The open questions
Which conspiracy theories are still unproven?
Some claims sit in the middle. 403 of our 978 case files carry no verdict: there is no firm evidence either way, so we leave them open rather than force one. Being honest about what is unresolved is the point. Here are the most-read, each with the case laid out both ways.
Phoenix Lights
On the night of March 13, 1997, thousands of people across Arizona watched two different things: a huge, silent V-shaped formation of lights that crossed the state around 8 p.m., and a row of stationary lights over Phoenix two hours later. The military solved the second event: confirmed flares from a training exercise. The first has never been officially explained at all.
Read the case file →Ed and Lorraine Warren
Ed and Lorraine Warren are the most famous paranormal investigators in American popular culture: a self-described demonologist and a self-described clairvoyant medium who spent half a century investigating reported hauntings and turning the most dramatic into books, lectures, and eventually the Conjuring film universe. Their real biography is well documented. They met in Bridgeport, Connecticut in the 1940s, founded the New England Society for Psychic Research in 1952, assembled an Occult Museum of objects they said were cursed (the Annabelle doll among them), and lent their names to Amityville, the Perron family in Rhode Island, the Enfield poltergeist in London, and the Snedeker house in Connecticut. This case file keeps that record separate from the claim it rates, which is that the paranormal events they reported were real. On that claim the picture is contested: credited hoax admissions and accounts of embellishment attach to several signature cases, skeptics who examined the evidence found it wanting, and nothing was ever independently verified as supernatural, while defenders note the sincerity of the families and the sheer volume of witnesses.
Read the case file →Cicada 3301
Three rounds of ferociously difficult puzzles, posted between 2012 and 2014 and authenticated by a single consistent PGP key, sent thousands of solvers through cryptography, steganography, phone numbers, and physical posters on four continents in search of an anonymous group calling itself 3301. Who built it, and why, has never been established.
Read the case file →Area 51 aliens
The famous claim that a secret Nevada base stores and reverse-engineers crashed alien craft, and why the real, documented secrecy around Area 51 has a far more terrestrial explanation.
Read the case file →BlackRock and Vanguard
Two asset managers keep turning up at the top of nearly every list of a big company's largest shareholders: BlackRock and Vanguard. A popular claim takes that real pattern and runs: the two firms secretly own almost everything and quietly rule the economy, the media, and governments as a hidden cabal. The scale is real, and the concentration is a legitimate subject of debate among economists and regulators. The cabal is not. Most of the money is not theirs; it belongs to the millions of pensioners and ordinary investors whose index funds they run.
Read the case file →Pope John Paul I's death
Albino Luciani, Pope John Paul I, was found dead in his bed on the morning of 28 September 1978, only about 33 days into his papacy. The Vatican said he had died of a heart attack, and no autopsy was performed. Then the details started to shift: the Vatican's first account of who discovered him and what he had been holding turned out to be false, and the corrections looked, to many, like a cover-up. Into that gap stepped a theory that he had been poisoned to stop him from cleaning up the scandal-ridden Vatican Bank. The financial corruption around that bank was real and, as later deaths showed, sometimes lethal. The murder of the Pope himself is a separate claim, and it is one the evidence has never been able to carry.
Read the case file →The Nazi Bell
Die Glocke, German for 'the Bell', is the name given to an alleged top-secret Nazi wonder weapon: a bell-shaped apparatus, said to be several meters tall and filled with a violet, mercury-like substance, that supposedly harnessed exotic physics to defy gravity or bend time. The story entered print in 2000 through Polish journalist Igor Witkowski, who said he was shown, but not allowed to copy, a transcript of the postwar interrogation of SS officer Jakob Sporrenberg. British aviation writer Nick Cook then folded it into The Hunt for Zero Point, tying it to anti-gravity research and a suppressed-technology narrative. This case file separates what is documented (that the Third Reich genuinely pursued advanced weapons, and that some senior SS figures and records went missing in 1945) from the claim it rates (that a functioning anti-gravity or time device existed). On the evidence, the device claim is unproven: there is no physical artifact, no photograph, no verifiable document, and no coherent physics, only a single account of a paper no one else has seen.
