Crimes

Motivated by delirious ideas, she orchestrated the murder with the complicity of her family to buy Santa Muerte's favor.
The first victim was Silvia Meraz's friend, Cleotilde Romero Pacheco, a 55-year-old-woman who was found dead in December 2009. Silvia Meraz attacked her with an ax. In June 2010, the cult murdered 10-year-old Martín Ríos Chaparro, the son in law of a sect member. The last murder was the sacrifice of Meraz's grandson, 10-year-old Jesús Octavio Martínez Yánez. The children were beheaded in rituals.
Detention
The cult buried the bodies in the city periphery. The state police discovered the bodies during an unrelated investigation. Later investigations led to the detention of Silvia Meraz Moreno and seven other people, all Meraz relatives, including the husband of Silvia Meraz, her son, father of the last victim and a minor.
