One morning, a 17-year-old girl walks out of her school in Belton, Missouri and is never seen alive again.
No struggle, no witnesses, no body—just gone.
But here’s what will haunt you about this true crime case: the man who killed her couldn’t keep his mouth shut.
Over the next 10 years, he confessed seven times to seven different people.
Investigators knew his name, they watched him, they questioned him repeatedly, and he still walked free—free long enough to kill again.
This documentary follows one of the most maddening cases in Missouri history: a decade of confessions that led nowhere, a family destroyed by silence, and a killer who hid in plain sight while the truth rotted in a field in Cass County.
It starts in 2007. It doesn’t end until two bodies are pulled from the ground in 2017.
And the question that will follow you long after this is over: how does a man confess to murder seven times and keep getting away with it?
You’re about to find out.
Belton, Missouri—a quiet, tight-knit city of about 26,000 people tucked into Cass County, just south of Kansas City.
Founded in 1871, it’s the kind of place where neighbors know each other, kids ride bikes after school, and nobody expects anything like this to happen.
But it did.
Among those 26,000 residents was Cara Kopetsky, born in 1990, the oldest child of Mike and Rhonda, and an older sister to her 8-year-old half-brother, Thomas.
People who knew Cara described her the same way every time: a firecracker, loud in the best way, the friend who told you exactly what she thought whether you asked or not.
She was also in every sense a normal teenager. She had insecurities, she changed her look constantly, she picked up smoking young.
At 16, she landed a job at Papa’s restaurant and showed up every shift—reliable, committed, responsible.
On the morning of May 4th, 2007, Cara was at school.
Just after 9:00 a.m., she had a free period. She walked out the door.
Her friends didn’t panic; skipping wasn’t exactly out of character for Cara.
But when the school day ended and her work shift came and went with no sign of her, her co-workers called her mother.
When her mother tried her phone, it was off. She called the police immediately.
When officers checked Cara’s room, everything was still there—her clothes, her savings, every single thing she would have taken if she’d left on her own terms.
This wasn’t a runaway. Something was very, very wrong and alarming.
The morning of May 4th, 2007, a school security camera captured Cara Kopetsky leaving Belton High School.
It would be the last time the 17-year-old would be seen alive.
Cara worked at this Popeye’s but didn’t show up. Calls and texts to her cell phone went unanswered.
Fearing for Cara’s safety, that same day a friend of hers went to Belton police, and after police talked with Cara’s family that night, she was reported as missing.
One week after she vanished, 41 Action News was invited inside the family’s home.
“You know, her dresser is full.”
In Cara’s bedroom, none of her clothes were missing. Her iPod and phone charger were left on a table.
“Something just is not right. I mean, she would not—she would not run off. I—I know she’s my daughter, and I know in my heart she would not do that.”
Her cell phone and debit card went unused.
“She’s not used or accessed her phone since the day of May 4th, uh, and that’s unusual for anybody with a cell phone, let alone a teenager.”
From the very first week, investigators had one name: Kyler.
Kyler was Cara’s ex-boyfriend. They’d been together for about 8 months, and from the outside, the attraction made sense.
He played in an underground metal band, he had the bad boy look, the edge, the attitude.
For a 17-year-old girl, that can feel magnetic.
But the people closest to Cara watched something shift.
The spark that made her her—the energy, the outspokenness, the fire—started fading.
And those who knew her best believed Kyler was the reason.
Eventually, Cara did what she had to do: she ended it.
Kyler refused to accept that.
About a week before she vanished, on April 28th, things escalated dangerously.
Cara walked out of work and Kyler was waiting. He forced her into his car and drove her miles away before letting her go.
She went straight to the Belton police and reported the abduction.
She obtained a protection order, officially served to Kyler on May 1st.
In that report, Cara described being restrained, choked. She said the abuse had been escalating and that she was afraid of what he might do next.
Three days after that protection order was served, Cara was gone.
When investigators brought Kyler in, he was calm, cooperative even.
He claimed Cara had called him that morning, but he missed it, tried calling back, got no answer.
He said he was at his grandfather’s place and then band practice—said he never saw her.
“He said that I wasn’t—that I was a suspect because of prior—because of prior happenings, not because of anything that would point to me having anything to do with her disappearing.”
“Now, you’ve been very cooperative.”
“Mhm, I have been, cuz I don’t have anything—I don’t know anything about where she is or about what happened. I wish I did.”
“You threatened to slaughter her throat.”
“No, I didn’t. What happened—that didn’t happen that night. That was before.”
But her phone records told a completely different story.
Cara called Kyler at 9:13 a.m. He called her back at 9:20, just 1 minute after she was last seen walking out of that school building.
