Criminals/ Former inmates theory in Dyatlov Pass Incident

The Criminals/Former Inmates theory in the Dyatlov Pass Incident posits that the nine hikers who died in the Ural Mountains in February 1959 were attacked by escaped prisoners or former inmates, possibly ex-soldiers or officers wrongfully convicted under Stalin’s regime. This hypothesis emerged due to the mysterious and violent nature of the hikers’ deaths, combined with the historical context of the Soviet Union’s Gulag system and the remote Siberian setting.

 

Background of the Dyatlov Pass Incident

In January 1959, a group of nine experienced hikers from the Ural Polytechnical Institute, led by 23-year-old Igor Dyatlov, embarked on a skiing expedition to reach Otorten Mountain in the northern Ural Mountains. On the night of February 1–2, 1959, the group pitched their tent on the slope of Kholat Syakhl (meaning "Dead Mountain" in the local Mansi language). Something catastrophic occurred, causing the hikers to cut their tent from the inside and flee into the freezing night, poorly dressed and without shoes. Their bodies were later found scattered across the area, some with severe injuries, including chest fractures and skull trauma, and one missing her tongue and eyes. The official Soviet investigation concluded that the deaths were caused by a “compelling natural force,” but the lack of clarity fueled decades of speculation and alternative theories, including the Criminals/Former Inmates hypothesis.

 

The Criminals/Former Inmates Theory

The Criminals/Former Inmates theory suggests that the hikers encountered a group of escaped prisoners or former Gulag inmates living in the remote Siberian wilderness. These individuals, possibly ex-soldiers or officers convicted under Stalin’s infamous Article 58 (anti-Soviet activities), may have used their military training to survive in the harsh environment after escaping from nearby labor camps. According to the theory, the inmates, fearing discovery by the hikers, attacked and killed them to eliminate witnesses who could report their presence to authorities. The violent injuries, the chaotic scene, and the remote location are cited as supporting this scenario.

 

Historical Context Supporting the Theory

The Gulag System in Siberia:
In the 1950s, Siberia was a hub for the Soviet Union’s Gulag system, with numerous forced-labor camps housing political prisoners, criminals, and former soldiers. Many camps were located in the Ural region, including near Ivdel, close to the Dyatlov Pass.
After Stalin’s death in 1953, some prisoners were released, but others escaped or were left in limbo, particularly those convicted under Article 58 for “crimes against the state.” These individuals often faced societal stigma and had little incentive to return to Soviet society, potentially leading them to live off the land in remote areas.
Escaped prisoners were known to form small, survivalist groups, relying on their skills (especially if they were former military personnel) to evade capture.

Military and Survival Skills:
The theory suggests that former soldiers or officers, trained in combat and survival, could have been living in the wilderness for years. Their expertise could explain the precise and powerful injuries inflicted on some hikers, such as the chest fractures likened to car crash injuries, which coroner Boris Vozrozhdenny stated could not have been caused by human hands due to their force and lack of soft tissue damage.
The attackers’ familiarity with the terrain could also explain why no additional footprints (beyond the hikers’) were found, as they may have covered their tracks or used the harsh weather to their advantage.

Motive for Attack:
The theory posits that the inmates viewed the hikers as a threat. In the Soviet Union, citizens were often encouraged to report suspicious activity, and the hikers, as young, educated students, might have been perceived as likely to alert authorities if they encountered fugitives.
Killing the hikers would ensure the inmates’ continued freedom, especially in a region where recapture could mean harsh punishment or execution.

 

Evidence Supporting the Theory

Violent Injuries:
Some hikers sustained severe trauma, including Lyudmila Dubinina’s missing tongue and eyes, Nikolay Thibeaux-Brignolle’s fractured skull, and chest fractures in Dubinina and Semyon Zolotaryov. These injuries suggested a violent encounter, potentially with individuals capable of inflicting significant force.
The coroner’s report noted that the injuries were inconsistent with human-inflicted blows due to their extreme force, but proponents of the theory argue that trained ex-soldiers could have used weapons or techniques to cause such damage.

The Chaotic Scene:
The tent was cut open from the inside, suggesting the hikers fled in panic, possibly after hearing or seeing attackers. Footprints showed they ran in different directions, which could indicate an attempt to escape a coordinated assault.
The hikers’ failure to regroup or return to the tent might suggest they were being pursued or feared immediate danger.

