I place no blame on the state or the judge for not crossing her in the beginning. There was nothing to cross her for. You don't cross someone off for cause for having DV in their past if they say they can remain impartial about it. It's their word and you have to accept it. I don't think Juan was super concerned about DV victims, especially if there were more strike worthy candidates. He may have thought, like many of the posters here, that a true victim of DV might see through the lies. There was a male juror who had experience with DV in his past let on too. It's a crap shoot. And, again, doing in depth research into their backgrounds doesn't seem typical to me.
As far as Juan not doing more research on her ex husband, I don't think that is typical of research that the state does when vetting jurors and seriously, how would it ever cross his mind to look for that, especially when the juror does not appear to have disclosed his earlier first degree prosecution? The prosecution she did disclose to him would not have been prosecuted by him either, as he has been a homicide prosecutor for quite some time now. Was he even allowed to ask her for his name so he could research him? Sure a bunch of "grandma types" found the info, but, again, this isn't something the state will ususlly look for. There's an expectation of honesty when questioning jurors. I remember AZL saying during jury selection that the lawyers will look for things that will show them a juror was honest. This juror was forthcoming about her husbands' legal issues and that probably tipped to him that she was being transparent and didn't appear to be TRYING to get on the jury. He otherwise seems to have done a stellar job selecting the jury so it makes you wonder.
He did try and get her removed a couple times which is interesting. I'd like to know more about that. If the defense had asked for it she'd be gone in a New York minute.
Like I said before, I won't blame the state for someone else's deceit. Yes, deceit. She lied by ommission by not mentioning Juan was her ex husband's prosecutor. There's no way she didn't know this and no way she didn't know this was important information and no way she told them this and Juan let her stay on. If she comes out and offers some logical explanation for why she didn't reveal this info I will eat my words. But I'm not gonna pretend to be blind to what is in front of me.
