What female DNA on the Boston bombs does, and doesn't, mean

Federal investigators have gathered a DNA sample from Tamerlan Tsarnaev's widow, but they may be grasping at straws

On Monday, federal investigators disclosed that a bit of female DNA was found on a fragment of at least one of the pressure-cooker bombs that killed three people and wounded more than 200 others at the Boston Marathon. Also on Monday, the FBI visited suspected bomber Tamerlan Tsarnaev's widow, Katherine Russell, to collect a DNA sample to see if it matches the material found on the bomb.

Russell, 24, has been staying at her parents' home in Rhode Island since her husband's death, and the focus on her "is part of the wider effort by the FBI to determine who else may have played a role aiding the bombers," say Michael S. Schmidt and Serge F. Kovaleski in The New York Times.
