Mexican authorities have delivered a massive blow to the Sinaloa Cartel faction known as "La Mayiza" after arresting a man that served as the clique's top fentanyl producer and had deep family ties with Joaquín "El Chapo" Guzmán and his sons.
Following a series of intelligence and surveillance reports, federal law enforcement in Sinaloa secured the arrest of Hernán Domingo Ojeda López, commonly known as "El Mero Mero," who was not only described as a generator of violence and a member of the Sinaloa Cartel but also the uncle of Ovidio Guzmán López, one of El Chapo's sons who is currently behind bars in the U.S.
