A shooting inside a prison in the Mexican state of Sinaloa killed 10 people on Thursday afternoon, including a minor who was visiting a relative, local officials said. At least 17 inmates were wounded in the attack at El Castillo prison in the Pacific coast city of Mazatlan.

The violence began in cellblock 4 after gunshots were heard and then spread to cellblock 5, according to the prison director. Nine inmates and the minor were killed, and the 17 injured inmates were taken for medical treatment. Details about their conditions were not immediately available.

Military personnel, National Guard members, and state and municipal police responded to the prison. "The prison is currently under control," Sinaloa's public security department said in a statement, adding that authorities remain at the facility to maintain security.

Preliminary information indicated that at least two 9-millimeter handguns were used. State prosecutors will determine how many weapons were involved and how many people took part in the attack. Authorities will also investigate how the guns entered the prison and whether anyone helped bring them through security controls.

Sinaloa has been the scene of an internal conflict within the Sinaloa cartel between allies of co-founder Ismael "El Mayo" Zambada and Los Chapitos, a faction associated with the sons of Joaquin "El Chapo" Guzman. The fighting erupted in September 2024, following Zambada's capture and transfer to US custody in July of that year. Guzman is serving a life sentence in the United States.

Analysis

Why This Matters

  • The attack shows cartel violence reaching inside a state prison, where authorities are expected to guarantee safety.
  • The death of a visiting minor highlights the risks faced by family members of inmates in regions affected by cartel conflict.
  • The investigation into how weapons entered the facility will test whether prison security failures enabled the attack.

Background

Sinaloa state has experienced an internal war within the Sinaloa cartel since September 2024. That conflict followed the capture and transfer of co-founder Ismael "El Mayo" Zambada to US custody in July 2024. The fighting pitted allies of Zambada against Los Chapitos, a faction led by sons of Joaquin "El Chapo" Guzman, who is serving a life sentence in the United States. Prisons in the region have been affected by the broader security deterioration associated with that rivalry.

Key Perspectives

Sinaloa public security department: Officials say the prison is under control and that authorities remain on site to maintain order. State prosecutors: They are responsible for determining how many weapons were used, how many people participated, and how guns got past security checks. Local officials and witnesses: The prison director reported an attack involving inmates, and local news coverage described the violence spreading between cellblocks.

What to Watch

  • The official count of weapons and participants once the state prosecutor's investigation is completed.
  • Whether the inquiry identifies staff who may have helped smuggle the handguns into the prison.
  • Any further escalation in cartel-related violence in the Mazatlan area following the attack.
