Two Years Into the Sinaloa Cartel Civil War: Guzmán Brothers and Mayito Flaco Still at Large as Toll Passes 3,700

On the two-year anniversary of the September 9, 2024 outbreak of open war between La Mayiza and Los Chapitos, Mexican outlets reported the state's three fugitive faction leaders — Iván Archivaldo and Jesús Alfredo Guzmán Salazar (Los Chapitos) and Ismael Zambada Sicairos 'Mayito Flaco' (La Mayiza) — remain at large. Iván reportedly escaped through a three-block tunnel in February 2025 and, along with Alfredo, is believed to have fled Sinaloa entirely for Sonora, Querétaro, or possibly Costa Rica, while continuing since roughly 2025 to explore a negotiated surrender with U.S. authorities without a confirmed deal; the U.S. offers a $10 million bounty for each brother. Mayito Flaco is reported hiding in Durango under the protection of the Cabrera Sarabia brothers. Local tallies put the cumulative toll since the war began at roughly 3,724 homicides, including a spike of 41 killed between August 31 and September 5 — one of the conflict's deadliest weeks — versus a lower federal count of 30 for the same period.
