Overview
- The riot began around midday on Friday, May 22, in pavilion 3 of the Centro de Reinserción Social in Ciudad Obregón and included reports of gunshots, leaving two inmates dead and seven people injured.
- Security protocols were activated and municipal, state and federal forces, along with ambulances and Cruz Roja paramedics, regained control of the prison and moved the wounded to hospitals for evaluation.
- The Fiscalía General de Justicia de Sonora has identified four inmates as presumed initiators and said it will file criminal imputations for homicide and aggravated injuries against them as investigations continue.
- Relatives of inmates blocked Federal Highway Mexico 15 for more than 12 hours to demand information and access and reopened the road after authorities permitted visits to detainees.
- Officials said recent searches inside the Cereso seized prohibited items and investigators are probing weapon use and each person’s role, a process that could lead to more charges and a sustained security presence around the prison.
