DODGEVILLE, Wis. (WMTV) – A criminal complaint reveals the man accused of killing a Dodgeville woman, whose body was found in Nebraska, admitted to stabbing her and taking her SUV.

Dorinda Segebrecht was found dead in the backseat of a vehicle in Lincoln, Nebraska, early Wednesday morning.

Gavin Thompson, a 23-year-old Dodgeville man, was arrested after a vehicle pursuit, crash and massive manhunt in Lincoln, Nebraska.

A criminal complaint stated Dorinda Segebrecht did not show up to a planned family outing and stopped responding to text messages after 11:25 a.m. on Tuesday. Her family then called in a welfare check to police.

Family members determined her car was not at home, but her purse, keys and a damaged pair of glasses were still there. Law enforcement reported finding blood stains in the front of the home, according to the complaint.

The complaint recounted a person of interest was seen wearing a blue shirt, camouflage jacket and yellow shoes walking in the southeast area of Dodgeville throughout the day. He was spotted on a camera in the 400 block of E. Division St at 2:23 p.m., and Segebrecht’s car was seen on the camera driving away about 10 minutes.

After he was arrested in Nebraska, Thompson allegedly admitted he needed money and a car because he had recently lost his job. He said he went inside the victim’s home, which was unlocked, without knocking because it appeared to be a calm place. He said “emotions collided” and a death happened, the complaint stated.

He allegedly admitted to stabbing the victim, and said he did not intend to kill her. He just wanted the car, according to the complaint.

Thompson also allegedly admitted to trying to clean up the home while wearing gloves and stealing a few hundred dollars, the complaint states. He took the car keys and put Segebrecht’s body into her Hyundai Kona SUV because he thought taking her body with him was “the right thing to do,” the complaint alleges.

Thompson faces charges in Iowa County that include first-degree intentional homicide, burglary while armed with a dangerous weapon, hiding a corpse and operating a motor vehicle without owner’s consent.

He is facing charges in Nebraska of operating a motor vehicle to avoid arrest, hiding a corpse and theft by unlawful taking of $5,000 or more.

At his arraignment in Lancaster County, Nebraska, a judge set Thompson’s bond at 10% of $5,000,000.

He is currently being held in the Lancaster County Jail. Thompson will be awaiting extradition back to Wisconsin, which Dodgeville Police Chief Brandon Wilhelm said he expects to take up to a week. Wilhelm said he personally will head to Nebraska to take Thompson in.

Segebrecht’s vehicle was spotted around 6:45 p.m. Tuesday in Peru, Illinois.

Throughout the night, Wilhelm said authorities followed up on leads that led them from St. Charles, Missouri, to the Lincoln, Nebraska, area.

Nebraska State Patrol eventually spotted the vehicle at 1:50 a.m. Wednesday and tried to pull it over. Thompson allegedly took off, eventually lost control and crashed. He got out of the car and ran off.

It was at that point that law enforcement found Segebrecht’s body in the back of the vehicle.

Wilhelm said a manhunt for Thompson was ongoing until around 6 a.m. Wednesday, and police arrested him.

Wilhelm asked residents in the City of Dodgeville and nearby rural areas to take note of anything suspicious they may have noticed from 12:30 p.m. to 3:30 p.m. on July 15, including sightings they may have had of Thompson.

Wilhelm said home surveillance video, or anyone who saw the suspect or vehicle, could help law enforcement in the investigation. Witnesses can send any information to policetip@dodgevillewi.gov.

Iowa County Sheriff Michael Peterson said the Segebrecht family wanted to release a statement to the public.

“That they would like to thank all of the law enforcement agencies in Wisconsin, Nebraska, Missouri, Iowa, and Illinois that has assisted us with her case,” Peterson said. “The outpouring of community support has just been overwhelming. We appreciate the continued respect of our privacy at this time.”

Peterson also thanked the Thompson family for their cooperation and respect during this investigation, saying law enforcement recognize the emotional toll it has taken on them, as well.

Dodgeville Mayor Barry Hottmann expressed his condolences to the Segebrecht family, saying her death is an unimaginable loss.

“The pain of such a senseless act of violence is something no family should have to endure,” Hottmann said. “Please know that our entire community mourns with you.”

