Unsolved mysteries involving children are some of the hardest to hear or read about.

Yves Bert was in first grade when he was kidnapped at the gate of his school. On July 4, 1978, his parents received a letter stating: “I am writing to you because I have very good news about your son. Since we cannot have a child, we felt that we had to resort to kidnapping, but now we are tortured by remorse and have decided to return your child to you.”

The family received three other letters in the following months, but they never saw any sign of their son. The case was opened again in 2009 to look for new evidence using DNA technology, but this unsolved mystery still has too many questions.

31.) The Reincarnation Case of the Pollock Sisters

The story starts when two English sisters, Joanna and Jacqueline Pollock, died in a tragic car incident. Their mother gave birth to twin sisters one year later, and things started getting weird.

The twins requested their deceased sisters’ toys, pointed to details only the sisters could know and panicked when they saw cars saying, “That car is coming to get us.”

The incidents subsidized when the twins turned five, and over time the incidents stopped. However, the incident is still vivid in the memory of many as they believe it is a case of resurrection.

30.) Scotland’s Big Grey Man

Beware of the Big Grey Man if you are visiting Scotland. This hauntingly inhuman creature is believed to live in the summit of Ben Macdui. Eyewitnesses describe it as an extremely tall human-like creature with long arms, broad shoulders, and short hair. They also have heard gravel being crunched as the creature was moving.

While scientists couldn’t find a logical explanation to the sightings, they attributed them to the exhaustion and isolation the eyewitnesses must have been feeling at the time.

The previous family maid quit after saying the house was haunted, a strange newspaper from Munich was found on the property and mysterious footprints coming from the forest were discovered.

In 1908 in Siberia, Russia, one alarmingly strange event happened. Almost 770 squares of forest were completely flattened, as if being wiped after a collision. Except, there was no crater anywhere in sight.

Scientists venture that it might have been an after-effect of an asteroid that exploded over the earth, and not with it, thus wiping out the area. They couldn’t prove for sure that this was really what happened though.

25.) The Alcatraz Fugitives

Unsolved mysteries involving jailbreak are particularly striking. How can someone escape a closed heavily guarded institution? And how is it possible when it is an isolated prison-like Alcatraz, which is on an island in San Francisco Bay?

Three inmates — Frank Morris, and brothers John and Clarence Anglin — masterminded the operation. They made dummy heads with soap and concrete to trick the guards, pulled out the entire ventilation shaft under their cells’ sinks and used the plumbing to climb up.

The escapees then inflated a raft made with raincoats and a concertina. No one saw them again.

24.) The Strange Noises

In 2016, three CIA officers came to the American Embassy’s health office in Havana to report their medical condition. They were suffering from nausea, dizziness, and headache. No one knew the reason behind it.

By the end of 2018, the number grew to reach 26 Americans and 13 Canadians. The victims claimed these symptoms started after they heard some strange noise at their hotel rooms. No medical expert could explain the reason for these symptoms. Many people suspected it could be the work of the Cuban government, but the latter strongly denied any involvement. We still don’t know the origin of that noise to this day.

23.) The Keddie Murders

The once-quiet 1976 town of Circleville, Ohio, saw its calm shaken to the core with the Circleville Letter Writer.

The anonymous author threatened many residents of the town with serious personal details. The most dangerous ones were written to the local bus driver Mary Gillispie. The writer accused her of having an affair with the superintendent of schools and asked her to admit the truth to the school board.

Her husband, Ron, received a phone after a year and went out infuriated. He was later found dead in his car. After many other unnerving signs, Mary’s former brother-in-law, Paul Freshour, was arrested for Mary’s attempted murder. However, he began receiving threats from the Circleville Letter Writer when he was in prison!

Coming from somewhere in Russia, UVB-76, or “The Buzzer,” has been baffling decades of conspiracy theories fanatics and paranormal activity enthusiasts.

This Russian radio software station broadcasts on the frequency 4625 kHz. It only a monotonous buzz tone 24 hours/day. The most curious cases happen when the buzzing stops and a short voice transmission replaces it. Everyone is speculating about the meaning of this signal, but no one could solve this riddle.

