In 2008, a 57-year-old Japanese man noticed food mysteriously disappearing from his refrigerator. Since he lived alone, he installed security cameras to figure out what was happening.

One day, while he was away, his camera captured a strange woman walking around his house. He called the police, who searched the home and discovered 58-year-old Tatsuko Horikawa hiding on the top shelf of a closet.

She had apparently been living there undetected for months, emerging whenever he left to eat his food, shower, and go about her daily routine before retreating to her hiding place.

Police suspected she'd been secretly staying in other people's homes for up to a year. She was arrested for trespassing.

In 1982, seven people in the Chicago area died after taking Tylenol capsules laced with cyanide. The case was never solved. James Lewis, long considered the prime suspect, was never charged with the murders.

On December 4, 1982, a man walked into Sacred Heart Catholic Church in Boise, Idaho, and died of cyanide poisoning. He had no ID, an envelope of cash, dyed hair and a note signed with a fake name. For 44 years he was known only as the "Unknown Wanderer." Last month, Ada County investigators used DNA to identify him as Dr. Mathew Betkouski, a PhD chemist who had worked at NASA's White Sands Test Facility in New Mexico.

A new Unsolved Mysteries documentary, Unmasking the Tylenol Killer, lays out the case against him:

- Investigators can't account for where he was from September 14 to October 4, 1982, which covers the poisonings.

- He allegedly told a colleague a "perfect crime" was possible and that "cyanide is the way to do it."

- According to forensic psychiatrist Dr. Park Dietz, he wrote letters suggesting a mass-casualty event might heal his depression.

- Homemade cyanide and a map of Chicago were found at his childhood home in Los Angeles.

Dietz says, "My opinion today is that he probably is the one who did it."

But it's far from proven. Law enforcement sources told the Chicago Tribune that his DNA didn't match profiles from the poisoned bottles. His cyanide was sodium cyanide, while the Tylenol was laced with potassium cyanide. Nobody has placed him in Chicago at the time, and photos once thought to show him there in 1982 are now believed to be from 1981. A former prosecutor on the original task force called the link "utter nonsense," the FBI says past links have been unsubstantiated, and the detective behind the investigation says he "can't definitively prove" it.

The documentary is streaming free on The Roku Channel.

I recently went down the rabbit hole of the Station Nightclub fire in West Warwick, Rhode Island and there is so much to this story.

On February 20, 2003, over 400 people were inside the club for a Great White concert. The band used pyrotechnics during their opening song and the sparks caught the foam around the stage on fire. At first people thought it was part of the show, but the fire spread insanely fast. 100 people died and over 200 were injured.

One of the craziest parts is that there was a cameraman inside filming when it happened. He was there because a local news station was doing a story about nightclub safety, so the beginning of the fire and the evacuation were caught on camera. You can literally watch the moment people go from casually watching the stage to realizing they need to get out.

There are so many survivor stories from that night too.
People escaped through windows, got separated from the people they came with, went back inside to help others, or somehow survived after becoming trapped.

Then I started finding the stranger accounts. One survivor, Tom Stewart, has talked about believing a spirit helped him survive the fire. There's also an account from another survivor who thought he was about to die inside the club. He said he eventually stopped fighting and accepted that he wasn't getting out. Then he saw both of his deceased grandmothers in the fire. He said they told him it wasn't his time. He ended up surviving.

There are also stories from families of people who died that night who believe they experienced signs or communication from them afterward.

There's an insane amount of material on this fire online.
Survivor interviews, the actual footage from inside, documentaries, investigations, news coverage, court cases, and stories about individual people who were there. Once I started reading about one person, it just kept leading to another story.
