The man walking the woods in Cass County, Missouri, was looking for mushrooms. It was April 3rd, 2017, and he kept his eyes on the forest floor, scanning the damp earth for signs of new growth after the long winter. Then he stopped. Partially buried beneath the decay of seasons was a human skull.

He backed away and called the authorities. Police descended on the remote location, cordoned it off, and began a slow, methodical search. The next day, they uncovered a second set of human remains nearby. Two bodies, left in the same isolated patch of earth.
Two young women, separated by nearly a decade, now lying in the same makeshift grave. The connection between them was a man who had been hiding in plain sight. Before she was a name in a case file, Jessica Runions was a daughter, a sister, and a friend known for her bright, magnetic energy. At 21, she was stepping into a future she was building for herself.
Hard-working and dedicated, she had just earned a promotion to a management position and was making plans to study journalism in college. Her family described her as the kind of person others were naturally drawn to—vibrant, full of life, and fiercely loyal to the people she loved. Her parents, Jaime and John Michael, knew her as dependable to a fault. She was in constant contact with them, a steady presence in their lives.
On the evening of September 8th, 2016, Jessica attended a gathering at a friend’s house in Grandview, Missouri. Among the attendees was Kyler Yeast, a man she knew as a childhood friend of her boyfriend. As the night wore on, the atmosphere began to change. Witnesses later recalled that Yeast was drinking heavily, his behavior becoming increasingly erratic.
He focused his attention on Jessica, growing possessive and argumentative. The tension was palpable, a dark undercurrent to the social gathering. Despite the obvious friction between them, as the party wound down, Jessica was seen leaving with Yeast. They walked out of the house and got into her black 2012 Chevrolet Equinox, disappearing into the night.
It was the last time anyone besides the man in the passenger seat would see her alive. The next morning, a sense of unease crept into the Runions household. Jessica had a follow-up doctor’s appointment scheduled for a recent appendectomy. It wasn’t an appointment she would ever miss.
Her mother, Jaime, called her phone, but the calls went straight to voicemail. Texts went unanswered. This was not like Jessica. The hours ticked by, each one filled with mounting dread.
Every possible excuse, every rationalization, eventually gave way to a terrifying certainty. Something was deeply wrong. Trusting a mother’s intuition that cuts through all logic, Jaime Runions picked up the phone, her hands trembling, and reported her daughter missing to the police. The search for Jessica had officially begun.
Less than 48 hours later, a call came in to the Kansas City Fire Department. A vehicle was ablaze, abandoned in a wooded area near an underpass. When the flames were extinguished, authorities confirmed the worst. The scorched metal shell was all that remained of Jessica’s Chevrolet Equinox.
The vehicle was empty. The discovery was a brutal message. Any lingering hope that this was a simple case of a young woman needing time away was instantly erased. The fire was a deliberate attempt to obliterate evidence.
This was no longer a search for a missing person. It was now a homicide investigation. With the car found, the focus narrowed with incredible speed onto one man: Kyler Yeast. He was the last person seen with Jessica, and witnesses confirmed he left the party with her in that very vehicle.
On September 11th, just one day after the SUV was found, police located and arrested Yeast in Benton County, Missouri. He had visible burns on his body—a damning piece of physical evidence. But with no sign of Jessica, they couldn’t charge him with her disappearance. Instead, he was charged with knowingly burning her vehicle.
While investigators questioned him about where Jessica was, Yeast remained evasive, offering nothing. The key suspect was in custody, but the central mystery remained locked behind his silence. As detectives dug into Kyler Yeast’s background, they uncovered a history that sent a shockwave through the investigation. This was not his first time at the center of a young woman’s disappearance.
For nine long years, the community of Belton, Missouri, had been haunted by the cold case of 17-year-old Kara Kopetsky. She had vanished in May of 2007, and the last person known to have had contact with her was her ex-boyfriend, Kyler Yeast. He was, and had always been, the only person of interest in her case. The parallels between the two cases were undeniable and deeply disturbing.
Kara Kopetsky, like Jessica, had been involved with Yeast and had tried to distance herself from him. Her disappearance on May 4th, 2007, came just days after she filed a restraining order against him. In it, she detailed a pattern of controlling and violent behavior, including accusations that he had kidnapped her. For nine years, her family had searched for answers, living in a state of suspended grief, while the man they believed was responsible walked free.
Now, with Jessica gone, investigators faced a terrifying possibility. This wasn’t a tragic coincidence. They were looking at a clear pattern of predatory violence, and the disappearances of two women nearly a decade apart were now fused into one urgent overarching inquiry. With Kyler Yeast held on an arson charge but no new leads on Jessica’s location, the official large-scale search was soon suspended.
For the authorities, the case had hit a wall. But for the Runions family, giving up was not an option. They refused to let Jessica’s memory fade into a cold case file. Their home, once a place of family comfort, was transformed into a command center.
The walls were lined with maps of Cass and Jackson counties, marked with grids and highlighted sections. Every day they coordinated with an army of volunteers—friends, neighbors, and strangers moved by their plight—organizing search parties that combed through fields, forests, and waterways. They lived in a state of constant motion, fueled by a sliver of hope and an unbreakable determination to bring their daughter home. For seven months, they searched.
