FREMONT, Neb. (AP) — Authorities say a Nebraska woman whose 2-year-old son sprayed bleach on his baby sister’s face has been given probation.

The 26-year-old Tricha Speights was given 18 months of probation. Online court records say Speights pleaded no contest to two misdemeanor counts of negligent child abuse.

Police say Speights left her children alone in their apartment on May 5. When she got home, she found the boy had sprayed 3-month-old Gracelynn.

Records say the girl suffered first-degree burns on her face, and her vision might have been affected.

LINCOLN, Neb. (AP) — A threat to Nebraska’s ash trees has been found in northwest Missouri, less than 100 miles from Nebraska.

The Missouri Departments of Agriculture and Conservation and the U.S. Department of Agriculture say the emerald ash borer had been confirmed near Parkville, which sits on the northwest side of Kansas City, Mo.

Mark Harrell, of the Nebraska Forest Service, says there have been no confirmed sightings in Nebraska yet.

Ash trees account for 25 percent to 35 percent of trees in Nebraska. In Iowa, where sightings have been confirmed on the northeast side of the state, there are an estimated 88 million ash trees.

Larvae of the emerald ash borer beetle drill into ash trees, eat through vascular tissue and stop the flow of water.

LINCOLN, Neb. (AP) — Authorities say the eastbound Interstate 80 rest area east of Lincoln has reopened with more floor space and accessibility for wheelchairs.

The Nebraska Department of Roads says the men’s and women’s restrooms are bigger and a family restroom has been added. The department also says an exterior viewing platform that oversees the picnic area and a sculpture has been rebuilt and features a new stairway to the grounds.

The steel sculpture by Richard Field is titled “Memorial to the American Bandshell” and was installed in 1976.

The rest area sits about four miles east of the Greenwood interchange.

LINCOLN, Neb. (AP) — Record drought is causing Nebraska’s Platte River to dry up, and that’s threatening the water supply for the state’s second-largest city of Lincoln.

The river’s low level is putting the pinch on Lincoln’s 260,000 residents, because they get their water from wells sunk next to the Platte near Ashland.

Adding to the problem is the competition for water from Omaha, Nebraska’s largest city. Omaha has put in dozens of wells both upstream and downstream from Lincoln’s along the Platte over the past 10 years.

Jerry Obrist, chief engineer for the Lincoln Water Department, has been monitoring the area’s water levels and said the river’s flows are as low as those seen in the drought of 1955.

LINCOLN, Neb. (AP) — Squirrel hunting season is open in Nebraska, and officials say it provides a great opportunity to teach novices about hunting.

Mike Streeter with the Nebraska Game and Parks Commission says squirrel hunting can offer a good opportunity to teach someone to hunt.

And there are plenty of opportunities to hunt squirrels because the season runs through next Jan. 31.

Streeter says hunters should wear insect repellant and drink plenty of water when they go after squirrels. And hunters should be careful where they point their firearms, and they should make sure they know what might be behind or near their target.

The daily limit is seven squirrels.

OMAHA, Neb. (AP) — Alegent Health says it plans to rename its company after it acquires Creighton University’s hospital and clinics in Omaha.

Alegent said Sunday that on Sept. 1 it will become Alegent Creighton Health. And the company’s network of clinics around the city will be called Alegent Creighton Clinics.

But the names of Creighton University Medical Center and Alegent’s 10 hospitals will not change.

After the deal closes next month, Alegent will own all of Creighton’s hospital, which is one of two trauma centers in the state’s largest city.

Creighton’s hospital has been operated by the university’s partner, Tenet Healthcare. Tenet owned 74 percent of the hospital.

OMAHA, Neb. (AP) — A woman hit by a car while crossing a midtown Omaha street earlier this week has died of her injuries.

Omaha police say 41-year-old Mary Ryan died Saturday morning at Creighton University Medical Center.

Police say Ryan was crossing the street shortly before 3 a.m. Tuesday when she was hit by a car driven by 27-year-old man. Police say Ryan was not crossing at a marked crosswalk when she was hit, and that the driver of the car showed no signs of alcohol or drug impairment.

Ryan suffered multiple severe injuries, including a fractured skull, broken facial bones, arm and ribs. She also suffered bleeding in her brain. An autopsy has been ordered.

No arrests or charges have been made in the death, which is still under investigation.

LINCOLN, Neb. (AP) — A 28-year-old Lincoln man is behind bars after police say he held them at bay for nine hours.

Police were called to a Lincoln home Thursday afternoon for a man pointing a gun out of a window. Officer Katie Flood says that when police arrived, Damien Brown climbed out of a second-floor window and threatened officers with a knife and a screwdriver. Flood says he jumped onto a neighbor’s roof, where he stayed until surrendering around 1 a.m. Friday.

Brown was arrested on suspicion of making terroristic threats, using a weapon to commit a felony, trespassing and obstructing government operations. Police say after his arrest, a toy gun was found in his house.

Brown remained jailed Saturday and could not be reached for comment.
