OMAHA, Neb. (AP) — Omaha police say they’ve arrested a man who shot and critically injured a man in a park.

Officer Michael Pecha says 23-year-old Carl Johnson Jr. was arrested Sunday for the Saturday shooting at Orchard Park. He is charged with first-degree felony assault and use of a weapon to commit a felony in the shooting of 23-year-old Josh Hintz.

Police say Hintz was shot during an argument involving a large group of people. They say Hintz was critically injured and taken to Creighton University Medical Center.

A hospital spokesman told the Omaha World-Herald Sunday that no information about Hintz’s condition was being released.

Online jail records didn’t indicate an attorney for Johnson.

LINCOLN, Neb. (AP) — The pedestrian bridge linking the Pinnacle Bank Arena to nearby parking lots reminds people they’re in Lincoln and provides links to famous Nebraskans.

The word Lincoln is spelled out in big block letters on both sides of the bridge, which is lit up at night. The two-block-long walkway has 14 aluminum panels on its sides, offering pedestrians a chance to see a collection of virtues and values linked to quotes from famous Americans with Nebraska ties. Among those listed is President Gerald Ford, who was born in Omaha, and billionaire investor Warren Buffett.

The group picking the virtues and quotes made sure there was diversity in the people selected. Copyright issues were checked and permission for use was obtained from various foundations and estates.

LINCOLN, Neb. (AP) — A 30-year-old man has pleaded not guilty after being found competent to stand trial in a Lincoln slaying.

LaRon Branch made his pleas Friday in Lancaster County District Court. He’s charged with second-degree murder and use of a deadly weapon.

In May a judge had ordered Branch to undergo a psychiatric evaluation to see whether he is fit to stand trial in the slaying of Jarvis Long. Long was stabbed to death on Jan. 16 in Lincoln’s Peter Pan Park.

LINCOLN, Neb. (AP) — Nebraska police say they’re investigating two pizza delivery robberies in as many days after teenagers stole two pizzas, cinnamon sticks, cash and a cellphone.

The Lincoln Police Department says a Topper’s Pizza delivery man was robbed Saturday night. He tells police that three male teenagers were hiding in the bushes near a home. He says one pointed a gun at him and they fled on foot after the robbery.

Police say a Pizza Hut delivery woman was robbed at gunpoint Friday night by three male teenagers a few blocks away from the other location. They say the robberies are similar but they’re not sure whether the two are related.

Police say they’re searching for the teens.

FERGUSON, Mo. (AP) — Missouri Gov. Jay Nixon is lifting a curfew while ordering the National Guard to help restore order in a St. Louis suburb that has seen sometimes violent protests since the fatal police shooting of an unarmed black teenager.

Nixon deployed the Guard Monday following an overnight clash between armored police and what he called “a violent criminal element intent upon terrorizing the community.”

The unrest followed the Aug. 9 shooting of 18-year-old Michael Brown by Ferguson police officer Darren Wilson, who is white.

The neighborhood has been under a midnight-to-5 a.m. curfew the past two days, after Nixon declared a state of emergency. The governor says in a statement that the curfew is now lifted.

He says the Guard will be under the direction of the state Highway Patrol.

LINCOLN, Neb. (AP) — Nebraska police say one person is dead and another is injured in a one-person rollover.

Lincoln Police Cpt. David Beggs says the crash happened Sunday evening. Police say the driver lost control of the vehicle and hit a bridge railing. It’s unclear what caused the crash.

Police say the driver was taken to the hospital. The passenger died at the scene.

They haven’t released their names or ages.

DAVID CITY, Neb. (AP) — More than 1,000 people attended the funeral for Butler County Sheriff Mark Hecker.

The 53-year-old Hecker was remembered Saturday for his positive attitude and his commitment to law enforcement. The funeral was held in the gymnasium of Aquinas Catholic High School in David City.

Hecker died last week after suffering a heart attack on Aug. 8.

Rev. David Palomaki of the Redeemer Lutheran Church says Hecker knew early on that he wanted to be involved in law enforcement and help people get on the right track.

Former Platte County Sheriff Jon Zavodil worked with Hecker. He says Hecker’s upbeat attitude made a difference in many people’s lives.

WASHINGTON (AP) — Sometime in elementary school, you quit counting your fingers and just know the answer.

Now, scientists have put youngsters into brain scanners to find out why, and watched how the brain reorganizes itself as kids learn math.

The take-home advice: drilling your kids on simple addition and multiplication may pay off.

Healthy children start making that switch between counting to what’s called fact retrieval when they’re 8 years old to 9 years old, when they’re still working on fundamental addition and subtraction.

How well kids make that shift to memory-based problem-solving is known to predict their ultimate math achievement.

PENDER, Neb. (AP) — Thurston County’s jail needs to be replaced after nearly 100 years of use, but county officials are having trouble agreeing on where it should be built and how to pay for it.

The northeast Nebraska county is considering asking voters to approve a $7.5 million bond issue in November for a new 48-bed jail.

The current jail has 25 beds in three large cells, so there isn’t any way to separate inmates by the seriousness of their crimes. Sheriff Shelly Perez says the jail isn’t all that secure either.

A consultant recommends building a new jail in Pender, but some county board members want to build it 13 miles away in Walthill because that site is supported by the area’s Omaha and Winnebago tribes.
