North Dakota 1987 Cold Case SOLVED – The Truth Broke Everyone’s Heart

39 years ago, in the early hours of October 25, 1987, a quiet gravel road north of New Rockford, North Dakota, was lit up by something that had no business being there. A burning car. Flames eating through metal and glass in the dead of night on a stretch of road near a railroad crossing that almost nobody used at that hour.

 When firefighters arrived and brought the fire under control, they opened what was left of the car, a 1974 Ford Torino, and found the body of 35-year-old Kathy Bondes on the front seat. Kathy was a nurse, a mother, a wife, and now she was dead. Her body charred inside a car on a remote in the middle of the night with no witnesses and no obvious explanation.

What followed was one of the most frustrating cold cases in North Dakota history. A case where the truth was buried under bad decisions, missed opportunities, and a killer who walked free for nearly two decades. Because the person responsible for Kathy Bonderson’s death was not some stranger passing through town.

 The culprit had been hiding in plain sight from the very beginning. To understand what happened that night, you have to go back a few hours earlier to the argument that started it all. It was just after 2:00 in the morning on October 25th, 1987. Inside the Bondes home, Kathy and her husband, Robert, were in the middle of a heated fight.

 Their teenage son, Jaime, had not come home, and nobody knew where he was. Robert made a brief attempt to find the boy, driving around for a short time before giving up and returning home without any answers. Kathy was not willing to leave it at that. She was also running late for her shift at the convolescent hospital where she worked as a nurse.

 Frustrated with Robert and worried about her son, she decided to go look for Jaime herself. She got in her 1974 Ford Torino and drove off into the night. What she did not know, what none of them knew in that moment, was that Jaime was not lost at all. He was parked with his girlfriend near a bridge, doing exactly what teenagers do when they do not want to be found.

 When Jaime spotted his mother’s car coming down the road, he immediately ducked down in his seat, hoping she would pass by without noticing him. She did pass by, and Jaime, peeking up just enough to watch her go, noticed something else. Another car was following closely behind hers, moving in the same direction, keeping pace.

 He thought little of it at the time, just another car on the road. That was the last confirmed sighting of Kathy Bonderson alive. Jaime would later tell police what he saw that night. And his girlfriend sitting right there beside him in that parked car would eventually share something far more significant. Something she had written down in her diary that very night.

 A detail so specific, so quietly powerful that it would help crack the case wide open decades later. About an hour after Cathy set out to find her son, her car was found burning on that gravel road near the railroad crossing. Firefighters put out the fire, found her body, and called in the authorities.

 Sheriff Edor Maris arrived and began piecing together what he believed had happened. His theory went like this. The fire had started at the front of the car. For some unknown reason, Kathy had swerved to the right as she approached the railroad crossing, sending her car over the exposed tracks and down into a ditch.

 The impact of the crash had thrown her from the driver’s seat into the front passenger side. The crash had then caused the car to catch fire. “It was a tragic accident,” Alaris concluded. A terrible, senseless accident on a dark road in the middle of the night. But not everyone at that scene was satisfied with that explanation.

 State Highway Patrolman William Byum was also there and from the very beginning something felt wrong to him. He started looking more carefully at the details that did not quite fit the accident theory and what he found gave him serious pause. The first thing that caught his attention was the car keys.

 Despite the intense heat of the fire, heat that had melted significant portions of the car’s interior. Cathy’s keys were found on the floorboard of the vehicle, remarkably undamaged. If the car had crashed hard enough to throw Cathy across the seat and trigger a fire that melted the interior, why were the keys in such good condition? It was a small thing, but it nagged at him.

 Then there were the tire tracks, or rather the lack of them. Sheriff Almarass’s theory required that Kathy had swerved sharply off the road before hitting the tracks. But patrolman Byron searched carefully and found no tire tracks that would support that story. There was no physical evidence on the ground of a car going off course the way Mara’s described.

 The marks that were on and near the tracks, Byron believed, had not been made by Cathy’s car at all. They had most likely been left by the heavy fire trucks that had responded to the scene. Byum was not ready to call this an accident. Not yet. Not until he had looked more closely. The following day, patrolman Byum returned to the scene with fire marshal Curt Fogle.

 Together, they conducted a detailed inspection of what remained of Cathy’s burned out Ford Torino, and what they found only deepened Byum’s suspicions. Despite the severe damage from the fire, there was no structural damage to the car consistent with a high impact crash. If the vehicle had careened off the road and slammed into a ditch with enough force to throw the driver across the car, there should have been clear signs of that collision in the body of the vehicle. There were none.

