8. Ed Gein
Ed Gein, also known as the Butcher of Plainfield, was an American serial killer who would make furniture and other items out of his victims' bodies. When he was finally apprehended and the police searched his home, they found a corset made from a female torso, a belt made from nipples, and a lampshade made of human skin, amongst many other things. The one above is a replica item you can buy on Etsy. Why.
Kris Kremers and Lisanne Froon were two Dutch women who went missing on a hike in Panama. A backpack containing their phones and a camera was found 10 weeks later. The first few photos are ordinary holiday shots taken at the beginning of their hike. The final 90 were taken a week later in a pitch-dark forest, and show strange items. Their remains (including bleached bones) were finally found almost a year after they first went missing.
