Police spokesman James Shade says investigation continues as detectives work to identify the suspect.

PAPILLION, Neb. (AP) — A 7-year-old girl has died after being injured in a Sarpy County collision that occurred a week ago with her big sister at the wheel.

Nebraska Medical Center spokesman Taylor Wilson said Tuesday that Madelyne Hughes died around 11 p.m. Monday. The little girl was taken to the Omaha hospital on Jan. 13, after an accident on U.S. Highway 75.

Sarpy County authorities say 17-year-old Taylor Hughes and Madelyne were in a northbound sport utility vehicle that was struck by a southbound van when Taylor Hughes tried to turn west onto Platteview Road south of Bellevue.

The van driver was hospitalized with a broken ankle. Taylor Hughes was treated for an arm injury. She was cited for failing to yield.

LINCOLN, Neb. (AP) — A Nebraska doctor whose medical team treated three Ebola patients last year will attend President Barack Obama’s State of the Union address.

Dr. Philip Smith, medical director of Nebraska Medicine’s Biocontainment Unit, was invited as a guest of U.S. Sen. Ben Sasse. Obama is scheduled to speak Tuesday starting at 8 p.m. Central Time.

Smith leads the specialized Nebraska team that treated three Ebola patients last year.

Nebraska’s biocontainment unit is the largest in the country and one of just four facilities in the United States equipped and trained to handle Ebola and other highly contagious diseases. Between September and November of last year, doctors in Nebraska successfully treated Dr. Rick Sacra and freelance journalist Ashoka Mukpo.

Sasse praised the medical staff for its courage, precision and hard work.

NORFOLK, Neb. (AP) — Police say a 29-year-old woman from Norfolk is in custody after hitting another person in the face with a DVD player and scratching officers who tried to arrest her.

Officers were dispatched to an apartment building Sunday night.

When they arrived, officers say they found the 29-year-old being pinned down by a second woman. Police told the second woman to get off the 29-year-old, and when she did, officers say the 29-year-old struck her with a DVD player that was on the ground.

Police tried to handcuff the 29-year-old, who they say struggled and resisted officers’ attempts to take her into custody.

She was arrested for second-degree domestic assault, third-degree assault on a police officer, resisting arrest, obstructing a police officer and disturbing the peace.

The Gage County Sheriff’s Office identified him as 33-year-old Jason Meisenhelder, of Beatrice. The incident occurred early Sunday morning on Pickrell Road, about a mile north of Pickrell.

It’s unclear how fast the van was moving when Meisenhelder jumped out the rear door. Authorities say he died later at a Lincoln hospital.

LINCOLN, Neb. (AP) — A new behavior modification program is changing the lives of some parents and their children in Lincoln Public Schools.

The program is aimed at students whose behavior problems have disrupted classrooms and made it impossible for the students to learn. The program employs a strict behavioral code, positive reinforcement for good behavior and provides opportunities students can take – or lose — depending on behavior and academic performance.

In May the district signed a three-year contract with Specialized Education Services in Pennsylvania to implement its program, which costs $290,000 for the first year.

Two consultants from Success Schools have worked with the Lincoln students and trained 16 teachers, as well as administrators and therapists.

Police say Reger had been driving north on 132nd Street Monday when a southbound car turned east, into his path.

The accident is still being investigated. Police say charges are pending against the car driver.

OMAHA, Neb. (AP) — More elected officials are urging a Nebraska State Board of Education member to resign after derogatory comments about President Barack Obama appeared on his blog.

Four Omaha Board of Education members on Monday joined the list of those calling on Pat McPherson to step down. The board members said in a statement that “there is no place for racist commentary” in politics.

Others calling for his resignation include Nebraska Gov. Pete Ricketts and Republican U.S. Sen. Ben Sasse.

McPherson’s blog included repeated references to Obama as a “half breed.” McPherson has said he didn’t write the posts and disavowed them before removing them last week.

McPherson did not return calls from the newspaper Monday and said last week he would have no further comment.

LINCOLN, Neb. (AP) — A 31-year-old man is facing several charges after fleeing across Lincoln in a stolen car at speeds over 100 mph.

Nebraska State Patrol spokeswoman Deb Collins says the pursuit began around 12:30 Monday after a stolen Ford Fusion was spotted by the patrol’s helicopter.

When the driver fled, the trooper ended the pursuit because of public safety concerns. The helicopter followed the Ford from above as it drove erratically from south of Lincoln to Interstate 80.

The fleeing driver forced several other vehicles off the road as he crossed Lincoln.

State troopers resumed their pursuit after the driver reached I-80. Then troopers disabled the fleeing vehicle after the driver exited near the Lincoln airport.

The fleeing driver was treated for a minor arm injury before being taken to jail.
