Narrator
A missing tongue, footprints in the snow, unexplainable injuries, and a tent that was somehow still standing.
Carter Roy
When nine young Soviet hikers went missing in the Ural Mountains in the winter.
Narrator
Of 1959, the country rallied to find them. Eventually they did, but the hikers hadn't survived. In the immediate aftermath of the tragedy.
Carter Roy
Soviet officials declared their cause of death an insurmountable force of nature.
Narrator
The report was chillingly vague, and it opened the door for lots of theories to emerge. Things like a secret military experiment gone.
Carter Roy
Wrong, a UFO encounter, or a yeti.

Attack were floated for years. Even now, more than six decades later.
Carter Roy
We'Re still not sure what really happened.
Narrator
On that snowy peak. But one thing seems clear. It was anything but natural. Welcome to the story of Dyatlof Pass. People's lives are like a story. There's a beginning, a middle, and an end. But you don't always know which part you're on. Sometimes the final chapter arrives far too soon, and we don't always get to know the real ending. I'm Carter Roy, and this is Murder.

Narrator
Every theory feels like a possibility.
Carter Roy
Today, I'm discussing the Dyatlov Pass incident.
Narrator
One of Russia's most enduring mysteries and a story that's never sat quite right with me. In 1959, nine young hikers died under very strange circumstances in the northern mountains of Soviet Russia.
Carter Roy
Their tent was found torn open from the inside. Their bodies lay scattered across the snow. Some were barefoot, some were half dressed, and some had sustained injuries so severe they defied explanation. Investigators found no sign of struggle, no footprints but their own. For decades, no one knew what drove them out into the night or what truly killed them.
Narrator
That is, until 2019, when the answers finally felt within reach. All that and more coming up.

Carter Roy
On January 23, 1959, 23 year old.
Narrator
Igor Dyatlov packed his bags and lashed his skis together. He had a big day ahead of him.
Carter Roy
Igor was a quiet but magnetic engineering.
Narrator
Student at the Soviet Union's Ural Polytechnic Institute, or upi, but his true passion was the great outdoors.
Carter Roy
As a member of the school's hiking club, Igor was famous for his technical skills and and for the way people instinctively followed his lead.
Narrator
That day he and eight other students were getting ready for an expedition. But this wasn't just another trip for Igor. It was a test, a trial that.
Carter Roy
Would cement his reputation as one of.
Narrator
The best young mountaineers in the country.
Carter Roy
Over the next 16 days he Igor would lead his team across 190 miles.
Narrator
Of mountainous terrain in an attempt to.
Carter Roy
Reach the peak of Mount Otortin.
Narrator
If everything went as planned, they'd return.
Carter Roy
Home with the highest hiking certification in.
Narrator
The Soviet Union, grade 3.
Carter Roy
The people Igor had chosen to go.
Narrator
With him were strong, capable and very smart. 26 year old Alexander Kolevatov studied nuclear.
Carter Roy
Physics, 21 year old Yuri Doronshenko focused.
Narrator
On radio engineering and 23 year old Nikolai Thibaubrino had graduated with a civil construction degree. Georgi Krivonischenko, a 23 year old hydraulics and construction student, also joined them. Georgi was the joker of the group.
Carter Roy
And insisted on bringing his mandolin and.
Narrator
Which is like a small guitar to keep spirits high.
Carter Roy
There were only two women, 22 year old Zina Kolmogorova and 20 year old Ludja Dubinina.
Narrator
Zina was another radio engineering student and she was tasked with keeping a diary of their journey.
Carter Roy
Meanwhile, Luda studied construction economics, a field.
Narrator
That combines engineering, management and finance. Ludo was known for her endurance on long hikes. Once she'd been accidentally shot in the.
Carter Roy
Leg during a hunting trip. Then she joked her way along her.
Narrator
50 mile rescue trip through Siberia's mountains.
Carter Roy
The final two members were 23 year old Rustim Slobodin, who'd already graduated with a mechanical engineering degree, and 21 year.
Narrator
Old Yuri Yudin, who was studying economics.
Carter Roy
Yuri was probably the weakest link.
Narrator
He suffered from rheumatism, heart issues and had bad knees.
Carter Roy
Despite all that, he found freedom in hiking and swore he would be able.
Narrator
To make it through the trip. Once everyone was ready to go, the.
Carter Roy
Group of nine students made their way from their dorms to the local train.
Narrator
Station in the city of Sverdlovsky. When they got on board, they noticed one unfamiliar face among them.
Carter Roy
A last minute addition. Sasha Zolotagriov was 37 years old, had gold teeth and was covered in tattoos.
Narrator
A hiking instructor and World War II.
Carter Roy
Veteran, he bore the weight of experience.
