It wasn’t just another sweep. On October 18th, state and federal forces moved into Aguaruto Penitentiary—the most watched and whispered-about prison in Sinaloa. The operation, led by the Secretariat of Public Security (SSP), was officially described as a “search for prohibited items.” Inside, it looked more like a coordinated flex of power.
According to the SSP, units from the State Preventive Police (PEP) entered the facility’s modules while the Mexican Army and National Guard sealed the perimeter. The stated reason: a precautionary inspection following recent fights that left one inmate dead and three wounded.
The multi-agency deployment included the SSP, PEP, the Army, the National Guard, the Secretariat of the Navy (SEMAR), the Secretariat of Security and Citizen Protection (SSPC), the Attorney General’s Office (FGR), and the State Attorney General’s Office (FGE). They later claimed all seized items were turned over to ministerial authorities and that the inspection was carried out “without incident and in respect of human rights.”

Just one day earlier, on October 17th, Aguaruto had already gone hot. Around 1:40 p.m., a brawl erupted among inmates inside the facility—one man was killed, three others injured. Security personnel responded and reported seizing three long rifles, two handguns, and an improvised explosive device set to be destroyed on-site because of transport risk.
In the government’s words, order has been restored. But inside Aguaruto, “order” depends on who you ask.

Beneath the Surface
Messages shared among inmates tell a different version.
Sources from inside tell me two of the injured prisoners, were lavanderos—men assigned to wash clothes—caught in the middle when state forces burst into the prison’s patio areas. According to these same accounts, officers went module to module, searching inmates’ phones for photos and signs of contact with rival factions.
It’s a pattern familiar to those who follow Aguaruto’s politics: every “inspection” coincides with the prison’s internal power shifts. The official statement says nothing about rivalries, but among the inmates, the question isn’t whether the state is in control—it’s which faction the state is protecting.
For now, officials insist the situation is calm. Inside, it’s just another pause before the next reshuffle.