Catacombs are sinister on their own; no one can deny that. Especially not internet users who are familiar with Odessa’s Catacombs’ case.

It all began when Masha, a young woman who went out to the Odessa Catacombs in Ukraine to celebrate the New Year of 2005. All her friends turned up from the tunnels, but she didn’t appear. Her body was never found, and only Ukrainian cave explorers claim to know the details of this curious case. Some people think this story is a lie, but no one knows for sure.

It all started in 1900 when the Flannan Isles Lighthouse was manned by three individuals: Thomas Marshall, James Ducat, and Donald MacArthur.

When the relief team came by, they couldn’t find anyone of the keepers. Apart from that, there was nothing out of the ordinary, except an overturned chair. Speculations include a group of spies who drowned the keepers, a sea monster who unleashed its rage upon them, and even a ghost ship. Which theory do you think would be more plausible?

7.) The Sleeping Sickness

sleeping sickness unsolved mysteries

Ever felt the horror of sleep paralysis? Sleeping sickness is kind of the same, except it plagues people for life, and can even kill.

Over half a million people were afflicted with a weird condition from 1917 to 1928. They would find themselves unable to move any part of their bodies despite being fully aware of their environment. One theory ventured that this would be the cause of brain inflammation triggered by a unique strain of streptococcus. This calamity resurfaced on two occasions, once in the 1950s and later in 2004.

6.) The Crimes of Serial Killer Samuel Little

Samuel Little confessed to killing 93 people over 35 years since 1970.

Police and federal law enforcement started scouring all documents available in an effort to find connections between some unsolved crimes and Little’s murders, but this case is still surrounded in mystery.

Little considered himself an accomplished artist and promised he would draw his victims from memory. He drew 16 portraits of the women he killed using a mix of chalk, pastel pencils and watercolors.

5.) Brazil’s Ruins

Robert Marx is a professional treasure hunter who unearthed what must have been the biggest treasure in his career. In 1982, he found 200 Roman ceramic jars, some fully intact, 15 miles from the shore of Brazil’s Guanabara Bay.

What’s the most mysterious about them is that the Europeans didn’t reach Brazil until the 1500s while these jars were clearly way older than that. How could such a big number of jars end up in one place with no way in or out of the area?

4.) The Golden State Killer

unsolved mysteries golden state killer

While there are many serial killers in this list, a lot of which are from the past decades, there are some that the public remembers vividly. The East Area Rapist, the Original Nightstalker and the Golden State Killer all likely refer to the same person.

This serial killer and rapist had raped at least 50 women in Northern California in the 70s, although he’d never been identified.

He sent letters and drawings to newspapers to show them his targeted area. He would call his victims to taunt them. It was even believed that he did attend a town meeting discussing his crimes. The photo above is a hand-drawn map the killer used to represent his ideal setting.

However, this unsolved mystery might not be a mystery for much longer. A man named Joseph DeAngelo was arrested on April 24, 2018, as the suspected killer after using DNA evidence to track him down.

3.) The Kecksburg UFO Incident

This seems like it comes straight out of a Steven Spielberg script! On December 9, 1965, thousands of eyewitnesses from six different U.S. states and Canada reported seeing a strange light.

They could see it over Detroit, Michigan and Windsor, Canada. It seemed like a fireball crashed on the site. Speculations ranged from it being an alien craft, space debris and a Russian satellite.

When single mom Christine Collins reported her nine-year-old son, Walter, missing, she expected everything but what happened next.

Five months after the original report in 1928, the police came back to Christine with a new body, saying it was Walter. Except, it wasn’t. Christine shouted and cried but the police were adamant and even accused her of being a bad mother. The issue went as far as the police admitting her to a mental hospital.

Walter Collins’ real body was never found and no one knows why the police were so keen on covering up for the matter.

1.) Area 51

area 51

The public has been speculating about Area 51 for a very long time. In 2013, the CIA was forced to respond to a Freedom of the Information Act request and reveal that it is a U.S. military base.

Satellite images don’t show the area (you can even check on Google Maps), and no planes go over it. Rumors say that it is a base to develop and test experimental aircraft and weapons or UFO-related activities.