Narrator
In his weathered features. If his age or his looks concerned the rest of the hikers, they didn't show it. Igor knew what he was doing.
Carter Roy
If he was fine with Sasha coming.
Narrator
They knew he'd make a good addition. Besides, you didn't need to be a student to go on the expedition.
Carter Roy
The hiking certification was given out by.
Narrator
The government, not the university, so Sasha could lend some valuable experience. The next day, in the early morning hours of January 24, 1959, they all disembarked in Serov, a grim industrial town buried in frost and smoke.
Carter Roy
They'd already been traveling for nearly 11.
Narrator
Hours, and they still had a long layover before their next train north. The hikers were desperate to get some rest. They'd planned to just nap in the.
Carter Roy
Train station, but the staff told them.
Narrator
It was against the rules. So the group set out in search of shelter.
Carter Roy
Eventually, they struck a deal with a nearby elementary school. They could sleep in a classroom that morning in exchange for giving a talk.
Narrator
To the students later that day. The kids ended up loving them.
Carter Roy
The group spoke about their upcoming adventure and sang songs. They even promised to stop by on their way home to tell the students.
Narrator
All about their journey. When it was Time to catch their train.
Carter Roy
The children poured out of the schoolhouse.
Narrator
To wave goodbye as the 10 hikers walked back to the station. That evening they boarded the 6:30 train bound for Evedell, a remote mining town. They arrived about five hours later and spent the night huddled in the station. The next morning, January 25th, they packed.
Carter Roy
Up, ate what they could and boarded their last train to the settlement of Vize.
Narrator
In every Siberian town, Igor made a.
Carter Roy
Point to visit the forest workers since.
Narrator
They knew the land the best.
Carter Roy
In Vize, that man was 53 year old Ivan Rempel. Rempel warned Igor and the others that.
Narrator
The winter winds beyond the ridge were deadly. The kind that could lift a person off their feet and hurl them into a ravine. Igor just smiled. This was what they'd come for, a challenge.
Carter Roy
He thanked Rempel, copied one of his.
Narrator
Detailed maps and turned to his friends. They were ready, but not all of them were doing well.
Carter Roy
Yuri Yudin's old pains had returned.
Narrator
His back throbbed with every step and.
Carter Roy
A familiar stiffness crept down his legs.
Narrator
He tried to hide it, but Ygor could see the pain on his face.
Carter Roy
That afternoon, they all piled into the open bed of a truck bound for a logging camp called sector 41.
Narrator
This would be their final stop before beginning their hike. It was a brutal three hour ride through freezing wind and rutted roads. Every jolt of the tire sent a knife of pain through Yudin's spine.
Carter Roy
By the time they arrived, he knew the truth.
Narrator
He couldn't go any further.
Carter Roy
On January 28, 1959, Yuri Yudin said.
Narrator
Goodbye to his friends.
Carter Roy
The group helped him load his pack.
Narrator
For the long trip home.
Carter Roy
He watched as they skied away into the white expanse, nine figures shrinking into the snow.
Narrator
He was the last person who would ever see them alive. From there, the only witnesses were the hikers themselves, their cameras and their diary. The entries from those first few days of the journey paint a picture of camaraderie, exhaustion and cold. They joked about who got to sleep.
Carter Roy
Closest to the stove and talked about.
Narrator
How often they had to stop to scrape ice from their boots and skis.
Carter Roy
For two days they followed a hunting.
Narrator
Trail cut through the forest by the Mansee, the indigenous people of the Urals. But on the third day, the weather turned. The wind roared through the trees, snow fell in sheets and visibility dropped to almost zero. The hikers argued, doubled back and searched for better ground.
Carter Roy
As night fell, they realized all they could do was set up camp, share.
Narrator
A warm meal and plan to regroup in the morning. On January 31, eight days after they.
Carter Roy
Left Sverdlovsk, they began climbing toward the.
Narrator
Base of Ortortin Mountain, known as Dead Mountain in the Manses native language. The ascent was steep and the snow was heavy.
Carter Roy
To move faster, Igor implemented a system.
Narrator
He called path treading. Each hiker took turns walking ahead to stamp down the snow for five minutes.
Carter Roy
Then fell back to rest as another.
Narrator
Person took their place. Still, it was slow going. By late afternoon, they descended into a.
Carter Roy
Valley where where the trees thinned and the wind softened.
Narrator
They built a fire from damp fir.
Carter Roy
Branches and ate dinner inside their tent.
Narrator
Ygor wrote in the diary that it.
Carter Roy
Was hard to imagine such a cozy place anywhere. The next morning, February 1st, they began.
Narrator
Building a labaz, which is a storage cache for food and supplies they'd collect on their way back.
Carter Roy
This meant they could climb the summit.
Narrator
Without any unnecessary weight in their packs. The hikers left behind spare boots, extra.
