Barry opened fire on his algebra class killing classmates Arnold F. Fritz, and Manuel Vela and teacher Leona D. Caires.  Natalie Heinz, sitting next to the boys, was shot in the stomach and right arm.  Gym teacher Jon M. Lane rushed in, knocked the rifle away from Barry and wrestled him to the floor to end the rampage. Barry was carrying a hunting rifle and two handguns.

Had told five friends that he planned to bring the rifle to school.

Poems written by Barry prior to the incident;

A sullen life style gripped with pain

The feeling of murder

The heat of hate and the love of death

*****

''Murder '' It's my first murder

I'm at the point of no return

I look at his body on the floor

Killing a bastard that deserves to die

Ain't nuthin' like it in the world But he sure did bleed a lot
