Crime Scene
Scene B
Witnesses identified Scene B as the second explosion site near the Forum restaurant on Boylston Street. Sarah De Lair described recovery of human remains, bomb components and backpack parts, while Jason Costello mapped evidence locations. Edward S. Knapp testified about radio-control components associated with the site, and Elena Graff explained that fingerprints on recovered paper and cardboard established contact but not its timing.
About
Scene B supplied physical evidence about the bombing that prosecutors attributed to Dzhokhar Tsarnaev and underlay a bombing-a-place-of-public-use count. Prosecutors also argued that audio recorded nearby would help jurors weigh an aggravating factor.
