20 Criminal Heists Authorities Still Haven’t Solved


20 Criminal Heists Authorities Still Haven’t Solved


The Great Escapes

While movies make bank robberies look like high-stakes ballets, real-life heists often leave behind more questions than answers. Even with modern forensics and relentless investigators, some criminals simply vanish into the night with millions in tow, leaving only empty frames or cold vaults. You might think it's impossible to get away with a massive score in this day and age, but history is full of clever thieves who outsmarted everyone. We're going to dive into twenty of the most audacious capers where the culprits—and often the loot—remain totally off the radar.

1. The Isabella Stewart Gardner Museum Mystery

Back in 1990, two men dressed as Boston police officers walked right into this museum and walked out with thirteen priceless masterpieces. They spent over an hour cutting paintings like Rembrandt’s The Storm on the Sea of Galilee out of their frames while the actual guards were tied up in the basement. Despite a ten-million-dollar reward and countless tips, the empty frames still hang on the walls as a ghostly reminder of the world’s biggest unsolved art theft.

2. The Legend of D.B. Cooper

In 1971, a man wearing a dark suit hijacked a Boeing 727, demanded two hundred thousand dollars, and then parachuted into a freezing thunderstorm over Washington state. No one ever found him or the vast majority of the cash, though a young boy did dig up a small bundle of decaying bills years later. He’s become a folk hero of sorts because he pulled off the only unsolved skyjacking in commercial aviation history and then simply evaporated.

3. The Antwerp Diamond Center Job

A group of Italian thieves known as the "School of Turin" spent years planning a raid on one of the most secure vaults on the planet. They managed to bypass infrared sensors, doppler radar, and a magnetic seal to make off with over a hundred million dollars in loose diamonds and gold. While the leader was eventually caught due to some discarded trash, most of the loot was never recovered, and his accomplices remain largely a mystery.

4. The 300 Million Yen Robbery

On a rainy day in Tokyo in 1968, a man on a police motorcycle pulled over a bank transport car and told the driver the vehicle was about to explode. When smoke began pouring from the car, the bank employees fled, and the "officer" simply hopped in and drove away with a literal fortune in year-end bonuses. Even though the police had over a hundred pieces of evidence, including the motorcycle, they never caught the guy who turned a fake bomb threat into a massive payday.

5. The Tucker Cross Disappearance

A diver named Teddy Tucker discovered a stunning gold and emerald cross in a 16th-century shipwreck off the coast of Bermuda in 1955. Years later, just as the cross was about to be displayed for Queen Elizabeth II, someone realized the original had been swapped for a cheap plastic replica. The genuine treasure, considered a priceless piece of maritime history, hasn't been seen since the moment it was stolen from its "secure" museum case.

6. The Great Brink’s Robbery

Eleven men wearing Halloween masks and chauffeur caps pulled off the "crime of the century" in 1950 by infiltrating a secure armored car depot in Boston. They made off with over two million dollars in cash and checks, which was a staggering amount for the time. While some members were eventually caught right before the statute of limitations expired, a huge chunk of the money stayed missing, and the heist's legendary status remained intact.

7. The Plymouth Mail Truck Heist

In 1962, a group of robbers dressed as police officers detoured a mail truck on a dark Massachusetts highway and stole one and a half million dollars. They were so organized that they even had a "scout" car and a getaway vehicle waiting in the woods. You’d think someone would’ve talked eventually, but the culprits were never convicted, and the cash seems to have been laundered perfectly into the local economy.

8. The Banco Central Tunnel Raid

Criminals in Brazil spent three months digging a two hundred and fifty foot tunnel from a rented house directly into a bank vault in Fortaleza. They even installed lighting and air conditioning in the tunnel to make the work more comfortable while they hauled away tons of currency. Although some suspects were arrested later, more than half of the nearly seventy million dollars stolen remains unaccounted for to this day.

9. The Harry Winston Store Robbery

Four men, some dressed as women in wigs and heels, walked into a high-end Paris jewelry store in 2008 and cleared out almost every display case. They knew exactly where the "hidden" safes were, which suggests they had some serious inside information or spent months scouting the place. They made off with over a hundred million dollars in jewels, and while some arrests were made, the bulk of the sparkling inventory is still out there somewhere.

