The woman who recorded other people’s voices on her sleep app
Here’s how she describes what happened:
“This night I was sleeping in my bed – my 3 year old was with me that night as he is scared of the dark. It was just the two of us in the whole house. The next night I decided to go through and delete my recordings and saw this particular record. In it, you can here some clicks that start to get louder over the course of the recording. Eventually you can hear me say “What are you doing??” and immediately after there is a deep voice that says “Nothing”. The clicks become very loud at that point and at the very end of the recording you hear the same voice say “That’s them” (I think?). I am pretty creeped out by this. I don’t remember being awake that night. The only plausible explanation is that I answered my own sleeping talking but the voice doesn’t even sound like me or something I could emulate. It definitely doesn’t sound like a voice my preschooler could emulate, either. I have no idea what the clicks could be. I keep a fan going at night for white noise but the clicks sounds like they’re coming from right near my phone (which is placed right by me on my bedside table). I want to say that I’ve picked up the clicks a few times on recordings before but deleted them thinking it was nothing – this is the first time I’ve ever heard anything, though.”
Here is the audio of the recording. The woman has since moved to a new house, but one Redditer who followed up with the story said:
“I actually private messaged with the OP of the sleep app story. She was happy to say that things were going well in their new home, and her son was doing well. However, if you look at the more recently dated comments after the story was posted, OP says her son had started asking where “Ho” was and seeing “the black guy with no face.” OP and I exchanged some PMs about a year after their original post to discuss what could be going on, and apparently “Ho” followed them to their new home.”
UVB-76
Also known as “The Buzzer”, UVB-76 is a radio signal of unknown origin. No one knows what it’s purpose is or why it’s happening. They suspect it may be of Russian origin. Here’s what it sounds like:
Dutroux
“Last one: a somewhat bigger mystery, but truly terrifying. Dutroux is a well known Belgian child abuser that was caught in the 90’s. It turns out the circle of abuse is much bigger and influential than one can imagine. This is a very long and well documented read about how the investigation into child abuse is being hampered by government, police, upper class figures, etc. It takes a strong stomach to digest the witness accounts (highly nsfw) and a strong stomach to digest the injustice.” — IamScuzzlebut
The murder of Mark Kilroy

He was taken by his abductors to a ranch where he was murdered in a human sacrifice ritual. Kilroy was killed with a machete blow and then had his brain removed and boiled in a pot. His killers then inserted a wire through his backbone, chopped off his legs, and buried him at the ranch along with 14 other people who had been killed there before him.
Jodine Serrin
Serrin lived on her own, but depended on her family for help due to her mental challenges. Late in the evening of Valentine’s Day 2007, Jodine’s parents went to the condo they had purchased on Swallow Lane for their daughter and walked in on what they thought was an awkward situation. Art Serrin went to find his daughter in her bedroom, and saw a man having sex with her.
According to a 10News report, Serrin told the man to get dressed and then he and his wife, Lois, went to wait for what they expected to be an embarrassed couple to join them in the kitchen. After several minutes, Serrin returned to the bedroom and found his daughter murdered, having been beaten and strangled to death. The man had escaped, possibly through a back door.
In fact, as investigators later found, she had been dead for between 12 and 24 hours.
Dale Kerstetter

