OMAHA, Neb. (AP) — The defense has begun its case in the trial of a former doctor accused of killing four people with ties to an Omaha medical school.

Defense attorneys for Anthony Garcia called several witnesses Thursday, including an expert who testified that a gun magazine found at the home of Dr. Roger Brumback and his wife, Mary, showed extensive wear and did not appear to be new.

The testimony is intended to counter prosecutors’ assertions that the magazine was part of a handgun Garcia had purchased two months before the Brumbacks were killed in 2013.

Prosecutors say Garcia killed the Brumbacks, as well as the 11-year-old son of another Creighton University School of Medicine faculty member, Dr. William Hunter, and the family’s housekeeper in 2008.

OMAHA, Neb. (AP) — Authorities say a wounded man struck a school bus as he was driving to an Omaha hospital.

The shooting occurred around 4:30 p.m. Wednesday in northeast Omaha. Police say 25-year-old Jestun Haynie was sitting in the car in a driveway when someone in another vehicle drove by and shot him. He was about two miles from the shooting site when his car hit the school bus. Police say the bus driver and none of the children were injured.

Haynie was treated at Creighton University Medical Center and then taken to jail on an unrelated warrant and on suspicion of traffic violations. Online court records don’t list the name of an attorney who could comment for Haynie.

DENISON, Iowa (AP) — Authorities say a 51-year-old man accidentally shot himself on his way into a western Iowa field to hunt deer with his wife.

The shooting occurred around 5 p.m. Monday in southern Crawford County. The Iowa Natural Resources Department says Daniel Gehling, of Denison, was adjusting the handgun in his waistband when it went off. The bullet struck one of his thighs. The department says his wife, Carolyn, called for help and applied pressure on the wound to stanch the bleeding.

Daniel Gehling was taken to Crawford County Memorial Hospital in Denison for treatment and then flown to an Omaha, Nebraska, hospital for surgery.

GRAND ISLAND, Neb. (AP) — Authorities in south-central Nebraska have captured a man sought in a Texas homicide.

The U.S. Marshals Service says 30-year-old Jose Rivera, of Houston, was arrested without incident Tuesday night in Grand Island. He’s suspected in a fatal shooting during a January 2015 robbery at a convenience store in Houston. Authorities say a multiagency task force developed information that Rivera was at the Grand Island address where he was picked up.

Online records said Rivera remained in Hall County Jail on Thursday morning. It’s unclear whether Rivera has attorney who could comment on his behalf and whether Rivera will fight extradition to Texas.

RICHLAND, Neb. (AP) — Authorities say a car driver has been killed in a Colfax County collision with a sport utility vehicle.

The crash occurred around 6 a.m. Thursday, about three miles east of Richland on U.S. Highway 30. The Colfax County attorney’s office says a mechanical problem caused the eastbound SUV to go out of control, cross into oncoming traffic and hit the car head-on.

The car driver was pronounced dead at the scene and a passenger was taken to a hospital. The SUV driver also was hospitalized.

Authorities haven’t released the names of those involved.

OMAHA, Neb. (AP) — A 56-year-old man has been imprisoned for killing his Omaha neighbor.

Robert Inman was sentenced Tuesday to eight to 10 years in prison. He’d pleaded no contest to a manslaughter charge in the death of 48-year-old John Hanes. The two lived near each other at a mobile home park.

Prosecutors say Hanes took a meal of pot roast, potatoes and carrots to Inman’s home early in the morning on Aug. 29, 2015, in hopes of partying. But that pre-dawn disruption of their sleep angered Inman and his roommate. Prosecutors say a fight broke out, and Inman put Hanes in a chokehold to subdue him.

Inman says he called 911 later after realizing Hanes wasn’t breathing.

OMAHA, Neb. (AP) — A series of six layoffs will reduce the workforce at the Omaha Public Power District’s Fort Calhoun nuclear plant to as few as 300 employees.

There are currently 570 employees on site. The layoffs will occur over the next 20 months as part of the decommissioning of the plant, which will permanently cease power operations Oct. 24.

The first round of cuts is scheduled around Nov. 1, and the next round is set for the first quarter of 2017.

Mary Fisher, senior director of decommissioning for Fort Calhoun, told regulators Tuesday that employees are aware that layoffs beyond 2017’s first quarter could happen sooner or later than called for in the preliminary plan.

The decommissioning process includes disassembly and decontamination of equipment, which can take decades.

GRAND ISLAND, Neb. (AP) — The Hall County Board of Supervisors has approved a nearly $75,000 settlement with a former county corrections department employee whose lawsuit accused jail managers of sexual harassment and unfair treatment of female employees.

A lawsuit was filed on behalf of Sgt. Debb Rea in May saying her civil rights were violated by former corrections director Fred Ruiz and assistant director Jimmy Vann. According to the lawsuit, female employees were subjected to harsher discipline and referred to in an offensive manner.

Ruiz and Vann were fired by the board in August 2015 after Rea sent a letter to the board outlining her concerns and the county hired an attorney to investigate the jail.

Hall County Attorney Jack Zitterkopf says the settlement includes a non-admission clause, meaning Ruiz and Vann don’t admit any wrongdoing.

OMAHA, Neb. (AP) — Police have identified a man found shot to death in an Omaha backyard.

Officers say they were dispatched a little before 7:10 a.m. Wednesday to investigate a report about a person on the ground in a Benson-area yard. Police say they found 32-year-old Ronnie Devers unresponsive, and he was declared dead at the scene.

Police say Devers’ death is being investigated as a homicide, and investigators are trying to determine who is responsible.

No arrests have been reported.

DECATUR, Neb. (AP) — Company officials say they’ll be meeting Wednesday with residents who fled fumes that escaped from an anhydrous ammonia pipeline in northeast Nebraska.

Authorities have said a Tekamah man checking the leak was killed by the fumes Monday night.

Magellan Midstream Partners, of Tulsa, Oklahoma, said the meeting would start at 2 p.m. at City Hall in Decatur.

Magellan says it’s making progress on repairs. Company says it wants to isolate the failed portion of the 8-inch-diamer pipeline, which will allow local roads to reopen. A decision on letting people return to their homes will be made later Wednesday.

Magellan spokesman Thomas Byers says the incident is still under investigation and didn’t say whether Magellan had determined what caused the release of the fumes.