 Then came something even more puzzling. The car still had 12 gall of gasoline in the tank. 12 gallons. And when they examined the fuel line, it was undamaged, intact, which raised an obvious and deeply uncomfortable question. If the fire had not come from the car’s fuel system, where exactly had it come from? Fire marshall Fogle had the answer, and it was not the one Sheriff Almaras had hoped for.

 The fire, Fogle determined, had not started in one place, as you would expect from a crash or a mechanical failure. It had started in several distinct areas of the vehicle at the same time, multiple ignition points. That, Fogle concluded, was not an accident. That was arson. And it did not stop there. Forensic tests conducted on Cathy’s clothing and on the carpeting inside the car came back with traces of gasoline.

 The fire had been fed deliberately. Someone had poured gasoline inside that car and set it a light. And several days after the fire, a gasoline can was found near the scene, sitting out in the open as if it had simply been left behind. The picture was becoming clear to patrolman Byum. Kathy Bonderson had not died in a car accident. She had been murdered.

 Her body had been placed in that car. Gasoline had been poured over her and the interior. And the whole thing had been set on fire, staged to look like a tragic crash on a dark country road. 3 weeks after the fire, Byum decided he needed to push further. He formally advocated for the exumation of Kathy Bonderson’s body so that a proper autopsy could be conducted.

 If she had been alive when the fire started, her lungs would show it. Carbon monoxide would have entered her system as she breathed in smoke and fumes. If she had been dead before the fire, there would be nothing. Sheriff Alvarus pushed back. He did not want the body exumed. The case, in his view, was already resolved.

a tragic accident, nothing more. But Byum refused to drop it. He made it clear that if the sheriff would not authorize the exumation, he would go to the courts and get an order forcing it. Faced with that, Alarus relented. The autopsy was performed, and the result confirmed what Byum had feared and suspected.

 There was no carbon monoxide in Kathy Bonderson’s lungs. None. She had not breathed in a single breath of smoke. She had not been alive when that fire started. She was already dead when someone put her in that car and lit it up. Kathy Bonderson had been murdered before her body ever reached that gravel road.

 And yet, despite everything, the arson evidence, the absence of carbon monoxide, the gasoline traces, the multiple ignition points, the undamaged fuel line, the unmarked ground. Sheriff Ed Alarus refused to reclassify the case. He maintained that there was not enough definitive evidence to call it a murder. Officially, Kathy Bonderson’s death remained an accident.

 In April 1988, the county’s state’s attorney agreed with that position, writing in a letter that every avenue had been exhausted and the investigation should not continue. Patrolman William Byum disagreed with every fiber of his being. He believed a killer had walked free. He believed the evidence was right there for anyone willing to look.

 But without the backing of the sheriff or the prosecutor, there was nothing more he could do. The case went cold, and the killer, who had been hiding in plain sight the entire time, went on living his life. Sheriff Ed Alaras died in 1997, never having changed his position on the case. The Bonderson file sat in storage gathering dust while Cathy’s family spent years quietly carrying a grief that had no resolution.

 They had never believed it was an accident. They had always known something was wrong. But without official support, there was nothing they could do but wait. They waited for 18 years. In November 2005, North Dakota Attorney General Wayne Stenim announced the creation of a new cold case investigation team. And the very first case they would take on was Kathy Bonderson’s death.

 After nearly two decades, someone was finally going to take a serious look at what had really happened on that gravel road. The team led by Bureau of Criminal Investigation Agents Dallas Carlson and Dale Makesner went back to the beginning. They reintered everyone connected to the case. They studied every report that had ever been written, including all the autopsy records.

 They looked at old leads and developed new ones, and they ordered a new autopsy. This time, the results were unambiguous. The 2005 autopsy conclusively determined that Kathy Bonderson’s death was a homicide. Examining her remains, forensic specialists found injuries to her neck and throat that could not be explained by a car accident or a fire.

These injuries, they concluded, were the actual cause of her death. Someone had attacked Kathy Bonderson’s throat and neck. Someone had killed her. And then someone had put her body in that car and tried to make it look like she had never made it home. The case was now officially a murder investigation.

 And as any investigator will tell you, in a homicide, the first person you look at is always the spouse. Investigators arranged a formal interview with Cathy’s husband, Robert Bonderson, to be held on February 22nd, 2006. Robert had given a statement to the police shortly after his wife’s death back in 1987, but that had been when the case was still being treated as an accident.

