Skin exposed to the toxin can develop rashes and blisters, and drinking tainted water could cause headaches, nausea and muscle pain.

Woodbury County court records say 43-year-old Larry Johnson II pleaded not guilty Friday to assault on an officer. His trial is set to begin Oct. 2.

The Nebraska State Patrol says the incident occurred July 6 when a Nebraska trooper tried to stop a pickup truck being pursued by South Sioux City police. Officials say the truck rammed the trooper’s car, which had maneuvered in front of it, from behind before crossing into Iowa.

The trooper and a Dakota County sheriff’s cruiser following the truck onto Interstate 29 before it went out of control and became stuck in a median. Officials say the truck then rammed both the trooper’s car and the sheriff’s vehicle before Johnson was arrested.

The two were working with a generator in the semitrailer Monday morning outside Westfall Elementary School in Malcolm when the explosion occurred. Malcolm Fire Chief Jim Densberger says both the men were taken to a Lincoln hospital. Their names haven’t been released.

Authorities say the two are subcontractors working on a school expansion project. The school was not damaged.

No other injuries were reported. School is not in session.

Omaha-based animal health technology startup Corbyt has proposed the 90,000 square-foot private facility named the Nebraska Canine Commons, the Omaha World-Herald reported. The indoor dog park would be run by the new nonprofit Nebraska Canine Commons.

The group’s plans include a play area with dog agility equipment, a micro-clinic and classrooms for dog training and specialized turf that drains liquid waste and manages pet odor. Customers would pay a membership fee of $79 per month and an extra $15 per month for each additional dog.

The idea for the indoor facility came from a vizsla dog breed owner group.

“As we went into the winter months we realized there’s nothing really we can do (for vizslas) and there would be a great demand for an indoor facility for dogs,” said Sarah Dring, who helped run the dog breed group and now serves as co-founder of Nebraska Canine Commons.

Dring and Corbyt CEO Jon Cady collaborated with a design team to envision the indoor dog park, and now they’re working to fund the project.

The nonprofit hasn’t yet chosen a location.

The indoor dog facility could begin construction next year and open in 2020 if the group can complete fundraising.

A battalion chief caught a whiff of smoke at the station a little after 10 a.m. Sunday and found the station kitchen ablaze. He called for help because most of the firefighters assigned there were out on a call.

Fire crews from a station less than 5 miles (8 kilometers) away responded. It took them about 15 minutes to put out the fire in the kitchen and living areas. No injuries were reported.

The fire cause is being investigated. Most of the station’s firefighters and equipment were moved temporarily to another station.

Fire crews were dispatched around 7:50 p.m. Wednesday to the Shadow Ridge complex in La Vista. Authorities say the blaze spread to two adjoining garages but didn’t reach the residents’ buildings.

The man was working on a truck in his garage when the fire started. He suffered burns on his hands in trying to extinguish the flames. His name wasn’t released.

The crash occurred around 5:40 p.m. Thursday, when the southbound motorcycle went out of control, crossed a grass median and an on-ramp and overturned on an embankment.

Police say the motorcyclist was taken to Nebraska Medical Center, where he died.

He’s been identified as 45-year-old Bill Pyle, who lived in Omaha.
