I think it is possible that KL had met AA before. I think it is very possible that she was not afraid of him because they had met previously. Their arrangement may have included things like submission--hence, meet me at the park because that is what I want, turning off the phone immediately and possibly even handcuffing as part of the encounter. It may have turned deadly after the encounter at the house. If he had her tied up, he could have gone to get a weapon with no issue even if he was in a rage or part of the plan to kill her.
No judgment from me on any action she took. She clearly did not agree to be butchered by this monster.
In the last thread, @Inthedetails wrote (and I totally agree with this):
"No matter where any of us fall on the spectrum of "judging/not judging SB/SD," I bet we all agree that even if it's wrong, the punishment should not be to be tied up, hit over the head, burned, and buried."
It is important to remember that as we look at this crime we can easily err on the side of blaming. ML erred in being to trusting of a man she was talking with but didn't deserve any of what happened to her.
Good point. I do think it's very possible they had met, but things didn't go the way they had before at some point along the way. Not necessarily right off. The dom/submission aspect makes sense as to why she would turn off her phone, willingly. And if he's dom, he gets to keep his phone on.