Carter Roy
Skis, a first aid kit, and Georgie's beloved mandolin.
Narrator
The last photos of the group show.
Carter Roy
Them skiing single file in a blinding.
Narrator
White snowy haze toward the unknown. As the light faded, they set up.
Carter Roy
Camp on an open slope, an east facing stretch of snow that would catch the morning sun.
Narrator
They pitched their tent, cooked a final.
Carter Roy
Meal, and settled in for the night.
Narrator
Outside, the temperature plunged below zero. The wind screamed across the mountainside.
Carter Roy
Igor Dyatlov and his team knew the.
Narrator
Weather conditions would make their journey even more dangerous, but they were confident in their abilities. Deep down, they knew that they could.
Carter Roy
Overcome any challenge, make their climb and.

Narrator
On the afternoon of February 1, 1959.
Carter Roy
23 year old Igor Dyatlov and eight other hikers set up camp on a.
Narrator
Snowy open slope in the Ural Mountains.
Carter Roy
They planned to summit Otorten Mountain, then return to the Ural Polytechnic Institute on.
Narrator
February 13, where they would earn their grade three hiking certification, the highest in the Soviet Union. But by February 16, three days after.
Carter Roy
They were supposed to return home, no.
Narrator
One had heard from them. Igor's sister, 21 year old Rufina, was one of the first people to sound the alarm. She knew in her gut that something had gone wrong. She'd already tried to convince the faculty.
Carter Roy
At UPI to send out a search.
Narrator
Party, but they brushed her off.
Carter Roy
They told her that delays happen all the time and that Igor could have decided to extend the trip.
Narrator
Rufina insisted that her brother was an.
Carter Roy
Expert hiker and knew how important it was to communicate any changes. If he'd adjusted their plans, someone in their group would have hiked back to civilization to send a letter or a telegram. The next day, after more pleading from Rufina, the university finally sent a telegram.
Narrator
To Vige, the last known settlement before the mountains.
Carter Roy
The reply from Vijay arrived at the.
Narrator
University on February 18. It read, the Dyatlov group did not return. Now Rufina wasn't the only one who was worried. Two days later, on February 20, 1959, the university launched a formal search. Helicopters took off from Sverdlask.
Carter Roy
With volunteers and hiking experts, they flew north toward the Urals, scanning ridges and slopes along what they assumed to be the group's trail.
Narrator
But days passed with no sign of the hikers. They expanded the search to include the.
Carter Roy
Local Mansi people who knew the region best. The Manses were led by tribesman Stepan Kurikov. With their help, the team had their first breakthrough.
Narrator
On February 25th, Boris Slubstoff, a 22 year old member of the university hiking club, spotted ski Tracks in the distance. He and the others trudged through the.
Carter Roy
Snow, following the tracks uphill. That led them to a tent, half buried and collapsed.
Narrator
It clearly belonged to the hikers.
Carter Roy
Inside, everything looked normal. Food was laid out, clothing was folded in corners, and diaries were stacked and organized. At first glance, it seemed like the group had just left a search for firewood or relieved themselves in the snow.
Narrator
But a closer look told a different, scarier story. The backside of the canvas had been.
Carter Roy
Slashed a few times and ultimately sliced open. From the inside, it was obvious the students hadn't calmly left the tent. They'd run away from it.
Narrator
The next day, February 26, more volunteers arrived to help search.
Carter Roy
Approximately 20 yards away from the tent, they found nine sets of preserved footprints.
Narrator
One for each of the hikers.
Carter Roy
They extended nearly half a mile toward.
Narrator
The valley before eventually disappearing.
Carter Roy
Strangely enough, the tracks didn't look like they were made by boots, but bare feet, which meant the hikers had exited the tent without shoes and stepped onto the freezing snow.
Narrator
It was bizarre.
Carter Roy
And that afternoon, another search party discovered.
Narrator
Something even more disturbing.
Carter Roy
There was a spot beneath a cedar.
Narrator
Tree that looked kind of off.
Carter Roy
The branches were charred, and there were.
Narrator
Traces of a small fire pit. It was haphazard and had clearly been made in a bind.
Carter Roy
Just north of the pit, a volunteer.
Narrator
Spotted something sticking out of the snow. When they approached it, they realized it was a human knee. Eventually, the volunteers uncovered two male bodies. As expected, they weren't wearing shoes, but.
Carter Roy
They also weren't wearing jackets or pants. Whatever they had run from had come on fast. One man was face down, his arms tucked beneath his head, almost like a pillow. The other was face up on his back.
Narrator
His eyes and mouth had been gouged, probably by a scavenging bird. Despite the injuries to his face, the hiker was still recognizable as Georgie Krivonischenko. The body next to him was identified as Yuri Doroshenko. The first two hikers had officially been found, but there were seven more to go.
