(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 while the rest of Boston came to a tense standstill.[/B]
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.
At the dorm where Tsarnaev lived, students joked Thursday as they viewed the FBI photos on television, a senior who lived in the suspect's dorm told The Boston Globe.
"We made a joke like, that could be Dzhokar," said Pamala Rolon. "But then we thought it just couldn't be him. Dzhokar? Never."
