Transformer Suspected in Waldo’s Blast That Killed 23

An explosion and fire tore through a Waldo’s discount store in downtown Hermosillo, Sonora, on Saturday, killing at least 23 people, including children, and injuring about 12–15 others, with several hospitalized and some in critical condition. Witnesses reported a sequence of power outages and surges just before the blast, and prosecutors and forensic teams say most victims appear to have died from inhalation of toxic gases. Investigators are probing a transformer located inside the store as the likely accidental source and say there is no evidence so far of an intentional attack. Governor Alfonso Durazo ordered a thorough, transparent probe and pledged medical, psychological and social support, while President Claudia Sheinbaum sent federal teams to assist victims’ families and oversee the response. Waldo’s said it is cooperating with authorities and offering support to families; Hermosillo canceled official Día de Muertos festivities as officials continue identifying bodies, notifying relatives and obtaining documentation from the store’s owners.