Read the case file →Dulce Base
Dulce Base is the claim that a secret, multi-level facility runs beneath Archuleta Mesa near the small town of Dulce in northern New Mexico, jointly operated by the United States government and extraterrestrial greys, where humans are abducted and subjected to genetic experiments, and where, in the fullest versions, a 1979 firefight (the “Dulce Wars”) killed dozens of human security personnel. The story is traceable to one man: Paul Bennewitz, an Albuquerque businessman who from 1979 became convinced that lights and radio signals he recorded near Kirtland Air Force Base were alien. This case file keeps two things apart: a real, unsettling disinformation effort aimed at Bennewitz, plus the ordinary existence of classified sites in the American West; and the claim it rates, an underground base shared with aliens. On the evidence, the base itself is unproven: no physical trace of it has ever been produced, while the legend’s human origins are unusually well documented.
Read the case file →The Enfield Poltergeist
In late August 1977, Peggy Hodgson, a single mother raising four children in a council house at 284 Green Street in Enfield, north London, reported furniture moving and loud knocking that she could not explain. Over the next eighteen months the house became the most famous alleged haunting in Britain. The reported phenomena centred on two of the children, Janet, 11, and Margaret, 13, and included sliding furniture, thrown objects, apparent levitation, and a gruff male voice that seemed to speak through Janet and identified itself as a dead former resident. More than thirty people said they witnessed something, a police officer signed a statement about a moving chair, and two Society for Psychical Research investigators logged roughly two thousand incidents and made about 250 hours of audio recordings. Skeptics documented the girls faking incidents, caught trickery on camera, and argued the investigators were too willing to believe. The sisters themselves later admitted some of it was staged, while insisting most was not. This case file keeps two things apart: a genuinely strange, heavily recorded episode that divided serious investigators; and the claim it rates, that a real poltergeist was at work.
Read the case file →Secret Antarctica
Antarctica is the last near-blank space on the map: a continent larger than Europe, almost entirely buried under ice, that almost no one will ever see. Into that emptiness people have poured a stack of claims. That a lost civilization, even Atlantis, lies frozen beneath the ice. That the Nazis built a secret base there and fled to it after the war. That the US Navy's 1946 expedition was a failed assault on that base. That an ancient map proves the continent was charted ice-free. That the whole place is a guarded no-go zone hiding the truth, or, in the flat-earth telling, an ice wall around the edge of the world. Several of these grow from genuine history, a real Nazi expedition, a real naval operation, a real disputed map, a real treaty. This file keeps the documented cores apart from the unproven leaps, and finds that the hidden-world story the leaps require is not supported by the evidence.
Read the case file →Bob Marley's death
Bob Marley died on 11 May 1981, aged 36, of a melanoma that had started under a toenail and spread to his lungs, liver, and brain. To many admirers that ending felt too cruel and too convenient, and a theory grew up around it: that the cancer was not natural but was induced by the CIA as an assassination. The theory draws on a genuine, disturbing record, the unsolved 1976 shooting at Marley's home two days before a concert, and real CIA hostility toward Jamaica's left-wing government during the Cold War. The best-known version claims Marley was handed a pair of boots rigged with a copper wire or needle that seeded the disease. That last step is where the story leaves the evidence behind: melanoma does not spread from person to object to person, and the documented medical facts explain his death without any plot.
Read the case file →Marilyn Monroe's death
On the night of 4 August 1962, the actress Marilyn Monroe died at her Los Angeles home at age 36. The county coroner ruled the cause acute barbiturate poisoning and the manner a probable suicide. Almost immediately, a counter-story took hold: that she was murdered, often tied to alleged affairs with President John F. Kennedy and Attorney General Robert F. Kennedy, with the CIA, FBI, or organized crime variously implicated, and the evidence tidied away. This case file separates what is documented (a lethal overdose, a genuinely botched death scene, and unanswered forensic questions) from the central claim (that she was killed and it was hidden), which after more than sixty years and an official review remains unproven.
