An angry online posting from the 17-year-old boy who opened fire at a Nebraska high school, fatally wounding an assistant principal before later killing himself, offers some clues about why the son of a police detective turned violent a couple of months after transferring there.
As authorities sort out what may have led to the Jan. 5 shooting, those who knew Robert Butler Jr. are struggling to reconcile his final actions with their memories of the fun, outgoing student who liked to make jokes and sometimes got into trouble for talking in class.
The gunman, who had attended Omaha’s Millard South High 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.
“It’s just unreal,” said Robert Uribe, Butler’s stepgrandfather. Uribe said nothing appeared to be wrong when he last talked to Butler briefly a month ago. He said the polite young man he knew didn’t seem a likely gunman.
