Fitzgerald's phone-location slides, maps, and diagrams

The slides showed calls at approximately 2:49 p.m. and 2:51 p.m. on April 15, with data consistent with Jahar near the Forum restaurant and Tamerlan near Marathon Sports, rather than pinpointed locations. Fitzgerald explained that the timestamps reflected network activity rather than necessarily the start of conversation. He said most displayed calls on later dates were not between the brothers and illustrated only each phone's general area.