Read the case file →The Yuba County Five
On the night of 24 February 1978, five men from the Yuba City and Marysville area of California, Ted Weiher, Jack Madruga, Bill Sterling, Jack Huett, and Gary Mathias, drove north to watch a college basketball game in Chico, stopped for snacks on the way home, and were never seen alive again. Four had intellectual disabilities and one lived with a psychiatric condition; all were closely tied to their families and to a recreational basketball team, and none had reason to vanish. Days later Madruga's car turned up abandoned, undamaged, and still holding fuel on a remote mountain road far off their route. In June, after the snow melted, four of the men were found dead across miles of forest, including Weiher, who had sheltered in a Forest Service trailer stocked with food and heat he seemingly never used, and who had survived weeks before dying of starvation and cold. Mathias was never found. This case file keeps two things apart: the drive, the car, the recovered bodies, the unused supplies, the failed searches, all on the record; and the claim it actually rates, what happened to them. The leading explanations are steelmanned and weighed here, and none can be shown to be the answer.
Read the case file →Michael Jackson's death
On 25 June 2009, Michael Jackson, 50, was found unresponsive at his rented Los Angeles home while rehearsing for a fifty-date comeback residency, This Is It. The Los Angeles County coroner determined that he died of acute propofol intoxication, a surgical anesthetic that his personal physician had been using to help him sleep, with other sedatives contributing, and ruled the death a homicide. In 2011 that physician, Dr. Conrad Murray, was convicted of involuntary manslaughter and sentenced to four years. Around this documented core grew a set of larger claims: that a wider conspiracy, variously involving the concert promoter, the music industry, or others, had Jackson killed for money or insurance, and, separately, that he faked his own death and is alive. This case file keeps two things apart: a fatal overdose and a physician's criminal conviction; and the claim it rates, a grand plot or a hoaxed death. On the evidence the wider claims are unproven, while the genuine oddities that make people uneasy are set out honestly rather than waved away.
Read the case file →Ananda Mahidol's death
On the morning of 9 June 1946, King Ananda Mahidol of Siam, the eighth Chakri monarch, twenty years old and only months from returning to his studies in Switzerland, was found shot dead in his bed in the Grand Palace in Bangkok. A single bullet had entered his forehead; his own American service pistol lay beside him. A first government announcement called it an accident, but the explanation satisfied almost no one, and three competing readings took hold at once: a careless accident with a handled gun, a suicide, or an assassination. A Commission of Inquiry that year rejected accident while declining to choose between suicide and murder. Politics then took over. A 1947 coup swept out the government of Pridi Banomyong, whose enemies had blamed him for the death, and the new order prosecuted three of the king's aides for regicide. This file separates the documented fact of a young king shot dead from the still-unresolved question of how, and reports the theories through the official record without endorsing any.
Read the case file →Men in Black
The Men in Black are among the most recognizable figures in UFO lore: pale, oddly dressed men in dark suits and hats who arrive after a sighting, seem to know things they should not, and warn the witness to keep quiet. The folklore is real and its history is traceable. It begins in 1953 with Albert Bender, a Connecticut man who ran a small saucer-research club and then abruptly shut it down, saying three men in black had frightened him into silence. The writer Gray Barker turned Bender's story into a 1956 book, and in the 1960s and 1970s John Keel wove the Men in Black into a wider paranormal mythology in which the visitors were not merely government agents but something stranger, robotic, out of place, not quite human. Keep two things apart: a piece of modern folklore with identifiable authors and a clear path of transmission, and the claim this file rates, that a real agency or alien intelligence is actually silencing witnesses. On the evidence the rated claim is unproven: no such organization has been shown to exist, the surviving accounts are anecdotal and sometimes demonstrably invented, and the eerie, mechanical details that define the classic Man in Black read as legend rather than as any plausible agent.
