Washington teacher pleads for help in 911 tapes

Frantic 911 recordings are giving new insight to the moments just after a shooting at a suburban Seattle high school, reports CBS News John Blackstone.

In one call, a teacher told the dispatcher there was "blood everywhere" at Marysville-Pilchuck High.

"911, we have a shooting, Marysville-Pilchuck High School cafeteria, the shooter... We have many injured, Marysville-Pilchuck High School, we need emergency right away! My name is Megan Silberberger. I'm a teacher."

The first-year social studies teacher raced toward the gunfire in the cafeteria, not away from it.

Silberberger: "I am in the cafeteria. I have the shooter, one shooter, blood is everywhere, I do not see the gun."
Dispatcher: "Do you have a description of the shooter?"
Silberberger: "I'm looking at him, I need help, I need help now!"

Silberberger was looking at 15-year-old gunman Jaylen Fryberg, shortly after he opened fire on five of his friends and fellow classmates, four of whom died.

Frantic phone calls from worried parents flooded 911 dispatch.

One parent called in:

"My daughter just texted me that there is shots fired at her high school. My daughter is not following lockdown directions and she and some other kids have run from their classroom."

As students fled the high school, Silberberger stayed inside the cafeteria with the critically-injured students and the gunman -- who turned the weapon on himself.

Silberberger: "I tried to stop him before he shot himself, I do not know his name."
Dispatcher: "Okay, you said he has shot himself?"
Silberberger: "He shot himself."

Dozens of calls made by students, staff and parents in the first hour after the shooting have not yet been released.

But these new audio recordings are providing insight into those first terrifying moments after the shooting began.
