MANHATTAN, Kan. (AP) — A Manhattan, Kansas, businessman who once was a backup quarterback at Kansas State faces November sentencing after admitting in court that he had improper sexual contact with a former high school student.

Zachary Burton, 38, pleaded guilty Monday in Riley County to one count of unlawful sexual relations.

Authorities say the female student went to Riley County High School, where Burton was an assistant boys’ basketball coach and substitute teacher.

Burton owns a business called Fieldhouse Development Inc.

Burton’s sentencing is scheduled for Nov. 15.

PECULIAR, Mo. (AP) — Authorities are investigating a fatal fire in western Missouri.

The Cass County Sheriff’s Office said in a news release that a neighbor reported the fire Monday afternoon in rural Peculiar. The single-story home was engulfed in smoke and flames when crews arrived and found the victim inside.

The name of the victim wasn’t immediately released. The sheriff’s office said no one else was hurt and noted that the victim was the only person in the home at the time of the fire. The cause of the blaze is under investigation.

KANSAS CITY, Mo. (AP) — A Johnson County horticulturist says the number of people dealing with bites from the oak leaf itch mite has picked up this year. Dennis Patton, a horticulturist for the Johnson County Kansas State University Research and Extension Office, tells The Kansas City Star that the mites have been back in full force and that the number of calls from people who’ve been bitten has picked up.

Itch mites are associated with a wasp-like insect that forms galls on oak trees. When the insect stings the leaves, a gall forms around the insect’s larvae. The mites then feed on the larvae and exit the gall in the fall.

There has been a high number of galls forming on oak trees this year. Patton says the mites get on humans after being windblown.

KANSAS CITY, Mo. (AP) — A group that presses single women, minorities and millennials to register to vote is apologizing for sending 95,000 mailings listing the wrong Missouri registration deadline.

Casting itself as nonpartisan, the Washington-based Voter Participation Center says the registration forms this month listed Missouri’s registration cutoff for the Nov. 8 election as Oct. 17.

It’s actually Oct. 12, and the center says it has sent out new postcards reflecting that.

The center calls the matter “inadvertent,” says it regrets the error and has apologized in writing to Missouri Secretary of State Jason Kander.

The county clerk in central Missouri’s Boone County, Wendy Noren, has told media outlets the questioned mailings could lead some voters who already are registered to believe they’re not, discouraging them from going to the polls in November.

CEDAR RAPIDS, Iowa (AP) — Officials in Cedar Rapids say an elaborate system of temporary floodwalls is successfully protecting thousands of homes and businesses from floodwaters.

Iowa’s second-largest city said its hastily-erected 9.8-mile system of Hesco barriers and earthen berms was largely holding back the Cedar River, which was cresting Tuesday at its second-highest level in history.

The barriers were invented by British entrepreneur James Heselden, a former coal miner who used them to stop erosion on his property. They were then used by the United Kingdom’s military to replace sandbags that protected soldiers from blasts in Bosnia. The U.S. military later used the barriers extensively in Iraq and Afghanistan.

As of Tuesday morning, city officials said the barriers had prevented most damage but that some buildings and homes near the river will likely have water in their basements.

City workers and contractors worked through the night to pump out water that seeped through the barriers and that came up through the sewer system.

Firefighters and police also rescued a woman who was swept away Monday afternoon by the river.

NEWTON, Iowa (AP) — Authorities say a detective helping with an arrest in Newton accidentally shot himself.

The Mid-Iowa Narcotics Enforcement Task Force said in a news release that officers approached 25-year-old Chad Coady in a restaurant parking lot about 9:30 p.m. Monday. The release says Coady drove toward the officers’ vehicles, causing two crashes.

According to the release, the handgun of one of the officers then went off as he was putting it back into its holster. The bullet struck the officer’s lower right leg. The officer was later reported in good condition at a Des Moines-area hospital. The officer’s name hasn’t been released.

Officers arrested Coady on a warrant alleging parole violation. Court records don’t list the name of an attorney who could be contacted to comment for Coady.

OMAHA, Neb. (AP) — Nebraska Department of Health and Human Services officials have revealed a billing problem that could cost the state up to $32 million.

The issue stems from changes made two years ago in how providers are paid for serving residents with developmental disabilities.

The changes put Nebraska at odds with federal Medicaid regulations, which means the state could have to repay millions of dollars. The exact total isn’t known yet.

Department spokeswoman Leah Bucco-White says it’s working closely with developmental disabilities service providers and the federal Centers for Medicare and Medicaid Services to begin a claims review of services provided within the Home and Community-Based Services waiver program, which is paid with both federal and state funds.

Bucco-White says the review is expected to take a couple of months.

OMAHA, Neb. (AP) — University of Nebraska at Omaha Chancellor John Christensen will step down at the end of this school year.

Christensen said Monday that he plans to retire next spring after 10 years as chancellor. But he will remain in the job until his successor is chosen.

Christensen has spent nearly 40 years at UNO, and he is the first UNO alumnus to have led the university.

He oversaw dropping the sports of football and wrestling when UNO moved up to Division I. UNO also built its own arena for its hockey and basketball teams.

And during Christensen’s tenure, UNO improved its already strong engineering and business programs and earned recognition for its doctoral research from the Carnegie Foundation.

WICHITA, Kan. (AP) — A federal judge has ordered Kansas Secretary of State Kris Kobach to show why he shouldn’t be held in contempt for failing to comply with an injunction requiring him to put on voter rolls people who registered at motor vehicle offices without providing citizenship documents.

U.S. District Judge Julie Robinson on Monday ordered Kobach to appear in her courtroom Friday and to file a written response by Thursday.

Kobach says the state “is in full compliance with the district court’s order.”

The American Civil Liberties Union contends Kobach has not registered these voters in the official poll books as Robinson ordered in May. The ACLU argues Kobach also issued a misleading voter notice.

These voters aren’t given a regular ballot and must use a provisional one, which raises secrecy concerns.

WASHINGTON (AP) — The U.S. Army says it has fired the commander of Fort Riley and is continuing an investigation opened last week at the Kansas base. No details have been provided.

Army spokesman Col. Patrick R. Seiber says that Maj. Gen. Wayne Grigsby was relieved of command of the 1st Infantry Division due to loss of confidence in his ability to lead. Grigsby was initially suspended on Friday. Army officials have declined to disclose the nature of the investigation.

Seiber says a replacement will be named in the coming days.

About 17,000 troops are stationed at Fort Riley. Grigsby assumed command of the base in August 2015, after 31 years of military service that included a stint as commander of the Combined Joint Task Force in East Africa.