Read the case file →MH370
On 8 March 2014, Malaysia Airlines Flight 370, a Boeing 777-200ER carrying 239 people from Kuala Lumpur to Beijing, dropped off air traffic control screens and was never seen again. It is the most confounding aviation mystery of the modern era: a wide-body jet that vanished in an age of constant surveillance. Into that silence poured theories that the aircraft was hijacked and flown to the US base at Diego Garcia, shot down and hushed up, or spirited away by governments that know the truth. This case file separates what is genuinely documented (the plane really did go dark, the turn-back was almost certainly deliberate, the northern flight path is ruled out by satellite data, and debris consistent with a southern-ocean crash washed up on Indian Ocean shores) from the specific conspiracy claims, which are unproven and, where they require an intact landing, contradicted by the physical record.
Read the case file →The Black Dahlia murder
On January 15, 1947, the bisected body of 22-year-old Elizabeth Short was found staged in a vacant Los Angeles lot, launching a sprawling LAPD manhunt, a flood of false confessions and taunting letters, and nearly eighty years of suspect theories, none of them ever proven, and the case never officially solved.
Read the case file →The Yeren
The Yeren (野人), literally 'wild man', is China's best-known cryptid: an upright, ape-like creature said to stand roughly two metres tall, covered in reddish-brown hair, reported for centuries in the rugged, forested Shennongjia region of Hubei in central China. What sets it apart from most Bigfoot analogues is that the state investigated it directly. After a widely reported roadside encounter in 1976, the Chinese Academy of Sciences mounted a large expedition in 1977, with around 110 zoologists, biologists, photographers, journalists, and soldiers, followed by further efforts into the 1980s. This case file keeps two things apart: a real folklore, sincere sightings, and genuine official expeditions; and the claim it rates, that the Yeren is a living undiscovered animal. On that claim, no specimen has ever been found, the hair and droppings that were tested came back as known animals, and the footprints are best explained as overlapping bear tracks.
Read the case file →Mongolian death worm
The Mongolian death worm, known in Mongolian as olgoi-khorkhoi (roughly “large intestine worm,” because it is said to resemble a length of cattle gut), is a creature of Gobi Desert folklore: a thick, dark red, headless, limbless worm two to five feet long that supposedly surfaces after rain in the hottest summer months and kills anything nearby by spitting a corrosive yellow venom or delivering an electric shock. Nomads have described it for generations, and the explorer Roy Chapman Andrews recorded the tale in the 1920s while leading fossil-hunting expeditions across Mongolia. This case file keeps two things apart. The documented record is the folklore itself, which unquestionably exists and is worth taking seriously as culture. The rated claim is that the animal is literally real with the powers attributed to it. On that question, despite expeditions equipped with everything from Dune-inspired ground thumpers to small explosives, no physical evidence of any kind has ever surfaced.
Read the case file →D.B. Cooper
On Thanksgiving Eve 1971, a man calling himself Dan Cooper hijacked a Boeing 727, collected $200,000 in ransom, and parachuted into the Washington wilderness, and simply vanished. Unlike most conspiracy theories, the strange part here isn't a cover-up. It's that the FBI, with a fully documented crime and real evidence, still cannot say who he was.
Read the case file →Diana's death
Diana, Princess of Wales, died in the early hours of 31 August 1997 when the Mercedes carrying her and Dodi Fayed crashed in the Pont de l'Alma road tunnel in Paris, killing them and the driver, Henri Paul, and leaving bodyguard Trevor Rees-Jones the sole survivor. Within weeks the accident was recast, by grieving relatives and then by a global public, as an assassination staged by the British secret services or the royal family. This case file separates the documented from the alleged. What is documented is that the crash was investigated more thoroughly than almost any road accident in history, and that the French inquiry, the Metropolitan Police's Operation Paget, and a six-month British inquest all concluded it was a tragic accident driven by a drunk, speeding driver and a pursuing pack of photographers, with no evidence of foul play. The claim we rate, that Diana was murdered and the truth concealed, remains unproven and was rejected outright by every inquiry that examined it.
