Authorities are widening their gaze in the Boston Marathon bombing case to the Tsarnaev brothers' closest associates, including Tamerlan’s mysterious widow, Katherine Russell. New details on Russell, 24, paint the picture of a privileged East Coast girl, who played alto saxophone, sketched pictures of cats, and bought clothes (and once stole) from Old Navy. Russell’s friends from college—who a classmate describes as “straight out of Sex and the City”—say she was “infatuated” with Tamerlan upon meeting him. By 2010 she had dropped out of college, converted to Islam, and married him. The FBI’s investigation into her role in the bombings is ongoing.
