The fire broke out on Saturday afternoon, November 1, 2025, inside a discount store in Hermosillo’s downtown area. Witnesses described hearing a loud explosion before flames rapidly engulfed the building. Local reports indicate that the fire started in the store’s electrical transformer system, sparking an explosion that sent thick smoke throughout the premises.