Read the case file →Franco's alien TikToks
In June 2026, James Franco, 48, quietly started a TikTok account and began posting a string of cryptic, low-lit videos. He insisted he was really himself and not promoting anything, then claimed that a creature with glowing eyes, something he described as not human, was lurking in the garage where he paints, and that he believed he was being watched or followed. He promised his followers he would keep filming to prove it and later shared grainy black-and-white footage of a shape moving through his yard. The clips racked up millions of views and set off a wave of alien and conspiracy chatter, memes, and some sincere worry. This case file keeps two things apart: the videos were posted and widely reported, which is on the record; and the claim it actually rates, that a real alien or creature and a real surveillance plot exist as described. On the available evidence, no literal creature or plot has been shown; the range of ordinary explanations, from a deliberate bit to earnest belief, is not something we presume to adjudicate about a living person.
Read the case file →The Tic Tac (Nimitz UAP)
On 14 November 2004, during pre-deployment workups roughly 100 miles southwest of San Diego, off the coast of Baja California, the USS Nimitz Carrier Strike Group logged a genuinely strange event. The cruiser USS Princeton had been tracking anomalous objects on its advanced radar for days. When two F/A-18F Super Hornets were vectored to one, Cmdr. David Fravor and Lt. Cmdr. Alex Dietrich reported a white, wingless, roughly 40-foot object shaped like a Tic Tac, hovering over a patch of disturbed water with no visible wings, exhaust, or means of propulsion, before it darted away at extraordinary speed. A follow-up jet captured the now-famous FLIR1 infrared video. In 2017 the story broke publicly, and in 2020 the Department of Defense formally released the footage and confirmed it was authentic and unidentified. This case file keeps two things apart: a credible, multi-sensor, multi-witness encounter with an object that has never been positively identified; and the claim it rates, that the object was an extraterrestrial or non-human craft defying physics, which remains unproven.
Read the case file →AI-washing layoffs
By 2025 and 2026, “AI is taking the jobs” had hardened into conventional wisdom, repeated in earnings calls and layoff memos across the technology sector. This file examines the counter-claim: that in many cases the story is spin. Outplacement firm Challenger, Gray & Christmas logged artificial intelligence as the stated reason for roughly 55,000 announced job cuts in 2025, a real and growing number, yet a small share of the more than a million cuts announced that year. Meanwhile a large academic survey of thousands of executives found that around nine in ten firms reported no impact from AI on employment or productivity over the previous three years, and analysts noted that many companies announcing “AI-related” layoffs did not yet have the mature AI systems that would be needed to actually replace those workers. Some executives said the quiet part aloud: Amazon's chief executive told analysts that a 14,000-person corporate cut was “not really” AI-driven. The pattern has a name, AI-washing, and this file weighs how much of the AI-layoff wave is genuine automation and how much is a more flattering label for over-hiring and cost-cutting.
Read the case file →The Peter Bergmann case
In the second week of June 2009, an unidentified man arrived in Sligo, in the northwest of Ireland, and checked into the Sligo City Hotel under the name “Peter Bergmann,” giving an Austrian address that does not exist. Over the next four days he was recorded on the town's CCTV cameras leaving the hotel again and again with a purple plastic bag full of items and returning without it, apparently scattering his belongings around Sligo. Every label had been removed from his clothing, and he carried no identification. On the morning of 16 June his body was found on the beach at Rosses Point. A postmortem revealed advanced terminal cancer and severe heart disease, and the inquest found he had died of natural causes. Despite a five-month investigation and international enquiries, the Gardai never learned his real name. This file separates what the cameras and the pathologist documented from the still-open question of who he was and why he came to Sligo to disappear.