Carter Roy
The searchers moved farther away from Yuri and Georgi, and before long, they came.
Narrator
Upon Igor Dyatlov, his frozen hands clutching a birch tree, as though he'd been fighting against the storm.
Carter Roy
Nearby, they discovered Zina Kolmogorova. She was on her right side, face.
Narrator
Down in the snow, her face dark with dried blood.
Carter Roy
Like the others, she wore no shoes, though she still had on a hat.
Narrator
Ski jacket and ski pants. Several days later, between where they'd found.
Carter Roy
Igor and Zeena, searchers discovered the body of Rustem Slobodin.
Narrator
Rustem was more clothed than the others, wearing a sweater, ski pants, a hat and several pairs of socks. His right leg had frozen beneath him, his right fist pulled to his chest.
Carter Roy
He looked like he'd been fighting and crawling in the direction of the tent. A giant bruise darkened the front of his skull, suggesting he'd sustained a powerful.
Narrator
Blow of some kind. The discoveries led to early theories about what had happened. Perhaps a blizzard forced the hikers from the tent, or maybe they were swept away by an avalanche.
Carter Roy
But the questions remained.
Narrator
If wind or snow drove them out, how was the tent still there?
Carter Roy
Why were their supplies left untouched? Why were so many of them shoeless? And why did the victims look injured?
Narrator
Unfortunately, the autopsies didn't shed much light on the tragedy.
Carter Roy
The results came in the first week of March. The coroner ruled that Igor, Zina, Yuri, Giorgi and Rustem had all died of hypothermia. But they also had external and internal.
Narrator
Injuries, suggesting something more violent had taken place. It was confusing, but investigators thought the.
Carter Roy
Other four hikers might be the key.
Narrator
To finding the answer. The search continued throughout March and April. It was slow going. But then, on May 3, Stepan Kurakov, the Mansi tribesman, came across some unusual looking branches hundreds of yards away from where the first five bodies had been found. The branches looked like they'd been cut with a knife. And about six yards away, there was a disturbed patch of snow. The crew started digging, and before long they discovered a pile of fabric. An inside out gray vest, a pair.
Carter Roy
Of knitted pants, a brown sweater, one trouser leg and a long bandage were all bundled together.
Narrator
The volunteers dug around expecting to find bodies.
Carter Roy
Instead, they only found more clothing.
Narrator
The rest of the trousers and half.
Carter Roy
Of a woman's sweater.
Narrator
The clothes definitely belonged to the Dyatloff team. Fellow students recognized them, and they were later compared to photos from the group's cameras.
Carter Roy
But where were the hikers themselves? The searchers spent several more days digging.
Narrator
Until suddenly a shovel hit something solid. The first body they found was nearly unrecognizable from watching. Water and snow induced decomposition. Nearby, there were three more bodies. The only one they could immediately identify was Luda, the construction economics student who is known for her strength and positive attitude.
Carter Roy
She still wore her hat, two sweaters, pants and two pairs of socks, but.
Narrator
Just on one foot. The other was wrapped in a torn sweater. Luda's face was battered and her mouth was stained dark red. A closer look revealed something truly disturbing. Luda's tongue was missing.
Carter Roy
The other two bodies were partially embracing Luda, like they'd all been huddling together for warmth.
Narrator
Unfortunately, they were too ravaged to identify at that point. On May 8, the bodies were taken.
Carter Roy
To Evdell, the town at the foot.
Narrator
Of the Ural Mountains. The medical examiner identified the first body.
Carter Roy
As Alexander Kolevatov, the nuclear physics student. He had died of hypothermia.
Narrator
The two men who had wrapped themselves.
Carter Roy
Around Luda were Nikolay Thibaubrino, the civil.
Narrator
Construction graduate, and Sasha Zolotagriov, the late addition to the group. Luda, Nikolay and Sasha had all suffered incredibly violent injuries, so their causes of death weren't as clear cut.
Carter Roy
In addition to her missing tongue, Luda's rib cage was shattered and her heart had ruptured.
Narrator
Sasha's ribs were crushed inward and Nicolet's skull was fractured.
Carter Roy
It was clear that these injuries weren't.
Narrator
Caused by cold or exposure.
Carter Roy
The medical examiner determined that some sort of large violent force had caused the damage while the victims were alive, and that those injuries were what ultimately killed them. But the source of that injuries, violent.
Narrator
Force, well, that was still a mystery. In the days that followed.
Carter Roy
Lead investigator Lev Ivanov studied the evidence with growing disbelief. The tent had been slashed open from the inside. Nine sets of mostly bare footprints trailed into the darkness. Supplies, boots and clothing were left behind. Fires had been lit, but quickly extinguished. The hikers fled into minus 30 degrees.
