(AP) — Coroner’s officials say the death of Julia Roberts’ half-sister in February was a suicide.

An autopsy and toxicology tests led to the determination that Nancy Motes drowned in a bathtub after taking several drugs that have not yet been publicly identified.

Los Angeles coroner’s spokesman Craig Harvey says the drugs will be listed in a full autopsy report that could be released as early as next week.

Harvey says 37-year-old Motes left behind a suicide note and that it will be turned over to her family.

Motes was the younger sister of actress Julia Roberts and actor Eric Roberts.

A receptionist for Julia Roberts’ publicist, Marcy Engelman, said Engelman was out of the country and unavailable to comment and that no one else was available.

(AP) — Two major electric transmission lines damaged in last weekend’s storms have been repaired, but more work remains to restore power to everyone in eastern Nebraska.

The Nebraska Public Power District said Wednesday that it had restored power to transmission lines between Sutton and Hastings and between Davey and Wahoo.

NPPD says it still has two other transmission lines to repair. The repairs to all four lines will cost roughly $17 million.

Those major transmission lines generally deliver power to smaller utilities that serve individual homes and businesses across the state.

In heavily damages areas, those smaller utilities are still working to repair all the damage from Sunday’s tornadoes.

(AP) — A murder trial has been delayed for a 24-year-old Guide Rock man accused of helping his mother kill the mother of her boyfriend.

The attorney for Andrew Casterline had asked the judge for the delay. Last week, the judge complied with the request, setting a new trial start date of Sept. 8. The original date was May 27.

Casterline is accused of stabbing 68-year-old Virginia Barone on Oct. 4 at her home in Guide Rock. His mother, 41-year-old Shelley Casterline, in March pleaded guilty to a reduced murder charge. She’s scheduled to be sentenced on June 10.

Investigators have said Shelley Casterline acknowledged she’d killed Barone after the older woman made comments that enraged her.

(AP) — Nebraska officials estimate that last weekend’s tornadoes caused at least $20 million damage across the state.

The Nebraska Emergency Management Agency said Tuesday that part of the reason why the damage estimate is so high is that Sunday’s storms caused extensive damage to power lines.

The storm cleanup effort continued Tuesday as resident and volunteers worked to pick up fallen tree limbs and building debris.

The eastern Nebraska towns of Beaver Crossing, Cordova and Sutton sustained some of the most extensive damage.

But Sunday’s storms damaged homes, businesses and farms across a large area between Hastings and Omaha.

NEMA officials say it appears that the storms spawned at least a dozen tornadoes Sunday. But National Weather Service officials are still examining the damage to classify the storms.

(AP) — Iowa authorities have confirmed that a body found in the Missouri River is that of a missing Nebraska man.

Iowa officials and police in Fremont, have identified the man as 56-year-old Thomas Hill, of Fremont.

The body was found Saturday off Fremont County, Iowa, south of Omaha. Hill was reported missing on April 18. His car was found parked near the Bob Kerrey Pedestrian Bridge in Omaha.

An Iowa autopsy report says Hill drowned.

(AP) — Two 16-year-olds are facing assault charges after an altercation that left another teen critically hurt.

Family members say Aquilee Muse was taken off of life support Tuesday after doctors said he was brain dead.

Police say Muse was walking with several other teenagers when they were confronted Friday afternoon by the two 16-year-olds in Omaha.

Police say Muse sustained a head injury in the attack and was hospitalized in critical condition. Doctors said Saturday that Muse was not expected to survive.

(AP) — Authorities in Lincoln have arrested an 18-year-old high school student after homemade explosives were found in his car at school.

Lincoln police say George Carl Chen was taken into custody Monday. He faces felony charges of unlawful possession of explosive materials and possession of a destructive device. Court records do not list an attorney.

Police say they discovered on May 7 more than 160 rifle rounds and 26 homemade firecrackers in Chen’s car at Lincoln East High School. Another 50 rounds were found in his backpack.

Chen told investigators he uses the rounds for target practice. He said the fireworks were from Fourth of July celebrations. Officer Katie Flood says there’s no evidence that Chen meant to harm anyone at the school.

(AP) — Some University of Nebraska-Lincoln students have been learning valuable lessons in mentoring troubled youths.

Anne Hobbs teaches the two-semester juvenile mentoring class. She said each student is matched with one youth at the Geneva or Kearney youth treatment and rehabilitation centers. The students see their mentees once every other week during the fall and spring semesters. The goal is to provide positive role models to the juveniles and train the college students to work with troubled youths.

Students spend months with their mentees and expect the relationships they’ve built to blossom once the youths are released. But, says Hobbs, the younger people often sever those ties.

Hobbs says “the addiction is so strong with these kids.”

(AP) — One person has been injured in an Omaha house fire.

The blaze was reported around 4:30 a.m. Tuesday at a home about a mile and a half west of downtown. The injured person was taken in serious condition to Nebraska Medical Center.

Firefighters think the fire began in the rear of the house. The fire cause is being investigated.

(AP) — The new headquarters building for the Ponca Tribe of Nebraska will provide space for an array of services and a community center the tribe will share with the Niobrara community in northeast Nebraska.

The building is expected to be ready for occupancy early next year and contain around 9,000 square feet, which is more than double the space in the former grain and feed building the tribe operates out of now.

Other tribal sites in Lincoln, Norfolk and Omaha and in Sioux City, Iowa, also offer services for tribal members.

The 3,600-member Ponca Tribe of Nebraska is the name used to describe the Northern Ponca Tribe since the tribe was officially restored to sovereign nation status in 1990. It doesn’t have a reservation.
