| Tracking Peterson by phone
August 24, 2004 Monday, a wireless telephone expert testified about Peterson's cell phone records in the days after his pregnant wife, Laci, vanished. Authorities used cell phone towers to track Peterson's calls and movements on Dec. 24, 2002, the day Peterson reported his wife missing. Mary Anderson, of West Palm Beach, Fla., works for AT&T Wireless as the director of national subpoena and court order compliance. Prosecutors are working to establish a timeline that they say places Peterson near his Modesto home within 10 minutes of when a neighbor said she found the Peterson's dog loose in the neighborhood, indicating Laci Peterson had already disappeared. Anderson said cell phone records indicate Peterson made a call to his voicemail at 10:08 a.m. on Dec. 24. That call bounced off a cell tower near the Modesto area, according to the records. She testified that no system is completely accurate and although AT&T detected the calls coming from certain towers, it is not a completely accurate way to track someone. On cross-examination by Geragos, Anderson conceded that even when someone is standing in one location, the cell towers can switch. Anderson acknowledged the records "are not 100 percent accurate," meaning Peterson may have been nowhere near his Modesto home when the call was made. Geragos pointed out that other calls placed by Peterson while he was standing in his front yard indicate the calls bounced off of several different towers. Anderson testified that cell phone calls to voicemail cannot always be accurately tracked to specific towers. "There appear to be some anomalies there," Anderson said.
