ATKINSON, Neb. (AP) — A 26-year-old northern Nebraska man has pleaded not guilty to intentional child abuse that authorities say caused the death of his son at an Omaha hospital.

Michael Schroeder, of Atkinson, remains in Holt County Jail on $1 million bail. He’s accused of abusing his 8-month-old son, Kalium Ebsens.

A court affidavit filed by an Atkinson officer says the boy was taken to West Holt Memorial Hospital the night of Oct. 26 after the boy became unresponsive. The infant then was flown to an Omaha hospital, where he died the morning of Oct. 29. The officer said Schroeder acknowledged bumping the boy’s head a couple of times.

DENVER (AP) — Denver authorities say a driver had a medical emergency when he hit and injured four Denver police officers who were monitoring a student protest of the Ferguson, Missouri, grand jury decision.

Police Chief Robert White says one officer was critically injured and was in surgery. He says two of the other three were released from a hospital.

The driver of the vehicle was taken to a hospital for the medical issue. A witness told The Denver Post that he saw a Mercedes run onto a sidewalk and hit the officers before crashing into a Taco Bell.

White says the officers were on hand for the safety of hundreds of East High School students who walked out of class Wednesday and marched to the state Capitol to protest the jury’s decision.

OMAHA, Neb. (AP) — An Omaha man has been given probation for his involvement in a car crash earlier this year that killed his girlfriend.

A judge sentenced 26-year-old Nicholas Marescalco on Wednesday to five years of probation on a manslaughter charge.

Prosecutors said Marescalco was driving when he intentionally crashed the vehicle into a pole in July. Twenty-five-year-old Sharlee Arnett, a passenger in the car, was killed.

The judge told Marescalco he issued probation instead of a short prison sentence so he could monitor him longer.

OMAHA, Neb. (AP) — Officials for a public school district in Omaha say a high school student brought brownies laced with a laxative to school.

Millard Public Schools spokeswoman Rebecca Kleeman says the student brought the brownies to Millard North High School on Nov. 25.

Several students ate the brownies and got sick.

Kleeman says the student was ticketed by police on suspicion of assault and was disciplined by the district for violating its code of conduct. She did not elaborate.

OMAHA, Neb. (AP) — A 20-year-old woman has been accused of stabbing a man in Omaha.

Police say 20-year-old Vanessa Kasun faces charges of use of a weapon to commit a felony and first-degree assault. Court records do not list an attorney.

Kasun is accused of stabbing and slashing a man Tuesday night following a fight between the two and Kasun’s boyfriend. The man was taken to a local hospital in critical condition but with non-life-threatening injuries. He was in serious but stable condition Wednesday morning.

Police say Kasun fled the scene after the attack. She was later arrested.

OMAHA, Neb. (AP) — A report says that nearly $4 billion would have been part of the regional economy in 2012 if racial gaps in income, employment and education were closed in the Omaha area.

The Metropolitan Area Planning Agency released its “Heartland 2050 Equitable Growth Profile” on Tuesday. It says minorities, which help drive Omaha’s population growth, are less likely to have high school degrees and skills needed for the modern workforce.

The report offered several suggestions to decrease the disparities between races. Among the recommendations were for the city to provide more job training programs and invest in public infrastructure to create jobs.

MAPA’s executive director says the costs of inequity will increase unless the racial gaps are closed.

LINCOLN, Neb. (AP) — A Lincoln coalition of civic and school leaders is being formed to address several student suicides in recent weeks.

Five teenagers have committed suicide so far this year, with three in the past three weeks.

On Monday, a 14-year-old student attempted suicide by jumping from a downtown building. A Lincoln police officer says he suffered several broken bones and is in critical condition.

The superintendent of Lincoln Public Schools says the deaths are a community problem and announced the creation of the coalition Tuesday. He wants to gather teachers, law enforcement officials, mental health leaders and families to talk about the issue and look for solutions.

The district also asked parents with children in middle and high school to talk to their children about suicide.

A Tuesday, Dec. 2, crash between a semi and a pickup injured a Thurston County Sheriff’s Deputy. The crash occurred at the crest of a hill on Highway 94 about three miles east of Pender in Thurston County.

Around 4:15 p.m., Tuesday, Dec. 2, the semi was crossing Highway 94 from a county road, when a 2013 Ford pickup driven by a Thurston County Sheriff’s Deputy crested the hill. The deputy attempted to avoid the crash but was unable to and the pickup struck the rear of the semi.

Deputy Nicholas Carlson, 23, of Emerson, suffered a leg injury and was transported to Mercy Hospital in Sioux City, Iowa. The driver of the semi, Zachery Tietz, 25, Bancroft, was not injured.

The accident remains under investigation.

OMAHA, Neb. (AP) — A Nebraska woman has been sentenced to 50 to 70 years in prison for fatally shooting a woman in the chest at a house party while high on methamphetamine.

31-year-old LaToya Ross was sentenced Tuesday for killing 41-year-old Dawn Truman at an Omaha house party in December 2013. Authorities say Ross accused Truman of being a “snitch” and that the bullet pierced her heart. Truman died at the scene.

Ross confessed to the killing once she was sober. She pleaded no contest to a reduced charge of second-degree murder in a deal with prosecutors.
