On America's Newsroom this morning, we heard for the first time the 911 calls from inside a New Mexico school, where a 12-year-old boy wounded two classmates.

One student tells the 911 dispatcher he saw one of the victims and says "you probably need to hurry."

Without the heroic actions of a social studies teacher at Roswell's Berrendo Middle School, the attack could have been much worse.

The boy opened fire with a shotgun, but the teacher convinced him to put down the weapon.

Listen to the 911 calls above.