At 11:00 PM on September 12, 1987, 50-year old Dale Kerstetter showed up to work the overnight shift as security guard at the Corning Glassworks plant in Bradford, Pennsylvania. Dale was a divorced father of six who worked at the plant for 29 years, but had recently been transferred from his position as a trades worker to a security guard, which involved him taking a pay cut of between $5,000-7,000 per year. At 7:00 AM the following morning, Dale’s relief arrived and discovered he was missing. Dale’s truck was still in the parking lot with the keys in the ignition. His daypack and a full carton of cigarettes were inside the truck, along with the holster for a .22 caliber gun he carried which was never found. Dale’s keys to the plant and a newspaper were found on a table in the cafeteria, along with his lunch pail, which still had all his food inside. A police dog was brought in and tracked Dale’s scent from the cafeteria to the second floor, but it came to an end at the plant’s glass furnace.
The security tape from that night was later checked. The plant had three security cameras and the feed would alternate between each camera at random intervals. The footage revealed an unidentified masked intruder walking through the plant at various points between midnight and 1:00 AM. In one of the shots, the intruder was seen meeting up with Dale in the back of the plant. They both walked past the security camera together, where Dale appeared to look up and stare directly at the camera before they disappeared out of frame. Dale did not show up in the security footage again, but one shot showed the intruder heading towards the glass furnace, the same area where the police dog tracked Dale’s scent. There was also a shot of the intruder wheeling a large bag through the plant on a manual forklift. It was soon discovered that $250,000 worth of platinum lining had been stolen from the furnace.
On the surface, it appeared the intruder had forced Dale to escort him to the area containing the platinum before he subsequently murdered him and disposed of his body. However, Corning’s management believed that Dale was actually involved in the theft.
When Dale walked through the plant and stared directly into the security camera, some people interpreted this as a signal for help, but Corning thought Dale might have been taunting them about his crime. At the time, Dale was in debt and unhappy that his employer had cut his pay and given him a security position, so Corning believed Dale willingly escorted the intruder to the furnace, helped him steal the platinum, and then skipped town with his share of the profits. Of course, Dale’s family did not believe he would get involved in anything illegal and abandon his children, so they feared he was an innocent victim of foul play. Whatever the truth, there has been no trace of Dale Kerstetter in nearly 30 years.
The Circleville Letters
A woman and her husband in Circleville, Ohio started getting creepy letters. One day, the husband received a letter and got riled up enough that he got his gun and left the house. He was letter found dead in a car crash, his gun had been fired. The husband’s brother was eventually charged with the crime, but began receiving the same letters once he was in prison.
Here’s a nice write-up on the whole store from The Line-up.
The Sodder Children

On Christmas Eve, December 24, 1945, a fire destroyed the Sodder home in Fayetteville, West Virginia, United States. At the time, it was occupied by George Sodder, his wife Jennie, and nine of their ten children. During the fire, George, Jennie, and four of the nine children escaped. The bodies of the other five children were never found. The Sodders believed for the rest of their lives that the five missing children survived.
Dave Bocks
A factory worker at a nuclear power plant went missing during his shift. Many people suspect foul play as he may have been a whistle blower for illegal activities taking place at the plant.
Blind River Killer
I remember this as the scariest episode of in which an elderly couple on a cross country road trip stopped at a rest area to sleep for the night. In the middle of the night attacked the couple and shot and killed a bystander to came to their aid. He drove off in a blue van and was never caught.
East Area Rapist / The Original Nightstalker

A serial rapist and killer who raped at least 50 women in northern California in the 70’s. He has never been identified.
A few things that make this killer a bit creepier than the rest:
1. The East Area Rapist sent letters and drawings to newspapers in the area taunting citizens. Here’s a map he drew of what is believed to be his “ideal” suburban neighborhood stalking grounds:

2. He would call and taunt his victims or intended victims. He called one woman he raped to wish her a merry Christmas, saying:
Merry Christmas, it’s me again! (hangs up)
You can listen to some of the phone calls here, but please be warned, these are very disturbing!!
3. There was a town meeting to discuss the rapist/killer at large. During the meeting one man stood up to say that the East Area Rapist could never harm his family because he wouldn’t “let” something like that happen to his wife. His wife was latter attacked leading people to believe the actual East Area Rapist attended the town meeting. A photo from that meeting exists.
Keddie Cabin Murders

