Across different eras and regions worldwide, there have been numerous credible accounts of crimes and attacks targeting humans—and occasionally animals—that remain unresolved to this day. The cases listed here are presented without any specific order, as each one is equally captivating and astonishing. While many of these incidents lack identifiable culprits, they all share a common trait: they occurred under the most peculiar and bewildering circumstances, challenging all logical reasoning and leaving us questioning their true nature.
10. The Whiteface Texas Animal Mutilation

In Whiteface, Texas, during early 1975, an area where UFO sightings had been frequent for weeks, authorities discovered a mutilated calf on March 10th. Rancher Darwood Marshall found the young animal lying within a 30-foot circle of flattened crops. Its neck was unnaturally twisted skyward, its tongue had been forcibly extracted, and its reproductive organs were also missing.
A few days earlier, Marshall had found a mutilated steer lying in a patch of scorched wheat. Sheriff Richards conducted radiation tests at the site, which yielded positive results, prompting him to seek assistance from experts at Reese Air Force Base. Their analysis showed radiation levels slightly above normal—just half a percent higher—though not enough to cause alarm. However, the presence of any radiation discrepancy and the mysterious scorched wheat circle raised unanswered questions.
9. Mysterious Helicopters Over New Mexico

On April 8, 1979, two Apache tribal officers patrolling near Dulce, New Mexico, spotted an unidentified aircraft hovering approximately 50 feet above the ground, shining a bright spotlight onto a field. A third officer speculated it might be linked to recent livestock disappearances, as it was near areas where such incidents had been reported. The craft remained unidentified, though one individual suggested it could be a quiet jet-powered helicopter developed by the U.S. military during the Vietnam War.
Five years earlier, on July 5, 1974, Robert Smith, Jr. reported seeing a white helicopter and a black twin-engine aircraft while working in a tractor near the Nebraska border. The helicopter allegedly fired at him, though neither aircraft bore any registration marks, as required by law. Authorities were unable to trace the crafts, and the presence of unmarked helicopters near sites of livestock mutilations and disappearances fueled fears among ranchers about cult activity in the region.
8. The Disappearance of Ireland’s Crown Jewels

One of the most audacious heists of the 20th century took place in 1907 when Ireland’s crown jewels, worth $250,000, were stolen from a secure safe in the strong room of Bedford Tower at Dublin Castle. The theft occurred under the watch of four guards tasked with protecting the jewels. Between June 28th and July 6th, the thief managed to acquire keys to the tower’s main door, the strong room, and finally the safe, where they spent at least 10-15 minutes removing the jewels from their cases—all without raising suspicion. Despite a lengthy investigation by Scotland Yard, the jewels’ location and the thief’s identity remain a mystery.
7. The Vanishing Matron of Paris

In May 1889, a distressed young Englishwoman arrived at the British Embassy in Paris. She explained that she and her mother, returning home from India, had stayed at a hotel after her mother fell ill. A hotel doctor examined her mother and sent the daughter to fetch medicine. Upon her return, the staff denied any knowledge of her mother, and only her name appeared in the hotel register. When she demanded to see the room her mother had stayed in, it was not the one she remembered, and even the doctor claimed never to have met her.
Unable to convince anyone of her story, the young woman was eventually placed in an asylum in England. Some theorized that her mother had contracted the plague in the Far East, and the hotel had conspired to hide the incident—even redecorating the room and disposing of the body—to avoid losing business. The only evidence supporting the disappearance was the daughter’s testimony, which some dismissed as madness. Yet, if true, the ordeal would have been enough to drive anyone to insanity.
6. The Disappearance of the Three Lighthouse Keepers

As the supply ship ‘Heperus’ neared Eilean Mor, an island off Scotland’s West Coast, there was no activity visible onshore. Joseph Moore, a lighthouse keeper from a nearby island and the relief keeper for Eilean Mor, grew increasingly worried: the lighthouse had been dark for 11 days.
Moore and his team thoroughly searched the lighthouse, finding everything in place except for the oilskin foul-weather gear belonging to two of the three keepers, which was missing. Damage to the jetty from a storm hinted that the men might have been swept away by a massive wave. However, it seemed unlikely that all three would have ventured onto the jetty during such severe weather. The mystery deepened as none of the keepers were ever found, leaving the incident unresolved.
5. The Miami – Scarsdale Vanishing

