Ha! This is awesome. I love experiments!
I’m so glad you posted this, as it seems to show that there’s more than one way he could have done it, and come out unscathed.
It’s scary that it’s so easy, and more so when you factor in that she was likely caught unaware, and he was incredibly motivated to kill.
It really is scary! I was completely prepared, and my husband is stocky and muscular while I have chronic pain issues so I was on guard. And I was still surprised how fast I was incapacitated without a chance to fight back. All he had to do was get my arms pinned somehow and it was over.
I can only imagine how Shanann must have felt. It also made me feel a tiny bit of comfort, if there's any to be had, that I sincerely doubt she knew he killed the girls or that they were first. I think he needed complete control, and it would have been too much of a wild card because fear and rage give a lot of extra adrenaline strength he wouldn't have wanted her to have. Nor would he have wanted her to be on guard and ready to fight back.
All JMO again.
