Magdalena Solís

Magdalena Solís (1947 – date of death unknown), known as The High Priestess of Blood (Spanish: la Gran Sacerdotisa de la Sangre), allegedly was a Mexican serial killer and cult leader responsible for orchestrating several murders which involved the drinking of the victims' blood. The murders were committed in Yerbabuena, Tamaulipas, during the early 1960s.

Solís was convicted of two of the murders and sentenced to 50 years in prison; authorities ascribed eight murders to Solís and suspected she was involved in as many as 15. She is regarded as one of the few documented instances of a sexually-motivated female serial killer, showing organized, visionary, and hedonistic characteristics.
