As the manhunt for Boston Marathon bombing suspect Dzhokhar Tsarnaev, learn more about him and his brother, Tamerlan, who died after a shootout with police early Friday morning.
Police in Watertown, Mass., are hunting for a man they identified as 19-year-old Dzhokhar Tsarnaev of Cambridge, Mass.
Sources told CNN Dzhokhar Tsarnaev and his family came to the U.S. on a tourist visa in the early 2000s. They asked for asylum, and Dzhokhar Tsarnaev became a citizen on Sept. 11, 2012.
A headmaster in at a school the younger man attended in Dagestan, which is a region near Chechnya, said the family, which included two brothers and two sisters, arrived in that area in 2001. An uncle said the family arrived in the U.S. in 2003.
Dzhokar Tsarnaev attendedCambridge Rindge and Latin, a public high school in Cambridge, Mass.
Dzhokhar Tsarnaev used to work as a lifeguard at a Harvard University pool. George McMasters, the manager who hired him two and a half years ago, told CNN he was impressed by Tsarnaev's work ethic and seemed like a "very quiet, unassuming young man." McMasters was deployed to Afghanistan last year and Tsarnaev was no longer working at the pool when McMasters returned to the U.S.
Tamerlan Tsarnaev, 26, came to the U.S. a few years after the rest of his family, sources told CNN. He was legally in the U.S. on a green card.
Tamerlan Tsarnaev studied engineering at Bunker Hill Community College, according to CNN.
The older brother had taken a year off from school to train as a boxer, according to CNN.
According to CNN, a posting under Tamerlan Tsarnaev's name on a social media website included the comment, "I don't have a single American friend. I don't understand them."
Tamerlan Tsarnaev died after a gun battle with police early Sunday morning, police said.
A source told CNN Tamerlan Tsarnaev was wearing explosives and had a trigger.
The suspects are originally from Chechnya, a Russian republic in the Northern Caucuses region. However, a source told CNN not to assume they were radicalized because they originally came from Chechnya.
Alvi Kamirov, the spokesman for Chechnya's president, said the brothers had not lived in the country for many years and had not lived there at all as adults. He said the attacks are not Chechnya's fault, because the suspects had been brought up in America, according to an Interfax report quoted by CNN.
Ruslan Tsarn, the suspects' uncle, told reporters the family was Muslim, but their religion had nothing to do with the attacks. He said the family was peace-loving, and"somebody radicalized [the suspects], but it's not my brother, who just moved back to Russia, who spent his life bringing bread to their table, fixing cars."
