WAKEFIELD, Neb. (AP) — The discovery of a suicide on school property in northeast Nebraska forced a lockdown lasting several hours.

The K-12 Wakefield Community Schools building was locked down for several hours Wednesday while the Dixon County Sheriff’s office investigated. Normal operations resumed before the end of the school day.

The sheriff’s office said in a statement that a 20-year-old man was found with a self-inflicted gunshot wound Wednesday morning.

Superintendent Mark Bejot said a teacher noticed a running car parked on a soccer field near the school Wednesday. When he investigated, Bejot found the man dead inside the car.

The man’s identity wasn’t immediately released, but officials say he wasn’t a student.

Wakefield is a small city of about 1,400 people about 35 miles southwest of Sioux City, Iowa.

CONWAY SPRINGS, Kan. (AP) — An earthquake with a preliminary magnitude of 4.8 has shaken parts of Kansas and Oklahoma.

The U.S. Geological Survey says the quake struck around 3:40 p.m. Wednesday. It had an epicenter about 8 miles south of Conway Springs, which is a town of about 1,200 people about 30 miles southwest of Wichita. It wasn’t immediately clear how much damage the quake may have caused.

The southern part of Kansas has been experiencing an upsurge in earthquakes this year. A panel commissioned by Kansas Gov. Sam Brownback found there wasn’t enough evidence to link the temblors to oil and gas exploration. The panel is recommending more study and the installation of more monitoring stations.

LINCOLN, Neb. (AP) — Officials in a southeastern Nebraska county say they have enough markers to place one on every war veteran’s grave in Calvary Cemetery.

Marine veteran Richard Zierke asked Lancaster County officials in January to purchase almost 600 brass markers for the graves.

Gary Chalupa, the county’s veterans services officer, says the county can now purchase them and expects to buy up to 600 metal alloy flag holders to be fastened to headstones.

Officials usually place brass flag holders to mark veteran graves.

Chalupa says that brass flag holders cost almost $30 each. He says the county ordered the metal alloy version at $10 each to stretch available funds.

MADISON, Neb. (AP) — A northeast Nebraska prosecutor helped deputies subdue a defendant during a courtroom melee.

The incident erupted Monday morning during a hearing in Madison County District Court in Madison.

Twenty-three-year-old Taylor Pass began screaming at a judge after the judge sent Pass back to jail because the man who’d posted bond for Pass wanted his money back.

Norfolk defense attorney Doug Stratton says County Attorney Joe Smith joined deputies in gaining control of Pass, who eventually was taken from the courtroom.

After the incident, Judge Mark Johnson raised Pass bail amount to $75,000 from $20,000.

Pass is scheduled for a February trial on theft and threats charges.
