This is a ridiculous lie though. there were certainly less incriminating ways.
And you totally leap frogged over the most important detail IMO. She was in a bathroom with the door locked and a PHONE and she didn't call anyone? Forget about fearing he'd kill her, if he was that violently out of control why not call a friend?
It's too big of a gap for me.
His side has some major issues as well, but one thing I DO understand is that he was relying on his hearing in the blackened room. I am hearing impaired and hearing sounds is something that can really be confusing if you think the sound is coming from one place.
If he placed her via sound as on the bed, then he'd totally convinced his mind that she was on the bed. He may have even heard breathing or noises coming from her that were totally imagined.
Here's another detail btw that I considered. If she had gotten up to use the bathroom and fell asleep on the toilet, maybe leaned over with her face on her knees, and he shot her, the compact nature of her position and the 'relaxed" state of the body prior to shooting her would make her moving around less likely.
If she was sitting on the toilet (granted we only have his word) when he found her, than IMO this is kinda weird. Because if she was tensed up and terrified and then was shot in the head, chest and arm, her body would have jerked and collapsed.
