LINCOLN, Neb. (AP) — A semitrailer fire on Interstate 80 at Lincoln has backed up westbound traffic on a busy holiday weekend.

The truck caught fire around 10 a.m. Saturday just west of Lincoln, stalling traffic for miles.

Traffic was diverted north to U.S. Highway 34 at exit 395 and south to U.S. Highway 6 at exit 397 until around noon.

The Nebraska State Patrol, Lancaster County Sheriff’s Office and Lincoln Fire and Rescue were called to the scene. No injuries were reported.

SOUTH SIOUX CITY, Neb. (AP) — A former employee at a South Sioux City school has been sentenced to 90 days in jail for sending nude photographs to a 15-year-old student.

28-year-old Cecilia Hermosillo worked as a paraprofessional at Gateway to Learning and resigned last September. Gateway to Learning is an alternative high school in South Sioux City.

Police began investigating last year when a school resource officer reported a post on Facebook referencing nude photographs sent by a school employee to a student. Police say they were able to obtain the pictures from the 15-year-old boy.

Hermosillo turned herself in after an arrest warrant charging her with enticement by electronic communication device was filed. She pleaded no contest to attempted child abuse in April.

OMAHA, Neb. (AP) — The Douglas County Sheriff’s Office says an entrance screening officer violated some procedures when his gun accidentally fired inside the county courthouse.

The officer was checking the slide on the gun when it fired. The gun went off at a closed exit, and no one was hurt. The bullet pierced an X-ray machine and hit a concrete wall near the machine.

Douglas County Attorney Don Kleine said Friday that had it not been for the concrete wall, the bullet likely would have gone through a conference room and into his office. Kleine was not in the office at the time the gun went off.

The department says an internal investigation showed some procedures were violated and that corrective action will be taken.

OMAHA, Neb. (AP) — Eastern Nebraska health officials are warning that smoke from July Fourth fireworks could create air quality issues and trigger reactions in those sensitive to pollutants.

The Douglas County Health Department says the concern is greatest this weekend through Wednesday, the day after Independence Day.

Fireworks smoke may cause breathing to be difficult for individuals with asthma or other heart or lung diseases, the elderly, very young children, and pregnant women.

Health director Dr. Adi Pour says those people can minimize the risk by avoiding strenuous outdoor activity and limiting time spent outdoors.”
