Chandler Halderson

On a summer afternoon in rural Dane County, Wisconsin, officers followed a tip to a quiet farm tied to a young man’s girlfriend. Hidden near the tree line, they found a mutilated torso with multiple bullet wounds. It belonged to 50‑something father Bart Halderson.^[1][2]

The day before, Bart and his wife, Krista, had been reported missing by their 23‑year‑old son, Chandler.^[1][2] Within hours of the discovery, that same son would be under arrest—and, eventually, convicted of killing and dismembering both of his parents.

A Close-Knit Family, A Promising Son

Chandler Michael Halderson was born March 15, 1998, and grew up in Wisconsin.^[1] His parents, Bart A. Halderson and Krista Rae (Frater) Halderson, raised him in a suburban home north of Madison.^[1][2]

Family members later described Krista as outgoing and deeply devoted to her two sons. Her cousin, Barbi Townsend, recalled her as “very happy” and “devoted” to her boys.^[2] Townsend said Bart and Krista “would have given everything and anything to help him.”^[2]

From the outside, the Haldersons looked like a stable, supportive family. There was a cabin up north in Langlade County, a familiar Fourth of July tradition, and a grown son who said he was enrolled in college and mapping out a future in tech.^[1][2]

That image would unravel in a matter of days.

The Missing-Parents Call From Windsor

The case began on July 7, 2021, when Chandler called authorities to report his parents missing from their home in Windsor, Wisconsin.^[2]

He told investigators that Bart and Krista had left for their family cabin in Langlade County over the Fourth of July weekend with another couple and had never arrived.^[1][2] Dane County Sheriff’s Detective Sabrina Sims later said Chandler mentioned his parents were “maybe going to a casino” as part of their plans.^[2]

Investigators went to the Halderson home. Both parents’ cars were still sitting in the garage.^[2] That alone made their supposed weekend getaway hard to believe.

Officers then drove hours north to the family’s cabin in the Wolf River area. There were no signs anyone had been there recently—no fresh tire tracks, no evidence of guests, nothing to support the story of a holiday trip gone wrong.^[2]

By the end of that first day, the Haldersons’ disappearance was no longer just a standard missing-person case. The narrative their son had offered didn’t match what detectives were seeing on the ground.

A Witness, a Farm, and a Torso

The break came from a neighbor in Cottage Grove. She reported that on July 5, she’d seen Chandler backing his car up near a wooded area and later walking out of the trees alone—behavior she found strange enough to mention to police.^[2]

Following that lead, investigators searched the wooded property where she’d seen him. There, they discovered a human torso—later identified as Bart Halderson’s.^[1][2] The remains showed several bullet wounds, and an autopsy concluded Bart had been shot and then dismembered.^[1][2]

Nearby, in an oil drum, officers found scissors, a saw blade, and bolt cutters.^[2] It looked like a makeshift disposal site.

Detectives traced the land itself and learned the farm belonged to the family of Chandler’s girlfriend, Cathryn Mellender.^[2] They brought both Mellender and Chandler in for voluntary interviews.^[2]

Searching the same property, investigators recovered a rifle that they determined belonged to Chandler.^[1]

That night—July 8, 2021—Chandler was arrested, not yet for murder but for allegedly lying to detectives about his parents’ disappearance and providing false information.^[1][2] In the days that followed, he was held in jail on a tentative charge of first-degree intentional homicide.^[2] A formal probable cause statement would be dated July 9.^[1]

Snap Map and the Wisconsin River

With Chandler in custody, attention shifted to finding Krista. The torso in Cottage Grove accounted only for Bart; Krista was still missing.

Mellender turned over digital evidence from her Snapchat account to investigators.^[2] Among it was location data—Snapchat’s “Snap Map” feature—which showed Chandler at the Wisconsin River on July 3, 2021.^[2]

Armed with that timestamp and a separate tip from a neighbor near the river, investigators searched along the banks outside the small community of Roxbury.^[2] On July 14, 2021, they found a pair of severed legs near the Wisconsin River, in a spot Chandler was known to visit.^[1] The remains were identified as belonging to Krista Halderson.^[1]

Because only her legs were recovered, the specific cause of Krista’s death could not be determined.^[1]

By then, Chandler had already been charged with killing and dismembering both of his parents.^[1] The counts ultimately included two charges of first-degree intentional homicide, providing false information on missing persons, mutilating a corpse, and hiding a corpse.^[1]

Investigators came to believe that Bart and Krista had been killed in the basement of their Wisconsin home before their bodies were taken to different sites.^[2] They also said they determined early on that Mellender had no role in the murders and formally cleared her.^[2]

A Web of Lies, According to Prosecutors

By January 2022, Chandler—who also went by “Chaz”^[1]—was set to stand trial. He pleaded not guilty to all eight charges he faced.^[1][2] Opening statements began on January 4, 2022.^[1]

In the courtroom, the state presented a detailed theory: that Chandler’s life was built on lies, and that those lies were starting to collapse.

