OMAHA, Neb. (AP) - An angry online posting from the 17-year-old boy who opened fire at a Nebraska high school offers some clues about the violence.
Authorities say Robert Butler Jr. killed an assistant principal at Millard South High in Omaha and wounded the principal before later fatally shooting himself. Butler had been at the school for no more than two months.
Those who knew Butler are struggling to reconcile his final actions with their memories of a fun, outgoing student who sometimes got into trouble for talking in class.
Butler posted a rambling message on Facebook shortly before the shooting 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 was about to do.
