Chandler Halderson

On July 7, 2021, a 23‑year‑old man walked into a precinct in Dane County, Wisconsin, and told deputies his parents were missing. ^[1]

Chandler Halderson said Bart and Krista, his mother and father, had gone to the family’s cabin over the Fourth of July weekend and never come home. ^[1][2]

Within days, investigators would find Bart’s dismembered remains on a farm outside town and more remains belonging to Krista near the Wisconsin River. ^[1] What began as a missing‑persons case in the quiet suburb of Windsor would spiral into a story of elaborate lies about college and work, a digital trail on Snapchat, and a son convicted of murdering both his parents.

The Haldersons and the First Signs Something Was Wrong

Bart and Krista Halderson lived in Windsor, Wisconsin, and had two adult sons, Mitchell and Chandler. ^[2] Mitchell was 24, Chandler 23. ^[2]

Krista’s cousin, Barbi Townsend, would later describe her as “a very happy person” who poured her heart into her two boys. ^[1] The family projected stability: a suburban home on Oak Spring Circle Drive, a shared cabin “up north,” and two sons making their way into adulthood. ^[2]

The first public sign that anything was wrong came on Friday, July 2. Krista did not show up for work and did not call in—behavior that immediately worried her coworker and close friend, Daniel Kroninger. ^[2] He texted and called her several times that day and got no response. ^[2]

A Story About the Cabin

Over the holiday weekend, Kroninger continued to check in with Chandler, asking whether he had heard from Bart and Krista. ^[2] Chandler told him his parents had poor cell service at the cabin and claimed that messages might come through when “the clouds clear.” ^[2]

He also told people an unknown couple had picked up Bart and Krista and driven them to the cabin. ^[2] On Sunday, July 4, Chandler said he had talked to his parents and that they would be back home on Monday. ^[2]

But Monday, July 5, came and went. Krista still did not show up for work—nor on Tuesday, July 6. ^[2] By Wednesday, July 7, Kroninger had heard enough. He pushed Chandler to file an official missing‑persons report. ^[2]

That same day, Chandler walked into a precinct and reported his parents missing, telling law enforcement they had gone to the family cabin for the Fourth of July weekend and hadn’t returned. ^[1][2]

Detectives at the Windsor Home

Detectives Sabrina Sims and Brian Shunk of the Dane County Sheriff’s Office were assigned to lead the missing‑person investigation. ^[2] When they first went to the Halderson home on Oak Spring Circle Drive, only Chandler was there. ^[2]

Inside, Chandler pointed out items he said his parents had taken with them on their trip to the cabin. ^[2] Outside, both Bart and Krista’s cars were still parked in the garage, an immediate red flag for investigators. ^[1]

The Cabin That No One Visited

The Halderson family cabin was a remote lakeside retreat built by Krista and Barbi’s grandparents in the 1940s—a place woven into family history. ^[2]

The day after Chandler filed the missing‑persons report, Mitchell and his fiancée drove about three hours north to search the cabin themselves. ^[2] They went in with police. Inside, the cabin was dark; there were no signs that Bart or Krista had been there. ^[2] The canoe sat in the shed, undisturbed, and it was apparent to investigators that no one had visited in a long time. ^[1][2]

Back in Windsor, Chandler was captured on a neighbor’s doorbell camera going door to door asking whether anyone had seen or heard from his parents. ^[2] When local reporters, including journalist Adam Duxter, came to the house, Chandler agreed to a voice‑recorded interview but declined to be filmed. ^[2]

He continued to repeat versions of the story that his parents had left with an unknown couple to go up north, even as the evidence at the cabin suggested otherwise. ^[2]

A Farm Outside Town, and a Car in the Woods

Investigators soon got a tip from the owner of a farm outside Cottage Grove, a community about 20 miles from the Halderson home. She reported that Chandler had been on her property over the Fourth of July weekend. ^[2]

According to the farm owner, Chandler was there with a couple on July 4 and returned alone the next day, July 5. ^[2] Separately, a resident of Cottage Grove reported seeing Chandler on July 5 backing his car up near a wooded area and later watched him walk out of the woods, behavior the witness found unusual. ^[1]

The wooded area where Chandler had been seen was part of the same farm. ^[2] Detectives learned that the farm belonged to the family of Chandler’s girlfriend, Cathryn Mellender. ^[1] They asked both Chandler and Mellender to come in voluntarily for interviews. ^[1]

As these tips came in, deputies moved to search the property.

