Earlier today we heard unsubstantiated chatter that FBI agents were in front of the house of Katherine Russell in North Kingstown, widow of the dead bombing suspect Tamerlan Tsarnaev. Moments ago we got an explanation for this. The WSJ reports that "investigators have found female DNA on at least one of the bombs used in the Boston Marathon attacks, though they haven't determined whose DNA it is or whether that means a woman helped the two suspects carry out the attacks, according to U.S. officials briefed on the probe. The officials familiar with the case cautioned that there could be multiple explanations for why the DNA of someone other than the two bombing suspects—Tamerlan Tsarnaev and his younger brother, Dzhokhar—could have been found on remnants of the exploded devices. The genetic material could have come, for example, from a store clerk who handled materials used in the bombs or a stray hair that ended up in the bomb."
More from the WSJ:
On Monday, Federal Bureau of Investigation agents were seen leaving the Rhode Island home of the parents of Katherine Russell, the widow of Tamerlan Tsarnaev. The elder brother died after a shootout with police four days after the April 15 bombings.
Ms. Russell has been staying with her parents since the bombings, and FBI agents have been seen posted outside the home since her late husband was identified as one of the bombers. Her lawyer has said she is "doing everything she can to assist with the investigation."
One official familiar with the case said agents went to the house Monday to collect a DNA sample from Ms. Russell, the culmination of days of negotiations. FBI officials also have been negotiating with Ms. Russell's attorney in recent days to get fuller access to question her, the officials familiar with the case said. The officials briefed on the investigation said the DNA request was needed to determine whether it matched the DNA found on the bomb remnants.
Ms. Russell is one of as many as a half-dozen people in whom investigators are interested as they seek to determine if the brothers had any help in the bomb attack or the days afterward, the officials said. Ms. Russell's lawyer didn't immediately respond to a request for comment about the latest developments.
Well if there was one specific group in society that had so far evaded persecution over recent events surrounding the Boston bombing, and other recent social risk flarings, it was women.
It looks like it is time to close the loop on that.