Narrator
Celsius temperatures, which is about minus 22 Fahrenheit. There was no sign of an intruder.
Carter Roy
No known avalanche, and no physical struggle. By mid May 1959, about three months.
Narrator
After the hikers disappeared appeared. Their cause of death was announced as.
Carter Roy
An insurmountable force of nature. Rumors spread quickly through Sverdlovsk. Families whispered about government cover ups. Soldiers hinted that strange lights were seen.
Narrator
In the sky that night. Others claimed the hikers had stumbled onto a secret weapons test.
Carter Roy
But ultimately the case file was sealed. The mountains were closed to visitors, and.
Narrator
The answers to the mystery remained buried too deep to dig out.

Narrator
In February 1959, nine hikers died in the Ural Mountains of the Soviet Union.
Carter Roy
According to the medical examiner, six had.
Narrator
Died of hypothermia and three from violent injuries.
Carter Roy
The Soviet government ruled that the last three deaths were the result of an.
Narrator
Unknown force of nature, then closed the investigation. But that didn't mean the story was over.
Carter Roy
The victim's friends and family were left with a lot of questions. And the most important one was also the most puzzling. What had caused these experienced hikers to leave their tent in the first place? An attack by members of the Mansi tribe was briefly floated, but the Mansi were a peaceful people and incredibly helpful.
Narrator
In the search for the missing students. It didn't make sense that they would target them. Alexei Krivonishenko, Georgi's father, had a different, more supernatural theory.
Carter Roy
He first heard about it from two.
Narrator
Other hikers who had recently made their own expedition into the northern Urals.
Carter Roy
On the night of February 1st, the same night Georgi and his companions presumably died, the hikers witnessed an extraordinary light.
Narrator
In the sky over the Ural Mountains.
Carter Roy
They said the glow was so bright they had to shield their eyes. And they weren't the only people who.
Narrator
Saw the mysterious light. Other hikers who'd been in the Urals between early and mid February reported seeing the same thing. These accounts caught the attention of of.
Carter Roy
Investigators at the Evedale prosecutor's office, who soon began calling in witnesses from across the region. One by one they spoke of strange glowing objects, most often described as slow moving orbs pulsing in the night sky. Were they UFOs?
Narrator
Soviet missile tests gone awry? No one knew for sure and no one could agree. Most witnesses said they saw the lights on February 17, not on the 1st like those two hikers had claimed.
Carter Roy
Even then, the sheer number and consistency.
Narrator
Of the accounts made the theory hard to ignore. It seemed like whatever had happened in the sky had something to do with the Dyatlov group's deaths.
Carter Roy
And soon the authorities got even more.
Narrator
Evidence that seemed to prove it.
Carter Roy
In mid March, about 20 days after the first hikers were found, investigators developed.
Narrator
The rolls of film recovered from the hikers cameras. Most of them didn't offer much information but the final image from Georgie's camera shocked them.
Carter Roy
Picture was blurry, but it appeared to.
Narrator
Show a glowing, indistinct light source dominating one side of the frame.
Carter Roy
To believers, this was proof that Georgi must have photographed the orb so many others had reported seeing.
Narrator
Unfortunately, later examination of the photo told a different story. The round shape was nothing more than a lens flare. The blurring was consistent with an accidental exposure, possibly taken when someone had mishandled the camera in the dark.
Carter Roy
As the orb theory began to lose credibility, the focus shifted to a different.
Narrator
More grounded radiation poisoning. After all, this took place during the height of the Cold War, the time.
Carter Roy
When the Soviet Union was competing with.
Narrator
The United States for nuclear supremacy. The Ural Mountains were vast and remote. Seemed like a pretty good place to conduct top secret military experiments. That led some people to wonder if.
Carter Roy
Igor's group had been the victims of a classified Soviet weapons test that ended in disaster.
Narrator
Maybe that would explain their panic and intense injuries. It was terrifying, but possible.
Carter Roy
Especially because when the hiker's clothing was.
Narrator
Tested, several garments showed elevated levels of radiation.
Carter Roy
In his report, Sverdlovsk, chief municipal radiologist, wrote that the level of contamination exceeded standards for people working with radioactive substances.
Narrator
It was the kind of result that invited speculation and the kind of rumor that Soviet authorities did not want circulating. And so, just as the investigation seemed on the verge of a breakthrough, everything stopped.
Carter Roy
On May 28, 1959, one day before the final radiation reports were supposed to be released, Lev Ivanov, the lead investigator on the Dyatlov case, was told to.
Narrator
Stop the inquiry immediately. No further tests, no new reports.
Carter Roy
For the next 51 years.
Narrator
There was no movement in the case.
Carter Roy
But even then, the mystery of Dyatlov Pass lingered. And there were still plenty of people who were determined to uncover the truth.
