OMAHA, Neb. (AP) — Authorities have released the name of an officer who was stabbed by a man at a convenience store in northeast Omaha.

Police say the officer was attacked Thursday afternoon while responding to a trespassing disturbance at the store.

The officer was identified Friday as 51-year-old Sophia Jordan, who has almost 15 years on the force.

OMAHA, Neb. (AP) — The Nebraska Supreme Court has again thrown out the conviction of Wyoming man accused of posing as a licensed car dealer and ordered a new trial in the case.

Thomas Merchant, of Cheyenne, Wyoming, has twice been convicted of being an unlicensed dealer after prosecutors said Merchant bought 19 vehicles from the Nebraska Auto Auction in June 2011. The business said the checks Merchant wrote for the vehicles bounced, and that Merchant included a fake dealer’s license number on paperwork that also indicated Merchant was a “wholesale” dealer.

His first conviction was reversed last year because of improperly admitted evidence. He was again tried and convicted and sentenced to 12 to 26 years in prison.

On Friday, the Nebraska high court vacated his second conviction, citing faulty jury instructions.

JOPLIN, Mo. (AP) — Residents of a southwest Missouri city devastated by a 2011 tornado are reaching out to the northeast Nebraska town of Pilger, which was torn apart by a tornado last week.

The campaign includes a Facebook page to offer encouragement and an account at Pinnacle Bank in Joplin, with all proceeds to go to the Pilger Community Development Fund.

The May 2011 tornado damaged hundreds of homes and businesses and killed 161 people in Joplin.

Joplin resident Doug Hunt, who was working Saturday in Pilger, says the campaign is part of his efforts to thank you to people who helped him and his city.

LINCOLN, Neb. (AP) — University of Nebraska officials say they will work with students who have been affected by recent severe weather.

Several areas of the state have sustained significant damage in tornadoes and thunderstorms this year.

Financial aid officials at all four University of Nebraska campuses will waive some required documents if they can’t be found and they may be able recalculate a family’s income to reflect storm losses.

Nebraska students who qualify for federal Pell grants might qualify for free tuition in the Collegebound Nebraska program if they experienced significant storm losses.

Interim NU President James Linder says financial aid officers will work to minimize how much the severe weather affects students’ ability to attend college.

OMAHA, Neb. (AP) — Lawyers for the Omaha Public Power District say employee severance deals worth upward of $700,000 are not public records.

The district’s attorneys argued in court on Wednesday that even if the deals with seven former employees were public records, they couldn’t be disclosed because they contain personal information beyond salary data.

The records dispute began with a public records request submitted to the publicly owned utility last fall by Mark Salerno, president of the International Brotherhood of Electrical Workers Local 1483. He sought details on the payouts. The district declined to say who was paid and why, so Salerno appealed to the courts.

The judge didn’t make a ruling Wednesday.

ELK CREEK, Neb. (AP) — A Canadian firm hoping to build a mine to collect a valuable and rare heat-resistant element from beneath southeast Nebraska says the first samples collected this year are encouraging.

NioCorp Developments said Thursday the initial analysis of 230 samples reinforces the company’s positive view of the niobium deposit near Elk Creek.

The drilling that Vancouver, Canada, based NioCorp is doing this summer is designed to gather more data on the niobium deposit, so the company can determine whether raising more than $300 million for a mine is feasible.

The U.S. currently imports nearly all the niobium that’s used in this country to harden steel and make it more heat-resistant for industrial uses.

NioCorp previously estimated that more than 100 million tons of niobium rests several hundred feet below the ground.

LINCOLN, Neb. (AP) — Authorities have released the name of a motorcyclist who plunged to his death from an overpass in Lincoln.

The accident occurred about 5 p.m. Tuesday when something caused the motorcyclist to hit a concrete barrier on Rosa Parks Way and fall from his bike to a parking lot below.

He was identified as 19-year-old Mark Wenzl, of Seward.

Investigators had thought another vehicle may have been involved but have ruled that out as a possible cause of the crash.
