Bomb DNA Not From Tamerlan’s Widow

The female DNA and fingerprints found on fragments of a bomb found at the Boston bombing scene do not match those of Katherine Russell, the widow of dead suspect Tamerlan Tsarnaev, but the FBI is still not entirely convinced that she’s not connected to—or at least had knowledge of—the attack. “I think they’re very skeptical of her story,” said former assistant FBI director and CBS News correspondent John Miller. “They want to know, is it possible all of this was going on concealed from you, or did you know the whole time?” Of particular interest is a phone call between Russell and Tsarnaev made hours after his image was first released by the FBI as a suspect.
