The Beaumont Children were three siblings that vanished from a beach in South Australia in 1966, and it remains Australia's longest-running missing persons case.
JoNo 7 hours ago (edited)
This case is so sad. For Mr & Mrs Beaumont to have all of their three children disappear at the same time meant life would never be the same. With no children, they later divorced and lived very long lives not knowing what happened to their precious Jane, Arnna & Grant. Nancy Beaumont died in 2019, aged 92. Jim Beaumont was 97 when he died in 2023. I like to think they have been reunited with Jane, Arnna and Grant in the afterlife. The suburban beach they disappeared from is in Adelaide, the capital city of South Australia, where I live. Over the years there are updates on the case in the local press (eg, when both Nancy & Jim passedd away) and possible leads that never eventuate.

About four months ago they thought here would be a break in the case because they got permission to do more extensive excavation on a place of interest. I'm not really surprised we haven't heard more though.

In 1971, a man calling himself D.B. Cooper hijacked a Boeing 727 during a flight from Portland to Seattle. He calmly demanded $200,000 in cash and four parachutes, released the passengers once he got what he wanted, then ordered the crew to take off again at low altitude. Somewhere over the Pacific Northwest, in the middle of a storm, he lowered the rear staircase and parachuted into the mountainous, heavily forested terrain, at night no less, with the money.
No one knows who he was, where he landed, or whether he even survived the jump. Despite one of the most extensive FBI investigations in history, Cooper was never identified or captured, and the case remains the only unsolved act of air piracy in the United States.

According to the internet they identified who assassinated him but by that time the suspect had already died.

It wasn't him, every swede with a brain knows that. Clues led to law inforcement and to people in high power positions. This will never be solved.

Our Prime Minister the leader of Australia Harold Holt went missing going swimming. Up and vanished without a trace. There was speculation he was picked up by a Chinese sub amongst other theories. We often use the slang doing the Harry if you leave something early i.e I got tired of the pub so I did the Harry and went home. We also named a pool after him.

Not that big a mystery. There is a 99% chance he got into trouble in the water and just never found his body. Very similar to Amelia Earheart.

The mystery that I want solved the most is what happened to the Alcatraz escape crew: Frank Morris, John and Clarence Anglin. My heart says that they had to have survived. I see so much evidence for thier successful escape. I'd truly need professional counseling if I found out that these men died in their attempt at freedom. My heart needs them to have made it.

I have visited Alcatraz and the Sea was extremely choppy and heavy winds, doubt they survived.

Jack the Ripper.
Often sighted as the first internationally famous serial k*ller.

Not proven. DNA was supposedly found on a shawl belonging to a victim. There is a lot of doubt that the shawl actually belonged to the victim as there was no record of a shawl at the crime scene, and it was brought at a private auction by a writer called Russell Edwards. Edwards is a conspiracy theorist and attention seeker. He also claimed to have found the body of Keith Bennett (victim of Myra Hindley and Ian Brady) but that turned out to be bollocks.

Only found out recently (due to BBC series with Lucy Worsley) that another serial k1ller, the Thames Torso mvrderer, was operating in a similar area at the same time. The MO was different, so they don't think it's the same person - she identified a boatman called James Crick as the most likely perpetrator.

Mona Elizabeth Blades was an 18-year-old New Zealand woman who disappeared on 31 May 1975 while hitchhiking. Her body and belongings have never been found and no one has been charged in connection with her disappearance and presumed m****r.

Brian Shaffer, a 27-year-old medical student, disappeared on April 1, 2006, after being last seen on security footage entering the Ugly Tuna Saloona bar in Columbus, Ohio, but never appearing to leave, despite cameras at all exits. His disappearance is a baffling cold case, as he vanished from a crowded bar without a trace, with no evidence of foul play or voluntary disappearance, and his phone, wallet, and credit cards were left behind
He was never seen leaving the bar on any security footage, even though cameras covered all exits, including a construction area.

So there was a construction area at the bar? Hmm. Reminds me of a case from Wales a few years ago.