Narrator
In 2010, American author and documentary filmmaker Donny Eichar learned about the Dyatlov tragedy and became obsessed with cracking the case.
Carter Roy
Luckily for him, a lot had changed.
Narrator
Since those nine hikers perished.
Carter Roy
In 1991, the Soviet Union collapsed and.
Narrator
Russia took its place.
Carter Roy
The new government was less secretive and.
Narrator
More open to outside investigation. That's probably why Donnie was able to get his hands on the original radiation test reports.
Carter Roy
He sent those to Dr. Christopher Strauss, an associate professor of radiology at the.
Narrator
University of Chicago Medical Center.
Carter Roy
Donnie was eager to learn if the radiation poisoning theory held any water all these years later. And according to Dr. Strauss, it didn't. He said the levels of beta particle.
Narrator
Decay on the hiker's clothes were completely normal.
Carter Roy
In fact, those Readings would have had.
Narrator
To be at least 50 times higher to be considered unusual, let alone harmful. It's not clear if the standards in.
Carter Roy
1959 were different or if the Soviet.
Narrator
Radiologist had made a mistake.
Carter Roy
But Dr. Strauss also had an explanation.
Narrator
For why there were even traces of radiation on the hikers in the first place.
Carter Roy
He said the contamination probably came from environmental fallout. That winter in 1959, nuclear tests were conducted on the islands of novaya Zemlya, roughly 850 miles north of where the.
Narrator
Hikers met their ends.
Carter Roy
Through the air, the snow, and the water cycle, those particles could have drifted south, settling invisibly across the Urals, but.
Narrator
Not in levels dangerous enough to harm someone. So with the radiation theory debunked, Donnie Eichar continued his investigation.
Carter Roy
It would take him across the United States, out to Russia, and ultimately to the very same slope on which the.
Narrator
Hiker'S tent was found 53 years earlier.
Carter Roy
Along the way, he was able to.
Narrator
Rule out plenty of other theories that had popped up over the years.
Carter Roy
One idea was that the hikers might.
Narrator
Have suffered carbon monoxide poisoning inside the tent, that a poorly ventilated stove had filled the air with toxic fumes.
Carter Roy
But Donnie discovered that the group had.
Narrator
Not started a fire that night.
Carter Roy
Their portable stove hadn't been used and still sat unassembled among their supplies.
Narrator
Supplies in the tent. Plus there was no smoke damage, no soot, no evidence of heat.
Carter Roy
There were also rumors of a wild animal attack.
Narrator
Some suggested a bear, a wolf, or even the mythical yeti had torn into.
Carter Roy
The tent, driving the hikers out in terror. But there were no signs that a.
Narrator
Struggle had taken place.
Carter Roy
The tent had been sliced open from the inside, not the exterior. And the bodies showed no bite marks or claw wounds. The only possible animal interaction was the.
Narrator
Removal of Luda's tongue, which investigators assumed was eaten by rodents after she died. The one theory that seemed the most plausible was also the least exciting.
Carter Roy
The hikers may simply have been victims of an avalanche. They pitched their tent high on a slope, and so maybe they'd heard the.
Narrator
Ominous groan of shifting snow above them and fled into the freezing dark, trying to outrun it.
Carter Roy
In 2012, Vladimir Borkunzov, an aviation engineer, investigator, and one of the foremost experts.
Narrator
On the Dyatlov case, decided to test the theory.
Carter Roy
Using GPS data, he calculated the mountain's slope with. With precision.
Narrator
What he found left little room for doubt.
Carter Roy
The runout angle, otherwise known as the distance snow would travel once released, was incredibly flat. Because of this, an avalanche simply couldn't move far enough or fast enough to reach the camp. Plus, while the tent was partially collapsed, it was still standing, and its contents were undisturbed.
Narrator
No avalanche could have passed over it without flattening everything in its path. Even back in 1959, investigators had dismissed the idea entirely.
Carter Roy
There were no telltale fractures, no debris fields, no displaced snow. And in the years since, Donnie could find no record of an avalanche ever.
Narrator
Having been documented or on that mountain slope.
Carter Roy
Running out of options, Donnie tried something no one had been able to do.
Narrator
So get an interview with Yuri Yudin.
Carter Roy
Now in his mid-70s, Yudin had been.
Narrator
The last person to see the Dyatlov.
Carter Roy
Group alive before he left the hike.
Narrator
Because of his chronic pain, tracking Yudin down wasn't easy.
Carter Roy
At some point, he'd become a recluse. Whether he was overcome with survivor's guilt.
Narrator
Annoyed by all the questions about the.
Carter Roy
Hikers, or simply grown older, Yudin made.
Narrator
It clear he didn't want to be found.
Carter Roy
But Donnie was determined. He spent years trying to get in touch with Yuri, and eventually he succeeded. In February 2012, 53 years after the.
