A fire and explosion at a Waldo’s discount store in downtown Hermosillo, Mexico, resulted in 24 people being killed, including several children, on Saturday, November 1, 2025, during Day of the Dead festivities. Additionally, several people sustained injuries, with four remaining hospitalized as of Wednesday, November 5.
The fire ignited at the convenience store in the capital of Sonora state, with large flames consuming the building. Sonora Governor Alfonso Durazo confirmed the event via a video on social media, while Attorney General Gustavo Salas Chávez shared details regarding the casualties and injuries.
Initial investigations indicated that the victims succumbed to toxic gas inhalation rather than burns. Salas Chávez mentioned that there is no current evidence suggesting intentionality, but all possibilities remain open. Early reports from the prosecutor suggest that the fire may have originated in a transformer; however, the exact cause is still under investigation.
Social media videos captured the scene, showing the store engulfed in flames, with dense black smoke emanating from the building. One video showed a burned individual collapsing near the store entrance amidst the ongoing fire.
Those injured were sent to six different hospitals in Hermosillo, where medical staff worked to stabilize patients, many of whom suffered from severe smoke inhalation and burns. The incident coincided with one of Mexico’s major cultural events, where families traditionally gather to remember deceased loved ones.
Mexican President Claudia Sheinbaum extended her condolences to the affected families in a public statement. She confirmed discussions with Governor Durazo to organize support efforts and directed Interior Secretary Rosa Icela Rodríguez to send a team to assist the victims’ families and the injured.
Waldo’s, the discount chain, issued a statement expressing sorrow over the deaths and committed to fully cooperating with the investigation. The company conveyed condolences to the victims and their families as authorities work to determine the cause of the fire.
The disaster’s timing added to the tragedy, as the Day of the Dead holiday typically increases store foot traffic, with families purchasing supplies for traditional observances. The celebration, from October 31 to November 2, involved cemetery visits, home altars adorned with photos and offerings, and festive meals in honor of departed family members.
In downtown Hermosillo, a city with approximately 900,000 residents, located roughly 170 miles south of the Arizona border, emergency response operations were initiated as firefighters battled the flames. Local authorities collaborated with state and federal officials to manage the situation and provide support to survivors.
The presence of children among the fatalities has heightened the community’s emotional response. Families who lost members face the dual challenge of grieving during a holiday dedicated to remembering the dead, creating a difficult period of mourning.
Emergency personnel continued to monitor the four remaining hospitalized individuals. The finding of toxic gas inhalation suggests that victims may have been quickly incapacitated, possibly explaining the high number of casualties.
State authorities have initiated a thorough investigation into the store’s safety measures, including fire suppression systems, emergency exits, and electrical infrastructure. The potential transformer issue has led to an examination of maintenance records and building code compliance.
As of Wednesday, November 5, 23 victims had been identified, authorities confirmed. Six children aged 10 and under are among the dead, including a 10-month-old baby boy. Four people remained hospitalized, down from the initial six reported Sunday. An 81-year-old man remained in critical condition, while a 20-year-old woman was transferred to Valleywise Health Medical Center in Phoenix for specialized treatment.
In response to mounting calls for justice and transparency, Governor Durazo announced that the head of the state’s civil protection service would be removed for the duration of the investigation. Hermosillo Mayor Antonio Astiazarán similarly removed the head of the city’s civil protection service to ensure the investigation proceeds from “a place of neutrality.”
The death toll rose to 24 after 81-year-old Marco Segundo Reyes died on November 6 from complications related to burns covering much of his body.
The incident sparked widespread protests and calls for justice, with demonstrators drawing painful parallels to a 2009 daycare fire in Hermosillo that killed 49 children. On November 5, hundreds marched to the Government Palace, chanting “49+23, how many more?” and “Never again,” led by activists from the June 5 Movement—an association of survivors and parents from the 2009 disaster. State authorities revealed that Waldo’s was operating without proper safety certifications, and investigators uncovered serious irregularities, including the improper installation of a transformer indoors and the lack of emergency exits.
Sonora Governor Alfonso Durazo removed the head of the state civil protection service for the duration of the investigation, and Hermosillo’s civil protection leader was also dismissed to ensure impartiality. Waldo’s closed all 68 of its stores in Sonora following the fire and pledged to continue providing financial support to victims’ families for medical costs and funeral expenses.
As of early December, the investigation remained ongoing more than a month after the disaster, with a makeshift memorial outside the burned store growing to include protest signs demanding accountability and “no more victims.”
As of January 15, 2026, the Waldo’s fire remains one of the deadliest single-incident retail disasters in recent Mexican history. Authorities in Sonora have not announced arrests or a definitive cause, maintaining that the investigation is still ongoing and that no evidence of deliberate action has been confirmed. While all injured survivors have since been discharged and the victims formally identified, questions persist about building safety, emergency response, and whether the tragedy could have been prevented. For families still grieving, the disaster stands as a devastating reminder of how quickly ordinary moments can turn catastrophic—and of the urgent need for accountability to ensure that such a loss of life is never repeated.
