(NEWSER) – At least one of the bombs used in the Boston Marathon attacks had female DNA on it, investigators say, but that doesn't necessarily mean the bombers had a female accomplice. Officials gave a handful of alternate scenarios to the Wall Street Journal: A store clerk could have handled materials later used in the bomb, or a female hair could have innocently ended up on it. The Journalnotes that FBI agents were seen leaving the home of Tamerlan Tsarnaev's in-laws today. Tsarnaev's widow,Katherine Russell, has been staying there since the bombings, and one official says the agents were there to get a DNA sample from her to see if it matches the one found on the bomb.
