The Tapalpa raid that killed El Mencho triggers nationwide CJNG retaliation
Army kills the CJNG founder in a US-assisted operation; narco-blockades and shootouts ripple across multiple states, and a succession war opens
Summary
On 22 February 2026 the Mexican Army killed Nemesio Oseguera "El Mencho," founder of the Jalisco New Generation Cartel, and six others in a foot raid on a gated community in Tapalpa, Jalisco — an operation backed by US Joint Interagency Task Force-Counter Cartel intelligence after Washington's February 2025 FTO designations. CJNG gunmen fought back, and the kill set off blockades, vehicle burnings and shootouts across multiple states. With son "El Menchito" jailed in the US, no clear successor exists; by spring stepson Juan Carlos Valencia "El 03" emerged as a contested leader, and the April capture of Audias Flores Silva — alleged to be mobilising to seize control — confirmed an open succession war. Cartel attacks rose monthly: 324 in June. President Claudia Sheinbaum governs the fallout.
By the numbers
- 22 Feb 2026 — Tapalpa raid; El Mencho and six others killed.
- 756 — CJNG attacks recorded over the surveyed period (most of any group).
- 324 — total cartel attacks logged in June 2026, up from 271 in May.
- Feb 2025 — US designation of major cartels as Foreign Terrorist Organisations.
Why it matters
Decapitating Mexico's most aggressive cartel with US intelligence support is a test of the FTO-era playbook: whether a kill fragments the CJNG (as Sinaloa fractured) or just multiplies violence. Rising monthly attack tallies suggest the latter so far, raising the spectre of US strikes on Mexican soil.
What to watch
- Whether "El 03" consolidates or the CJNG splits into warring regional factions.
- Spillover with the Sinaloa Cartel's Chapitos-Mayos war into contested states.
- US pressure for direct strikes on Mexican cartels after the Venezuela precedent.
