What it does show is more of Barry's lies.
He said the marriage was great, they were not on the rocks (my wording), he never cheated and you won't find any evidence of it.
Detective: So you never searched "cute girls in Salida"
Barry: No, I wouldn't do that.
Lies! Why would he lie about that knowing they have his phone record? He thought he deleted that stuff.. had no idea they could find it and they did and it was another lie he told.
A husband desperate to find his wife, would say, yes I searched for that, we were having a hard time earlier this year.... something anything to clear himself so they would move on and find the person responsible. But, he didn't, and he knew he is the person responsible so the only thing he can do is lie and say it wasn't him that searched that or this other best response, "I don't recall"...
