But he was loyal and never hinted at plans for violence, according to friends and former classmates.

Several major American colleges and universities have made headlines for things they would have done anything avoid.

Despite his attempt to throw off police looking for him, a patrolling sheriff's deputy spotted him and the gunman killed himself.

An investigation is under way into the fatal shootings today at Virginia Tech.

The gunman who killed a police officer Thursday after being pulled over in a traffic stop at Virginia Tech is believed to be dead, a law enforcement official told The Associated Press.
