When someone is murdered and no one is held accountable, the silence that follows can be louder than the crime itself. These five unsolved murder cases, some strange, others deeply chilling, remain mysteries to this day. With unanswered questions, strange clues, and haunting details, they continue to baffle families, detectives, and true crime enthusiasts around the world.
Let’s dive into the disturbing details of each.
1. The Atlas Vampire-A Blood-Drained Crime Scene
In 1932, in a quiet neighborhood of Stockholm called Atlas, something dark unfolded.
Lilly Lindström, a 32-year-old sex worker, was found dead in her small apartment. She had been bludgeoned to death with a blunt object and lay face down on her bed, naked, her clothes neatly folded nearby.
But the most horrifying part? Her body had been completely drained of blood.
Police found a blood-soaked ladle in the room, suggesting the killer may have drunk her blood. Despite interviewing her regular clients, no arrests were made. With no DNA technology at the time, the case quickly went cold. Today, it remains one of Sweden’s most bizarre murder mysteries, haunting in both its brutality and its vampire-like implications.
2. The Frankfurt Slasher – A Serial Killer Hiding in Plain Sight?
Between 1985 and 1990, the Frankfurt neighborhood in Philadelphia lived in fear of an unidentified serial killer who preyed on women, mainly those who frequented a local bar called Goldie’s.
Each victim had been stabbed dozens of times, sexually assaulted, and left in disturbing conditions. Police eventually arrested Leonard Christopher, a seafood store employee, based on circumstantial evidence. But many believed he was innocent, especially since the killings didn’t stop after his arrest.
Another murder eerily similar in method occurred after Christopher was in custody. To this day, the real identity of the Frankfurt Slasher remains a mystery, raising questions about wrongful conviction and whether the real killer ever walked free.
3. Ricky McCormick – A Man, A Murder, and an Unbreakable Code
When Ricky McCormick’s body was found in a Missouri cornfield in 1999, it was so decomposed after just three days that police suspected foul play.
There were no obvious signs of trauma. No suspects. No motive.
But what caught investigators’ attention were two crumpled pieces of paper in his pockets, filled with strange coded messages. Despite being shared with the FBI and cryptography experts, the code remains unsolved to this day.
Was it a personal note? Drug-related instructions? A dying message? The FBI considers it one of the top three unbroken codes in American history, right alongside the Zodiac Killer’s cryptic messages.
4. The Dupont de Ligonnès Family – Murder or Elaborate Escape?
In 2011, police made a horrifying discovery beneath the patio of a home in Nantes, France: the bodies of five family members, Agnes and her four children. Each had been drugged, shot, and buried in a shallow grave, alongside the family dogs.
Missing? The father, Xavier Dupont de Ligonnès.
Before the murders, Xavier had emptied the family’s accounts, pulled the children from school, and told friends they were moving to Australia. He was last seen in a hotel, and despite an international manhunt, he has never been found.
In a bizarre twist, someone sent a postcard in 2015 claiming, “I’m still alive.” Was it him? Or a hoax? Either way, the case remains one of France’s most haunting mysteries.

5. Keith Warren – Suicide or Something More Sinister?
In 1986, 19-year-old Keith Warren was found hanging from a tree in Maryland. Authorities ruled it a suicide and quickly had his body embalmed, without conducting an autopsy.
But things didn’t add up.
His clothes didn’t match what his mother saw him wearing earlier that day. His shoes weren’t the ones returned by the police. Years later, an anonymous envelope arrived on his mother’s doorstep containing graphic crime scene photos. A private pathologist later found toxic chemicals in Keith’s system, suggesting he was dead before he was hanged.
Then, a cryptic note appeared:
Don’t worry. Mark Finley will be next.
Mark was Keith’s friend. He died shortly afterward under suspicious circumstances.
The case is officially closed, but Keith’s family and many others believe the truth was never revealed.
Final Thoughts
Murder is horrific. But murder without answers? That leaves behind a different kind of pain, one that lingers for decades.
From cryptic codes to mass killings, these cases are reminders that some killers walk free, some puzzles remain unsolved, and justice isn’t always guaranteed.
