OMAHA, Neb. (AP) — New Warren Buffett documentary will be shown in billionaire investor’s hometown of Omaha.

The Omaha premiere comes one week ahead of when the film will debut on HBO. Buffett and his family is expected to attend the Omaha event at the Holland Performing Arts Center Monday night. A similar event was held in New York last week.

The “Becoming Warren Buffett” documentary uses Buffett’s own words and interviews with friends and family members to explore what allowed him to become so successful at picking stocks and companies to buy.

The documentary discusses Buffett’s fascination with math and some of the experiences that helped shape his approach to investing.

Buffett also discusses his decision to give his fortune away to the Bill & Melinda Gates Foundation and four Buffett family foundations.

GRAND ISLAND, Neb. (AP) — Authorities are trying to determine what caused a minivan to veer off Interstate-80 in central Nebraska this weekend and kill two people.

A mother was travelling with two teenagers when the crash happened near the Wood River exit on Saturday afternoon. The 47-year-old woman and a teen girl died.

The Hall County Sheriff’s department says a 17-year-old boy was taken to a Grand Island hospital for treatment after the wreck.

The sheriff’s department says the 2005 Dodge Caravan swerved off the road and rolled several times in a ditch on the north side of the interstate.

Authorities didn’t immediately identify the people involved in the crash.

LINCOLN, Neb. (AP) — A former BNSF Railway employee has won more than $1 million in a wrongful termination lawsuit.

Daniel Monohon, of Ottumwa, Iowa, was fired from a Lincoln branch of Fort Worth, Texas-based BNSF in 2014 for what the railroad said was insubordination.

Monohon says he was fired after he questioned BNSF’s policy of requiring employees to wear seatbelts while driving a vehicle that can operate both on rail tracks and a conventional road. Monohon’s attorneys, Corey Stull and Jeanette Stull of Lincoln, argued that his firing was a violation of the whistleblower provisions of the Federal Railroad Safety Act.

A federal jury in Iowa agreed and awarded Monohon $1,031,000 in lost pay and other damages.

BNSF says it will ask the court to set aside the verdict and will appeal.

COUNCIL BLUFFS, Iowa (AP) — Police say a Council Bluffs mother has been charged after leaving her 12-year-old son on a roadside when he threw a tantrum.

The 33-year-old woman is set to be arraigned Feb. 20 on child endangerment and abandonment charges.

An officer found the boy walking along an Interstate 80 ramp at 6:30 a.m. in the morning last fall. The boy said his mother left him after he got out of the car over an argument about which shoes to wear to his school in Omaha, Nebraska.

Police say the boy had no phone, money for food or a key to the hotel room.

Police say the mother initially verified the boy’s account, asking officers, “What am I supposed to do? Be late for work?”
