So what you are saying is that you know he had another shower earlier, and that she left Yreka with a written plan to kill him in the shower?
While I don't know for sure he had a shower earlier, I think he likely did. There is no soap, no shampoo, no washcloth in those photos. His arms are high above his head in a number of the photos, spaced throughout the eight minutes. It's almost literally, "stick 'em up." But I believe, and suspect the prosecution also believes, that she planned to murder him in the shower. There is precedent for it in the Psycho Shower Scene. She was a fan of old movies and was surely aware of that classic.
His shower was a tiny one. For some reason the shower pics make it appear bigger than it was.
She had to corner him, and what better place than to not only trap him in the shower, but make him sit down in the shower to make him small and less able to defend himself. If the shower weren't important to her in the context of the murder, she wouldn't have bothered to drag him from the end of the master bedroom, where he'd reached, back along the hallway to the shower. I believe that was her plan all along, to leave him dead in the shower.
Think about it. If you want someone dead and intend to get away with it, you need a plan, a very well thought out plan. Jodi had that. To quote a reporter who live-blogged Prosecutor Martinez' opening statement, "Martinez says Arias attacked Alexander in the shower, because his defenses were down."
I am not the least bit psychic. But when I see the shower photos, not just the final few but all of them, I'm filled with a sense of dread. It jumps out at me that he was being controlled by a gun. Many others have had a similar reaction. I could be wrong but it's my visceral reaction.
I'm interested in hearing whatever thoughts and theories you might have. You could be right and I could be wrong.
