Testimony continues in the trial of the admitted Boston Marathon bomber, Dzhokhar Tsarnaev. This week, it has focused on the bombs that exploded at the finish line of the Boston Marathon in 2013 — as well as those that exploded days later, in an altercation between the Tsarnaev brothers and Watertown police.

Edward Knapp, a supervisory special agent with the FBI, has spent much of the day testifying about how the bombs were made and the destruction they left in their wake.
