The 17-year-old gunman who opened fire at his Nebraska high school, killing an assistant principal, had been removed from the school hours earlier for driving on its football field, police said Thursday.
Robert Butler Jr. was escorted out of Millard South High School in Omaha Wednesday morning after meeting with Assistant Principal Vicki Kaspar. A few hours later, Butler returned and shot both Kaspar and the school's principal before fleeing the school and killing himself, police said.
Butler, who was the son of an Omaha police detective, had been cited on New Year's Day for criminal trespassing after driving his car on the school's football field and track, police said. Wednesday was the first day back at school after the holiday break.
Kaspar, 58, died at Creighton University Medical Center Wednesday evening, hours after the shooting. Principal Curtis Case, 45, was in serious but stable condition. Butler, who had transferred in the fall to Millard from a high school in Lincoln, about 50 miles southwest of Omaha, was found dead in car about a mile away from school.
On the same day as the shootings, Butler posted a rambling message on Facebook about his unhappiness with his new school, but he didn't supply many details. Instead, the expletive-laced note predicted Butler's friends would hear about the "evil things" he did.
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." The post ended with "goodbye."
A former classmate of Butler's from Lincoln confirmed the Facebook post to The Associated Press and provided AP with a copy of it.
