The Twine of Linda's Fingernails

Sisal is a term used in the industry to indicate that it's a natural fiber. It may come from a specific type of plant, but that's something that I'm not aware of. We also know that this twine has shown up under Linda's fingernails. So I don't know if the killer tried to bind her to the tree. But the way those branches are formed, I can easily see twine just naturally getting caught up in it.
