One of the most infamous serial killers in history was known as the "Zodiac Killer." Although he was never apprehended, his legacy continues to terrify. The mystery surrounding the case has fascinated generations, even though the original crimes were committed in the late '60s and early '70s!

So, what is a Zodiac Killer? Although the name of the Zodiac Killer might make you think about horoscopes, he actually got the name (and the logo he signed his letters with) from a watch brand. In the 2007 movie Zodiac, leading suspect Arthur Leigh Allen wore a Zodiac Sea Wolf Watch — and he was a Saggitarius.

In fact, you can find the horoscope (and criminal record) of almost anybody on Instant Checkmate. Give it a spin! You might be horo-fied to see the results.

Scary Zodiac Killer Sign

There have been many suspects in the Zodiac killings, but the real killer was never caught. Along with Arthur Leigh Allen, Earl Van Best Jr. (Cancer) was a leading suspect.

According to some popular astrologists, some star signs are more likely to commit crimes than others. So, what are the Zodiac signs most likely to end up behind bars? Discover all the deadly traits of your astrological sign in our infographic, and get the full story in the list below!

Zodiac Signs In Order

Of the horoscope signs, the least dangerous is the Gemini! If a Gemini is going to engage in crime, it’s probably centered around fraud or stealing. That said, prolific serial killer, Jeffrey Dahmer was a Gemini. Negative traits of a Gemini include anxiety, shallowness, and inconsistency. But overall they’re not that dangerous!

Evil Twin: John Collins, David Berkowitz, Jeffrey Dahmer, Danny Rolling, Peter Sutcliffe, Wayne Williams

The Aquarian is fairly good-natured until they’re a victim of wrongdoing. When it comes to revenge crimes, Aquarians lead the pack! The clever and charismatic Aquarius would make a good hustler or hacker. Manipulation is their dark horoscope trait!

Cup Half Empty: Gary Ridgway, Kim Jong Il, Jerry Brudas, Derrick Todd Lee

Watch out for the lion’s roar! Leos are notoriously passionate and feisty. Although this is mostly a positive trait, Leos can go awry if they have a psychotic temperament. The lion loves to be the center of attention, and as a fire sign, they also have a vicious temper. Leos might get sucked into criminal activity for the fame!

Rogue Lions: Benito Mussolini, Grigori Rasputin, Elizabeth Báthory, Myra Hindley, Anthony Sowell

Scorpios can be jealous and aggressive — a terrible combination in the wrong circumstances! If a Scorpio goes to the dark side, they might find work as an assassin! Scorpios are also considered the most sadistic sign, and an evil Scorpio has no issue with murder. Scorpios are very cunning. They might not commit the evil act themselves, but don’t be surprised to find them pulling all the strings out of sight!

Scary Scorpions: Charles Manson, Katherine Knight, Belle Gunness, Carl Eugene Watts

Beware of the fish which swims in two directions! They might be concealing a hidden dark side. Pisces are most likely to be involved in crimes which hurt themselves — i.e. drug abuse. But the hot tempered Pisces can also become very dangerous if they happen to be crazy! Serial killers are often Pisceans.

Freaky Fish: Osama Bin Laden, John Wayne Gacy, Richard Ramirez, Dennis Rader, Raymond Fernandez

The Libra is the sign for the balance of justice and values. A Libran doesn’t easily break the law. If they do, they are more inclined to get involved with a ponzi scheme or banking scandal. The evil Libran will likely hide behind a large organization to commit their crimes. If they go rogue, expect them to be on the run and heavily armed!

Tilted Scales: Lee Harvey Oswald, Andrei Chikatilo, Jesse Helms, Angelo Buono, Jr.

Virgos are clever, but they also have a criminal streak. A Virgo might be more inclined to get involved with hacking, burglary, or other types of stealing. Unlike other star signs, Virgos treasure order and neatness, so don’t expect them to leave a messy trail if they commit a crime!

Not-So-Virginal: Ed Gein, Ivan The Terrible, Rodney Alcala, Richard Angelo

Capricorns are the most likely to be all-around crooks. From petty crimes to sadistic acts, the criminal Capricorn can be very dangerous! On the plus side, Capricorns aren’t very good at covering their tracks. This makes them the easiest sign to bust for wrongdoing.

Mean Goats: Harold Shipman, Ian Brady, Dean Corll

The stubborn ram doesn’t like being told what to do. They might seek an illegal career to avoid the rat race. Ariens hate to have their authority challenged. If you try to boss the ram around, you might end up getting the horns! Although the evil Arien is most likely to become a hired gun, he could become power hungry which can lead them to spin a web of illegal activity!

Rotten Rams: Adolph Hitler, Robert Durst, Paul John Knowles, Keith Jespersen

A sinister Sagittarian can be volatile and unforgiving. If the wrath of the centaur is summoned, watch out! They can be extremely harsh. That said, in most cases Sagittarians are reluctant to hurt others and are more likely to be arrested for theft — if you can catch them! The slippery centaur is notoriously hard to pin down. Just ask serial killer Ted Bundy, who escaped from prison twice!

Broken Arrows: Ted Bundy, Joseph Stalin, Pablo Escobar, Edmund Kemper

Taureans are very temperamental. The possessive and stubborn bull can fly into a rage easily, making them a very risky star sign. Clever but solitary, the terrible Taurus prefers money laundering or financial crimes to avoid having to engage with others. The Taurean is a natural leader, but if they go in the wrong direction, they can easily end up as a ferocious dictator. A Taurean tyrant can be a blood-thirsty megalomaniac, hell-bent on world domination. Hitler was born on the last day of Aries. Depending on the time he was born, he could have been a Taurus!

Raging Bulls: Pol Pot, Saddam Hussein, Martha Beck, Albert Fish, H.H. Holmes

Cancerians are the most deadly horoscope in the zodiac! Out of all the star signs, they are arrested the most. Mental instability is a negative trait of the Cancer sign, and this can make them likely to offend repeatedly. Crimes of passion are frequent in the house of Cancer. If the creepy crab gets a taste for killing, they’re likely to strike again and leave distinguishing marks on their victims.

Crazy Crabs: Jodi Arias, Bill Cosby, OJ Simpson

Earl Van Best Jr. looked almost identical to police sketches of the Zodiac Killer, and evidence outlined in the book The Most Dangerous Animal made a compelling case against him. His fingerprints and handwriting closely matched that of the mysterious killer. It turns out he was a Cancer, the most dangerous sign in the zodiac!

Many serial killers and all-around psychopaths looked like totally normal people ... until it was too late. Look up almost anyone with an InstantCheckmate background search. You could find criminal records, arrest history, social media profiles, and much more. What will you find?
