Tamerlan Tsarnaev
Female DNA has been found on one of the bombs used during the Boston Marathon bombings. A fingerprint and DNA were recently lifted off of a bomb fragment. It is so far unknown if the fingerprint was there before the bomb exploded or if the fragment was touched after the explosion. The FBI is currently questioning all females that could have been in contact with the Tsarnaev brothers, including the widow of Tamerlan, Katherine Russell. The female DNA was found on the pressure cooker that held the bomb. Read more below.

The FBI has already launched an investigation into Katherine Russell, taking her computer and more from her home as evidence. The investigation is hoping to discover if Russell “wittingly or unwittingly — destroyed evidence, helped the bombers evade capture or even played a role in planning the attacks.” She has also been asked about the relationship and conversations her husband had with his mother, but she does not speak Russian so can be of no assistance. Thus far, Russell has been working with the FBI as well as she can.
