Of course she could have left a bloody handprint without being the perp, it doesn't necessarily clash with a scenario in which they were both attacked or if there was a fight between them, etc.
What I always wondered was, if she'd really attacked him with a knife by herself, wouldn't he have just taken the knife away from her? Wouldn't he whirl around and take the knife? He was a lot bigger than her. Why would he sustain so many wounds to his back and not turn around to stop her, unless he was busy fending off other injuries from the other side at the time? So I kind of never completely gave up on the theory of more than one perp, I mean the injuries could fit that scenario. If it were only her, how could she do that much damage and not sustain much more damage herself?
Also of course, if she was the perp why leave the camera, it's like it was either placed there to be found or else placed there by a very confused and disoriented person, definitely not someone trying to cover her tracks. And if she'd gone there with any plan to commit murder, why allow herself to be photographed, why hang around doing any of the things she did or submit to any of the things she did? Why spend so much time she would later have to account for? I always kind of wondered about the possibility that she was drugged, or if both of them were. The crime scene was so disorganized. So much of this case hinged on her confession really, but how reliable was that? I don't know. Edited to add, of course all this is purely theoretical as the jury already reached a verdict.
I see that if someone plunges a knife in your chest, knicks your vena cava and your lung, you are probably very concerned with breathing at that point. We have evidence that Travis grabbed the blade of the knife. That causes nothing but more pain and less ability to fight.
It also lends to TA's personality, his state of mind, and the nature of the attack, if you ask me. The fact that JA wasn't hurt besides her hand can be indicative of TA: 1, not wanting to hurt anyone and not being violent, 2, TA only wanted to get away and there was no anger or rage to provoke her, 3, the attack was unexpected.
Of course, number 1 sounds hard to fathom if you are being attacked, but I saw a story once where a rape victim said she had a gun to the attacker's chest and was unable to pull the trigger. She just couldn't take a life. Well, he raped her. Lucky for her, he didn't kill her, and she was the only victim he'd left alive.
As for the camera, I would tend to believe she forgot it. I think she deleted all the pictures, tossed it on the towels maybe, and carried it on accident to the washer. There is no evidence of bleach in the first load that was in the dryer, so I tend to believe Travis had put the first load in. It's just too much time for her to be in the house while the first load washed and then for her to put in a second load. I think Travis started cleaning the house after to sex as a hint for her to leave.
She allowed herself to be photographed because she knew she was going to get rid of the pictures, possibly take the camera if she'd remembered it, and this is speculation on my part, but she might have tried to go back and get it, but couldn't because the roommate was already home. You also have to ask--whoever the perp was--why would ANY perp leave the camera?
As far as the time she spent, my theory is that she'd planned to arrive at 3 or 4am, kill Travis and keep going to Utah. If she could have killed him at 3 or 4am, she would have been only 3 or 4 hours late to get to Burns. But when she arrived, the new roommate was home. She didn't expect that. And she was probably exhausted from all the driving, so she slept, which was why she didn't kill TA the moment Enrique went to work.
Her plan might have been to shoot Travis in his sleep, but it was a very different thing to deal with an awake Travis. I believe she definitely arrived at 4am because of the way she described the daft punk hands video he was watching when she arrived. In her interrogation video, I hate to type this, but she seemed genuine when she described this "stupid" video with people with boxes and foil on their heads. Her tone really did sound as if she hadn't seen it before. She also described the floor cleaning situation in the same manner, which led me to believe she'd probably had a shower after sex and went downstairs to find him immersed in cleaning the floor. To keep his attention on her, she probably lured him into the office to see the CD's she'd brought for him and to have sex again.
So now, Travis really needs a shower after two sex sessions. And she comes up with this shower photo session scenario. OR he tells her he's about to shower and thanks for stopping by, she pretends to leave, but the next thing he knows, she's in the bathroom, snapping pictures.
One thing I can say for sure, a murder planned in her mind isn't the same as executing it. So that's why it's all disoriented. You can study the progression of serial killers to easily understand that the first crimes of a serial killer are a lot less organized then say their 10th or 11th.
