Tamerlan Tsarnaev, one of the Boston Marathon bombing suspects, was the subject of an April 2009 photo essay that appeared in a graduate school magazine at Boston University. According to the article, he had hoped to become a naturalized American and make the U.S. Olympic boxing team. Authorities say an overnight shootout with police left him dead on April 19, 2013.
