U.S. intelligence knew more about the movements of one of the Boston Marathon bombing suspects than previously reported, U.S. officials said on Wednesday, raising more questions about the government’s handling of the case and the sharing of information among agencies.
U.S. officials, speaking on the condition of anonymity, said the FBI was alerted when Tamerlan Tsarnaev traveled to Russia last year. They also said Russia, which had tipped off the FBI about its concerns over Tsarnaev in early 2011, made a second, identical request to the CIA in late September 2011.
Police say the ethnic Chechens Tamerlan and Dzhokhar Tsarnaev planted and detonated two pressure-cooker bombs near the finish line of the marathon on April 15, killing three people and injuring 264.