Narrator
Dyatlov group went missing, Donnie met with Yuri in Russia for an interview. After covering the basics, Donnie asked Yuri the question everyone had wanted to know. What did he think happened to his friends? Yuri said he didn't think they died in an accident or by natural causes. To him, the explanation was far darker.
Carter Roy
Yuri believed that maybe the group had crossed into a restricted area and that.
Narrator
Armed men had found them. He thought they saw something they shouldn't have and were killed because of it. In Yuri's mind, the scene on the mountain had been staged. His friends were coerced, forced to walk.
Carter Roy
Into the forest half dressed and ordered to destroy their own clothing to create.
Narrator
Confusion, then abandoned to die in the cold. Yuri's main piece of evidence was Luda's missing tongue. Investigators had always assumed it had either decomposed or had been eaten by animals. But Yuri didn't buy that.
Carter Roy
He thought that strong willed, outspoken Luda.
Narrator
Had been singled out. She had talked too much and been punished for it.
Carter Roy
There were other small discrepancies that fueled Yuri's theory. Luda's beloved good luck charm, the tiny.
Narrator
Stuffed hedgehog she always carried, had not been found with her.
Carter Roy
The hiker's chocolate rations were also missing, with no wrappers left behind. To Yuri, these were traces of human.
Narrator
Interference, signs of looting or concealment. Someone had taken these things, thinking no one would notice.
Carter Roy
Donnie listened, but he wasn't convinced. After the interview, he looked Into Yuri's.
Narrator
Claims and confirmed what he'd suspected all along. Yuri was almost certainly wrong. The hedgehog toy had been logged as.
Carter Roy
Evidence, and Luda's tongue wasn't cut out.
Narrator
It was missing due to natural decomposition. Her body had been laying in the partially melted snow for weeks. During that time, water and microorganisms had eroded the soft tissue. Even the missing chocolate had a mundane answer.
Carter Roy
When Donnie interviewed searchers from the original 1959 recovery, two of them admitted that they'd found the hiker's chocolate, eaten it.
Narrator
And pocketed the wrappers as they continued on their mission.
Carter Roy
To Donnie, it felt like every theory.
Narrator
Fell apart as soon as it was examined. By 2013, after traveling to Russia, interviewing.
Carter Roy
Yuri Yudin, and talking to countless experts.
Narrator
He was almost ready to give up. Then his research led him toward a.
Carter Roy
Stranger but even more realistic theory. A phenomenon called infrasound. Infrasound is the inverse of ultrasound and.
Narrator
Exists below the range of human hearing. But even though we can't hear it.
Carter Roy
We can feel it.
Narrator
These low frequency waves can occur naturally.
Carter Roy
In the world as byproducts of earthquakes, landslides, and storms.
Narrator
Man made infrasound is also possible. It can happen via ventilation systems, wind farms and machinery.
Carter Roy
And at certain intensities.
Narrator
Infrasound can wreak havoc on the human.
Carter Roy
Body, producing nausea, disorientation, panic, and in.
Narrator
Extreme cases, psychological collapse.
Carter Roy
During his research, Donnie learned that some governments had experimented with infrasound in the past.
Narrator
Nazi Germany had once used low frequency sound to manipulate crowds at political rallies and had experimented with it as a form of weaponized torture.
Carter Roy
Donnie wondered if the Dyatlov hikers were.
Narrator
Victims of an infrasound attack, either in.
Carter Roy
The form of a test by the Soviet government or in a naturally occurring.
Narrator
Scenario due to the wind conditions on the mountain. He reached out to Dr. Alfred J. Bedard, Jr. He was a senior scientist and infrasonic.
Carter Roy
Specialist at the national oceanic and Atmospheric.
Narrator
Administration in Boulder, Colorado, and had spent decades studying how these frequencies behave. If anyone could determine whether infrasound had played a role in the hikers deaths, it was him.
Carter Roy
Dr. Bedard confirmed that under the right conditions, an infrasound incident could have occurred on the mountain. Then he asked Donnie if he had ever heard of something called a Karman vortex. Dr. Bedard explained that a karman vortex.
Narrator
Is a rare meteorological pattern. It forms when wind passes a blunt object of a particular shape and speed.
Carter Roy
Creating alternating spirals of air.
Narrator
These spirals are essentially miniature tornadoes that roll away in two Parallel lines.
Carter Roy
They can create strong vibrations in the air, and sometimes they generate infrasound.
Narrator
As they studied Donnie's photographs of the.
Carter Roy
Campsite, Dr. Bedard noticed something striking. The mountain's summit had a perfectly symmetrical rounded dome, exactly the kind of shape that could produce a Karman vortex under.
Narrator
The right wind conditions. The tent's location just below that dome.
