I just finished watching the entire trial, and I'm currently reading Juan Martinez' book. I'm left with a few questions:
What is your theory on what happened with the license plates? When did JA take them off the car, and when did she put the back plate back on? Outside Travis' house after the murder?? Did she not notice it was upside down?
How on earth could the car rental place write off the stains in the car as red kool aid, and wash it out?
Why do you think JA killed Travis three times? Do you think she slashed his throat to get him to stop screaming, or to make sure he was dead? Why the final shot in the head?
How come no one heard the gunshot?
Why do you think JA left the camera in the house?
I have more q's, but that's all I can think of right now.
About why kill him 3x.....
Steve's answer - that she did so because she's psycho- is both apt and beautifully succinct.
My opinion (never succinct, but hopefully apt at least here & there):
Having a gun was clearly extremely important to her, since she went to the effort, however clumsy, stupid, & self-defeating, of staging a burglary to obtain one.
To have is not necessarily to use, though,and IMO (on most days) is that she didn't intend to actually shoot him with it. The plotted and planned his murder for a long time. She didn't just want to kill him, she wanted to torment him as much as she could , in every way she could, before she stabbed him in the shower. Her texts and journals make plain that she remembered every "slight" by Travis, and that she forgave him not at all for anything, ever.
I think she brought the gun to mock him with it in the shower (his near death experience when a gun was pointed at his head), which would also have had the benefit of having him focus so much on the gun that he'd be utterly off guard when she pulled out the knife and stabbed him.
I think she slashed his throat out of increased rage that he hadn't conveniently died in the shower, as she had imagined he would, that he had resisted her will all the way down the hall, that he had kept on trying to talk.
And, am least sure why she shot him after she slashed his throat, except to speculate perhaps she just hadn't gotten her fill of killing him yet.
About why leave the camera? For me, that's one of the biggest don't knows, and from JM 's post- book interviews, I think he really doesn't know either.
