The Grinning Man – When Witnesses Disappear

A tall figure with an impossible smile. But the real mystery isn't what they saw. It's what happened after. This investigation traces how witnesses vanish, reputations erode, and truth collapses into silence.

They saw a figure that should not exist – tall, impossibly grinning, watching from the periphery of roads and memory. But what followed the encounter often proved stranger than the entity itself. Media ridicule, official denial, and sometimes harassment by faceless men in black.

Was the real anomaly the witness, or the system that moved to silence them? This investigation traces where intimidation ends, and mythology begins.

The First Sightings

In the autumn of 1966, a particular strand of unease wove itself into the tapestry of the uncanny.

In Elizabeth, New Jersey, two teenage boys, James Yansidis and Martin Munov, walking home one October night, saw something beneath the New Jersey Turnpike that neither could explain – a towering man in reflective green, standing motionless. His face, they recounted, was hairless, noseless, unblinking, dominated by an impossibly wide grin, fixed like a painted threat. No words were exchanged; just the smile and the silent, watchful presence. The terrified boys fled.

Weeks later, on 2 November 1966, Woodrow Derenberger, a sewing machine salesman in West Virginia, was driving along Interstate 77. He reported being halted by an object like an ‘old kerosene lamp globe’ descending from the sky. From it emerged a tall man whose appearance seemed subtly off. Communicating telepathically, he introduced himself as ‘Cold’, or ‘Indrid Cold’. He smiled, apparently kindly, claimed to come in peace, and asked peculiar questions.

Only later, through investigators and time, did these distinct events fuse into a singular, more potent legend – The Grinning Man. They were not, initially, the same. This divergence might be the most important clue.

Two Encounters, One Legend

The original sighting beneath the New Jersey Turnpike remains one of the clearest depictions of the so-called Grinning Man.

Woodrow Derenberger’s original account of Indrid Cold included no monstrous smile. ‘Cold’, he first described, appeared “perfectly natural and normal as any human being,” with dark features and a metallic suit. He communicated telepathically but did not grin grotesquely.

That defining detail of the Grinning Man archetype was seemingly added later, shaped significantly by journalist John Keel.

The New Jersey entity, by contrast, was grotesque: seven feet tall, with “beady” eyes and an “ear-to-ear” grin. There was no telepathy, no introduction; just silent presence and raw fear.

Keel explicitly linked these encounters, suggesting they were one phenomenon. In Strange Creatures from Time and Space, he connected Cold to the New Jersey figure, naming both ‘The Grinning Man’.

“If Cold didn’t smile, and the figure in New Jersey didn’t speak, then who decided they were the same?”

This synthesis created a composite that arguably never existed in original testimony, merging Cold’s calm demeanour with the New Jersey figure’s horrific visage.

Whether this blending was deliberate narrative construction or unconscious recognition of perceived connections is debatable. The consequence was a powerful folkloric presence.

This folkloric process, collapsing distinct experiences, perhaps reveals more about era-specific anxieties and narrative contagion than about the entity itself. Crucially, it may have obscured the possibility of multiple, distinct phenomena being conflated, perhaps for clarity or strategic confusion.

Anatomy of the Uncanny

The Grinning Man’s appearance, as solidified through the New Jersey account, seems almost designed to induce maximum psychological distress. His form often occupies the ‘Uncanny Valley’, that disturbing space where the almost-human evokes revulsion rather than empathy.

The smile itself, the creature’s hallmark, is a profound perversion of a basic social signal. Where a normal smile conveys warmth, the Grinning Man’s suggests something predatory and knowing, an amusement at the witness’s fear. This fixed, silent rictus dislocates the familiar.

This corruption of human features serves two purposes…
Firstly, it creates immediate, visceral fear. Secondly, it makes the witness’s account inherently difficult to relay credibly. How does one describe something recognisably human yet qualitatively wrong, a smile that violates every expectation?

The psychological impact often extends beyond the encounter, with witnesses reporting persistent nightmares, sleep disturbances, and an altered sense of reality. One, decades later, suspected electromagnetic fields might cause such hallucinations. The experience’s bizarreness can create a feedback loop of doubt, making the witness vulnerable to invalidation.

What Happens After – Witness Destruction

What elevates the Grinning Man beyond urban legend is the pattern of what befalls witnesses.

Woodrow Derenberger’s case is instructive. A successful salesman, he was thrust into a media frenzy after publicising his Indrid Cold story. This attention came at great cost – Derenberger lost his job, his marriage dissolved, and he became increasingly isolated. A year later, John Keel found him “hiding behind drawn curtains,” overwhelmed.

This progression from anomalous encounter to personal collapse is not unique. In Point Pleasant, West Virginia, the epicentre of the 1966 to 1967 Mothman sightings involving a winged humanoid said to foretell disaster, a girl reportedly saw a large, grinning man in her bedroom.

Derenberger himself claimed repeated visits from Cold and ‘friends’, eventually recounting journeys to a planet named Lanulos. He died a pariah, his original account buried under incredible claims.

What Was Suppressed
Witness suppression rarely involves direct silencing. It’s slower, subtler – jobs lost, credibility stripped, lives unravelled.

