More and more details are coming out about Tamerlan Tsarnaev, the 26-year-old suspect in the recent Boston Marathon bombing who was killed late last night during a shootout with police. According to a new report, Tsarnaev was an aspiring boxer who once dreamed about boxing on the U.S. Olympic team. He even took part in a number of boxing tournaments, including a Golden Gloves tournament in 2009 where he lost to a boxer out of Chicago named Lamar Fenner.

At the time, he said that he wanted to try and use boxing to earn U.S. citizenship. However, he also offered up this chilling quote about his relationship with Americans.

"I don't have a single American friend," he said in a 2010 photo essay called "Will Box For Passport" in the Boston University graduate student magazine The Comment. "I don't understand them."

Tsarnaev's brother Dzhokhar, who reportedly wrestled in high school, was also involved in the Boston Marathon bombing and is still on the loose right now. Police are actively searching for him in the Boston area.