Hottmann said Dodgeville is a community that looks out for one another, and he wanted people to know that it is a safe and strong community.

Mayor Hottmann also wanted residents to know there are resources available, especially for the Segebrecht family, for those who need support. This could be through local faith communities, city services or trusted organizations.

OMAHA, Neb. — Nebraska is suing Colorado over the amount of water it draws from the South Platte River, the latest in a long history of water rights disputes between the states that have been left increasingly dry by climate change.

Nebraska Gov. Jim Pillen and state Attorney General Mike Hilgers held a news conference Wednesday to announce the lawsuit, which was filed with the U.S. Supreme Court.

“It’s crystal clear. Colorado has been holding water back from Nebraska for almost 100 years and getting more and more egregious every single day,” Pillen said, pointing to Colorado’s rapidly expanding population over the past decade.

“So today it’s really, really simple: We’re here to put our gloves on,” Pillen said. “We’re going to fight like heck. We’re going to get every drop of water.”

Colorado Attorney General Phil Weiser called the lawsuit “unfortunate” in a written statement and said Nebraska officials failed “to look for reasonable solutions.” Gov. Jared Polis said the lawsuit was a needless escalation by Nebraska.

“Colorado has always been in compliance with the South Platte Compact and other applicable agreements. We have also continued to meet in good faith with Nebraska, despite its attempts to intimidate Colorado landowners and damage our agricultural communities,” Polis said in a statment.

The lawsuit accuses Colorado of depriving Nebraska of as much as 1.3 million acre-feet (about 160,350 hectare-meters) of water from the river over several years that Nebraska is entitled to under a 1923 compact between the states.

The suit also accuses Colorado officials of blocking Nebraska’s effort to construct a massive canal — often called the Perkins County Canal — and reservoir project that would see Nebraska seize land in Colorado to divert water into Nebraska, which is also allowed under the compact.

Nebraska needs the water not only for agriculture production in its southwestern region — which climate experts predict will grow hotter and drier in the coming decades — but also to feed water supplies in the eastern part of the state, officials said. Nebraska’s capital, Lincoln, is expected to get 12% of its water from the proposed canal, Pillen said.

The compact entitles Nebraska to 120 cubic feet (3.4 cubic meters) per second from the river during the irrigation season between April 1 and Oct. 15 each year, and 500 cubic feet (about 14 cubic meters) per second during the non-irrigation fall and winter months.

Hilgers said Colorado has been shortchanging Nebraska during the irrigation season, allowing only about 75 cubic feet (about 2 cubic meters) per second of water daily into Nebraska this summer.

“I think this may be the most consequential lawsuit that this office will be a part of in my generation,” Hilgers said. “It is almost impossible to overstate the importance of the South Platte River to the future of the state of Nebraska.”

The South Platte, which flows through northeastern Colorado into southwestern Nebraska, has been at the center of a tempest brewing between the two states going back to 2022, when Nebraska announced it would build the canal.

Since then, officials from the two states have been haggling over how to carry out both the terms of the compact and land acquisition to build the canal.

“It became clear, despite the very professional and intentional scope of those negotiations, that we were at an impasse,” Hilgers said.

Weiser countered that Nebraska officials should have remained at the negotiating table.

“Nebraska’s actions will force Colorado water users to build additional new projects to lessen the impact of the proposed Perkins County Canal,” he said. “When the dust finally settles, likely over a billion dollars will have been spent — tens of millions of that on litigation alone — and no one in Nebraska or Colorado will be better off.”

Hilgers said the lawsuit was filed directly with the Supreme Court because it handles disputes between states. The process “isn’t fast,” Hilgers warned.

“We’ll probably have a special master appointed within the next 12 months, and under normal litigation timelines, that’s maybe 3 to 5 years before we get a result,” he said.

That does not mean work on the canal will stop, he said, as he expects work on permitting and design of the canal to continue.

Nebraska has been at the center of interstate water disputes for decades. In 2002, Nebraska, Colorado and Kansas reached a settlement over Republican River water allocation after years of legal wrangling. But disputes continued, and new agreements were reached among the states again in 2014.
