I'm curious why his phone wouldn't ping at the same time as hers did at 4:47 a.m. I can see hers not pinging at 4:56 if the battery finally went dead, but how does his ping at 4:56 but not at 4:47?
One of the items I've wondered about, too. I'd really like to know when CM's communications stopped.
And I realize her phone may have run out of juice, but if she got in EA's car to ride somewhere, wouldn't she have charged it in his car? Either way--when she quit using her phone, or it died, the time frame is important.
