OMAHA, Neb. (AP) — A 54-year-old man has been convicted of murder and manslaughter in the shooting deaths of two people in Omaha.

A Douglas County District Court jury found Michael Nolt guilty Wednesday of first-degree murder in the Oct. 10, 2015, slaying of Malquan King and of manslaughter in the slaying of Arelius Hassell. He was convicted of several other charges but acquitted of attempted murder. Nolt is scheduled to be sentenced Jan. 17.

Police say Nolt told his mother he’d killed some people in a botched robbery.

OMAHA, Neb. (AP) — School officials are trying to quell student behavior problems at an Omaha middle school, where enrollment has nearly doubled with the addition of sixth-graders this year.

Omaha Public Schools Superintendent Mark Evans and two school board members visited Nathan Hale Middle School on Tuesday in response to complaints from parents and staff about the behavior.

Snow says he has talked to teachers about students throwing things, running in the halls and interrupting class. School board member Justin Wayne says teachers are also overwhelmed.

School district spokeswoman Monique Farmer says the problem stems from a small number of students who disrupt the school day.

Omaha Education Association president Bridget Donovan says officials are struggling to keep teachers from leaving the school.

The school district says it’s adding more security guards and two student deans to the middle school’s staff.

OMAHA, Neb. (AP) — Residents walking around Omaha might notice a few messages chalked on the sidewalks urging people to vote.

The League of Women Voters has been busy painting sidewalks across town.

Two chalk messages — “Go Vote, Omaha!” and “Be a Voter!” — were stenciled at high traffic areas across the city. Organizers say the messages are intended to remind people of how important their votes on Nov. 8 are.

Metropolitan Community College art students designed the stencils used in the project.
