Hours later, police say Butler walked back into the Omaha school and opened fire on two administrators, fatally wounding Kaspar, an assistant principal known for her kindness and making it a priority to see that her students were successful.
"She cared about her job and she cared about doing it well. She cared about helping kids. She put in exhaustive hours. She never went home until the work was done," said Martha Bruckner, a superintendent in a neighboring district.
After shooting Kaspar, Butler wounded the principal and fled before killing himself.
