So, I have listened to this testimony a second time and have taken some notes. Some of this may have already been discussed.
At 2:32am there is a data usage call, this is not the same as receiving or sending text messages. This may be normal at&t activity at this hour.
For the 6:05am call, this is 23 second duration call, 1 second seizure time, and the calling party is seen as 8541511. This call, for some reason, does not show on the billable record. The TWC call records should have an indication of this call. These 1 second seizure times are interesting as it appears to be auto answered, such as calling 4762001. You hear no ringback tones when the call is auto answered as the call is answered immediately. So for a call received by a cell phone to have a seizure time of 1 second it would appear that the cell phone is set to call forward all to VM. Perhaps this is why the call is not billable as the billing part will only occur when the vm is retrieved?
At 6.25am, not on billable record, there is a GPRS call, internet browsing. This is interesting in that the HT records show him entering the store at 6:22am. So this must have occurred right after leaving HT on the first trip.
At 6:34am there is a call received from 8541511, 0 second duration and no seizure time indicated. So this call was neither answered nor forwarded to vm. I wonder if seizure time is recorded for calls that are not answered, the reason I ask this is that the seizure time would indicate the amount of time it took to possibly locate the phone.
At 6:37am, an outbound call to 4672001, 29 second duration with a seizure time of 1 second. This indicates that seizure time must be recorded for outbound calls from cell phone. This call was tracked to cell tower X.
At 6:40am, an inbound call from 8541511, 32 seconds in duration and a seizure time of 8 seconds. This call was tracked to cell tower Y. I am not implying anything odd with the different cell towers. I would only find it interesting to know where cell tower X is located as it relates to where NC's body was found. This is the call from NC according to BC.
At 6:45am a call to cell phone VM, duration of 63 seconds.
At 6:46am receives a text message.
At 6:47am another call to cell phone VM, duration of 25 seconds.
Great summary. Thanks.