From Wikipedia:
Glenna “Sue” Sharp, 36, and her five children had been renting the cabin since November 1980. At approximately 7:45 AM on the morning of April 12, Sheila Sharp, upon returning from the sleepover next door, discovered the tied-up bodies of Sue, John and Dana in the home’s living room. Plumas County Sheriff’s deputies later determined Tina Sharp was missing from the location. The murders have been commented upon for their particular viciousness.
After approximately 4,000 man-hours spent on the case, it grew cold but, in 1984, the cranium portion of a skull was recovered near Feather Falls in neighboring Butte County, a distance of roughly 63 miles (2 hours 12 minutes) from Keddie. Butte County Sheriff’s Office released both the original and back-up copy of the audio recording of the ‘anonymous call’ to an undisclosed member of law enforcement.
As of May 2017, no arrests have been made in connection with the Keddie murders, although two suspects who had criminal records, now deceased, have been proposed. In 2004, Cabin 28 was demolished.
There’s been a recent break in the case that, for many, may explain what happened:
On March 24, 2016, a hammer matching the description of a hammer suspect Martin Smartt said he lost shortly before the murders was taken into evidence by Plumas County Special Investigator Mike Gamberg. Sheriff Hagwood stated, “the location it was found… It would have been intentionally put there. It would not have been accidentally misplaced.
The Mothman
The Mothman sightings of 1966 was always a favorite story of mine and still is this day. If you go down the rabbit hole there are soooo many weird pieces including MIB showing up to this tiny town. Some of it might have been mass hysteria but damn if it isn’t a wild ride until the very end.
Morgan Nick

On June 9, 1995, Morgan Nick and her mother, Colleen Nick, went to a Little League baseball game in their town of Alma, Arkansas. At around 10:30 p.m., Morgan asked her mother if she could catch lightning bugs with her friends. At first, her mother was uncertain, but eventually let her go. She was last seen at 10:45 p.m. by her friends, emptying sand out of her shoes alone near her mother’s car while her group of friends emptied their shoes a few dozen feet away. Morgan’s friends reported seeing a “creepy” man talking to Morgan as she was putting her shoes back on.
When the game ended shortly thereafter, Morgan’s friends returned without her. They told Colleen that Morgan was at her car, but when Colleen returned to the car, Morgan was not there. She has not been seen or heard from since.
Pedro Lopez
A Columbian criminal known as the “Monster of the Andes” is out of prison after serving 13 years of a 16 year sentence for murdering as many as 300 little girls. No one knows where he is now.
Brian Shaffer
The medical student who went to a local bar for a drink and was never seen again. Security footage showed him entering the bar, but not leaving. He was by all accounts happy and had plans to propose to his girlfriend the following week. He hasn’t been seen since that night.
Hinterkaifeck murders

A few days prior to the crime, farmer Andreas Gruber told neighbors about discovering footprints in the snow leading from the edge of the forest to the farm, but none leading back. He also spoke about hearing footsteps in the attic and finding an unfamiliar newspaper on the farm. Furthermore, the house keys went missing several days before the murders. None of this was reported to the police prior to the attack.
Six months earlier, the previous maid had left the farm, claiming that it was haunted; the new maid, Maria Baumgartner, arrived on the farm on the day of the attack and was killed hours later.
Exactly what happened on that Friday evening cannot be said for certain. It is believed that the older couple, as well as their daughter Viktoria, and her daughter, Cäzilia, were all lured into the barn one by one, where they were killed. The perpetrator(s) then went into the house where they killed two‑year‑old Josef, who was sleeping in his cot in his mother’s bedroom, as well as the maid, Maria Baumgartner, in her bedchamber.
On the following Tuesday, April 4, neighbors came to the farmstead because none of its inhabitants had been seen for a few days.
Dorothy Jane Scott
Dorothy Jane Scott disappeared on May 28, 1980, in Anaheim, California. She had driven two co-workers to the hospital after one had been bitten by a spider. While they were waiting for a prescription to be filled, Scott went to get her car and bring it around to meet them. Her car approached them, but it sped away; neither could see who was driving as its headlights had blinded them. They reported her missing a couple of hours later, after not hearing from her. In the preceding months, Scott had been receiving anonymous phone calls from a man who had reportedly been stalking her. He had threatened to get her alone and “cut [her] up into bits so no one will ever find [her]”.
Dyatlov Pass Incident

