OMAHA, Neb. (AP) — A former Omaha teacher has been sentenced to 40 years in prison for having a sexual relationship with a former student of his.

Online court records say 36-year-old Brian Robeson was sentenced Tuesday. He’d made a deal with prosecutors and pleaded guilty to sexual assault of a minor. Prosecutors had lowered the charge and dropped another in exchange for Robeson’s plea.

Robeson was a math teacher at Davis Middle School. Authorities say the relationship began when the girl was 13.

OMAHA, Neb. (AP) — An expert has testified that DNA recovered from the scene of a home break-in could not rule out a former doctor on trial in the deaths of four people with ties to an Omaha medical school.

A judge sustained a defense objection Tuesday to the expert’s testimony that the DNA likely came from Anthony Garcia or a male related to him.

The DNA was collected from the Omaha home of Dr. Chhanda Bewtra, where a break-in occurred in May 2013 around the same time her Creighton University School of Medicine colleague, Dr. Roger Brumback, and his wife, Mary, were killed.

Prosecutors say Garcia also killed the 11-year-old son of Creighton’s Dr. William Hunter, and the family’s housekeeper in 2008. They say Garcia was angry at being fired by the doctors in 2001.

OMAHA, Neb. (AP) — Warren Buffett has the kind of money problem most people would envy: a growing mountain of cash.

Buffett’s Berkshire Hathaway is holding more cash than ever with nearly $73 billion on hand. And the total grows every day he doesn’t make a deal.

Buffett says he’s always hunting for sizeable acquisitions for Berkshire, but he’s mostly sitting on the cash this year.

Investor Andy Kilpatrick, who wrote “Of Permanent Value: The Story of Warren Buffett,” says he thinks Buffett is looking for a great company selling at the right price.

Berkshire earns little on its cash, but Buffett isn’t likely to feel much pressure from shareholders.

After all, Buffett still controls nearly one-third of the voting stock, and Berkshire shareholders have rejected the idea of a dividend before.

CHERRYVALE, Kan. (AP) — Police in the tiny town of Cherryvale, Kansas, looking to track down the owner of an abandoned gram of crystal meth have taken their case to social media.

A bag with methamphetamine was found Sept. 29 at a convenience store in the southeast Kansas community of about 2,300 people. So Cherryvale police politely posted about it on the department’s Facebook page.

The post reads: “We are very concerned and would like to find the owner so please notify us and describe the packaging and we will see what we can do for you.”

It’s been shared nearly 1,700 times. But Police Chief Perry Lambert says no one has come forward as the owner of the illegal stimulant — though he says he’s hopeful.

OMAHA, Neb. (AP) — The family of a man shot by an Omaha police officer last year has filed a wrongful death lawsuit against the city and the former officer who fired the fatal shot.

The lawsuit was filed Monday in Douglas County District Court and seeks $2 million for the Feb. 23, 2015, shooting death of 39-year-old Danny Elrod. Police confronted Elrod, who was suspected of robbing a nearby store, and say Officer Alvin Lugod shot him after Elrod refused to comply with commands and turned and reached for a fence behind him. An investigation determined Elrod was unarmed when he was shot, but cleared Lugod of wrongdoing in the shooting.

Lugod resigned following a departmental investigation.

The lawsuit offers to settle the case for $500,000.
