WEST POINT, Neb. (AP) — Federal officials are opening an investigation into an explosion and fire at a northeast Nebraska petroleum distribution center that left seven people injured.

The U.S. Department of Labor’s Occupational Safety and Health Administration says officials at its Omaha office will look into the Wednesday afternoon explosion at Sapp Bros. Petroleum in West Point. The agency says it will investigate whether there were safety violations at the facility and if it contributed to the incident.

OSHA says it hasn’t inspected the Sapp Bros. facility in West Point in the past five years, though it has issued citations for other company locations.

Two of the injured people were taken to the burn unit at an Omaha hospital.

OMAHA, Neb. (AP) — The city of Omaha has fined a Kansas-based company $100,000 after complaints about delayed yard waste pickup.

City officials met with representatives from Deffenbaugh Industries Wednesday to address the complaints filed in May and June. The company and the city say the pickup problems stem from a shortage of workers with commercial driver’s licenses.

The waste and recycling firm has brought in 10 drivers from other cities, and plans to hire an additional 23 drivers.

Mayor Jean Stothert’s office says Deffenbaugh also has agreed to work with schools and job training programs to recruit new workers.

Deffenbaugh began picking up yard waste along with trash this week. It plans to keep taking yard waste to the county landfill through October.

NEW YORK (AP) — Google is apologizing after reports surfaced that an automatic image-recognition feature in its Photos application was identifying images of some black people as “gorillas.”

A New York man posted a picture of himself and a female friend on Twitter earlier this week, showing that the Google image software had tagged both of them as “gorillas,” which is sometimes used as a racial slur.

Google says it’s “appalled and genuinely sorry” for what happened with the image-recognition feature. It says it’s taking immediate action to stop those kinds of results from appearing again.

TECUMSEH, Neb. (AP) — A southeast Nebraska woman accused of having sex with a 15-year-old student has been sentenced to four to five years in prison.

Carrie Miller of Tecumseh pleaded guilty to charges as part of plea deals in Johnson and Nemaha counties. She was sentenced Wednesday in Nemaha County. The 25-year-old was also ordered to register as a sex offender for 15 years.

According to court documents, Miller taught at Johnson County Central High School and had a relationship with the teenager for about year. Under Nebraska law, people 19 and older cannot have sexual contact with people younger than 16.

GRAND ISLAND, Neb. (AP) — State officials have rejected Hall County’s effort to raise its daily fee for housing state prisoners.

County corrections director Fred Ruiz told the county Board of Supervisors on Tuesday that he’d sought $93 a day, an increase of $5 from the current $88 a day. And he sought a guarantee of 90 state inmates a day.

The state rejected his bid and countered with an offer of $88 a day for 82 state inmates.

The county board voted Tuesday to offer the state a rate of $88 per day for 82 beds and offer to provide space for 14 more inmates for $75 a day each.

COLUMBUS, Neb. (AP) — A September trial has been scheduled for a 22-year-old Columbus man accused of seriously injuring the 4-month-old daughter of his live-in girlfriend.

Francisco Villatoro has pleaded not guilty. He’s charged with intentional child abuse resulting in injury. His trial is set to begin Sept. 28 in Platte County District Court.

Villatoro was arrested after calling 911 on May 23 to report that the baby was choking. The infant was taken to Columbus Community Hospital and then transferred to Omaha Children’s Hospital & Medical Center in Omaha.

Doctors say the infant suffered a head injury. Police say it happened as Villatoro was caring for the child while his girlfriend was at work.

LINCOLN, Neb. (AP) — A trailer park that’s been home to several down-on-their-luck Lincoln residents has been sold and will be razed to make way for a parking lot for college students.

The Arrow Mobile Home Court was sold earlier this month to a limited liability company run by an Indiana-based business that specializes in building and managing student housing complexes. Trinitas Ventures plans to turn the trailer park into an offsite parking lot for residents of the seven-story student housing complex that it’s building at a different site.

The property and two adjacent lots were purchased June 17 for nearly $800,000 from trailer park owner Gary Nicholsen.

The trailers and other buildings will be cleared beginning Aug. 1.

OMAHA, Neb. (AP) — An academic medical center in Nebraska has been designated as a national facility for Ebola training.

The University of Nebraska Medical Center and its primary clinical partner, Nebraska Medicine, will receive a little over $5 million from the U.S. Department of Health and Human Services for the designation.

The award is part of $12 million in federal dollars being shared with Emory University in Atlanta and Bellevue Hospital Center in New York City. The three academic institutions will work with federal officials to train health care providers and facilities on strategies to manage Ebola and other emerging infectious diseases.

The Nebraska center has played a key role in the U.S. response to the Ebola outbreak. It’s offered treatment to infected patients and provided training to health care workers.
