The FBI informed the FSB that it "did not find any terrorism activity, domestic or foreign" in its investigation into Tamerlan Tsarnaev. A subsequent FBI request for more cooperation and clarifying information from the FSB went unanswered. Each of Tsarnaev's parents told Russian television networks that the suspected bomber believed he was under continued FBI surveillance.
Three men, including one who was a close friend of Tamerlan Tsarnaev, were fatally stabbed in the neck in an apartment in Waltham, Massachusetts. Authorities are investigating whether Tsarnaev had any connection to the unsolved triple homicide. At the time of the stabbings, the local district attorney's office said it appeared that the victims knew their assailants and that the attacks were not random.
Dzhokhar Tsarnaev transferred to the University of Massachusetts-Dartmouth from the University of Massachusetts Boston. His classmates remembered him as a friendly, pot-smoking student who took easy classes and got middling grades. He brushed off invitations to join the Muslim Student Association on campus.
Tamerlan Tsarnaev departed the United States for Russia for a six-month visit. For at least a month in the summer, Tsarnaev helped his father renovate his first-floor apartment next door to a dental office in Makhachkala, a city in the Dagestan region on the Caspian Sea. It was unclear what else he did while he was in Russia, whether he traveled elsewhere and whether he met with any members of radical groups. "They say he was a fanatic. I didn't see that," a neighbor of Tsarnaev's father told Reuters.
Dzhokhar Tsarnaev was sworn in as a naturalized U.S. citizen. Tamerlan Tsarnaev applies for U.S. citizenship. Because of the previous FBI inquiry into his activities and the prior domestic abuse complaint against him, Tsarnaev's application prompted "additional investigation." He was still under consideration for citizenship at the time of the April 15 bombing.
Tamerlan Tsarnaev interrupted a sermon at the mosque of the Islamic Society of Boston to object to a preacher's call for Muslims to celebrate holidays like July 4th and Thanksgiving just like the birthday of the Prophet Muhammad.
