Female DNA has been found on at least one of the bombs used in the Boston Marathon attacks, according to a new report.
But it isn’t clear if that means a woman helped suspects Tamerlan and Dzhokhar Tsarnaev carry out the attacks.
U.S. officials told The Wall Street Journal there could be several explanations for the DNA, including that it could have come from a store clerk who handled the materials the two brothers allegedly used in the bombings. A stray hair that landed on one of the explosives could also explain the DNA finding.
Authorities are trying to determine whether the brothers had any help in the attack which killed three and injured more than 260 when two bombs exploded near the finish line of the Boston Marathon on April 15.
FBI agents have visited the Rhode Island home of Tamerlan Tsarnaev’s in-laws and carried away several bags.
FBI spokesman Jason Pack confirmed agents went to the North Kingstown home of Katherine Russell’s parents on Monday. Russell, Tsarnaev’s widow, has been staying there.
Russell did not speak to reporters as she left her attorneys’ office in Providence later in the day. Attorney Amato DeLuca says she’s doing everything she can to assist with the investigation.
Attorneys have previously said Russell and her family were in shock when they learned of the allegations against her husband and brother-in-law, Dzhokhar Tsarnaev.
