UNADILLA, Neb. (AP) — The National Weather Service has issued a tornado warning for Otoe County in southeastern Nebraska.

The service said a little after noon on Wednesday that a storm capable of producing a twister was situated near Unadilla, about 23 miles southeast of Lincoln. The thunderstorm was dropping hail and heading northeast, toward Cass County and over to western Iowa.

The storm is part of a massive system that moved into Nebraska earlier Wednesday after dropping a dozen inches of snow in the Colorado Rockies. High winds and blowing snow have caused several accidents in western Nebraska, but no injuries have been reported.

WILBER, Neb. (AP) — Authorities say one person has been killed in a collision on a southeast Nebraska highway.

The accident occurred just before 8 a.m. Tuesday on Nebraska Highway 103, about two miles north of Wilber.

Saline County emergency management coordinator B.J. Fictum says the head-on collision involved a car and a van. The names of those involved and other information about the crash have not been released.

YORK, Neb. (AP) — A 39-year-old man has pleaded not guilty to charges related to a York standoff with officers.

Sean Hoffman, of Waco, made his pleas on Monday to felony charges of assault, terroristic threats and use of a firearm. His trial is set to begin on March 15.

Court documents say Hoffman broke into a York man’s home and assaulted him on Aug. 25. Police later found Hoffman at his parents’ home in York, where he refused to come out. Officers entered the house and took him into custody after several hours.

OMAHA, Neb. (AP) — Omaha police honored a nursing student for her actions last month to help an officer who had been severely beaten at a gasoline station.

Police gave Tiffany Joseph a plaque and check for $1,625 raised through donations to police officers associations.

Police Chief Todd Schmaderer says Joseph’s actions “represent everything that is good about our community,” when she helped officer Tom Arrance on Oct. 7.

Witnesses say Arrance was surprised by a man who hit him so hard, it broke the officer’s nose, cheekbone and the bones around his eye. Joseph, a part-time nursing student, tried to stop the bleeding and stayed with Arrance.

Joseph met Arrance at the ceremony and expressed relief he was OK.

Police have charged a man with the beating.

OMAHA, Neb. (AP) — What has been known as the Omaha police crime lab now is called the forensic investigations unit.

The unit develops and examines latent prints, compares spent shell casings and takes photographs.

Police Lt. Darci Tierney said the new name is more correct because the civilian technicians don’t have a lab to analyze some of the evidence they collect. Tierney says outside labs handle that work.

Tierney says it’s important to have the name reflect “more of what we do rather than what we don’t do.”

ORLANDO, Fla. (AP) — A new study suggests that wealthy people are more likely to get on multiple waiting lists and to score an organ transplant, and less likely to die while waiting for one.

Donor organs are assigned based on medical need, time on a waiting list and other factors. Patients can get on waiting lists in more than one area but often must pay for new tests to qualify, and travel on short notice if an organ becomes available.

The new study looked at records for more than a decade and found that multiple-listed patients had higher transplant rates, lived in higher-income zip codes and were more likely to have private insurance versus Medicaid.

Results were discussed Monday at an American Heart Association conference in Orlando.

LINCOLN, Neb. (AP) — A fire has burned through a garage and damaged another nearby home in Lincoln.

Firefighters were called to the residence around 2:15 p.m. Sunday. They cut a hole through the roof of the burning garage to ventilate the fire upward. The garage’s interior, the outside wall and a partial section of the attic were damaged.

Battalion Chief Brad Thavenet says the fire may have been started by a warm motor of a lawn mower burning a pile of nearby leaves or leaves still in the leaf bag. The garage’s owner was doing yard work and left the lawnmower unattended shortly before the fire began.

Heat from the fire burned through the vinyl siding of a next-door home.

An investigation is ongoing.