 He had never been questioned as a suspect in a murder. Robert Bonderson did not show up for the interview. On that same day, February 22nd, 2006, he disappeared from his home in Thermopoulos, Wyoming. He left behind his bank accounts and his credit cards untouched. He simply vanished. For investigators, that disappearance spoke volumes.

 But they still needed to build the full picture of what had happened. And as they dug deeper into Robert Bonderson’s life, the details that emerged told a story of cold, calculated betrayal. In the months before Cathy’s death, Robert had begun a relationship with another woman, a woman named Nanette, then known by her maiden name, Woba.

 The affair had been going on while he and Kathy were still married, still living together, still raising their son Jaime, under the same roof. Then in August of 1987, just two months before Kathy was found dead in that burning car, Robert had taken out a $50,000 life insurance policy on his wife. 2 months later, she was dead.

 And then there was Jaime. When investigators spoke again with Cathy’s son about what he had seen that night from the parked car near the bridge, Jaime told them something he had apparently not shared or not been pressed on in the original 1987 investigation. He had seen his mother’s car that night. Yes, he had ducked down to avoid being spotted.

 Yes, but the person he had seen behind the wheel of that car was not his mother. It was his father. Robert Bonderson was driving Cathy’s car. At the time Jaime ducked down, he had seen his father at the wheel heading in the direction of that gravel road, heading toward the railroad crossing where Cathy’s body would be found an hour later.

 And Jaime had not been alone in that car near the bridge. His girlfriend had been right there beside him. She had seen it, too. And on that night, 19 years earlier, she had written it down in her diary, in her own handwriting. She had recorded what she witnessed. Robert Bonderson driving his wife’s car in the direction of the road where Kathy would be found dead.

 a teenager’s diary entry sitting untouched for nearly two decades, quietly waiting to become evidence. In April 2006, a recreational horseback rider exploring a remote mountainous area of Montana, roughly 50 mi south of Billings, came across something that ended the search for Robert Bonderson.

 His body was found in a secluded cabin deep in the wilderness, far from anyone who might have found him sooner. He had attempted to esphyxiate himself in his vehicle and when that failed, he had shot himself with a handgun. His vehicle was found nearby. Inside it, his current wife, Nanette, later discovered a handwritten card in which Robert claimed he had had nothing to do with Cathy’s death.

 Nobody believed him. The Eddie County State’s Attorney, Travis Peterson, stated publicly that had Robert Bonderson been alive, he would have been charged with murder and brought to trial. The current county sheriff echoed those words, thanking the Attorney General’s office for finally doing what should have been done years before.

 The investigation painted a clear and devastating picture of what had most likely happened on the night of October 24th and into the early hours of October 25th, 1987. Investigators concluded that Kathy Bonderson was almost certainly killed at her own home before she ever left the driveway. At some point during or after the argument, Robert attacked her.

 He killed her at the residence, then placed her body in the passenger seat of her own car. He then drove that car, the car Jaime and his girlfriend watched pass by near the bridge, out to a remote gravel road north of town, near the railroad crossing where almost nobody would be at that hour of the night.

 He poured gasoline over the interior and over Cathy’s body. He set the car on fire and walked away, leaving it to burn in the dark, expecting the fire to destroy the evidence and leaving a story that would hold. His wife had gone out looking for their son, had a terrible accident on a dark road, and never made it to work.

 He had gone back home. He had waited, and when news of the fire came, he had played the grieving husband while the insurance money, $50,000, sat waiting to be claimed. For 18 years, it had almost worked. The sheriff had called it an accident. The state’s attorney had closed the file, and Robert had moved on, remarrying, living in Wyoming, keeping his secret.

 But patrolman William Byum had never believed it. And eventually the truth had found its way back to the surface through a new autopsy, through patient investigative work, through a son’s memory, and through the diary of a teenage girl who had written down exactly what she saw on a quiet night in 1987 without knowing what it meant.

 Kathy Bondes’s case was officially closed following Robert’s death in April 2006. After nearly 20 years, her family finally had an answer. It was not the ending anyone would have wanted. No trial, no conviction, no moment in a courtroom where justice was formally delivered, but the truth had been established.

 Her family had waited nearly two decades, not even to hear the words accident reclassified, just to be believed. And in the end, they were. Attorney General Stenahhem noted at the time that the break in the case had not come from any new scientific technology or advanced forensic technique. It had come from thorough, methodical police work, rereading every old report, reintering every witness, following every thread until the full picture emerged.
