The Mayiza, also known as the Mayos, is a faction of the Sinaloa Cartel linked to longtime leader Ismael Zambada García, alias “El Mayo.” Following his controversial arrest in 2024, the cell is currently led by one of his sons, Ismael Zambada Sicairos, alias “Mayito Flaco.” This week, the group made headlines after US authorities offered $5 million for information leading to the arrest of Juan José Ponce Félix, alias “El Ruso,” the alleged leader of the faction’s armed wing.
