In late July 2026, a violent altercation occurred at the Aguaruto Penitentiary in Culiacán, Sinaloa. During the disturbance, an inmate sustained injuries from a bladed weapon and died while being transported for emergency medical care. Security forces, including the National Guard and the Mexican Army, established a perimeter around the facility as authorities launched a forensic investigation.

By mid-August 2026, further inmate deaths were reported in separate facilities. In Morelos, Mexico, an inmate died following a dormitory fight involving sharp objects at the Atlacholoaya Social Reinsertion Center. Additionally, a separate incident was reported in Mendoza, Argentina, where an inmate was found dead in her cell at the Almafuerte II penitentiary complex; while investigations are ongoing, officials indicated the death appeared to be a suicide.
