Today, Watu Simba (were-lion) stories are used to scare misbehaving children. But in the ’40s, the Watu Simba were young women who had been enslaved by East African witch doctors. They were forcefully addicted to drugs to make them compliant, forced to live in tight cages, and had their foot tendons reshaped to give them the gait of a stalking lion. The witch doctors would then send them out as assassins. The Watu Simba wore the skin of a lion and were outfitted with prosthetic claws while hunting. Most shockingly, they were primarily fed the meat of their victims. They killed approximately 300 people over the course of four years and continued to kill even after the witch doctors were captured and hanged.
