AT&T phone-activity records for the number ending in 5112
The AT&T records included a 6:50 p.m. outbound text and a 9:03 p.m. data-usage entry on January 31, 2013. Grant acknowledged that the text went to Tamerlan and conditionally agreed to focus on it if the data-usage entry was unreliable.
About
The records were used in a plot placing the defendant's phone in Dartmouth during a pressure-cooker purchase in Saugus; cross-examination challenged the data-usage entry's location reliability.
