Bombing suspect Dzhokhar Tsarnaev worked out, slept, partied after Boston Marathon attack

According to his friends, University of Massachusetts sophomore Dzhokhar Tsarnaev worked out, slept in his dowm room, and hung out with fellow students on the same day of the attack on the Boston Marathon, after the bombs went off. One student quoted in the Boston Globe who did not want to be identified said she saw Tsarnaev at a party on Wednesday night attended by some of his soccer team friends.

"He was just relaxed," she said.

Depending on which acquaintance's quote you read, the 19-year-old either sounds normal or creepy:

Emily DeInnocentis, 23, said Tsarnaev stood out to her because of some odd behavior, like spreading messy string cheese all over her couch, and picking up her cat and carrying it upstairs for no reason.

"We just didn't invite him over after that. How many people just pick up your cat and go upstairs?" she said.
