Teen kills vice principal in Nebraska high school

OMAHA, Neb. (AP) - The son of a police detective opened fire at a Nebraska high school Wednesday, fatally wounding the assistant principal and forcing panicked students to take cover in the kitchen of the building just as they returned from holiday break.

The gunman, who had attended the school for no more than two months, also wounded the principal before fleeing from the scene and fatally shooting himself in his car about a mile away.

Authorities declined to speculate about why the suspect, identified as Robert Butler Jr., targeted the administrators.

Vice Principal Vicki Kaspar, 58, died at a hospital hours after the shooting, police said. Principal Curtis Case, 45, was listed in stable condition.

"I can't think of a nicer person. I can't see how anyone would be cross with her," John Manna said of Kaspar earlier Wednesday. Manna said he knew Kaspar because his older son graduated from high school with her son in 1996.

Butler, 17, had transferred in November from a high school in Lincoln, about 50 miles southwest of Omaha.

In a rambling Facebook post filled with expletives, Butler warned Wednesday that people would hear about the "evil" things he did and said the school drove him to violence. He wrote that the Omaha school was worse than his previous one, and that the new city had changed him. He apologized and said he wanted people to remember him for who he was before affecting "the lives of the families I ruined."
