What are some of the most disturbing 'true crime stalker stories' you've heard?

The most disturbing one I heard was when a family thought they were renting a house. They paid the deposit and first month's rent. But when they showed up on moving day, the 'owner' had already rented it to someone else and refused to return their money. They were left homeless and out of a large sum of money.

One story I heard was about a girl who noticed the same man everywhere she went - at the grocery store, near her work, and even outside her apartment. He would always stare at her intently. One day, she found a strange note in her mailbox with details about her daily routine. It was so creepy.

In a summer camp deep in the mountains, there was a story of a group of campers who found a dead body in the woods. They were out on a nature walk when they stumbled upon it. It was an old hiker who had probably passed away from natural causes, but for the young campers, it was a horrifying discovery. They had to wait for the authorities to come, and the whole experience haunted them for a long time. It was a really disturbing encounter that no one expected at a summer camp.

A colleague of mine had a really bad experience. An internet stalker created a fake profile using her pictures and started interacting with people she knew, spreading false rumors about her. It was so horrible as she had to deal with the aftermath of people believing those lies. She had to go through a lot of trouble to prove it wasn't her and get the fake profile taken down.

A prison had a rule where inmates were not allowed to speak during meal times. If they did, they would be put in solitary confinement. One inmate accidentally made a noise while eating and was sent to that dark, lonely cell for days. It was a really disturbing situation.

There's a story about a sociopath in a high school. He targeted the loneliest students. He would befriend them, gain their trust, and then start spreading their darkest secrets around the school. He made some students so depressed that they considered suicide. It's really a horror story as it shows how cruel a sociopath can be to the vulnerable.

I heard of a story where a patient got an infection from a dirty surgical instrument. The infection spread rapidly and caused the patient to be in constant agony. It took a long time and a lot of strong antibiotics to finally get the infection under control. This shows how crucial strict hygiene is in medical settings.

A friend told me about a person she thought was her friend. This 'friend' would steal small things from her like hairbands or earrings and then deny it. But she would later find those items in the 'friend's' bag. It was really disturbing.

A disturbing one is the story of a large oil spill. The oil spread across the ocean, coating birds and marine animals. The birds couldn't fly as their feathers were stuck together by the thick oil. They just sat there helplessly, waiting to die. It was heart - breaking to see such beautiful creatures in that state because of human carelessness.

There's the story of a girl who believed that she was shrinking. She became so obsessed with it that she stopped eating, thinking that if she ate, she would grow too big too fast. As a result, she became severely malnourished. It's a disturbing tale of how a false belief can be so harmful to one's physical and mental health. The doctors tried hard to make her understand that she wasn't actually shrinking, but it was a long and difficult process.
