The student was arrested Friday in a hallway of Papillion-La Vista High School, and the gun was found in his backpack.

Principal Jerry Kalina said in a message to parents that the student recorded the video in a student bathroom and posted it to Snapchat. Another student who saw the video reported it to school officials, and police were immediately called.

Kalina says there was no threat made by the student to other students or staff.

A district spokeswoman says possession of a gun on school grounds results in an automatic expulsion.

The high court on Friday rejected Shanna Golyar’s arguments that evidence presented at her trial was too thin to sustain a guilty verdict and that her trial lawyer was so deficient that she didn’t get a fair trial.

Golyar, of Persia, Iowa, was convicted and sentenced last year for murder and arson in the death of 37-year-old Cari Farver, who was last seen in Omaha in November 2012. Her body has never been found.

Prosecutors say Golyar posed as Farver online and by phone for years after her disappearance and also posed as other people confessing to having killed Farver. An officer testified that Farver had been dating Golyar’s ex-boyfriend for some weeks when she disappeared.

OMAHA, Neb. (AP) — A 14-year-old Omaha boy has taken a plea deal and will be sentenced in January for second-degree murder.

Douglas County District Court records say Tyon Wells pleaded no contest Thursday after prosecutors dropped three related counts. His sentencing is scheduled for Jan. 30 — a month after he turns 15.

Wells and a 15-year-old boy were arrested after two 17-year-old boys were shot Feb. 25 when Wells and his friend tried to buy marijuana. Prosecutors say 17-year-old Zachary Parker died of his wounds.

The judge cited Wells’ history of violence and familiarity with weapons in rejecting a motion to have Wells’ case moved to juvenile court.

Prosecutors didn’t charge the 15-year-old for the slaying.

Sioux City, Iowa, television station KCAU reports that the boil order was issued after testing of the city’s water revealed E. coli contamination.

Officials say tap water should be boiled for at least a minute before using it for drinking, brushing teeth, food preparation, washing dishes and making ice.

Residents will be informed when tests show no more contamination.

E. coli, a bacteria found in fecal matter, can be particularly dangerous to infants, young children, the elderly and those with compromised immune systems.

Douglas County District Court records say 23-year-old Alberto Castro-Sanabria was sentenced Wednesday. He’d pleaded guilty to vehicular homicide.

Omaha police investigators say Castro-Sanabria was drunk and driving 90 mph (145 kph) when his car rammed into a parked truck early in the morning of Nov. 25 last year. Police say his passenger and friend, 17-year-old Luis Castillo-Cabrera, was fatally injured.

Phelps County election records say Melton garnered less than 13 percent of the votes Tuesday, losing to first-term incumbent Doug Young. Melton had remained on the ballot after being taken into custody.