Read the case file →The Fouke Monster
The Fouke Monster is a Bigfoot-type cryptid said to roam the Sulphur River bottoms near Fouke, a small town in southwestern Arkansas. Reports of a tall, hairy, foul-smelling creature date back to the 1940s, but the legend exploded in May 1971 when Bobby and Elizabeth Ford told authorities that a hairy, red-eyed creature had reached through a window and grappled with Bobby outside their rented home; he was treated at a Texarkana hospital for scratches. A Texarkana Gazette reporter named the creature, a Little Rock radio station posted a bounty, and hunters poured into the area, where three-toed tracks were found. The 1972 film The Legend of Boggy Creek, shot around Fouke with local residents, made the story a nationwide sensation. This case file keeps two things apart: genuine, sincerely reported scares in a remote swampland; and the claim it rates, that a real unknown animal is responsible. No specimen has ever been recovered, the tracks were called a probable hoax, and investigators argue a black bear explains the sightings. On the evidence the creature's existence is unproven.
Read the case file →Bennington Triangle
Between 1945 and 1950, at least five people disappeared in the rugged country around Glastenbury Mountain in southwestern Vermont: an elderly hunting guide, an 18-year-old college student, a war veteran on a bus, an 8-year-old boy, and a 53-year-old woman whose body was the only one ever recovered. Decades later, Vermont author Joseph A. Citro grouped the cases under the name 'the Bennington Triangle.' The disappearances are real and mostly unsolved; whether they add up to anything more than a run of tragedies in dangerous terrain is the question.
Read the case file →Kryptos
Kryptos is a curved copper screen, sculpted by artist Jim Sanborn and installed in 1990 in a courtyard at CIA headquarters, whose surface is punched with roughly 865 characters of ciphertext in four sections. Three were solved by the mid-to-late 1990s and reveal poetic and archaeological passages. The fourth, 97 characters beginning OBKR, has never been publicly cracked. Over the years Sanborn has released a handful of plaintext clues, and in 2025 he auctioned the solution itself, yet the message remains one of the world's most famous unsolved codes.
Read the case file →Havana Syndrome
Beginning in late 2016, US diplomats and intelligence officers in Havana reported a frightening set of symptoms: a sudden sensation of pressure or piercing sound, followed by headaches, dizziness, ringing ears, and lasting cognitive problems. More than 1,000 of these 'anomalous health incidents' have since been reported worldwide. This case file separates two things that are often merged. The symptoms are real, sometimes disabling, and deserve to be taken seriously. The specific conspiracy claim, that a foreign adversary struck personnel with a secret microwave or directed-energy weapon and that the US government is concealing the true cause, is the claim rated here, and on the current record it is unproven: the March 2023 Intelligence Community assessment found a foreign adversary 'very unlikely', while a 2020 National Academies report and a number of unexplained cases keep the medical question genuinely open.
Read the case file →The Florida Skunk Ape
The Skunk Ape is Florida's answer to Bigfoot: a bipedal, hair-covered creature, said to stand five to seven feet tall and to announce itself with a stench compared to rotten eggs, garbage, or a wet skunk, reported for decades in the swamps and sawgrass of the Everglades and Big Cypress. Sightings run back through Florida newspapers of the 1950s and 1960s and surged in the 1970s and again in 1997. The legend is real, complete with a research headquarters, a famous set of 2000 photographs mailed anonymously to a county sheriff, and a state legislator's failed 1977 bill to make harming one a crime. This case file separates that documented folklore from the claim it rates: that an actual, undiscovered population of large apes lives in the Florida wetlands. On that claim, after seventy years without a specimen, the record is anecdotal and the photographs are disputed, and skeptics who point to bears, escaped primates, and hoaxes have the stronger hand.
