Here is what puzzles me. In response to the theories that her throat was slit first to prevent her from screaming. The reason I’m going to disagree is because both major (only) blood supplies in her throat were severed. She would have bled out too quickly and died within what, seconds to a couple minutes at most? She didn’t though.
She was alive for most, if not, nearly all of the attack. I think her throat was done last. Or she had a superficial throat cut at first, then they went back later to cut deeper. Sounds gross, and I’m sorry, but if they did that damage right off the bat, she wouldn’t have been able to hemorrhage out from the other wounds, which she did. Because she stayed alive for so long, and that wouldn’t have been possible with a severed carotid artery.
