These images show Tamerlan Tsarnaev, identified by investigators as Suspect 1 in the Boston Marathon bombings. The older of the two brothers sought by law enforcement, the 26-year-old was killed in a firefight with police. He was born in Russia, and became a permanent legal resident of the United States in 2007, law enforcement officials said.

Tamerlan Tsarnaev's brother, Dzhokhar, 19, remained at large on Friday.

The suspect in the black hat in photos released by the FBI, Tsarnaev studied at Bunker Hill Community College in Boston and aspired to become an engineer, according to a profile in a Boston University graduate magazine in 2010. He wanted to box for the U.S. Olympic team, according to the profile.

According to an article in The Lowell Sun newspaper, Tsarnaev boxed in a 2004 tournament as part of a program called Golden Gloves. “I like the USA,” he told the newspaper at the time.

In the Boston University magazine photospread, Tsarnaev is shown working out at the Wai Kru Mixed Martial Arts Center in Boston, Mass. He is quoted as saying he loves the movie Borat, and describes himself as a Muslim who does not smoke or drink. “I don’t have a single American friend,” he said. “I don’t understand them.”