Read the case file →The Loveland Frog
Loveland, Ohio, a quiet suburb northeast of Cincinnati, is home to one of America's more endearing cryptids. The story begins with a 1955 account by a businessman who reported seeing several roughly three-to-four-foot, frog-faced humanoid figures with leathery skin near a bridge over the Little Miami River. It became famous in 1972, when two Loveland police officers, on separate nights two weeks apart, each reported seeing a large frog-like animal near the same stretch of road. The claim we rate is that these encounters point to a genuine unknown amphibious humanoid. This file keeps that claim apart from the record: real people, including trained officers, did report unusual sightings. What has never appeared is a body, a bone, or a photograph of any such species. One of the 1972 officers later said flatly that what he saw and recovered was a tailless pet iguana. On the evidence, the existence of a Loveland Frog is unproven, and the town has largely made peace with the mystery by turning it into a mascot and a musical.
Read the case file →The Mngwa (Nunda)
Along the coast of Tanzania, in the old Tanganyika, folklore speaks of the mngwa, Swahili for the strange one, also known as the nunda. It is described as a cat the size of the largest lion, but greyish and marked with brindled, tabby-like stripes, moving in silence through the coconut groves and killing people before vanishing. The tradition is genuinely old, surfacing in Swahili storytelling collected in the nineteenth century, and it acquired a documentary spine in 1922, when a British colonial magistrate, Captain William Hichens, recorded a series of deadly maulings at Lindi whose paw prints looked like a leopard's but were the size of a lion's, and whose victims clutched tufts of coarse grey fur. This case file holds two things apart. What is on the record, a durable folk creature and a real, unexplained cluster of killings, is one thing. The claim we rate, that a large cat unknown to zoology is the cause, is another. On the physical evidence that survives, which is thin and inconclusive, and against ordinary alternatives, that claim is unproven.
Read the case file →Gloucester sea serpent
In August 1817, the harbor at Gloucester on Cape Ann, Massachusetts, filled with reports of a strange animal: dark, very long, moving through the water in a series of humps or bends, with a head some compared to a horse or a sea turtle. The witnesses were not a fringe few. They numbered in the dozens and included fishermen, ship carpenters, and captains, several of whom swore formal depositions. A learned body, the Linnaean Society of New England, appointed a committee, circulated a questionnaire, collected the sworn statements, and published a report, briefly classifying a small washed-up snake as the serpent's progeny under the name Scoliophis atlanticus. This case file separates the documented record (a genuine wave of credible-seeming sightings and a real scientific inquiry) from the rated claim (that an actual unknown giant sea serpent was responsible). No specimen was ever recovered, the supposed offspring proved to be a deformed common blacksnake, and the sightings fit known animals and sea-surface illusions. On the evidence, the existence of a true sea serpent is unproven, while the historical event itself is beyond doubt.
Read the case file →Lagarfljót Worm
Lagarfljót is a long, narrow, glacier-fed lake beside the town of Egilsstaðir in eastern Iceland. For centuries its waters have been said to hold an enormous serpent, the Lagarfljótsormur, or Lagarfljót Worm. The earliest hint is a line in a medieval annal noting a strange marvel in the lake in 1345, and the creature later appears on old maps, in a 17th-century chronicle and poem, and in the folk tales collected by Jón Árnason in the 19th century. Sightings have continued into modern times, and in February 2012 a farmer, Hjörtur E. Kjerúlf, filmed a serpentine shape moving in the icy river that went viral worldwide. A local commission later voted, narrowly and non-bindingly, that the video did appear to show the creature, and the man who filmed it was paid a long-standing reward. This case file keeps two things apart: a genuine, centuries-old folk tradition and a disputed piece of footage; and the claim it rates, that a real, undiscovered animal lives in the lake. No physical specimen has ever surfaced, and the murky glacial water lends itself to illusion. On the evidence, the literal-creature claim is unproven.
