Boston Marathon bombing suspect Dzhokhar Tsarnaev was at the University of Massachusetts Dartmouth this week after the explosions killed three people and wounded more than 180 others, his classmates told The Associated Press on Friday.
The university evacuated its campus Friday morning after confirming that Tsarnaev is a registered student there.
His father told The Associated Press that his 19-year-old son was studying medicine.
Sonia Ribeiro, a 19-year-old was in a philosophy class with Tsarnaev said, "He was laid back. I would never expect this at all from him," she said.
One professor says he worked with Dzhokhar on research work of his Chechen roots.
Law enforcement officials and family members identified the suspects as Dzhokhar Tsarnaev and his older brother Tamerlan, two ethnic Chechen brothers who had lived in Dagestan. Tamerlan was killed in a shootout with police while Dzhokhar had escaped from authorities.
The school said in a statement that it evacuated campus "out of an abundance of caution," amid a manhunt for Tsarnaev.
