Not from cell ping info, still, seems appropriate to post here. I'm carrying this over from the EPass thread:
George states he's working Sun-Thu schedule. He also states at the end of the month he's working some extra...going in early. He doesn't state the circumstances of his seeing Casey leaving the house (e.g. where he was at the time), but, it almost seems that he may be driving up to the house since he sees her leaving the house (like he wasn't there at the time) and decides to give chase.
EPass records for 6/29 8:48AM, 8:53AM & 9:09AM agree with the route he described taking in the "chase" scene, and IMHO, the brief time period between toll booths suggests he was moving at a decent rate of speed. Someone could calc the ave speed using google to locate the booths, get distance and diff. in timestamps if interested.
There are no cell records from Casey <10:25AM 6/29 until she texts Amy asking about her gas can (recall the Pontiac is @ Amscot allegedly out of gas).
Speculation: Casey attempted to use Tony's dark colored Jeep Grand Cherokee to retrieve gas cans from the Anthony's home 6/29 <10:25AM and was surprised by George driving up. She spotted him driving up at a distance and pulled away in time for George not to get close enough to notice it was a Jeep GC vs. Cindy's Toyota 4Runner. IF George saw Casey he may not have payed close attention to the vehicle (your mind will convince you something is true if you believe it to be) and it would make sense to him she'd be in the 4Runner vs. another vehicle altogether.
This would explain:
(a) why Casey would be @ the house in something other than the Pontiac,
(b) why George thought she was in Cindy's 4Runner,
(c) why there are no EPass records for Cindy's 4Runner matching George's HHR
(d) why the first cell activity of the day is a Plan "B" to Amy about gas cans
(e) why Cindy would state that it never happened since she likely knew her 4Runner never went missing.
(f) why George's epass account establishes him traveling ~86mph between tolls
IMHO, we can, with high-confidence, conclude that the morning of 6/29, was, indeed, the morning of the "chase".
