The Astrology of Serial Killers

Sam Reynolds • 29 September 2022

Trends too poignant to ignore

When we read about the chilling exploits of serial killers like Pisces John Wayne Gacy, Sagittarius Ted Bundy, Gemini Jeffrey Dahmer, Pisces Richard Ramirez or Gemini Sam Berkowitz, it’s only natural to wonder if astrology could’ve provided insights into what contributed to their madness. The answer, in fact, is yes; but since there’s no one size that fits all in astrology, it’s impossible to pin a “serial killer” alert on any one set of signs or factors in a person’s chart. Yet there’s still something to learn from noticing trends with known serial killers.

 

If you look at the birthdates for the men named above,  you’ll notice an interesting trend that even proves true with a longer list of serial murderers as well: all their Sun signs are mutable, that is either Gemini, Virgo, Sagittarius or Pisces.

 

Mutable signs thrive on variety, versatility and a need to convert insatiable mental stimulation into real world experiences. If  those traits are combined with a troubled childhood and psychotic breaks, a killer with a prolific track record of disaster could erupt out of a once innocent, curious soul.

 

The mutable signs are unique in the Zodiac because all 4 signs are divided between two planets only: Mercury and Jupiter. Expansive Jupiter is the traditional ruler for both Sagittarius and Pisces (with Neptune being a modern co-ruler). Quick-minded Mercury is the ruler for Gemini and Virgo. Both planets signify how we roam and perceive the world. One consistent trait among serial killers is a need to roam and it’s usually matched with a unique (and damaged) perception of the world.

 

Since Mercury symbolizes how we think, you’ll often see how a set of normal-range of anxieties, thoughts and feelings can grotesquely become full blown psychoses that can be symbolized in a serial killer’s astrological chart.

 

For instance, Sagittarius Ted Bundy’s volatile Mars pairs up with a rootless, philosophical Sagittarian Moon by conjunction and opposes his aloof Uranus in Gemini. Certainly a fitting symbol for someone known as a murderous “stranger.” His Mercury and Jupiter were both in obsessive and passionate Scorpio. Another appropriate symbol for someone who could not stop thinking about his dark sexual needs and travelled far and often to fulfill them.

 

Pisces John Wayne Gacy had his Mercury in Pisces (ruled by Jupiter) and his Jupiter in Gemini (ruled by Mercury). His deadly, planetary switcheroo combined with his own repressed murderous lust found young hitchhikers and hustlers (all Mercurial archetypes) ideal victims. This same love of versatility allowed him to slip into a number of occupations, like a show salesperson, fast food restaurant owner, community volunteer, amateur clown, and his last one as a well-paid painter on death row!

 

Of course, the mutability of many serial killers doesn’t make someone with a mutable Sun sign more of a likely suspect than anyone else. After all, most serial killers are men, but that doesn’t make all men likely suspects. Yet mutability is all about following curiosity’s lead, and perhaps an astrological understanding can help a potential serial killer find a road that leads to creativity and self-knowledge rather than killing.

Over the years, I've long thought about how to describe Neptune succinctly. Of course, the nebulous planet would resist that from me and others. But when has resistance ever been a complete deterrence? Then, the other day, I thought of Neptune as a boomerang, and it resonated with me. That doesn't mean I've found a pithy way to describe every aspect of Neptune. I haven't, and that would be delusional, i.e., Neptunian. Perhaps I'm getting an image of a hunter-warrior or a sporting tool as an association with Neptune since it has moved into the sign of Mars, Aries, over the last few months. This prompted a modest dive into boomerangs, and I learned way more than I thought I knew. That may be true for you. I found this article the most helpful online. For starters, I didn't know that there were returning and non-returning boomerangs. I thought all returned. The Britannica article says, "Returning boomerangs were used only in eastern and western Australia as playthings, in tournament competition, and by hunters to imitate hawks for driving flocks of game birds into nets strung from trees. The returning boomerang is generally considered to have developed from the non-returning types, which swerve in flight." Also, boomerangs, as throwing hunting clubs, weren't just developed in Australia, as I had thought. It's a tool that has been documented as being used in ancient Egypt, by indigenous peoples of North America, and in India. However, considering the boomerangs of Aboriginal Australia, my connection with Neptune makes more sense. Both returning and non-returning boomerangs are often beautifully ornate and are used in some religious rituals, accompanied by songs and chants. This, of course, hints at the lofty, otherworldly, and artistic sense of Neptune. Neptune, as I generally describe her (I made her trans about 20 years ago), lends herself toward intuition, imagination, illumination, illusion, and, by default, delusion. However, with Neptune, things are not as they appear. What's more, there is a projection effect that eventually comes back to us, like a returning boomerang. It either comes back to us as one of the I's for Neptune that I listed above or as a delusion. Intuition is a two-fold process, though many think of it as only one-sided. You either receive an input or project an output and get something back that's clarifying or wrong. Imagination is similar but a more active cultivation of your creativity. Illumination can come from feeling a sense of union with a sense of being or wisdom that seems beyond you. Illusion can be an inaccurate projection or reception. Similar to an illusion, a delusion is a more sustained false belief or judgment. Yet, all versions of these conceptions of Neptune reveal how we're out of tune with a current reality. What's fascinating to learn about returning boomerangs is not only do they have the ability to return to the thrower when not hitting anything, but they're used more for imitation and misdirection toward another end, like driving flocks of game birds into nets. These hunters become more like magicians, and this gives us a clue more about Neptune. Another word we can use for Neptune is 'enchantment.' That's a word that's frequently on my mind because I live in the US state of New Mexico, which has been dubbed "The Land of Enchantment." The phrase is even on many of our license plates. It's doubly funny for me since Neptune is directly on my midheaven here for my relocated chart or Astro*Carto*Graphy. It can be either delightfully enchanting to meet someone or encounter something, or it can be a nightmare. I'm sure we've all had our fair share of both. But what's key, like the flick of the wrist required to throw a boomerang so it returns, is all in how we're paying attention or not. And the truth is sometimes we don't want to pay attention. We sometimes wish to stay with the enchanting dream. And that's when reality itself acts like a boomerang, sometimes hitting us, especially when it's the reality to which we're not paying attention. We often fail to realize that we're inattentive hunters who've not noticed or forgotten that the misdirection was intended for another purpose. If you have Neptune prominently in your astrological chart, or you're undergoing a Neptune transit, then it becomes doubly important to reflect on her boomerang effect. (It's also okay if you're a bit disoriented by my use of the female pronoun for a planet named for a Roman male god. I mean, that's Neptunian.) It's only when you're not paying attention that you're likely to get whacked somehow. And it's equally possible that you can use Neptune, like many Aborigines, for evocation, positive misdirection with intuition, imagination, enchantment, or fun without any harm at all. Just stay alert and attentive. Perhaps that's all Neptune truly desires of us.