Seven months of agonizing uncertainty, of holding their breath with every phone call and steeling themselves against every false lead. They waited for a breakthrough, praying for an answer while dreading what that answer might be. That breakthrough finally came on April 3rd, 2017. When the man hunting for mushrooms stumbled upon a human skull, authorities arriving at the scene knew this could be the discovery the Runions and Kopetsky families had been waiting for.
The area was sealed off and a meticulous search began. The next day, their efforts yielded a second skull found nearby. The location, as prosecutors would later note, was a place Yeast knew well—one of his spots. The remains were carefully transported to the Jackson County Medical Examiner’s Office, where the difficult task of identification began.
For the families, it was the start of one final agonizing wait. On April 6th, just three days after the initial discovery, the first confirmation came. One set of remains belonged to Jessica Runions. Months later, the second set was positively identified as Kara Kopetsky.
The horrifying truth was now undeniable. Two young women, taken nearly a decade apart, had been left in the same desolate place by the same man. The discovery brought a devastating end to years of uncertainty. Their daughters had been found.
It was the worst possible news. Yet it provided a tragic, necessary closure and cleared the path for the final pursuit of justice. In October 2017, with the remains of his victims identified, Kyler Yeast was formally charged with two counts of first-degree murder. But the path from charge to trial was anything but straightforward.
The case was plagued by years of legal delays, motions for a change of venue due to the intense media coverage, and competency evaluations for Yeast. The prosecution also faced a major setback in 2018 when a key witness—Yeast’s half-brother, Jessup Carter—died by suicide while in custody. Carter had previously told police that Yeast had confessed to strangling Jessica, and his death removed a critical piece of testimony from the board. When the trial finally began in April 2021, the prosecution faced a significant challenge.
There was no direct forensic evidence, like DNA, linking Yeast to the killings. Instead, they built their case on a mountain of circumstantial evidence. They painted a portrait of Yeast as a pathologically jealous and controlling man who flew into a rage when the women in his life tried to leave him. The foundation of their case was Yeast’s own words.
Over the years, he had confessed to at least six different people. Jurors heard from friends and acquaintances who testified that Yeast had admitted to the killings. The most powerful piece of evidence was a 2011 FBI wiretap recording, captured during a separate investigation, in which Yeast appeared to confess to strangling Kara Kopetsky, saying he had choked her until she was gone. Yeast’s defense team fired back, attacking the integrity of the police work.
They argued the investigation was suspect-driven, claiming that law enforcement had zeroed in on Yeast from the very beginning and failed to properly investigate other leads. They presented an alternate theory, attempting to shift the blame for the murders onto Yeast’s deceased half-brother, Jessup Carter. They suggested Carter was the real killer—a convenient but unsubstantiated claim against a man who could no longer defend himself. The trial reached its dramatic peak when Kyler Yeast took the stand in his own defense.
In a calm and steady voice, he denied any involvement in the deaths of Jessica Runions and Kara Kopetsky. When confronted with the numerous confessions he had made over the years, Yeast offered a stunning explanation. He claimed it was all an act. He told the jury he was simply trying to impress an ex-girlfriend who he believed was attracted to his dark reputation.
He wasn’t confessing to murder. He claimed he was just playing a part. The jury was left to decide. Was Kyler Yeast a victim of his own foolish bravado, or was he a calculated predator trying to lie his way out of two murders?
After a nine-day trial, the case went to the jury. For 15 hours, they deliberated, weighing the mountain of circumstantial evidence against the defense’s claims of a flawed investigation. Finally, they returned. The courtroom held its breath as the verdict was read.
In the death of Kara Kopetsky, they found Kyler Yeast guilty of the lesser charge of voluntary manslaughter. For the death of Jessica Runions, they found him guilty of second-degree murder. While it wasn’t the first-degree murder conviction prosecutors had hoped for in Kara’s case—a reflection, perhaps, of the decade-old evidence—the verdict was an affirmation. After years of evading accountability, Yeast was found responsible for both deaths.
During the sentencing phase, the families were finally given the chance to confront the man who had caused them a decade of unimaginable pain. Jessica’s mother, Jaime Runions, spoke of the longest four years and seven months of her life—a constant, unending search for her daughter. Kara’s mother, Rhonda Beckford, described her family’s ordeal as a ten-year nightmare. Their statements were not just expressions of grief but powerful testaments to their daughters’ lives and their own relentless fight for this day in court.
The jury recommended the maximum possible sentences for the convictions. And on June 7th, 2021, the judge agreed. Kyler Yeast was sentenced to 15 years for manslaughter and 30 years for second-degree murder, with the sentences to be served consecutively—a total of 45 years in prison. Yeast’s legal team would later file an appeal, but in August 2023, the Missouri Court of Appeals denied all points and affirmed the judgment.
The legal battle was officially over. The man who had haunted two families for over a decade would remain behind bars. The case against Kyler Yeast is a harrowing chronicle of loss, but it is also a testament to the enduring power of familial love and the relentless pursuit of justice. His violent actions stole the futures of two young women and inflicted years of pain on their families and community.
The investigation stands as a crucial lesson on the importance of recognizing patterns of domestic abuse and the connections that can link cases over many years. The perseverance of the Runions and Kopetsky families transformed their private grief into a public fight, ensuring a dangerous predator was finally held accountable. Ultimately, this story belongs to them. Jessica Runions and Kara Kopetsky were more than victims.
They were bright, beloved young women whose lives were cut short. Their memories are honored not just in the verdict, but in the fight for justice that was waged in their names.