Two of Argentina’s most interesting unsolved mysteries are the Jesuit Treasure and the secret tunnel networks found in several cities.
The Jesuit Treasure comes from the Misiones region: when the Jesuits were expelled in 1767, legend says they hid a massive amount of gold, silver, and documents in underground chambers. Many expeditions have tried to find it, but no solid evidence has ever appeared, so it remains a mix of history and myth.
Another long-running mystery involves the underground tunnels. Buenos Aires has colonial tunnels in San Telmo and Montserrat whose real purpose is still debated—smuggling, drainage, hidden storage, or something else. The strange part is that many sections don’t match the official city plans of the era.
And it’s not just Buenos Aires: Córdoba, Salta, Mendoza, and several older cities also have undocumented tunnels from colonial times that no one fully understands. Some are sealed, some reappear during construction, and almost none have proper historical records explaining why they were built.
All of this leaves Argentina with a surprising amount of underground mysteries still unsolved.

The one that immediately comes to mind for me is the Great Mull Air Mystery.
Christmas Eve 1975 a guy decides to go on a drunken night flight from the Glenforsa airstrip, a small grass airstrip on the Isle of Mull owned by the Glenforsa Hotel, in a Cessna he rented from the hotel manager. He takes off, and disappears. His dead body was later found in a felled tree a few months later, with no trace of salt or marine life on him, or his clothes
In the 2000s a handful of Royal Navy ships were mapping for Naval Mines off Oban, when they found an aircraft that was possibly his, with the doors locked from the inside, no windscreen, and missing a wing.

Sinking of the MS Estonia.
MS Estonia, a cruiseferry operated by Estline, sank on Wednesday, 28 September 1994, between about 00:50 and 01:50 as the ship was crossing the Baltic Sea, en route from Tallinn, Estonia, to Stockholm, Sweden.

Left their passports, wallets, everything at home. Only missing was their car and themselves.

There was once a rain of chunks of meat in some United States town in the nineteenth century, I read. The article I read that on said there wasn't a consensus on what caused the rain of flesh.

This guy, Colosio, was campaigning to become the president of Mexico. He was a member of PRI and it was 1994 so he was surely going to be elected except some lone shooter k****d him.
Everyone thinks it was Salinas, the incumbent president ( and who had hand picked him as the candidate) but we'll never know.

Another conspiracy theory. The investigation at the time was unable to confirm the exact reason for the plane crash, but equally, nobody was ever been able to provide evidence against it being an accident.

He was the one who gave us independence not gandi. White people made sure to erase his legacy. He was reported to be dead in plane crash, but in recent years we found out there were zero plane crashes in that year all together. There are theories that he is still alive.
His name is subhash chandra bose.
David Andrews 7 hours ago (edited)
No. He was involved in the Independence movement, but he certainly was not the one to give India independence. White people did not "erase his legacy", he was a rich, right wing authoritarian believer, who allied himself with N**i Germany and Japan. That, and arguing with Ghandi is what got him sidelined by the Congress party and out of the legitimate independence movement. Allied with the Japanese government he then used POWs as his own little independence army, which was quickly and easily defeated after they tried to invade India. No plane crashes in that year is a ridiculous statement as it was WW2, and you also would have to ignore the evidence, eye witnesses, survivors and investigations carried out that support the plane crash

It seems unlikely he'd still be alive, given that Friday would be his 129th birthday.

DB cooper is mysterious, but generally we have a very, _very_, long history of spooky and mysterious s**t, some of it ongoing.

I live in the region where he supposedly jumped. People disappear out here every month when they know where they are going. Falling onto some random slope in a storm though? If the terrain and exposure don't k**l you, the wildlife will.
He probably was never found because he was eaten and the cash washed away or buried under rock slide debris.

Belgium here: the theft of the 'Just Judges', part of a large alter piece in Ghent Cathedral. In the 1930's two panel were stolen and a ransom request was send to the Bishop of Ghent. One panel was returned as a sign of goodwill, but the Just Judges remain missing. The identity of the thief was never fully confirmed. Every year, usually in Summer, when news is slow, there will be some new book/theory/search for the missing panel.
