OMAHA, Neb. (AP) — The Fort Calhoun nuclear plant in Nebraska has been taken temporarily offline due to a lockout of its main generator.

Omaha Public Power District says the plant automatically took its reactor and turbine offline Wednesday morning. Officials say the plant responded as designed.

Staffers are reviewing the cause of the generator lockout, but additional information has not been released. The Nuclear Regulatory Commission has been notified.

While the plant is offline, it remains at normal operating pressure and temperature.

Fort Calhoun, which sits about 20 miles north of Omaha, was shut down from April 2011 until December 2013.

LINCOLN, Neb. (AP) — The state of Nebraska has settled a lawsuit with one of six people wrongly convicted in a 1985 murder.

Lancaster County District Judge Robert Otte agreed Tuesday to a stipulated settlement that will pay $300,000 to Debra Shelden.

Shelden and five others — known as the Beatrice Six — were sent to prison in connection to the death of Helen Wilson. Shelden and two others spent five to six years in prison, while three others spent nearly 20 years locked up.

DNA testing exonerated the six, and a drifter who died in prison was linked to the death.

The Beatrix Six sued for wrongful conviction, and several have been awarded money. Shelden’s case was on hold pending a ruling from the Nebraska Supreme Court.

For the first time in several decades, a new treatment has been shown to limit the damage from a common type of stroke. Researchers in the Netherlands found that mechanically removing a clot in addition to using a clot-busting medicine lowered the risk that a stroke sufferer would end up severely disabled.

YORK, Neb. (AP) — York County prosecutors are appealing the five- to 10-year prison sentence of a York man for the 2013 crash death of an Aurora teacher.

Deputy York County Attorney Benjamin Dennis said 39-year-old Otis Newcomb’s sentence handed down by Judge James Stecker last month is “excessively lenient.”

Newcomb pleaded no contest in July as part of a plea deal that lowered a vehicular homicide charge and dismissed another charge.

Authorities say Newcomb was driving a van on Highway 34 near York in November 2013 when his vehicle collided with a pickup. A passenger in the pickup, 31-year-old Lauren Akerson, was killed. Others in the pickup were injured.

Prosecutors say Newcomb was drinking alcohol prior to the crash.

OMAHA, Neb. (AP) — Omaha police are investigating the robbery of a pizza restaurant and the assault of an employee.

Police say the robbery of a Little Caesars pizza restaurant in north Omaha happened around 9 p.m. Tuesday.

Police were alerted when an employee ran from the back door of the store to a nearby restaurant to call 911.

The employee told police that two men with masks came into the store. Three employees were inside at the time, and one was assaulted by the robbers.

That employee was taken to an Omaha hospital for treatment.

Police say the robbers got away with an undisclosed amount of money.

OMAHA, Neb. (AP) — An Omaha man who stabbed and wounded a police officer has been sentenced to prison.

A Douglas County judge on Tuesday sentenced 30-year-old Gary Jackson to two consecutive sentences of 10 to 25 years. Jackson previously pleaded guilty to felony assault on a police officer and being a felon in possession of a weapon.

Jackson will be eligible for parole in 22 ½ years.

Officer Sophia Jordan was injured in June while responding to a report that a man who had been banned from a convenience store was trying to get fuel.

Jackson attacked Jordan as she got out of her police car. The 14-year police veteran was stabbed in the shoulder and remains on limited duty.

DENVER (AP) — Colorado is poised to award more than $8 million to research marijuana to treat diseases, a step toward addressing complaints that little is known about pot’s medical potential.

The grants to be awarded by the state Board of Health are going to studies on whether marijuana helps treat epilepsy, brain tumors, Parkinson’s disease and post-traumatic stress disorder.

The awards are relatively small, but they represent a new frontier for marijuana research. That’s because the Colorado grants are outside of the usual federal channels for approving marijuana research.

Marijuana activists complain that the federal approval process has stymied research on marijuana’s potential as medicine.

Twenty-three states and Washington, D.C., allow marijuana use by people with various medical conditions. But under federal law, marijuana is considered a drug with no medical value.

GYPSUM, Colo. (AP) — A 14-year-old Colorado boy will spend 10 years behind bars after pleading guilty to killing his father and trying to conceal the slaying for six days by keeping the body at home and telling the man’s employer he was sick.

The boy entered the plea Tuesday and will be sentenced Thursday.

Investigators say the teen shot his 50-year-old father twice in the head in April, when the man was scheduled to meet with a sheriff’s deputy investigating a graffiti case involving the teen.

The father didn’t show up for the meeting or work. The son called his father’s boss for several days to say he was sick, but the employer became suspicious and alerted authorities.

The teen will serve seven years in youth prison before entering adult prison on his 21st birthday.