The Dyatlov Pass Incident is the unsolved disappearance of nine hikers in the Ural mountains in Russia in 1959, and subsequent discovery. There’s a whole lot of details to this case which are mentioned in the link, but for a brief summary:
Ten experienced ski hikers embark upon a trek through a mountain pass that locals describe as “Devil’s Pass.”
One of the hikers returns on his own due to illness. The others continue ahead. After the party don’t return when expected, a search party is sent out into the mountains to look for them. Their campsite was eventually found, abandoned and slashed open from the inside, and the bodies were eventually all found at various points nearby in various unusual states, including some naked or undressed, some with their heads basically smashed in (which later investigations showed were impossible to have been done by humans).
This is a conspiracy theorist’s wet dream, with details that don’t add up, Cold War/KGB cover-ups, UFO sightings, cryptozoology (yeti theories), weapons testing, nuclear radiation emanating from the bodies, stories of local savage tribes etc. But even without all that, it’s still a pretty eerie story on its own.
Dyatlov Pass is a total rabbit hole and it’s one of my personal favorite mysteries.
Laureen Rahn
14-year-old Laureen Rahn was last seen in her apartment in Manchester, New Hampshire on April 26th, 1980. She spent the evening drinking beer with a male and female friend while her mother Judith was away at a tennis tournament. At some point, the boy heard voices in the hallway and left through the back door, thinking Judith was coming home. He stated he heard Laureen lock the door behind him.
When Judith finally returned at midnight, she found the building completely dark because the light bulbs on all three floors had been unscrewed. She checked Laureen’s room and thought she saw Laureen asleep on the bed. In the morning, however, this turned out to be Laureen’s friend, who said that she had last seen Laureen going to sleep on the couch. Laureen’s clothes and new sneakers were in the living room, and the back door was open.
The police investigation went nowhere until Judith looked at her phone bill and discovered she had been charged for three phone calls made from Santa Monica, California on October 1st, 1980, three months after Lauren went missing. Two of these calls were placed from a Santa Monica motel to another motel in Santa Ana. The third call was to a teen sexual assistance hotline run by a plastic surgeon. Authorities in Santa Monica questioned this surgeon, and he denied knowing anything about Laureen.
Judith hired her own investigator in 1985, who questioned the doctor again. This time he altered his story and said that his wife was sometimes visited by runaway girls (!?) and that one of these girls may have been from New Hampshire. He also believed that a colleague of his wife’s named Annie Sprinkle knew more about these runaways. Authorities looked into this and found that Sprinkle was involved in the pornography industry, but nothing was found linking her to Laureen.
Another investigator traveled to Santa Monica in 1986 and learned that the two hotels may have been used by a child pornographer named “Dr. Z.”, but authorities couldn’t find a connection between “Dr. Z” and the doctor who ran the hotline.
For a year after the disappearance, Judith reported getting regular phone calls at around 3:45 a.m., but there would be nothing but silence on the line when she answered. She received similar calls around the Christmas holidays for several years until she finally changed her number. According to Charley Project, a childhood friend of Laureen’s received a call from someone claiming to be her in 1986. His mother answered the phone, but unfortunately the article doesn’t elaborate on what the caller said.
In the previous thread about this, the OP quoted someone from a forum post who claims that her mother was the friend who was with Laureen when she vanished. Her mother said that they were hanging out with two guys that day (not one as stated in Charley Project) and that Laureen may have left with one of them. The guy who left through the back door committed suicide in 1985 and is not considered a suspect.
It is also worth nothing that other women, Denise Denault and Rachael Garden, of similar physical appearance to Laureen, disappeared from the same area within a six-week time period. Their cases are also unsolved and have never been linked.
The “30 Minutes or Less” murder
Brian Douglas Wells was an American pizza delivery man who was killed by a remotely controlled bomb fastened to his neck, under coercion from the maker of the bomb. After he was apprehended by the police for robbing a bank, the bomb was detonated.
“Down the hill”
On February 14, 2017, the bodies of Abigail “Abby” Williams and Liberty “Libby” German were discovered on an American hiking trail in Delphi, Indiana, after the young girls had disappeared from the same trail the previous day. The murders have received significant media coverage due to the fact that a photo and audio recording of a man believed to be girls’ murderer was found on the cell phone of German. Despite the photo and audio recording of the suspect being released to the public by police, and an estimated 18,000 tips being sent to police, no arrests have been made in the case.
