Fall 2006

Tamerlan Tsarnaev enrolled as a part-time accounting student at Bunker Hill Community College in Boston. He took classes for only three semesters - fall 2006, spring 2007 and fall 2008. "He wasn't even close" to getting a degree, said Patricia Brady, a spokeswoman for the college.

Around 2007

May 2009

Tamerlan Tsarnaev competed in the Golden Gloves National Tournament of Champions in Salt Lake City, Utah. He lost his first bout.

July 2009

Tamerlan Tsarnaev was arrested after a woman identified as his girlfriend accused him of domestic abuse, a charge that was dismissed at a jury trial in 2010.

Sometime in 2009

Ruslan Tsarni, an uncle of the brothers, told CNN he first noticed a change in Tamerlan Tsarnaev's religious views in this time period. He said the radicalization of his nephew happened "in the streets of Cambridge."

2009 or 2010

Tamerlan married Katherine Russell, whose family lives in an upper middle-class neighborhood in North Kingstown, Rhode Island. Her father is licensed as an emergency room physician. The couple have a child named Zahara.


The Comment, the graduate student magazine of Boston University's College of Communications, ran a photo spread of Tamerlan Tsarnaev training at a boxing gym. He told the magazine "I don't have a single American friend. I don't understand them." He also said that he abstains from drinking and smoking: "God said no alcohol."

February 2010

Tamerlan Tsarnaev won the Rocky Marciano Trophy, an honor awarded to the heavyweight champion of New England.

Early 2011

Russia's Federal Security Service, or FSB, asked the FBI to investigate Tamerlan Tsarnaev out of concern that he has embraced radical Islam and was going to travel to Russia to join unspecified radical groups. The FBI interviewed Tsarnaev and his family members and examined his travel and Internet records.
