... the phone was very active after appearing to off on Saturday and Sunday.
Still trying to understand, hope you can help. I believe you indicated that Cingular did not begin pinging the phone til the evening of Monday, April 3, 2006, right? So prior to that, from 2am on Saturday April 1 to Monday evening, the phone was not used, and was either turned off or only seemed to be turned off such as if it was blocked from connecting to a tower, such as if it were buried or in a lead-lined pouch etc. Right? And then from Monday evening onward, the phone still was never again used, but for 30 days Cingular was pinging to the phone, and pings from a number of Columbus area towers reached the phone over that 30 day period. Right?
Potential conclusions?:
1)
Brian's phone was never used to make a call from the time he was last seen (had it been, Cingular would have had a record of that).
2) Some of the special pings transmitted from Cingular towers (nationwide?) over the 30 days reached his phone, and all of the towers from which successful pings were transmitted were in the Columbus area, meaning
his phone was in the Columbus area at that time, and presumably within 20 miles or so of the various towers pinged.
3)
The phone retained a charge through at least April of 2006.
You stated that 'the phone was very
active after appearing to be off on Saturday and Sunday.' This I find confusing. Why do you conclude that the phone was active beginning Monday? Don't you mean simply that that is when Cingular commenced sending pings and the phone began receiving pings from various Cingular tower in the Columbus area? But that doesn't mean the phone was 'active', does it? Doesn't it just mean that a) the phone battery had sufficient charge left to receive the pings from Cingular and b) the phone was within 20 miles of each and every tower from which pings were successfully transmitted to the phone? So by active, you don't mean the phone was in use, you just mean that it held a charge, was in the Columbus area, and received pings from multiple Columbus area towers, right?
Finally, a separate question is
is there any evidence the phone was moving. Cingular sent pings across its network of towers, and some towers in the Columbus metro area reached the phone. Some have inferred that, since successful pings were transmitted from multiple towers rather than from a single tower, this suggests or means the phone was moving. Is it legitimate to conclude from the ping data that the phone was moving (it would seem to me as a layman that the conclusion to draw would be simply that the phone was somewhere in the midst of the various towers from which pings were transmitted that successfully reached the phone)? I have my doubts (I think it likely Brian died April 1, and find it unlikely that someone was moving around the Columbus area with his phone), but I don't understand the tech enough to know.
