"Around school, Tsarnaev was known as a guy who loved soccer and brushed off invitations to join the Muslim Student Association on campus, according to its president, Ahmad Nassri.
I was trying to pull him into the group, Nassri said. He didnt really want it. I think he attended one meeting. He defined himself as a Muslim but if you asked him if he was religious he would say, No.
Bettencourt said he had found disturbing the casual way Tsarnaev chatted about the bombings during his gym workout.
I dont know how he talked about it. I dont know what was going on in his head, Bettencourt said"
