1. Magdalena Solis
Magdalena Solis (also known as the High Priestess of Blood) was a Mexican serial killer and cult member.
She became a prostitute at a young age and is one of the few documented cases of female serial killers who had clear sexual motivations.
In 1963, Solis and her brother were contacted by a pair of criminals, the Hernandez brothers. They tricked the poor and illiterate people of a small town into believing they were prophets of the Inca gods.
After a few months, the villagers realized they weren’t getting any richer, despite doing everything the “prophets” said. That’s when the brothers claimed Magdalena was the reincarnation of a goddess—to restore faith.
Magdalena demanded human sacrifice and devised a ritual that consisted of the brutal beating, burning, cutting, and maiming of the victim.
In May 1963, a 14-year-old local accidentally witnessed one of those rituals. He immediately reported it to the police, and a detective escorted him back to the village.
The Solis siblings were arrested and the Hernandez brothers killed. Magdalena and Eleazar were sentenced to 50 years in prison for only two homicides because the police were unable to confirm their participation in the other murders.