Carter Roy
Placed the hikers directly in the path.
Narrator
Of those invisible vortices. In other words, it was a perfect setup for disaster. Donnie was stunned.
Carter Roy
Bedard was telling him that his infrasound theory wasn't just possible, but probable. Together, they imagined what the hikers might.
Narrator
Have experienced inside their tent that night. There would have been a sudden gust of wind, then a low thrum humming vibration in the ground.
Carter Roy
Suddenly, a roar as loud as a.
Narrator
Freight train would have passed from west to east. The canvas walls of the tents would.
Carter Roy
Have started to tremble, and the hikers.
Narrator
Chests would have been vibrating with sub audible pressure.
Carter Roy
Another roar from the north would have.
Narrator
Increased their growing panic.
Carter Roy
Their breath would have tightened, their hearts.
Narrator
Would have been pounded, and the terror.
Carter Roy
Would have started to override reason. Dr. Bedard believed that this could explain everything. The panic, the confusion, the frantic decision to cut their way out into the cold. The hikers weren't running from an avalanche or an intruder. They were fleeing from sound itself, from.
Narrator
The deep, invisible pressure waves of the mountain wind.
Carter Roy
For more than 60 years, the story.
Narrator
Of the Dyatlov Pass has haunted those who heard it. Nine experienced hikers vanished into a snowstorm, never to be heard from again.
Carter Roy
Families demanded answers. Investigators chased leads that faded in into the cold.
Narrator
Over time, the case turned into more than a tragedy. It became a legend.
Carter Roy
Donnie Eicher and Dr. Bedard's infrasound theory offered a logical explanation that bridged science and circumstance. Unfortunately, experts are split on whether infrasound.
Narrator
Can actually cause this level of psychological distress.
Carter Roy
And the Russian government seemed to think it couldn't.
Narrator
In 2019, Russian officials reopened the investigation.
Carter Roy
And returned to an old theory that.
Narrator
A rare type of slab avalanche had forced the hikers out of their tent, prompting them to run out into the cold. This verdict, like all others, remains highly disputed.
Carter Roy
Most experts agree that the conditions weren't.
Narrator
Right for an avalanche. But as far as the Russian government is concerned, that's what happened. The truth is, we may never know the full story.
Carter Roy
There are still several details that we.
Narrator
Can'T explain, including the lights in the.
Carter Roy
Sky, the burnt tree, and the hiker's extensive injuries.
Narrator
But in our rush to try to.
Carter Roy
Understand can be easy to forget the.
Narrator
True damage that was caused that day. Nine young people lost their lives.
Carter Roy
They were brilliant students, accomplished professionals and adventurous spirits. They were all united by their love of the outdoors and their desire to prove themselves. And while we can never bring them.
Narrator
Back, we can know their journey ended the same way it began.
Carter Roy
Together.

This episode of Murder: True Crime Stories launches "Mystery Fridays" by delving into the infamous Dyatlov Pass Incident: the unsolved 1959 tragedy where nine experienced Soviet hikers perished under mysterious and chilling circumstances in the Ural Mountains. Host Carter Roy guides listeners beyond the grisly crime scene and through a maze of tangled theories, scientific investigations, and personal stories—ultimately exploring why the Dyatlov Pass still haunts the world’s imagination.
(05:35 – 13:02)
"He watched as they skied away into the white expanse, nine figures shrinking into the snow. He was the last person who would ever see them alive." – Narrator (13:02)
(18:00 – 31:02)
"The medical examiner determined that some sort of large, violent force had caused the damage while the victims were alive... but the source... well, that was still a mystery." – Carter Roy (29:21)
(31:02 – 46:38)
(46:43 – 53:17)
"Dr. Bedard believed that this could explain everything. The panic, the confusion, the frantic decision to cut their way out into the cold. The hikers weren't running from an avalanche or an intruder. They were fleeing from sound itself." – Carter Roy (51:14)
"Every theory feels like a possibility." — Carter Roy (03:16)
"The tent had been slashed open from the inside. Nine sets of mostly bare footprints trailed into the darkness." — Carter Roy (29:47)
"While we can never bring them back, we can know their journey ended the same way it began. Together." — Carter Roy (53:59)

Carter Roy’s narration is empathetic, methodical, and contemplative. He draws the listener into the historical era, the personalities of the victims, the emotional turmoil of their families, and the evolving nature of the investigation. “Haunted,” “chilling,” “tragic,” and “legend” are recurring moods—balanced by measured skepticism as new evidence and theories are weighed.
Despite decades of speculation, state secrecy, and renewed investigations, the Dyatlov Pass Incident remains one of the most enigmatic tragedies in true crime history. The episode leaves listeners appreciating not just the enduring mystery, but the remarkable individuals lost and the relentless human search for answers.
