Creepy Unsolved Mysteries - From unsolved murders to unidentified people to unexplained supernatural events, what are some of the creepiest unsolved mysteries you've ever heard of?

  • 🔧 At about Midnight EST I am going to completely fuck up the site trying to fix something.
Paraquat murders

In Japan, in 1985, there was a rash of indiscriminate poisonings using the deadly herbicide, paraquat. The culprit targeted a brand of soda that was having a "buy one, get one free" campaign. They would put a tainted bottle inside the dispenser of a vending machine so when you purchased the drink, you'd think you got the extra soda for free. A total of 35 people were poisoned and 12 died. The poisonings stopped once police and the vending machine companies plastered the soda and machines with warnings to check the tamper seal before drinking. It is completely unknown who did it or why.
Reminds me of the Tylenol poisoning that happened in the Chicagoland suburbs in 1982. Some fuckass poisoned a ton of Tylenol with cyanide and a bunch of random people all over the burbs ended up dying as a result, and nobody's totally sure who did it or why. Was there just an underground poisoning ring going on in the 80s or what??

I doubt I'm talking about the same exact situation but, wasn't there someone who did something very very similar to kill an ex wife? or Someone known to them? Then then attempted to cover it up by poisoning random people. The killer figured if the police thought it was some random maniac killing indiscriminately they would overlook them targeting and poisoning someone known to them. The "beltway sniper" did the same thing IIRC, shooting random people to disguise the targeted killing the ex wife.

I think the problem was that it was a lot of Tylenol poisoned for one person to be doing it to cover up a crime. It was poisoned at a source then shipped out to a large area.
 
Michigan's Unidentified Chunks of Sewer-Flesh:

From 2012-2013, there were at least three cases of human flesh being found in the sewage system of Macomb County, Michigan. The first time happened in August of 2012 in Sterling Heights, and included 10-12+* pieces of fat, muscle tissue, and skin that also featured sections of the victim's tattoo. The victim themself was an unidentified Caucasian, obese female who was estimated to have been between 15-20 years-old when she was killed, and was not in missing person's data base either. Nothing else is known.

The second time was in December of the same year around the town of Warren, and in this instance the chunks were neatly cut cubes about four inches big that included the fat, skin, and muscle tissue just like the previous case, but no identifying marks, or tattoos were present. They were found about five-seven** miles from where the other pieces had been located, and despite the similarities, the remains were determined to have come from a different victim who was also not in the missing person's data base. Yet again, nothing else is known.

The third time happened in September of 2013, and were discovered once again in Sterling Heights. The pieces were again similar in size, and style to the previous ones although they again contained no identifying marks, or tattoos like the first ones did. The victim was confirmed to have been again Caucasian, and possibly also have dark hair, but other than that just like the two other instances nothing pertaining to the victim has been released, or is known.

The two most common theories are that it's either the workings of a serial killer, or improperly disposed of medical waste from a lab, but whatever it is, the fact remains that despite ten years having passed, no leads, suspects, or identifications have ever occurred.

*Articles vary on how many pieces were actually found.
**Articles vary on the exact distance of the location.
Was there just an underground poisoning ring going on in the 80s or what??
It's never been clear as to why. Theories range from it just being some guy fucking around to the government deliberately doing it to see how a potential attack like this would pan out to a rogue employee trying to prove a point, or get back at the company to a genuine accidental contamination, etc.

Personally, I have no clue.

I legitimately hadn't even considered the government did it, and now I can't think of anything else.

There also was the dude that handed out cyanide pixie sticks becuase he wanted to kill his son and figured it wouldnt get him caught if he poisoned and killed a bunch of other kids too.

I remember the tylonel thing though they were unsure where they were tampered with in the line as well if it was before it went ot store or after.

Reminds me of all the human feet being routinely found in the Salish Sea in the Pacific Northwest. Since 2007, at least 23 feet have been found on the shore, all still encased in a shoe and some with a bit of leg still attached. The most common belief is that over the years, various people have died by suicide or in accidents around there since it's a pretty large area. When their body begins to decay, their ankle weakens and the buoyancy of their shoes, usually sneakers, causes the foot to rise to the surface and get swept away. A large percentage of the feet found have been positively identified to various missing people and known suicides, though some are still unidentified.

Authorities don't suspect foul play in any of the cases but admit that even given the geography of the surrounding area, this is a very abnormal amount of human feet washing up. And since they're only pretty well decomposed feet in a lot of cases, who's to say what even the cause of death is. Some of them are no-brainer accidents from people who went missing while hiking or jumped from a bridge, but among all those mysterious feet I have to wonder if there aren't a few murders mixed in.

