Status: Unsolved
Location: Glenelg Beach, Adelaide, South Australia
Date: 26 January 1966
Missing: Jane Beaumont (9), Arnna Beaumont (7), Grant Beaumont (4)

Case Summary
On 26 January 1966, siblings Jane, Arnna and Grant Beaumont travelled to Glenelg Beach in Adelaide, South Australia.
The children were expected to return home by lunchtime. They never did.
Witnesses reported seeing the three children throughout the day in the company of an unidentified fair-haired man believed to be in his late twenties or early thirties. Despite one of Australia’s largest and most extensive investigations, neither the children nor the man have ever been identified.
For almost six decades, the Beaumont children’s disappearance has remained one of Australia’s most enduring unsolved mysteries.

Investigation Highlights
📍 The children were last reliably seen at Glenelg Beach on Australia Day.
📍 Multiple witnesses reported seeing them with an unknown adult male.
📍 Jane appeared comfortable speaking with the man, suggesting he may have gained the children’s trust.
📍 Hundreds of leads and numerous suspects have been investigated over the decades.
📍 Extensive searches have never uncovered any trace of the children.

Why This Case Still Matters
The disappearance of Jane, Arnna and Grant Beaumont fundamentally changed how Australia viewed child safety.
The case sparked one of the largest missing persons investigations in Australian history and remains a benchmark for cold case investigations today.
Despite decades of renewed inquiries, excavations and suspect investigations, one question remains unanswered:

What happened to the Beaumont children?
Nearly sixty years later, their disappearance continues to fascinate investigators, historians and true crime researchers around the world.

Status: Unsolved Historical Mystery
Location: Roanoke Island, present-day North Carolina, USA
Date: 1587

Archive Summary

The disappearance of the Roanoke colonists remains one of history's oldest and most enduring mysteries.

In 1587, more than 100 English settlers established a colony on Roanoke Island under the leadership of Governor John White. Shortly after their arrival, White returned to England to gather much-needed supplies. Political conflict and war with Spain delayed his return for three years.

When he finally arrived back in 1590, the settlement had been completely abandoned.

There were no bodies, no signs of a struggle, and no clear evidence of what had become of the colonists. The only clue left behind was the word "CROATOAN" carved into a wooden palisade and the letters "CRO" etched into a nearby tree.

For over four centuries, historians, archaeologists and researchers have debated the fate of the Lost Colony. Did the settlers integrate with local Indigenous communities? Were they victims of disease, starvation or conflict? Or does the truth lie somewhere in the archaeological evidence still being uncovered today?

This Investigation Covers

• The English attempts to colonise Roanoke
• The establishment of the 1587 settlement
• John White's delayed return
• The disappearance of the colonists
• The meaning of "CROATOAN"
• Archaeological discoveries
• Leading historical theories
• Why the mystery continues to fascinate researchers

Discussion

What do you believe happened to the Lost Colony of Roanoke?

Do you think the colonists successfully integrated with the Croatoan people, or is another explanation more convincing? If you've come across evidence, research or theories that deserve attention, I'd love to hear them.

Status: Unsolved
Location: Hinterkaifeck Farm, Bavaria, Germany
Date: 31 March – 4 April 1922
Victims: 6

Case Summary

On the evening of 31 March 1922, six people were murdered on the isolated Hinterkaifeck farm in Bavaria, Germany.

The victims included Andreas and Cäzilia Gruber, their widowed daughter Viktoria, her two young children Cäzilia and Josef, and the family's maid, Maria Baumgartner.

What transformed the murders from a tragic crime into one of history's greatest mysteries was what happened afterwards.

Evidence suggested the killer remained on the farm for several days after the murders. Livestock were fed, meals appeared to have been prepared, and smoke continued to rise from the chimney. When neighbours finally became concerned and entered the property on 4 April, they discovered one of the most disturbing crime scenes in modern history.

More than a century later, despite countless investigations and numerous suspects, the Hinterkaifeck murders remain officially unsolved.

Investigation Highlights

• 📍 Six victims discovered across the farmhouse and barn.
• 📍 Strange footprints in the snow leading to the farm but not away.
• 📍 Reports of unexplained noises from the attic before the murders.
• 📍 A missing newspaper appearing before the attack.
• 📍 The killer is believed to have remained at the farm for several days.
• 📍 No one has ever been convicted.

Why This Case Still Matters

The Hinterkaifeck murders continue to fascinate historians and true crime researchers because so many questions remain unanswered.

Who was responsible?

Were the murders carefully planned, or did events unfold unexpectedly?

Why did the killer stay behind after the murders?

And was someone secretly living on the farm before the attack?

More than 100 years later, there is still no definitive answer.