Read the case file →The J'ba Fofi
The J'ba Fofi (a Baka phrase usually glossed as "giant spider") is a cryptid reported from the rainforests of Cameroon and the Democratic Republic of the Congo. In folklore it is a brown, tarantula-like spider with a leg span of three to four feet, sometimes said to reach five or six, that builds leaf-covered lairs and strings near-invisible trip-lines across game trails to catch prey as large as small forest antelope. The best-known Western account dates to 1938, when the explorers Reginald and Margurite Lloyd are said to have watched a large spider cross a jungle trail in the Belgian Congo. This case file keeps two things apart: a genuine Indigenous tradition and a handful of anecdotal reports; and the claim it rates, a literal, undiscovered spider several feet across. On the evidence, the existence claim is unproven: it rests entirely on stories, produces no specimen, and describes an animal that the biology of spiders makes extremely unlikely at the stated size.
Read the case file →Thunderbird
The Thunderbird sits at the crossroads of two things that deserve to be kept apart. In the traditions of many Native American peoples the Thunderbird is a powerful and sacred being, a real and meaningful figure in living cultures, and nothing in this file is a comment on that. The cryptid claim is a modern, separate proposition: that an actual, undiscovered giant bird, with a wingspan wildly beyond any known species, physically exists over North America and accounts for reports of monstrous winged animals. The lore has memorable anchors: an 1890 story in an Arizona newspaper about cowboys who supposedly shot a huge winged creature near Tombstone, and the famous Thunderbird photograph, a picture many people are certain they once saw of men posing beside an enormous bird nailed to a barn wall, which no one has ever been able to find. This case file separates the documented record (the cultural figure, the newspaper text, the psychology of a photograph nobody can locate) from the rated claim (a living giant bird awaiting discovery). On the evidence, that claim is unproven: no body, no verifiable image, no supporting fossil record, and sightings that fit known large birds seen under conditions that defeat size estimation.
Read the case file →The Owlman of Mawnan
The Owlman of Mawnan is a winged, owl-faced humanoid said to have been seen near the church of St Mawnan and St Stephen, on the Helford River in Cornwall, beginning in 1976. In the best-known account two young sisters on holiday, June and Vicky Melling, were said to have been so frightened by a large bird-man above the church tower that their father cut the family holiday short. Further reports followed that summer and sporadically into the 1990s: a creature about the size of a man, grey or silver-feathered, with pointed ears, glowing red eyes, and pincer-like claws. This case file keeps two things apart: a run of anecdotes, a local pamphlet, and a lively Fortean paper trail; and the claim it rates, that a genuine unknown animal or paranormal entity was behind them. The central problem is that nearly every thread runs back to Tony (Doc) Shiels, a surrealist painter, stage magician, and admitted hoaxer who was raising monsters in Cornwall that same year. On the evidence available, the existence of the Owlman is unproven, and the ordinary explanations, from large owls to a showman's invention, remain unrefuted.

The Pope Lick Monster, more often called the Goat Man, is said to be a part-human, part-goat creature that lives beneath the Pope Lick railroad trestle in the Fisherville neighborhood of Louisville, Kentucky. In the legend it lures or hypnotizes trespassers onto the high bridge, where an oncoming train finishes them. The story has circulated locally since at least the 1960s and reached a wider audience through a 1988 short film. This case file separates two very different things. The creature is folklore with no evidence of any kind. The trestle, by contrast, is real and lethal: it is an active freight bridge roughly 90 feet high, and several people lured or dared onto it, some of them explicitly hunting the monster, have died there. The danger in this story is not supernatural.

On the night of August 21–22, 1955, the Sutton family and their guests, at a farmhouse near Kelly, Kentucky, said small silvery creatures with glowing eyes, huge ears, and clawed hands laid siege to their home for hours. The men emptied shotguns and a rifle into the figures with no effect. The terrified family fled to the police, who returned with some twenty officers and found nothing. The event is real and well-documented; its cause is disputed, with great horned owls the strongest ordinary explanation.
