LINCOLN, Neb. (AP) — Union College in Lincoln has hired an outside organization to investigate the Jan. 14 accident that seriously injured a 23-year-old gymnast from California.

Heather Boulais, of Laguna Niguel, California, fell 23 feet while installing aerial silks in the college gym before one of the acrobatics team’s practices. Her parents, Terry and Cheryl Boulais, say doctors are trying to regulate the pressure on her brain from the trauma. Her skull was fractured.

Union College President Vinita Sauder says the outside organization will gather facts, determine what happened and make recommendations. Sauder didn’t there was no timetable for the investigation.

Union College is a four-year college that’s owned and operated by the Seventh-day Adventist Church.

OMAHA, Neb. (AP) — The Omaha Public Power District board has delayed action on naming a new CEO as the Omaha World-Herald considers challenging the legality of the secret process.

At a special meeting Thursday morning the board acknowledged that its choice to replace retiring CEO Gary Gates is Tim Burke, who is district vice president of customer service and public affairs. But board members tabled the resolution to promote Burke until the next regular board meeting, citing public concerns about the process.

District board chairwoman Anne McGuire said Wednesday that board members interviewed four finalists in secret last week, but the district has refused to release their names. World-Herald officials say that under the state’s open records law, the district must release information about the final four candidates.

WATERLOO, Neb. (AP) — A Platte River ice jam near Omaha has broken up on its own, so officials have canceled plans to attack it with dynamite.

The 1½-mile-long jam had backed up river water in western Douglas County, just west of Omaha, and parts of Saunders County, threatening homes, well fields and a National Guard camp.

But the jam broke up on its own by 9:45 a.m. Thursday.

LINCOLN, Neb. (AP) — Nebraska authorities say they caught a 31-year-old Minnesota man with nearly 30,000 marijuana pills in a U-Haul trailer attached to his car.

Lancaster County Sheriff Terry Wagner says police noticed on Tuesday that Ryan Scott Cooper, of Plymouth, Minnesota, didn’t have a license plate on the front of his car when he was getting gas at a station in Lincoln. He says a police dog then signaled the smell of drugs coming from the attached trailer.

Officials say they searched the trailer and found 29,400 capsules filled with cannabis oil and 322 Adderall pills, along with other drugs and equipment to make the oil.

Cooper was arrested on suspicion of breaking four drug laws, including two felonies. An attorney for Cooper couldn’t be located.

WATERLOO, Neb. (AP) — Officials say they plan to use dynamite to blast an ice jam on the Platte River if it doesn’t start moving downstream.

John Winkler, general manager of the Papio-Missouri River Natural Resources District, says explosives will be used if the mile-long ice jam doesn’t move by Thursday morning. The ice jam caused flooding Tuesday in western Douglas County, just west of Omaha, and parts of Saunders County.

A helicopter would be used to drop the dynamite onto the ice jam. He says he’ll join emergency management officials to assess the situation and decide whether blasting is necessary.

Winkler says no evacuations are planned at this time, and levees along the river are currently holding.

DENVER (AP) — Tourists who fly to Colorado to try legal pot can forget about buying souvenir boxer shorts, socks or sandals with a marijuana leaf on them at the Denver airport.

The airport has banned pot-themed souvenirs, fearing the kitsch could taint the state’s image.

Marijuana possession and any pot-related advertising were already forbidden. Airport executives extended the ban this month after a retailer sought a kiosk to sell the boxer shorts and similar items that played off Colorado’s place as the first state to allow recreational marijuana sales.

Ann Jordan is owner of High-ly Legal Colorado, which makes the souvenirs.

She asked why airport officials were “so riled up about the picture of a plant,” and she noted that the airport has an exhibit celebrating another adult product, Colorado craft beer.

DEWITT, Neb. (AP) — A 26-year-old DeWitt resident convicted of shooting another man has been given up to 10 years in prison.

Zachary Grummert was sentenced on Monday. Grummert was given six to eight years for attempted assault and 10 to 12 months each for terroristic threats and possessing a short shotgun. The sentences are to be served consecutively.

He was arrested last May after the shooting of a Beatrice man, Joshua Voorhees. Witnesses say Voorhees was shot after stepping between Grummert and another man who were arguing at a party in DeWitt. Grummert told police that Voorhees and another man were starting fights at the party.