The UFO research community has long reported the arrival of ‘Men in Black’ (MIB) following significant sightings. These figures, in dark suits, exhibiting odd behaviour, seem to specialise in witness intimidation. Their methods are often subtle, relying on unnerving prescience and psychological pressure.

Albert Bender, founder of the International Flying Saucer Bureau, claimed three such figures visited him in 1953, warning him to cease his research. He subsequently shut his organisation

John Keel reported extensive harassment during his own investigations, including surveillance, stolen evidence, and eerie visitations, some seeming deliberately tailored to destabilise him. Keel viewed MIBs not merely as government agents but as “demonic supernaturals” or “ultra-terrestrials.”

Witness destabilisation is rarely dramatic. More often, cumulative pressure from ridicule, institutional scepticism, social ostracisation, and internal doubt wears the witness down. A life ruined by such means becomes its own warning. This may be the most effective suppression: not silencing by force, but by facilitating an implosion of the witness’s life and credibility.

The Playbook of Intimidation

Tactics used against UFO witnesses often echoed known psychological warfare playbooks like COINTELPRO and Zersetzung.

Tactics reported by harassed witnesses resemble documented psychological warfare (psyops) programmes.

The FBI’s COINTELPRO (1950s-1970s) and the East German Stasi’s “Zersetzung” (disruption) programme both used sophisticated psychological destabilisation to neutralise perceived threats without overt violence.

“The goal isn’t silence. It’s implosion.”

COINTELPRO’s arsenal included surveillance, disinformation, and undermining targets’ relationships, reputations, and mental health. Zersetzung employed insidious gaslighting techniques like subtly rearranging a target’s home or making silent phone calls to induce paranoia.

Parallels with MIB tactics are striking.

Witnesses describe harassers with intimate knowledge of their lives, making unsettling calls, or appearing with ambiguous warnings. The harassment often has a surreal quality, making it hard to report credibly, much like the original Grinning Man encounters.

Consider the psychology – if a witness reports a bizarre entity, then equally strange individuals making threats, their overall credibility diminishes. The secondary harassment often mirrors the original encounter’s high strangeness, creating a self-reinforcing cycle of incredibility that isolates and neutralises the witness.

The purpose appears to be comprehensive destabilisation and discrediting.

Staged Encounters?

Beyond official silence or reactive dismissal, a more unsettling possibility emerges from the patterns of high strangeness and psychological impact – that some Grinning Man encounters, and perhaps the ensuing harassment, may not be organic phenomena at all, but deliberately staged events.

The entity’s appearance, as noted, seems almost perfectly calibrated for maximum psychological trauma while simultaneously ensuring the witness’s account will be dismissed as incredible by most, including authorities.

Historical precedent for such psychological operations exists. During the Cold War, Colonel Edward Lansdale reportedly used tactics in the Philippines like staging fake vampire attacks to terrorise Huk rebels, exploiting local superstitions. More recently, the Reagan administration authorised peacetime psyops to manipulate public perception.

If intelligence agencies staged Grinning Man encounters, objectives could include – terrorising witnesses into silence; discrediting their original observations; or creating such bizarre secondary accounts that the affair is dismissed as delusion.

Technology for convincing projections was limited in the 1960s, but even crude deceptions, properly deployed, can have profound effects. Operatives in costume are also plausible. The aim: not to win an argument, but to neutralise the witness through confusion, fear, and destroyed credibility.

The Predatory Smile – Archetype or Weapon?

Across cultures, the fixed grin appears in tales of malice and haunting. A universal warning signal in human psychology.

The Grinning Man’s smile is central to his unsettling power. Not warm or human, it is fixed, impossibly wide, and deeply disturbing, residing in the Uncanny Valley. A face subtly wrong in proportion or expression becomes a potent threat signal.

In nature, predators show teeth as warning. The smile, stripped of cultural sincerity, can revert to this primal signal. Whether this aspect was consciously designed (by human agents or other intelligence) or is an emergent archetype drawing on evolutionary responses, the effect is consistent – witnesses are disturbed, frightened, and their accounts dismissed due to this inherent strangeness.

Across cultures, the smiling predator recurs in folklore, the Pisadeira, the night hag, demons whose grins signify malice. The Grinning Man could be a modern mask for an old fear, the watcher behind the curtain whose presence signifies a boundary crossed.

Or perhaps not a mask, but an artefact, a trace of something crossing into our reality during moments of narrative rupture, when an experience becomes too strange to hold and collapses inward, leaving only the smile’s unsettling resonance.

Machinery of Silence

In many cases, the witness doesn’t just disappear from public record, they vanish from themselves.

The fate of Grinning Man witnesses often hinges less on what they saw than on what followed. Some were harassed; others undone by trauma, or the machinery of disbelief and ridicule.

Whether the primary suppressor is a clandestine agency, non-human intelligence, a potent archetype, or consensus reality’s self-correcting mechanism, remains unresolved. Each hypothesis carries its own suppression mode. If human agents, psyops discredit witnesses. If non-human, the psychological response can be self-suppressing. If a legend, modern folklore’s structure (media, ridicule, psychiatric framing) contains and propagates it.

The lesson is not merely that strange things are hidden, but that hiding is itself a significant cultural and psychological force, shaping which memories survive and which are marginalised.

What else have we forgotten because the witness didn’t survive the memory?
