Article Photos: Officials: Suspect described plot before Miranda 1/13

FILE - This combination of undated file photos shows Tamerlan Tsarnaev, 26, left, and Dzhokhar Tsarnaev, 19. The FBI says the two brothers are the suspects in the Boston Marathon bombing, and are also responsible for killing an MIT police officer, critically injuring a transit officer in a firefight and throwing explosive devices at police during a getaway attempt in a long night of violence that left Tamerlan dead and Dzhokhar captured, late Friday, April 19, 2013. Tamerlan and Dzhokhar Tsarnaev sought to embrace American lives after immigrating from Russia _ joining a boxing club, winning a scholarship and even seeking U.S. citizenship. But their uncle last week angrily called them “losers” who failed to feel settled even after a decade of living in the United States. (AP Photo/The Lowell Sun & Robin Young, File)