One minute. That detail stopped investigators cold, and it would become the thread that unraveled everything.
Around the same time Cara vanished, another young woman named Kelsey Smith went missing less than 30 miles away, just one month later.
The community was gripped by fear. People started connecting dots that weren’t there.
But investigators confirmed the two cases were unrelated.
Kelsey’s body was recovered just 4 days after she disappeared.
Cara was different: no body, no evidence, no answers.
Search parties combed the area repeatedly. The community showed up, but the fields and woods of Cass County gave up nothing.
Slowly, quietly, the urgency began to fade. The case grew cold.
Through all of it, Cara’s mother never wavered. She knew who was responsible, and investigators agreed that Kyler was the last person to have contact with her daughter, directly contradicting everything he had told them.
But knowing something and proving it in a courtroom are two very different things. Without physical evidence, their hands were tied.
So they watched him, and Kyler kept giving them reasons to: drug charges, traffic violations, assault.
He was estranged from his family, diagnosed with bipolar disorder and PTSD, and battling serious substance abuse—cocaine at 14, heroin at 16.
Every time investigators pressed him about Cara, about the phone records, about the inconsistencies in his story, he asked for a lawyer.
Then came the confessions.
A former girlfriend, also a member of his band, told police that Kyler had admitted to killing Cara. Investigators asked her to get him to repeat it on record.
“Oh my god, just like felt her hand on my shoulder and I heard like… I—she didn’t say anything, it was just like her voice, like she just like, like, uh, just like, or something, like she just said like, just made a noise and it was…”
“Anything about the situation is convenient.”
“Well, it’s convenient for you because you get to sit up here and say, ‘My brother did it, and your brother’s not here to speak for himself.’”
“Right, and when you found out actually that the—that, uh, Jessup had killed himself, your response was, ‘I don’t fucking care.’ Right? This has been so hard for you, hasn’t it, Kyler?”
“It has been.”
“You were the target of this investigation for, quite frankly, almost 14 years, right?”
“Yes.”
“And testified about how you were acting on the night that you were pulled over. You remember his testimony?”
“I do, ma’am.”
“And you have peed yourself. That wasn’t me making that up, Kyler. You reiterated it several times with several different witnesses. I mean, jury remembers.”
“Well, they should, because you peed your pants because you were scared about getting pulled over. You didn’t get burned until you went and literally doused Jessica’s car in gasoline, and that gasoline flashed in your face, right?”
“No, burn barrel.”
“Yes, right. And you actually tell the jury that it hurt.”
“It did hurt.”
dishonesty
“You know what else would hurt? To have the life strangled out of you, right? Believe that is true, yes. Are you asking for some kind of empathy because you burned yourself when you were torching Jessica’s car?”
“No.”
“So you would rather sit in jail and be charged with two counts of murder in the first degree than to tell law enforcement that your brother allegedly was the one that did this.”
“I knew that I was getting blamed, and I knew that I’d have my chance to speak my peace right here on the stand, and that’s what I did.”
“You wait until a criminal trial, until a jury is literally sitting here deciding your fate, to tell your truth.”
The jury deliberated for nearly 2 days.
They came back with a verdict: guilty of voluntary manslaughter in the death of Cara Kopetsky, guilty of second-degree murder in the death of Jessica Runions.
On April 16th, 2021, 14 years after Cara walked out of that school building, Kyler Yust was sentenced to life plus an additional 15 years.
“On verdict form C, as to the count one, we the jury find the defendant, Kyler Yust, guilty of voluntary manslaughter as submitted in instruction number 15. Uh, as to count two, we the jury find the defendant, Kyler Yust, guilty of murder in the second degree as submitted in instruction number 22.”
In this case, under Missouri law, a life sentence carries 30 years, making his total time behind bars 45 years to be served consecutively.
The judge accepted every word of it and imposed the maximum penalties on both counts.
Kyler appealed. In 2023, the Missouri Court of Appeals shut it down completely.
“Everyone has shown tonight two families finally receiving the news they’ve waited for.”
“You know, we’re very thankful—thankful for justice to come.”
“Have you—did they refuse…?”
“Are you my post-conviction counsel? Have you been, uh, uh, able to talk to them about your case over the last, I think, four years?”
“What do you think? Any comment on the sentencing?”
“No.”
“Anything to say to the families?”
But for the families of Runions and Kopetsky, it was always about bringing the girls home after losing them too soon.
Cara’s mother had been right from the very beginning; it just took the world far too long to catch up.
And somewhere in a field in Cass County, two young women who never should have crossed paths with Kyler Yust were finally, after everything, given something that had been stolen from them for far too long: justice.
