The MPD suspected Scott wasn't telling the truth about his activities that morning and wanted to verify each detail. The timing of the 10:08 call to check voice mail is used to pinpoint Scott's location and to indicate that he was just leaving home, contrary to the 9:30 time he told officers (Brocchini, pg. 4). Coupled with the 10:18 time Karen Servas says she found McKenzie, the Prosecution claimed an abduction of Laci by someone else other than Scott had to occur within these 10 minutes.
People's 203 contains the phone records (phone bill for Dec 28, 2002), fraud records (showing the cell tower which handled each call), and charts used to establish the facts for the Prosecution.
The fraud records were entered as exhibits to establish the fact that Scott's call was first picked up by the Brighton cell tower, which services 523 Covena, and then transferred to the 10th & D tower, which services the Warehouse on Emerald. Jacobson prepared a chart to show his analysis, People's 203D.
To verify the accuracy of the fraud records, Jacobson obtained an AT&T cell phone on the same network as Scott used (Jacobson).
On his first test, he started exactly at 10:08 am at 523 Covena and placed a call. He headed north to where Covena dead-ends, made a westbound turn on to Edgebrook, followed Edgebrook all the way down to La Loma, until the other person indicated the 1 minute 21 seconds was up. The call started out at the Brighton cell tower and when it ended a minute 21 seconds later, the last originating cell tower location was 10th and D Street. (Jacobson)
In the second test, Jacobson went south on Covena to Encina, headed westbound on Encina. About a minute and 21 seconds later, he was at the intersection of La Loma. In this test, too, his originating cell site location was 1250 Brighton Avenue and termination cell site location was 10th and D Street. (Jacobson)
In the third test, Jacobson went south on Covena and stayed on Covena. The 1 minute 21 seconds ended at the intersection of Covena and Miller. The call originated at the Brighton cell tower and terminated at the 10th and D Street tower. (Jacobson)
In the fourth test, Jacobson departed from the warehouse on Emerald and drove south for 1 minute and 21 seconds. The originating and terminating cell tower was 929 Woodland Ave. He repeated this test exactly and had the same results. (Jacobson)
The Prosecution used these test results to prove that Scott began his call to check voicemail as he was leaving his house at 523 Covena and headed towards the Warehouse.
In addition to these three tests, Distaso asked Jacobson to verify the number of voice mail retrievals Scott made when he was known to be at 523 Covena that were picked up by the Brighton tower (Jacobson).
