Heraclio Guerrero Martínez, also known as "Tío Lako," is a significant figure in the Jalisco New Generation Cartel (CJNG) and recently experienced a personal tragedy when his son, Rubén Guerrero Valadez, aka 'El Láminas' or 'El R1', was killed during a military operation in Tapalpa, Jalisco. This operation aimed to detain Nemesio Oseguera Cervantes, infamously known as 'El Mencho', the cartel's leader. Reports indicate that Rubén was part of a close circle surrounding the former drug lord and was present at the Tapalpa Country Club at the time of the incident on February 22.
