BSL's confession of events leave out that fact IMO that he almost definitely sexually assaulted both Lisa and Mickey.
First, I have my own doubts as to Lisa going to "stay" with him on her volition - if he didn't force her to go with him, I feel like when she went willingly she didn't think she was going to be staying with him for days....I think he held her against her will for several days (and if he went to work, etc, what did he do with her during those days to prevent her escape?) even though she pleaded with him that she missed her kids. At one point while he was asleep, she was able to try to get his keys/wallet when she left (not just for $ but maybe to have his ID to show police?), he woke up, saw it and killed her. IMO, it's highly likely he was keeping Lisa to sexually abuse & control her; I don't think she had any idea what she was getting into or ever "stayed" with him willingly.
I hate to say it or think about it, but I also doubt he didn't rape Mickey. I think it's highly likely he raped her during/before/right after stabbing her the four times in his truck (based on what I've read about sexual preadtor serial killers).
When Mickey "jumped up" (I agree with some WSers that is a hinky way of wording it) and attacked him, he may have been raping her or attempting to rape her again (even if he thought she was dead - some serial killers such as Ted Bundy have admitted to repeatedly having sex with the corpses). He didn't have the knife in his hands because he thought she was dead. Maybe it was in the center console or on the floor of thr truck. She managed to grab it somehow and start stabbing (maybe this would explain any cuts/slices on/near his back) if she slipped her hand down below & grabbed the knife out of his eyesight while he was on top of her and then she stabbed him in the back/side/etc - that would be kind of a sneal attack and might seem to work better than brandishing the knife in his face. I hope this makes sense.
I am sorry to write these awful things but I do not for one second believe a tier three RSO didn't rape both of these women. He just hates being labeled a sex offender, so he won't admit it.