Your mystery sewer flesh is a lot creepier. The medical waste theory is tempting especially since it's known the first victim was obese and some kind of surgery makes sense there. I'm not sure if that flesh containing a detailed tattoo is more evidence for or against a kind of surgery. If it was an elective procedure, naturally you won't want to ruin a tattoo. It also seems like if it was someone illegally disposing of medical waste, there would be a lot more of it, from either a medical practice or a medical waste disposal service. Also baffling is why they kept finding more of it after the first discovery. If I was dumping medical waste or killing people I would stop using the same tactics once the remains were found the first time. And of course if it is a serial killer, where are the bodies?

Strange story.

I've heard of this one, and the most compelling theory I've seen is that the unidentified feet are from tsunami victims-specifically ones from either the 2004 Indian Ocean one, or the 2011 Japanese one. The brand styles would match up from the time periods as would the amount of time it would take for them to drift all the way over there.

Either way, it's creepy, and sad as hell.

The problem I have with the government doing it, either in this case or all the various indiscriminate poisonings out there that have yet to be solved, is why would they use a lethal chemical when they could use something non-lethal but severe enough that the victims will be hospitalized, ensuring accurate statistics gathering? Potassium cyanide is extremely lethal so there's no ambiguity in the poisoner's mind about what will happen. I won't even appeal to morality here and say "surely the government wouldn't kill its own citizens for data" I'll just say "why kill them when you can just make them very sick?" You get the same information and there will be a hell of a lot less scrutiny on the poisoning.

A homicidal poisoner who just wants to kill people makes a lot more sense than a glow-op.
 
Came across this in my YouTube recommendations:

Definitely odd and creepy. Anyone else ever look into this?

Weird one. I like commentor @RuthlessMojo's analysis the best: the two young men were mixed up with drug trafficking, fucked up and angered their superiors, and were taken out to that remote trailhead and killed, with the evidence burned and scattered and their bodies disposed of elsewhere. Several other men went missing in that part of British Columbia during the same period, which just makes the mystery that much more sinister.

This is weird, I randomly watched a different documentary on the Pemberton incident two days ago. Initially I thought some form of illegal pornography trade or hacking when it was mentioned that Isawaa was a programmer working on his own game, but as it went on it was clear that the motive was nothing so exotic. Especially the whole business with Iswaa's storage unit, as it turns out that a lot of drugs move in and out of those facilities in North America. The documentary also covered the disappearance of another man the same age around the same time, and how they could be linked. I'll see if can dig it up.

Edit: disregard this, it turns out that the documentary @Cpl. Long Dong Silver posted is the exact same one I watched, I just listened initially so I didn't recognise the graphics.

There also was the dude that handed out cyanide pixie sticks becuase he wanted to kill his son and figured it wouldnt get him caught if he poisoned and killed a bunch of other kids too.
According to wikipaedo:

O'Bryan's last words were, "What is about to transpire in a few moments is wrong! However, we as human beings do make mistakes and errors. This execution is one of those wrongs yet doesn’t mean our whole system of justice is wrong. Therefore, I would forgive all who have taken part in any way in my death.

Fucking narcs.

In the late 80's, there was a serial killer targeting homeless people in India. The press dubbed him the "Stoneman" because he always killed his victims with a large stone or piece of concrete. He'd simply target a homeless person who was alone and smash the poor fellow's head in. He killed 12 in Mumbai over the course of two years before suddenly stopping.
Thug life.
 
If anyone had "visiting the old Burger Chef restaurant in Indianapolis where 4 people were kidnapped then murdered back in 1978" on their bucket list, it's probably too late.


Headline calls it the site of the murders, it was not. The people were killed and left in nearby Johnson County.
 
Cool story of Mike 'Madman' Marcum


Punchline- He is alive, trying to make another machine. I doubt that any of it happened.
"Oh shit, my welder just cut space=time and sent my electrode 2 years into the future."
Reminds me about the 'Radioactive Boy Scout'. Autistic fan-boy of a technology.
Remember, time-travel isn't real, but arc-flash explosions are.
 
I was going to watch the 2018 Keli Lane documentary but then I realised that there were three episodes an hour long and that's too much work. Anyway. I've read notes instead and it turns out that everything is even more weird than it was in 2010 when she was convicted.

She taught sex ed to teenagers, but was pretty much continually pregnant for seven years. And apparently doesn't have a personality disorder. The fuck is going on in her head?
 
Here's one that's only partially unsolved, but still creepy as hell: the disappearance/murder/"dematerialization" of Marcia Moore. She was a popular astrologer, yoga teacher, and early advocate/practitioner of ketamine therapy who vanished from her Washington State home in early 1979. The investigation quickly became a shitshow because of her connections to the occult/New-Age scene and the characters therein, and is officially unsolved.

The book about the case, Dematerialized, examines all the reports from police, private investigators, and the family, and has a pretty good solution to the mystery, even though the people involved are long dead and will never face justice. (Weirdly enough, Moore's son Christopher Roof also vanished over thirty years later; his body was eventually found in the Maine wilderness but nobody can figure out how he ended up there.)
