In an investigation that seems to go in a new direction every other day, some incriminating evidence is causing officials to take a deeper look into Katherine Russell, the 24-year-old of Tamerlan Tsarnaev.
The Washington Post reports investigators are trying to determine how issues of Inspire, the Al Qaeda magazine that taught the Tsarnaev brothers how to make the bombs used to carry out their attack, and other "radical Islamist material" found on their way onto her computer. They're trying to figure out whether Tamerlan downloaded the material without her knowing or if the suspect's widow knowingly had the magazine on her computer. Dzhokhar has reportedly told police the brothers made their pressure cooker bombs at the house where Tamerlan lived with Russell and their young child. The New York Times reports investigators are also looking at a text message Russell sent Tamerlan after pictures of the brothers, 26-year-old Tamerlan and the19-year-old surviving suspect Dzhokhar Tsarnaev, were released by the FBI. Russell did not contact police.
So far, those are the two biggest pieces of evidence hinting Russell might know more than she's letting on. She has said she had no idea what the brothers were planning and that she was "utterly shocked" when the brothers were identified as the suspects. DNA tests revealed the female DNA found on the Boston marathon bombs did not belong to Russell. Around the time the female DNA evidence was found and the fourth of July attack plans were revealed, Russell stopped cooperating with police. Officials are also trying to determine how much three of Dzhokhar Tsarnaev's college friends knew about the brothers' plans.
On Friday, a Massachusetts funeral home announced Tamerlan Tsarnaev died of gunshot wounds and blunt trauma during the Thursday standoff with police. The funeral home is now struggling to find a cemetery that will accept the accused bomber's body. No one wants him.
