRICAL CORDS, not rope. Show me a video of how a woman can tie herself tightly with electrical cords instead of rope, and I might reconsider....