Missing Evidence and Artifacts:
A tin can, possibly from condensed milk dated 1958, was found buried near a cedar tree close to the hikers’ bodies, suggesting recent human activity in the area. While it could belong to the hikers, it might also indicate the presence of others, such as fugitives scavenging supplies.
Some reports mention a military-style cloth or item that disappeared from evidence, potentially linked to former soldiers or inmates.

Soviet Secrecy:
The Soviet authorities’ suppression of case details, including classifying files until the 1970s and ordering investigators like Lev Ivanov to dismiss reports of “flying spheres,” fuels suspicion of a cover-up.
Evgeny Okishev, a deputy prosecutor, noted unusual interference from Moscow, including orders to shut down the investigation prematurely, which could suggest efforts to conceal a sensitive incident involving escaped prisoners.

 

Counterarguments and Challenges

Lack of Footprints or Direct Evidence:
Search parties found only the hikers’ footprints in the snow, with no evidence of additional tracks from attackers. Harsh weather could have erased tracks, but the absence of physical evidence weakens the theory.
No weapons, tools, or other signs of a struggle (e.g., blood or torn clothing from a fight) were documented at the scene.

Coroner’s Findings:
Coroner Boris Vozrozhdenny stated that the severe injuries (e.g., chest fractures) lacked soft tissue damage, which is atypical for human-inflicted blows, even by trained individuals. This led some to argue that a natural force, like an avalanche, was more likely.
The missing tongue and eyes in Lyudmila Dubinina could be attributed to natural processes, such as scavenging animals or decomposition, rather than deliberate mutilation.

Behavior of the Hikers:
The hikers fled without shoes or adequate clothing, which seems extreme for an encounter with humans. If attacked, they might have attempted to negotiate or fight back, especially since some were physically fit and trained in survival. Instead, their actions suggest a sudden, overwhelming panic.
The group’s diaries and photos show no signs of prior concern about being followed or encountering others, which might be expected if they had crossed paths with suspicious individuals earlier.

Alternative Explanations:
The slab avalanche theory, supported by Swiss researchers Alexander Puzrin and Johan Gaume in 2021, provides a scientific explanation for the injuries and chaotic scene. They argue a small slab avalanche could have crushed the tent, causing injuries and prompting the hikers to flee.
Katabatic winds, proposed by a 2019 Swedish-Russian expedition, suggest a violent windstorm disoriented the hikers, leading to their deaths from hypothermia and injuries.
Paradoxical undressing, a phenomenon where hypothermic individuals remove clothing due to feeling overheated, explains the state of undress, reducing the need to invoke attackers.

Logistical Challenges:
Escaped inmates surviving in the Ural wilderness during a harsh winter would face extreme difficulties, including finding food and shelter. The remote location of Kholat Syakhl, far from known Gulag camps, makes it less likely for fugitives to be present.
Coordinating an attack without leaving traces, especially in deep snow, would require exceptional skill and planning, which seems improbable for a group of desperate escapees.

 

Plausibility and Broader Context

The Criminals/Former Inmates theory is compelling because it aligns with the violent injuries and the Soviet Union’s secretive handling of the case, which fueled conspiracy theories. The Gulag system’s prevalence in Siberia and the possibility of escaped prisoners add historical plausibility. However, the lack of direct evidence, such as additional footprints or signs of a struggle, undermines the hypothesis. The severe injuries, while suggestive of violence, are better explained by natural phenomena like a slab avalanche, which accounts for the force and lack of soft tissue damage.

The theory also reflects the cultural and historical anxieties of the Soviet era, where fear of state surveillance, betrayal, and hidden enemies was pervasive. The idea of rogue ex-soldiers or prisoners attacking innocent students taps into these fears, making it a popular narrative in post-Soviet discussions when censorship eased. However, scientific advancements, such as the 2021 avalanche model, have shifted focus toward natural explanations, reducing the theory’s prominence among researchers.

 

Cultural Impact and Speculation

The Criminals/Former Inmates theory has contributed to the Dyatlov Pass Incident’s status as a cultural phenomenon, inspiring books, documentaries, and fictional works like the 2013 film Devil’s Pass, which explores a conspiracy-laden version of the event. Russian investigative journalist Svetlana Oss suggested a variation involving local hunters under the influence of psychedelic mushrooms, highlighting how human-attack theories proliferate due to the case’s unanswered questions. The theory persists in public imagination because it offers a human antagonist, making the tragedy feel more tangible than abstract natural forces.
