00:00If the Zodiac is still alive, he's probably laughing because he's been watching other people be accused of his crimes for years.
00:07Welcome to WatchMojo, and today we're looking at some of the most unsettling unsolved crimes.
00:12The only name linked with the Whitechapel murders is strange character who prowls about after midnight.
00:19The Chicago Tylenol Murders
00:21In late 1982, there was a massive recall of Tylenol in the U.S.
00:25It is arguably the most recognizable over-the-counter medication, and millions reach for it daily.
00:31This recall wasn't due to a manufacturing snafu, however.
00:34It was due to potassium cyanide contamination.
00:37Poisoned Tylenol was found still on the shelf at Woodfield Mall.
00:41It is believed that numerous bottles had been tampered with in pharmacies,
00:45with mysterious offenders opening them and tainting the capsules before returning them to the shelves.
00:49The capsules came off the shelves. The testing began.
00:53Before this incident, which took the lives of at least seven individuals,
00:57medication bottles did not have secure seals.
00:59The Chicago Tylenol Murders inspired the implementation of strict laws involving tamper-resistant seals.
01:05The perpetrators were never caught, and the crime remains unsolved.
01:10No one has ever been charged with the murders.
01:12The Monster with 21 Faces
01:14In 1984, an anonymous source nicknamed The Monster with 21 Faces terrorized Japanese food processing companies.
01:21It began with the kidnapping of Katsuhisa Aizaki, CEO of Guriko.
01:26Aizaki managed to escape, but the perpetrator, believed to be male,
01:30retaliated by setting fire to several vehicles outside Guriko's headquarters.
01:35The enigmatic criminal sent letters to police,
01:37gloating about his actions and mocking the lawman's incompetence for failing to solve the crimes.
01:42He also claimed to have poisoned Guriko products with cyanide, forcing a recall worth $21 million.
01:48He eventually shifted his threats to other food processing companies, with some poisoned products actually found.
01:54The Monster ceased operations after the police superintendent took his own life,
01:58citing shame from not being able to solve the crimes.
02:02The Oslo Plaza Woman
02:03In May 1995, a woman checked into a high-end Norway hotel under the false name Jennifer Fairgate.
02:10She did not provide ID or a credit card, which wasn't common hotel practice.
02:15When sent to claim payment, a security guard heard a gunshot.
02:18And in a second later,
02:20that was a gunshot.
02:24When guards entered, the woman was found deceased, with a single bullet wound to the head.
02:29This seems like a case of taking one's own life.
02:32However, she was found holding the gun in an illogical position,
02:36and with no signs of gun residue or blood spatter on herself.
02:40Her clothing had all tags ripped out, and no ID in sight.
02:43There is no family to notify, because this person doesn't exist.
02:49She had checked in under a false name.
02:51She remains unclaimed, and her case was closed after one year, citing self-deletion.
02:56But many beg to differ to this day.
02:58If I could spread this story wide enough,
03:02that could give us valuable information about her life,
03:06and that could tell us what happened in room 2805.
03:10The Elisa Lam mystery
03:11In 2013, a young Canadian tourist, Elisa Lam,
03:16checked into the stay-on-main hotel,
03:18formerly the Cecil Hotel in Los Angeles.
03:20She was traveling alone, checking in with her parents daily.
03:24She had bipolar disorder and depression,
03:26for which she was medicated, but sometimes skipped her doses.
03:30After failing to check in for a week,
03:31her parents reported her missing.
03:3330 seconds later, the door closes, and she's never seen again.
03:37Around 10 days later, hotel tenants complained about water pressure and quality.
03:42Upon checking the rooftop water source,
03:44a maintenance worker found the body of Lam in one of the four tanks.
03:47This case gained attention when police released security footage of Lam behaving oddly in the hotel elevator.
03:53Do you believe she's interacting with another person?
03:56I don't know.
03:56The case was deemed an accidental drowning,
03:59but the video and circumstances raise many unresolved questions.
04:03It says, if guests stay, quote,
04:05you do so at your own risk and peril.
04:08The Highway of Tears
04:09A 719-kilometer stretch of Highway 16 in British Columbia, Canada,
04:14has been the site of an unthinkable amount of crimes.
04:16If you go by the RCMP numbers,
04:19nine women have gone missing or been murdered along that specific stretch of highway.
04:24The road's conditions are considered ideal for commitment of crimes.
04:27Isolated, remote, soft soils for burying evidence or victims,
04:31and the stretch shockingly did not have cellular service until late 2024.
04:36Since 1970, though the number is debated,
04:39upwards of 40 indigenous women have lost their lives or gone missing on Highway 16,
04:44nicknamed the Highway of Tears in 1996.
04:47Being murdered, most of the cases are unsolved,
04:50and once again, most of those women were indigenous.
04:54At least three serial killers have been linked to the area.
04:57Edward Dennis Isaac, Brian Peter Arp, and Cody Lejabakov.
05:00The last officially recorded homicide occurred in 2023.
05:04Many of the cases remain unsolved.
05:07The result, some say, of systemic racism in the Royal Canadian Mounted Police.
