In its penalty-phase opening, the defense said the Tsarnaev family arrived in Cambridge, Massachusetts, in 2002 and described family circumstances as part of its explanation of Tamerlan's influence over Jahar. Philip Christiana testified that he assisted an operation there on the night of April 18, 2013. Sonya Petri identified Cambridge as the site of Magomed Dolakov's April 30, 2013, FBI interview while introducing the interview report.
