Thanks for the correction, I didn't realize our time-line had the corrected times. Let's hope they have the cell tower data, which I feel sure they would have with the FBI on this.
It is so strange for the Coxes not to have said a peep about this before, in all this time. It feels to me, by the way it's being disclosed to the media and not through official channels like the actual case file, as if there's a whiff of a grievance that comes with it, that the charges against Lori are thus unfounded (as if a week makes all the difference) - and from that I take that it's probably been discounted as credible evidence regarding JJ. Or, it is a recent discovery by the Coxes, and they decided to surprise everyone. That would really surprise me, if we get to find out that they didn't mention it to investigators before.
I think it has to be useful information to the investigation as a whole, IMO.
