An agent of the Agencia Ministerial de Investigación Criminal (AMIC) was killed on the night of Wednesday, October 28, 2026, during a shooting attack on the agency's operational base in Magdalena de Kino, Sonora, according to the state Attorney General's Office, which opened a homicide investigation file.
AMIC is the criminal investigation arm of the state prosecutor's office: its operational bases carry out investigative steps, execute arrest warrants and sustain the inquiries that the public prosecutor brings before judges. The attack occurred at around 19:44 hours, when individuals fired from outside the building located in the Centro neighborhood, according to El Universal. La Jornada separately reported the death of a criminal investigation agent during the assault on the facilities. For Mexico, the episode turns attention to the day-to-day operation of state prosecutor's offices, the body that determines whether a case reaches a court or not.
The deceased agent was identified as Alberto Guzmán Aguiar, assigned to the AMIC Operational Base, who lost his life at the scene. Following the attack, an operation was deployed involving AMIC, the 45th Military Zone of the Secretariat of National Defense, the State Public Security Police, the Municipal Police and forensic services, which processed the scene. The prosecutor's office stated that it keeps the investigation open to identify those responsible and bring them to justice, and reported no arrests. A day earlier, on Tuesday, October 27, a man entered the Municipal Public Security Directorate of Sáric, a border municipality 90 kilometers from Magdalena de Kino, and allegedly started a fire that damaged the agency's two patrol vehicles. The municipality was temporarily left without official vehicles for surveillance work and no injuries were reported.
Both investigations remain ongoing and the prosecutor's office has not reported anyone detained for either incident. The progress of those case files and the identification of those responsible are the next verifiable point in tracking attacks on security agencies in northern Sonora.
