A former Hampton University student armed with three loaded handguns shot a dorm manager and a pizza delivery driver inside a school dorm early Sunday before turning the gun on himself, officials said.

All three survived, and a suspect was quickly arrested. A motive for the shooting was not clear.

The dorm manager, who was shot three times, had been released from a hospital on Sunday. The delivery driver and the suspect, age 18, remained in a hospital in stable condition, university officials said.