10. The Iraq Central Bank Withdrawal

Just hours before the 2003 invasion of Iraq began, nearly one billion dollars was loaded onto trucks and driven away from the central bank. It wasn't a stealthy midnight raid; it was a massive operation involving several large vehicles and a formal letter of authorization. While some of the cash was found hidden in palace walls later, hundreds of millions of dollars essentially vanished during the chaos of the war.

11. The United California Bank Blasting

In 1972, a crew used dynamite to blow a hole through the roof of a bank vault in Laguna Niguel, netting them an estimated thirty million dollars. They were so professional that they even disarmed the alarm system with a specialized foam that silenced the sensors. The FBI eventually linked the job to a professional crew from Ohio, but many of the details—and much of the money—stayed buried with the thieves.

12. The Carlton Hotel Jewel Theft

A lone gunman wearing a bandana walked into a jewelry exhibition at the Carlton Hotel in Cannes and walked out with a suitcase full of diamonds. The heist took less than a minute, and the thief didn't even have to fire a single shot to secure over a hundred million dollars in loot. Since the hotel was the setting for a famous Hitchcock movie about a jewel thief, life really did end up imitating art in the most expensive way possible.

13. The Montreal Museum of Fine Arts Raid

Three armed men climbed down a rope through a skylight in 1972 and made off with a collection of rare paintings, including a Rembrandt landscape. They originally wanted more but were interrupted by a tripped alarm, so they grabbed what they could and fled into the night. Despite the high profile of the stolen art, including works by Gainsborough and Corot, the pieces haven't surfaced on the black market in over fifty years.

14. The Green Vault Diamond Heist

In 2019, thieves set fire to an electrical box to knock out the streetlights before breaking into a museum in Dresden, Germany. They smashed through glass cases with axes and snatched up historic diamonds worth over a billion dollars in just a few minutes. While some members of a notorious crime family were later arrested, many of the world's most famous jewels are still missing from the royal collection.

15. The British Bank of the Middle East

During the Lebanese Civil War in 1976, a group of militants spent two days blasting through a wall shared with a Catholic church to reach a bank vault. They walked away with dozens of safe deposit boxes filled with gold bullion, jewels, and multiple currencies. The estimated haul was so large that it actually set a world record at the time, yet the identities of the robbers remain a subject of intense debate.

16. The Knightsbridge Security Deposit Robbery

An Italian playboy named Valerio Viccei led a team that pretended to be customers wanting to rent a safe deposit box in London. Once they were inside the vault, they drew guns, tied up the guards, and spent hours pryng open boxes to find millions in cash and jewels. Viccei was eventually caught because he returned to England to retrieve his favorite Ferrari, but most of the accomplices and the loot stayed well out of reach.

17. The Irish Crown Jewels Theft

In 1907, someone managed to steal the jeweled regalia of the Order of St. Patrick from a safe inside Dublin Castle. There were no signs of a break-in, which led authorities to believe it was an inside job involving someone with a key. To this day, the jewels have never been recovered, and the mystery has fueled over a century of conspiracy theories regarding the Irish aristocracy.

18. The Heathrow Airport Gold Heist

A group of six men broke into a warehouse at Heathrow in 1983, expecting to find a modest amount of cash but discovering three tons of gold bullion instead. They spent hours loading the gold into a van and then disappeared, sparking a massive international manhunt. While the police eventually tracked down some of the crew, a large portion of the gold was reportedly melted down and sold, meaning it's likely circulating as jewelry today.

19. The Northern Bank Robbery

In 2004, a gang in Belfast kidnapped the families of two bank officials to force them to help loot their own workplace. They made off with over twenty-six million pounds in what was one of the most organized and cold-blooded heists in UK history. Because the robbers took mostly unrecorded notes, the money was incredibly hard to track, and the case remains a massive "what if" for investigators.

20. The Graff Diamonds Daylight Raid

Two men wearing high-end prosthetic makeup to look older walked into a London jewelry shop in 2009 and stole nearly seventy million dollars worth of gems. They used a series of getaway cars and even fired shots in the air to distract the public during their escape. Even though the police eventually arrested the main players, the diamonds themselves vanished into a global network that has never been cracked.
