Physical Evidence
Swabs taken from blood areas on the sweatshirt
Montgomery explained that each sweatshirt swab sampled blood from a specific area, not the entire garment. She confirmed that the swabs she tested contained no one's blood besides Dzhokhar Tsarnaev's, but did not know whether every droplet had been swabbed.
About
The redirect testimony limited the finding of only Dzhokhar Tsarnaev's blood to the tested swabs, rather than all blood on the sweatshirt.
