Berrendo Middle School in Roswell, New Mexico, re-opens today.
This happens as we're hearing , for the first time , the 911 calls from inside the school that describe the terrifying moments after police say a 12-year-old opened fire and severely wounded two classmates.
A law enforcement source tells CNN the shooter had a journal at home that described his plans.
And the source says the boy told some students in the gym to get out before he fired his sawed off shotgun.
The motive is still not clear.
The parents of the boy say the incident has left them heartbroken.
And they offered condolences to the families of the victims.
Today, counselors will be on site at the school to help.
