The shooter interrupted his scheduled first period class and shot the victim, also a 16-year-old student who is now in critical but stable condition.

Both men were unarmed. The teacher had received gun emergency training that morning, according to officials. The shooter was using a .12 gauge shotgun. The officer usually posted to the school was not there today, according to officials, because he could not make it due to the weather.
