HASTINGS, Neb. (AP) — A Florida man and woman have pleaded not guilty to charges of leading police on a high-speed chase through three counties in Nebraska.

31-year-old Keri Ansley and 34-year-old Christopher White, both of Milton, Florida, entered their pleas on Thursday. They face charges of possession of methamphetamine with intent to distribute and possession of a firearm by a prohibited person.

BEATRICE, Neb. (AP) — The swollen Big Blue River in Beatrice has fallen nearly 1.5 feet since cresting overnight at more than a dozen feet above flood stage.

National Weather Service records showed Friday that the river rose to 30.1 feet, less than 3 feet from the record of 33 feet.

Floodwaters had closed U.S. Highways 77 and 136 into and out of the southeast Nebraska city. On Thursday workers at the Gage County Museum removed items as water approached the main building and storage facility. The museum sits barely a block east of the river.

Rain reports from the Wednesday-Thursday overnight storms ranged from 5 to more than 10 inches in southeast Nebraska. Gov. Pete Ricketts declared a state of emergency.

OMAHA, Neb. (AP) — Nebraska officials say they’ve taken action to protect residents of two nursing homes run by an ailing Utah company.

The office of Nebraska Attorney General Doug Peterson says a judge in Brown County on Thursday placed Ainsworth Care Center into receivership with Klaasmeyer & Associates in Omaha. A judge in Burt County did the same with Logan Valley Manor in Lyons. Under receivership, Klaasmeyer & Associates will take over management and operation of both homes.

Peterson’s office sought the receiverships at the request of the Nebraska Department of Health and Human Services.

Officials say both homes are owned by Deseret Health Group, headquartered in Bountiful, Utah. Peterson’s office says Deseret Health had told Nebraska officials that it was ceasing operations at the nursing homes and been unable to pay staffers.

HARTFORD, Conn. (AP) — A powerful and potentially harmful chemical compound has been found in synthetic marijuana tested in several states that saw a huge spike in the number of people hospitalized because of the drug last month.

Recent tests have turned up a synthetic cannabinoid that mimics the effects of the main psychoactive ingredient in marijuana. Officials say it’s one of several cannabinoids that can cause severe health problems including seizures, elevated blood pressure and death.

Dr. Steven Marcus of the New Jersey Poison Information and Education System has been monitoring the recent hospitalizations spike. He tells The Associated Press that the same compound has been found recently in synthetic marijuana seized in New York, New Jersey, Pennsylvania and other states.