05:11If they're still alive, it's a matter of how do you find them,
05:15and when you find them, how do you get them to talk to you?
05:18The Ice Valley Mystery
05:19In 1970, the body of a woman was found in Isdalen, or Ice Valley, Bergen, Norway.
05:25Though it was initially concluded that she had taken her own life,
05:29circumstances render this debatable.
05:31She was found next to the remnants of a campfire,
05:33burned beyond facial recognition.
05:35There were multiple items around her, such as clothing and liquor bottles.
05:43All tags had been removed from clothing, similar to the Jennifer Fairgate case.
05:47Removing tags is a common practice for intelligence officers to avoid tracing.
05:51The autopsy cited the cause of death as incapacitation by sleeping pills,
05:5650 to 70 tablets ingested, and carbon monoxide poisoning.
05:59The woman's suitcases were located at the railway station,
06:02containing false passports and IDs.
06:05She has never been identified.
06:0746 years later, the Ice Valley is still a good one.
06:11The Zodiac Killer
06:13Between 1968 and 1969, the Zodiac, nicknamed by himself in his letters,
06:19terrorized the San Francisco Bay Area.
06:22The hooded figure demanded their car keys and their money.
06:24He had five official murder victims,
06:27and made his presence anonymously known by sending a series of letters to media outlets.
06:32In these poorly spelled letters, he boasted about his crimes,
06:35claimed he had taken lives to collect slaves for the afterlife,
06:38and included cryptograms,
06:40one of which was only deciphered in 2020,
06:4351 years after its conception.
06:45He claims to be collecting slaves for his afterlife.
06:50It suggests a dark insight into the killer's mind.
06:53He also claimed to have taken 37 lives in one of his messages,
06:58though this hasn't officially been substantiated.
07:00The Zodiac fell into obscurity after 1974.
07:04The SFPD has claimed that around 2,500 suspects have been investigated,
07:08but the case remains unsolved.
07:10The FBI released a statement saying,
07:13The Zodiac Killer case remains an ongoing investigation for the FBI San Francisco division.
07:19The Hinterkaifeck Murders
07:20In 1922, a family of five and their maid were murdered on a Bavarian farm in Germany.
07:26The circumstances surrounding the murders were odd,
07:28as the family had reported hearing footsteps in the attic and finding mysterious prints in the snow,
07:33among other things.
07:35Four family members were believed to have been lured to the barn one by one
07:38and murdered with a mattock, or pickaxe.
07:41The killer then entered the house and took the lives of the youngest child in his bassinet,
07:45followed by the maid who was on her second day of employment.
07:49The bodies were found days later.
07:51There was evidence that the perpetrator stayed in the home for a few days post-crime.
07:55There were many suspects, but the case remains cold.
07:59The Sauter family disappearance
08:00In West Virginia, a house fire devastated the Sauter family on Christmas Eve 1945.
08:06Family patriarch George Sauter was an Italian immigrant,
08:09having settled down with his wife and 10 children,
08:12nine of whom were at home on that fateful evening.
08:14Kids are celebrating Christmas Eve.
08:16They're allowed to stay up well past their bedtime.
08:19Unbeknownst to them, all of their lives are going to change within a matter of hours.
08:22Sauter was known to have openly criticized Benito Mussolini,
08:26drawing ire from acquaintances, a possible motive for arson.
08:29The couple and four of their children managed to escape the inferno.
08:32The others did not.
08:35Within minutes, George, Jenny, and four of their children run outside.
08:39When the ashes of the home were searched, no remains were found.
08:42It was believed by some, including the parents,
08:45that they had been removed from the home before the arson.
08:48George Sauter searched for his family until his death in 1969,
08:51and the case remains unsolved.
08:54They didn't find any traces of these bodies.
08:56No bones, not even a piece of a tooth.

09:14Jack the Ripper
09:15In London's Whitechapel district in 1888,
09:18a number of working girls were brutally murdered.
09:21There were five confirmed victims, and many more alleged.
09:25She had been disemboweled.
09:28Jack the Ripper's reign of terror had begun.
09:31Much like the Zodiac,
09:32Jack the Ripper letters were received by media and police,
09:35though their authenticity was and has been debated.
09:38There were many hoaxes about.
09:40It was deduced by authorities at the time
09:42that the perpetrator must have been a butcher or medical professional,
09:45given the wounds sustained by the victims,
09:47though this was debated as well.
09:49Still, even with a corpse,
09:51an approximate time of death and knowledge of the weapon,
09:54the police had little to work with.
09:56In early 2025,
09:58an author and self-proclaimed Ripperologist
10:00claimed to have found the identity of the Ripper,
10:03but his evidence hasn't been substantiated,
10:05DNA from a shawl,
10:06though some experts claim this is impossible.
10:09The case remains cold.
10:10It's not nearly enough information
10:13to say with any kind of certainty
10:15that this is the man that is Jack Ripper.
10:17What other unsolved mysteries should we have mentioned?
10:19Let us know in the comments.
10:21One year later,
10:22the Tylenol case remains unsolved.
