No court dates have been set yet . Blanch added that his client has no involvement in the Boston bombing incidents . `` I think she found out about her brothers the way the rest of the country did -- on the news . '' Suspect : Boston bombing was payback for hits on Muslims . Tsarnaev 's younger brother Dzhokhar Tsarnaev , 19 , is currently being held in federal prison and has been charged with using a weapon of mass destruction . Her older brother Tamerlan Tsarnaev , 26 , was killed in a shootout with Boston police days after the bombings . One victim of the April 15 attack remains hospitalized .
