Dzhokhar Tsarnaev graduated from Cambridge Rindge & Latin School. He was an all-star member of the wrestling team and won a $2,500 scholarship from the City of Cambridge. Friends and acquaintances remembered him as cheerful and wanting to fit in, "all-American kid in every measurable sense of the word."
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.
