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.

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.

OMAHA, Neb. (AP) — Alegent Creighton Health is planning to replace Creighton University’s hospital with a new $35 million medical facility in northeast Omaha.

The company announced the 90,000-square-foot project on Sunday. Construction is scheduled to begin next spring, and the facility should be ready in late 2016.

The new facility at 24th and Cuming Streets will offer outpatient and emergency services, but Alegent Creighton is planning to move most of Creighton University’s in-patient services to its Bergan Mercy Medical Center near 75th Street and Mercy Road in 2017.

Omaha City Councilman Ben Gray says he’s glad the company will maintain an emergency department in the area.

DAVID CITY, Neb. (AP) — The Nebraska State Patrol is investigating a rollover crash that killed a 33-year-old woman this weekend.

Authorities say the accident happened around 11 a.m. Saturday near the intersection of Nebraska Highway 92 and County Road O south of David City.

Jessica Fiala of David City lost control of her vehicle before it rolled, and she was killed in the crash.

Investigators couldn’t determine immediately what caused Fiala to lose control of the vehicle.

Police in Lincoln are asking for the public’s help in locating a missing 9-year-old boy.

According to police, Jaquan Sidney was last seen at around 1:30 a.m, Sunday, at his home.

Jaquan was last seen wearing a white shirt with animal print, grey sneakers, and blue and white checkered shorts.

Authorities say Jaquan, a black male, is 4’5” tall, and weights about 75 pounds.

If you have any information on his whereabouts, contact the Lincoln Police Department at 402-441-6000, or local law enforcement.
