The idea of a "perfect crime" has tantalized authors and criminals alike for decades. While the goal of almost every crime, from bank robbery to murder, is always to get away with it, very few criminals actually succeed. Most "unsolvable crimes" are eventually figured out, because most criminals simply aren't smart enough to not leave clues behind. Or they get away with one thing, but are too greedy to pull off only one heist, and trip up when they try something else.
But a few times in history, everything has lined up perfectly for a criminal to get away with something and not get caught. Sometimes it's skill, sometimes it's the incompetence of investigators, and sometimes it's just dumb luck that lets them ride off into the sunset with sacks of cash, art or jewels. Each one of these crimes tells a story - criminals one step ahead of the law, disappearances, epic shootouts, one guy who really, truly deserved what happened to him, and huge amounts of money that have simply gone into the wind.
Here are some of the most perfect crimes and cases of undetected crime committed in the last century - robberies and murders with no trace of who did them, or where the spoils went.
The Most Perfect Crimes Ever Committed,
Ken McElroy
In 1981, Ken Rex McElroy, a bully who had terrorized the citizens of tiny Skidmore, MO for years, was shot dead by at least two people in the middle of the day, in full view of dozens of people. McElroy's slate of crimes was massive, including dozens of felony charges for robbery, assault, attempted murder, child molestation, cattle rustling, and finally, shooting a man in the neck with a shotgun.
Unfortunately for the townspeople, McElroy had always been able to get off and go right back to bullying the town. So when police began investigating his murder, not a single person came forward to give evidence. They simply had had enough of him and his crimes. While McElroy’s widow identified a man she thought was one of the shooters, nobody was willing to corroborate her testimony, and the case went unsolved – with the town breathing a sigh of relief that a man who had brutalized them for years was gone.
Jimmy Hoffa's Murder
Famed labor leader Jimmy Hoffa had a lot of clout, and a lot of enemies. Those enemies were closing in on the embattled president of the International Brotherhood of Teamsters, with the FBI suspecting him of pilfering a staggering amount from the union’s pension fund. Two weeks after the investigation became public, Hoffa vanished leaving a Detroit restaurant with several known Mafia members.
After seven years of dead ends, tight lips, and go-nowhere leads, the FBI declared Hoffa dead. Despite rumors of his body being buried everywhere from a horse farm in rural Michigan to under the grass at Giants Stadium, no trace of the man, or his killer, has ever been found.
The Twin Jewel Thieves
On February 25, 2009, three masked robbers used a rope ladder to break into the second largest department store in Europe, Kaufhaus Des Westens (KaDeWe to locals), and stole $7 million worth of diamonds. In their haste to get away they left behind a single glove. What should have been a slam-dunk prosecution turned into a fiasco thanks to a loophole in German law, because the DNA found on the glove matched TWO people.
The culprits were identical twins, identified only as Hassan and Abbas O. German law requires that each person involved in a crime be individually convicted and because the twins’ DNA was so similar, it couldn’t be determined which one was actually involved in the crime. They were both set free, and the third robber was never identified.
Isabella Stewart Gardner Museum Heist
On St. Patrick's Day 1990, two men dressed as police officers walked into Boston's Isabella Stewart Gardner Museum, duct-taped two unarmed guards and crudely cut 13 paintings out of their frames. The value of the works, including paintings by Rembrandt, Degas, and Manet, totaled over $300 million – and none have ever been recovered. The empty frames still hang in the museum as a reminder of what was stolen.
The 300 Million Yen Robbery
On December 10, 1968, a Tokyo-based Nihon Shintaku Ginko Bank car that was transporting Toshiba employee bonuses amounting to 300 million Yen (worth $817,000 at the time), was pulled over by a policeman on a motorcycle. The cop warned the four passengers in the car that there was a bomb planted underneath, and they quickly vacated the vehicle, leaving the uniformed patrolman to crawl under the car. Moments later, smoke and flames poured out of the bottom, causing the occupants to run for it – whereby the cop jumped in the bank car and drove off.
The ensuing investigation involved 120 pieces of evidence, 110,000 suspects, and 170,000 police detectives. But it was all in vain, as the phony cop was never caught. In 1975, the statute of limitations ended and in 1988 all charges were dropped, but the culprit still never came forward.
Theft of the Patiata Necklace
The Patiala Necklace was designed by the legendary house of Cartier in 1928 as a gift for the Maharaja Sir Bhupinder Singh of India. And what a gift it was, with five rows of platinum chains encrusted with 2,930 diamonds and Burmese rubies. The centerpiece was the famed DeBeers Diamond, a 234.6-carat yellow bauble that was the seventh largest in the world at the time. Such a valuable piece was a tempting target for theft, and sure enough, the necklace disappeared in 1948 after being worn by Bhupinder’s son, Maharaja Yadavindra Singh.
While the necklace itself was finally found in London 50 years later, the jewels, including the DeBeers diamond, were long gone. Rumor has it that the stones were sold off by the Maharaja’s family, and the DeBeers itself popped up in 1982, on the auction block at Sotheby’s. It was bought by an unknown buyer for a little over $3 million, and hasn’t been seen since. The other stones have never turned up.
Operation Goral
The Polish resistance to Nazi rule needed large amounts of cash currency to operate. So when informants learned of regular movements of Polish currency to a German-controlled bank in Krakow, the resistance hatched a plan to rob it. Over a year of plotting, as well as information from sympathizers in the bank, allowed them to pull off an astonishingly fast robbery, looting the equivalent of $1 million ($20 million today) and killing between six and nine German soldiers, with no loss of life on their side.
German authorities had no idea who pulled off the heist, and since they didn’t know if it was the resistance or common criminals, they didn’t take reprisals against the population of Krakow.
DB Cooper's Hijacking
On Thanksgiving Eve, 1971, a hijacker who called himself Dan Cooper boarded a Northwest Airlines flight in Portland, OR, wearing a suit and tie. Once the flight was in the air, he ordered a drink and passed a note to the stewardess saying, "I have a bomb in my briefcase. You are being hijacked." He demanded $200,000 in unmarked bills, two parachutes and a fuel truck.
When the plane landed in Seattle, Cooper exchanged the hostages on the plane for the money and parachutes, and ordered the plane to take off again. 30 minutes into the flight, Cooper deployed the back stairs of the airplane and jumped out. An exhaustive investigation turned up no clue as to where Cooper (who was misidentified as "DB Cooper" in a local news story) or the money wound up, though a small amount was found near the Columbia River some years later.
Antwerp Diamond Center Robbery
It was the greatest diamond heist of all time. A gang of Italian thieves broke into an underground safe at the Antwerp Diamond Center and made off with an astonishing haul of over $100 million (some sources put the number closer to $150 million) in loose diamonds, gold, and other gems. The ringleader was arrested and given a 10 year prison term, but some of the crew escaped, with the diamonds never being found.
The jailed ringleader claims the haul was only about $10 million worth of diamonds, that he’d been hired to rob the vault as part of an insurance fraud scheme, and that he had nothing to do with the actual theft. Eventually, some of the gems were found in a vault in Italy – only to be stolen again by unknown thieves.
Dar Es Salaam Bank Robbery
On July 12, 2007, the Dar Es Salaam bank, one of the largest in Baghdad, was robbed by Iraqi security guards working the overnight shift. When the bank’s employees came into work that morning, they found the front door open, the bank vault doors ajar and nearly $300 million in cash gone.
Much of the money was eventually recovered, but the guards themselves were never found - it's thought they vanished into one of the many sectarian militias in the city.
