I predict a mistrial or acquittal. Juan botched the case on cross for the most part.
1. He didn't establish a credible motive. No focus whatsoever on the May 26th text exchange (where he was very mean to her) and no attempt to link it to the May 28th "burglary". He seems to think that cancun crap is enough. It isn't.
2. No attempt to refute her claim that Travis guilted her into seeing him. Juan could have pointed out the flurry of phone calls she made to him on June 3rd to undermine her lies.
3. Never properly pointed out the inconsistency of her sexual talk and fantasies and her claims of being raped during the relationship. She claims she was anally raped in 2007. When describing this she pretended to act like she was raped, by pausing, crying, etc. Yet, just a little while later she's exploring her sexual fantasies with him, requesting facials and wanting to frak him like a "horny little school girl". Juan should have pointed out how far-fetched it was for a rape victim to continue to engage in mutual, enjoyable, kinky sexual relationship with her rapist. This would have crushed her whole "sexual abuse" crap. I don't feel that Juan made this point clearly enough.
4. He had her cornered on the rope issue. She bungled by admitting that she had no reason for throwing the rope away. Juan could have pointed out that "reason". The rope was imaginary -- conjured up to explain the knife's close proximity to the crime scene -- and her lie about throwing it in the dumpster was made up to explain why no rope was recovered.
5. The gun!!! He had her here too. All he had to ask was;
Juan: Isn't it true that the reason you disposed of the gun was because it didn't belong to Travis but to your grandparent and you knew that leaving it at the scene would have further implicated you?
There are other things, but these stick out the most.
