As Boston reeled, younger bombing suspect partied
CNN) -- As the world hunted him, the younger brother suspected in the Boston Marathon bombings acted like any other college sophomore.
Dzhokar Tsarnaev, 19, was on the campus of University of Massachusetts-Dartmouth every day after the attack until late Thursday, a university official told CNN. Tsarnaev attended classes and dorm parties and went to the gym while the rest of Boston came to a tense standstill.
A student at the school told The Boston Globe that she saw Tsarnaev at a party Wednesday night that was attended by some of his friends from intramural soccer.
"He was just relaxed," she said, asking the paper not to print her name.
Another UMass Dartmouth student said he talked about the bombing with Tsarnaev for several minutes Tuesday while they were working out at the gym. Tsarnaev seemed normal, perhaps a little tired, Zach Bettencourt told CNN.
Bettencourt said he told Tsarnaev something about the bombing, to the effect of, "You hear about this kind of thing happening in Iraq and Afghanistan, but not here."
"He was like, 'Yeah, tragedies happen like this all the time and it's sad,' " Bettencourt said, adding he had no inkling about anything suspicious with Tsarnaev, whom he described as a nice guy.