Charles R. Romer and his wife, Catherine, were no strangers to the long drive between Miami, Florida, and Scarsdale, New York. The elderly couple, both in their seventies, had spent the winter of 1980 in their Florida apartment and began their journey home on April 8. That afternoon, they checked into a motel in Brunswick City, Georgia. Later, a highway patrolman spotted their black Lincoln Continental on the road, possibly heading to a restaurant for dinner.
However, they never reached their destination. The couple and their car vanished without a trace. Three days later, the motel staff noticed their room had not been used and alerted the authorities. Police were left baffled, speculating that the Romers might have driven into a swamp or fallen victim to a robbery or worse. Aside from their luggage in the motel and a brief sighting of their car, there were no other clues. Their son remarked, “It’s unbelievable that two people can completely disappear.” Unbelievable—yet true.
4. The Enigma of the Locked Room

On March 9, 1929, Isidore Fink was fatally shot at 10:30 p.m. in the back room of his Fifth Avenue Laundry located at 4 East 132nd Street in New York City. A neighbor, Mrs. Locklan Smith, heard screams and the noise of a struggle, prompting her to alert the police. Upon arrival, officers discovered the room’s doors locked and had to lift a small boy through a transom window to gain entry.
Fink had sustained two gunshot wounds to the chest and one through his left hand, which displayed powder burns. No weapon was found in the room, and money remained untouched in both Fink’s pocket and the cash register. Initially, police speculated that the assailant entered through the transom window, as Fink typically bolted the doors while working at night. However, the window was small, and it seemed illogical for a fleeing murderer to use such an exit instead of the door. Another theory suggested Fink was shot through the transom from the hallway, but the powder burns indicated close-range shots. Over two years later, New York Police Commissioner Edward P. Mulrooney declared the murder an “unsolvable mystery.”
3. The Disappearance on Everest

On June 8, 1924, George Leigh-Mallory (pictured: second left, back row) and Andrew C. Irvine were just under a thousand feet from Everest’s summit when swirling snow and mist obscured them from the view of the base camp telescope. They were never seen again. While Everest was officially conquered in 1953, the intriguing possibility remains that these two men might have reached the summit nearly three decades earlier.
Leigh-Mallory, 36, had joined two previous Everest expeditions. The leader of this third attempt described him as the “driving force behind the mission; it had become a personal quest for him.” Irvine, 22, lacked extensive climbing experience but excelled in handling the heavy oxygen equipment. The pair had camped at 26,800 feet the night before, sending their Sherpa guides down to inform the team of their plan to summit early the next day. However, they started late or were delayed during the climb, as they were last seen at 28,227 feet at 12:50 p.m. on the eighth. Clouds soon enveloped them, and the only trace ever found was an ice axe belonging to either Leigh-Mallory or Irvine, discovered along their route in 1933. Speculation suggests they may have fallen into a crevasse or been buried by an avalanche, their fate forever hidden in the icy expanse of Everest.
2. The Mystery of the Cave Children

In August 1887, two children emerged from a cave near Banjos, Spain. Their green-tinted skin and strange clothing immediately drew attention. They spoke no Spanish, and their eyes had an Oriental appearance. Initially refusing to eat, the boy succumbed to starvation, but the girl lived long enough to share a cryptic tale. She claimed to hail from a “land without sun” and described being swept up by a whirlwind, which deposited her and her companion into the cave. Her story only deepened the mystery, and she passed away in 1892, her origins forever unknown.
1. The Mystery of the Severed Ears

In January 1977, The Jasper County News in Mississippi reported a bizarre series of attacks on hogs. Joseph Dickinson, a resident of the Nazarene Community, discovered one of his hogs with its ears cleanly sliced off, as if by scissors. The following nights, two more hogs were targeted in their pens. On the third night, Dickinson spotted an animal in the pen—larger than a German Shepherd and capable of extraordinary leaps. A week later, Calvin Martin, a neighbor, found one of his sows with its ears torn out by the roots, adding to the unsettling mystery.