The Discovery of Bart Halderson

On Thursday, July 8, 2021, while deputies were searching the farm about 20 miles from the Halderson home, they discovered human remains in the woods—those of an adult male. ^[2] Police found a torso at the wooded site; it would later be identified as Bart Halderson. ^[1][2]

Near the remains, investigators found cutting instruments hidden in or near an old oil drum, including scissors, pruning shears, and a broken bow saw. ^[2] Another report noted scissors, a saw blade, and bolt cutters in the drum as well. ^[1]

An autopsy revealed that Bart had been shot and then dismembered. ^[1] Preliminary results showed he had been shot at least twice in the back. ^[2]

From Concerned Son to Prime Suspect

After learning that Chandler had been at the farm, police picked him up and brought him to the station for questioning. ^[2] In a recorded interview, Chandler said the last time he had seen his parents was Thursday morning and thought it was about 6 a.m. ^[2] He told detectives that while they were eating dinner, Bart and Krista said they were going up north to the cabin. ^[2]

By then, detectives were not just checking his story; they were treating him as a person of interest. ^[2]

While tests were still being done to confirm the identity of the remains found on the farm, detectives arrested Chandler and charged him with lying to police. ^[2] Officially, he was arrested for allegedly providing false information to investigators about the missing persons report. ^[1] Sheriff Kalvin Barrett later explained that the arrest was based on Chandler supplying false information regarding a missing person. ^[2]

In the days following his arrest, Chandler was held in jail on a tentative charge of first‑degree intentional homicide while authorities worked to confirm whose remains had been found and how he had died. ^[1]

On Saturday, July 10, the male victim discovered in the woods was identified as Bart Halderson. ^[2]

A Digital Trail to the Wisconsin River

Even with Bart’s remains identified, Krista was still missing. Investigators turned to technology. They used Snapchat’s Snap Map feature—the app’s location‑sharing option—to trace Chandler’s movements around the holiday weekend. ^[1]

Snap Map data showed Chandler at the Wisconsin River on July 3, 2021. ^[1] Acting on that digital lead, and on a separate tip from a neighbor who lived near the river, investigators searched the area. ^[1]

There, near the riverbank, they found more human remains. Those remains were later determined to belong to Krista Halderson. ^[1]

Dane County Sheriff’s Office detectives Sabrina Sims and Brian Shunk would later say they believed Bart and Krista had been killed in the basement of their Wisconsin home, though their remains were ultimately discovered at the farm outside Cottage Grove and near the Wisconsin River. ^[1][2] The exact sequence of what happened inside the house before their bodies were moved has not been fully detailed publicly, but to investigators, the picture that emerged was one of a crime carried out at home and concealed in pieces across multiple outdoor sites.

Clearing the Girlfriend, Fixing on Chandler

The discovery that the Cottage Grove farm belonged to the family of Chandler’s girlfriend, Cathryn Mellender, demanded careful scrutiny. ^[1] Investigators brought Mellender in for questioning and examined her possible role. ^[1]

The Web of Lies About School and SpaceX

While search teams combed woods and riverbanks, another part of the case unfolded in phone records and emails.

Chandler had been telling people he had an internship at an insurance company and a job lined up at SpaceX. ^[2] Prosecutors later argued that the supposed SpaceX job was a lie. ^[1]

At the same time, questions were mounting about Chandler’s college enrollment. Madison College Enrollment Officer Omar Jobe said Bart called the school posing as Chandler, trying to get his son’s transcripts. ^[1] Investigators said Bart had been trying unsuccessfully for months to obtain those transcripts and was growing suspicious. ^[1]

According to prosecutors, Bart’s call was a ruse to confirm whether Chandler was actually enrolled in college, and they told the court that Chandler had in fact failed out of school. ^[1] Prosecutors also alleged that Chandler set up fake email accounts to deceive his father about why transcripts were not appearing, spinning out excuses and explanations from invented senders. ^[1]

In their telling, by early July 2021, Chandler’s double life—fabricated classes, imaginary jobs, and a fictional SpaceX future—was under direct threat from his father’s questions. ^[1] At trial, prosecutors would argue that this looming exposure was the motive for murder. ^[1]

Inside the Trial

Aftermath, Vacated Counts, and an Appeal

In April 2023, a court vacated two of Chandler’s lesser convictions for hiding a corpse. ^[1] His life sentence for the murders remained. Chandler has filed an appeal in the case, seeking to challenge aspects of his conviction and sentence. ^[1]

For Bart and Krista’s loved ones, the legal maneuvers do not change the brutal facts: a frugal father shot and dismembered, a devoted mother whose remains were scattered along a river, and two sons split by a crime that left one imprisoned for life and the other searching a dark, empty cabin for parents who were already gone. ^[1][2]

The investigation traced a path from a tipped coffee table in a Windsor living room to a remote cabin, a girlfriend’s family farm, and the banks of the Wisconsin River. ^[1][2] Along the way, tips from neighbors, a farm owner, and the location‑sharing feature of a social media app helped detectives dismantle the story Chandler told when he walked into that precinct and said his parents had simply gone up north and never come back. ^[1][2]