Prosecutors argued he murdered Bart and Krista after they began to uncover deceptions about his education, employment, and future plans.^[1][2]

They told jurors that Chandler repeatedly claimed he was attending Madison Area Technical College, often called Madison College.^[1] Enrollment officer Omar Jobe testified that Bart had called the school, pretending to be his son, to try to obtain Chandler’s college transcripts.^[2] Investigators said Bart had been trying to get those transcripts for months and was growing suspicious.^[2]

According to prosecutors, Bart’s call was a deliberate ruse to find out whether his son was actually enrolled—and the answer was no. They said Chandler had already failed out of school.^[2]

The state further alleged that Chandler had gone to elaborate lengths to keep the truth from his parents, including creating fake email accounts posing as school employees to explain away transcript “issues.”^[2]

Prosecutors said the lies didn’t stop at school. They told the jury Chandler claimed to work for the local branch of American Family Insurance.^[1] They also argued that he boasted of a future with SpaceX, saying he planned to move to Titusville, Florida, with Mellender for a job there—claims prosecutors insisted were pure fabrication.^[1][2]

As for what happened in the days before the Haldersons were reported missing, prosecutors laid out a grim narrative. They alleged that Bart called Madison Area Technical College directly and learned Chandler was not enrolled.^[1] According to their theory, Bart then planned to attend a meeting at the college with Chandler. Instead, prosecutors said, Chandler shot his father in the back with a high-powered rifle that had been gifted to him by a friend.^[1]

They alleged that after killing Bart, Chandler texted his mother, Krista, and killed her when she came home.^[1]

From there, prosecutors told jurors, Chandler dismembered both of his parents’ bodies and scattered remains across southern Wisconsin—on the Mellender family farm in Cottage Grove and near the Wisconsin River in Roxbury.^[1][2]

Dane County Sheriff’s Office Detectives Brian Shunk and Sabrina Sims later said they believed both Bart and Krista had been killed in the basement of the couple’s home before being transported to those sites.^[2]

“A Liar, Not a Killer”: The Defense Fights Back

Chandler’s defense team pushed back hard on the state’s version of events.

His lead attorney, Crystal Vera, leaned directly into the portrait of her client as a fabulist, but argued that deception did not equal murder. “All the State was able to prove is that Chandler is a liar, not a killer,” she told jurors.^[2]

Jurors heard about Chandler’s fabricated school and job history, his convoluted email schemes, and the shifting explanations he gave investigators about his parents’ whereabouts.^[1][2] The defense did not contest that he had lied repeatedly; instead, they questioned whether the physical and digital evidence truly proved he had carried out the killings and dismemberments himself.

But the tools in the Cottage Grove oil drum, the rifle linked to Chandler, the Snap Map placing his phone at the river where Krista’s remains were found, and his own false reports to police formed a tight circle of circumstantial evidence.^[1][2]

Conviction, Life Sentences, and Narrowed Appeals

On March 17, 2022, the jury returned its verdict. Chandler Halderson was found guilty on all eight charges.^[1][2]

That same day, he was sentenced to life in prison without the possibility of parole.^[1][2] Court records reflected two life sentences, ensuring he would never be released.^[1]

In the months that followed, Chandler pursued multiple appeals.^[1][2] In April 2023, two of his lesser convictions for hiding a corpse were vacated, but his homicide convictions and life sentences remained untouched.^[2]

On June 16, 2026, the Wisconsin Supreme Court declined to review his case, effectively closing off his last major avenue for relief in state court.^[1]

By then, the Chandler Halderson murders had become one of Wisconsin’s most notorious family homicide cases. ABC News and the program “20/20” devoted a special to the story in an episode titled “Wisconsin parents murdered over college lies: How Snapchat helped uncover the truth,” published May 30, 2025.^[2]

The Human Cost Behind the Headlines

Strip away the courtroom theories and digital breadcrumbs, and what remains is the abrupt destruction of a family that, by many accounts, centered itself around its children.

Relatives remember Krista as joyful and deeply invested in her sons’ lives.^[2] Bart, they said, was careful with money and not the sort to vanish for a gambling trip on a whim.^[2] Together, according to Townsend, they “would have given everything and anything” to support Chandler.^[2]

Instead, their last chapter is written in crime-scene searches across farm fields and riverbanks, in tools burned in an oil drum, and in a son’s lies laid out in court.^[1][2]

For those who knew Bart and Krista Halderson, the most enduring mystery is not the forensic timeline or the Snapchat pings. It is how two parents so determined to help their child ended up dismembered in the Wisconsin summer, with that same child serving life sentences for their murders.
