A Chicago boxer four years ago fought -- and beat -- one of the suspects of the Boston Marathon bombings.
Lamar Fenner, who died last year, battled Tamerlan Tsarnaev during the 2009 Golden Gloves National Tournament of Champions May 4, 2009 in Salt Lake City, Utah.
Fenner at the time was a junior at Leo Catholic High School, his former trainer, Mike Joyce, told the Chicago Sun-Times. Fenner died last year of a heart condition, Joyce said.
Tsarnaev, 26, was the subject of a photo essay titled "Will Box for Passport" that's since been taken offline. The information in the photo captions, however, indicated Tsarnaev fled his native Chechnya with his family in the early 1990s because of conflict there and lived for years in Kazakhstan before heading to the United States as a refugee.
But even after living in the U.S. for five years, Tsarnaev, who had aspirations to join the U.S. Olympic wrestling team, apparently felt alone.
"I don't have a single American friend," professional photographer Johannes Hirn quoted Tsarnaev as saying. "I don't understand them."
Tsarnaev was shot and killed by police early Friday morning. Tsarnaev and his brother, 19-year-old Dzhokhar A. Tsarnaev, are suspected of planting the bombs at the finish line of Monday's Boston Marathon. The blasts killed three people and wounded at least 170 others.
"I was flabbergasted by this whole thing. He was a very athletic, outgoing nice guy, very respectful," his trainer from 2008 to 2010, John Curran, told NBC News. "[He was] just the opposite of what you paint as a terrorist."
The younger Tsarnaev remained on the loose Friday afternoon and was the subject of a massive Massachusetts manhunt.
