Millard South reviewing security after shooting

An Omaha high school is considering security upgrades after a shooting that killed an administrator and wounded another.

Among the options under consideration at Millard South High School are requiring students to stay on campus for lunch, use mesh backpacks and carry an ID badge, as well as a ban on cell phones.

The suggestions follow a Jan. 5 shooting at the school. Authorities have said student Robert Butler Jr. used his father's handgun to fatally shoot assistant principal Vicki Kaspar and wound principal Curtis Case.

Kaspar had suspended Butler, whose father is an Omaha police detective, that morning for driving on the football field. Butler fled the school and killed himself. School officials will take input on the proposals over the next few weeks.
