no, no problem. I appreciate the discussion. IMO 'who did it?' can be analyzed by looking at the how, why, what of it, and it's essential to analyze the pre-crime prep as well as steps inside. The problem I have with most theories is that I can't get from beginning to end with them. So I want to step-by-step this. anyway. My first post on ws described how I went through the scene in my head. Part of the post and if you look at a schematic, you'll see how he could have been trapped, esp if e woke up and had a weapon. Even if he hadn't been caught, there'd be potential living witnesses to id him.
I think he’d have gone in through the second floor sliding door after he was sure everyone was asleep, not through the first door with the keypad, even though he might know their code. I believe the first floor only has one possible exit. He would not let himself be trapped. On the second floor, he would have three potential door exits. Even on the 3rd floor, more options and he’s in good shape, so he could jump from the third story window or deck, if needed.
He’d go to the second floor bedroom first. E, the biggest and potentially undesirable victim. He'd cut arteries & vocal chords. Even if E woke up and fought, it would not be for long. Same with X to silence her, but she fought back. He might even have pre-cut duct tape for over the mouths. The police are saying no one was bound and gagged, but did anyone ask about adhesive residue? Or tape left over the mouths?
