I do here what you're saying, and yes, I'd really like to think if there was evidence of phone calls
or what not, they would have brought it in, but then again I also would have thought they would have had a MUCH stronger case before going to trial, so who knows? They did mention something early on about proof of contact between the two, but alas, nothing. Someone at work mentioned that perhaps it was a call to or from a landline in their house, and the DA didn't bring it up because it could point to Christina as well, but again, that's purely speculation.
I'll be interested to see what comes out in the wrongful death suit...
