Boston marathon suspect Number 1 is an amateur boxer who was killed after a series of violent events in the Boston area early Friday morning, according to The Associated Press.
Tamerlan Tsarnaev, 26, died from gunshot wounds and injuries suffered in an explosive blast.
His younger brother, Dzhokhar A. Tsarnaev, 19, survived and escaped, leading authorities on a massive manhunt, according to The Associated Press.
The brothers' uncle, Ruslan Tsarni of Maryland, told The Associated Press that the men lived together near Boston and have been in the United States for about a decade. They traveled here together from the Russian region near Chechnya.
Tamerlan was an amateur boxer, listed as a competitor in a National Golden Gloves competition in 2009, The AP said.
A 2010 Boston University magazine article said Tsarnaev was training at Wai Kru Mixed Martial Arts Center in Boston.
"I don’t have a single American friend. I don’t understand them," Tsarnaev told the writer.
The article said Tsarnaev was studying at Bunker Hill Community College to become an engineer, but said he took the semester off to train for the Golden Gloves competition in hopes of being selected for the next U.S. Olympic Team and becoming a naturalized American.

-- Night of violence lead to Tsarnaev's death --
Authorities suspected the chaotic night of violence began with the robbery of a 7-Eleven in Cambridge. Then, at about 10:20 p.m. ET, a Massachusetts Institute of Technology campus police officer was repeatedly shot and found in his patrol car. The officer was pronounced dead at a hospital and police said two male suspects were believed to be responsible.
As dozens of local and state police spread across Cambridge, searching for the killers, two men reportedly carjacked a black Mercedes SUV. The carjacked driver was kept inside that SUV for about a half hour before being released at a gas station, the Middlesex District Attorney said.
Somewhere in the Watertown area, the vehicle was spotted and a police pursuit began. Gunfire was exchanged and police said explosives were thrown from the SUV.
During that shootout, a transit officer was shot. Richard H Donohue, Jr., 33, has been a transit officer for three years. He was in critical condition.
Tamerlan Tsarnaev was shot and later died at a hospital. Doctors there described him as arriving in a state of "dramatic arrest" and having a combination of blast and gunshot wounds.
Tamerlan Tsarnaev was allegedly wearing a black hat in surveillance photos released by the FBI Thursday afternoon. Dzhokhar Tsarnaev was allegedly wearing a white hat.
Dzhokhar A. Tsarnaev survived and escaped the shootout, leading authorities on a massive manhunt.
