FILE - This combination of file photos shows brothers Tamerlan, left, and Dzhokhar Tsarnaev, suspects in the Boston Marathon bombings on April 15, 2013. Tamerlan Tsarnaev died after a gunfight with police several days later, and Dzhokhar Tsarnaev, was captured and is held in a federal prison on charges of using a weapon of mass destruction. The FBI has denied a claim made by lawyers for Boston Marathon bombing suspect Dzhokhar Tsarnaev that his brother and fellow suspect was asked by the FBI to be an informant. The Boston FBI office declined to comment on claims made in a court filing Friday, March 28, 2014. But the agency cited a statement it released in October in which it said the Tsarnaev brothers were never sources for the FBI, "nor did the FBI attempt to recruit them as sources."
