A fire followed by an explosion at a Waldo’s discount store in downtown Hermosillo, Mexico, resulted in the deaths of at least 23 individuals, including several children, on Saturday, November 1, 2025. The incident occurred during Day of the Dead festivities, with 12 others injured and six still hospitalized as of Sunday morning.
The fire started at the convenience store in the capital of Sonora state, causing large flames to engulf the building. Sonora Governor Alfonso Durazo confirmed the event through a video on social media, while Attorney General Gustavo Salas Chávez provided information on the fatalities and injuries.
Initial investigations indicated that victims succumbed to inhalation of toxic gases rather than burns. Salas Chávez mentioned that there is no current evidence suggesting the fire was deliberate, though all possibilities are being examined. Preliminary reports suggest the fire might have originated from a transformer, yet the exact cause is still under investigation.
Footage on social media showed the intense scene, with flames overtaking the Waldo’s store as black smoke emerged from the building. One video depicted a severely burned man collapsing near the store entrance while the fire blazed behind him.
The injured were taken to six different hospitals across Hermosillo for treatment. Medical personnel worked over the weekend to stabilize those affected, many suffering from serious smoke inhalation and burns. This incident coincided with one of Mexico’s major cultural events, where families traditionally gather to pay tribute to deceased relatives.
Mexican President Claudia Sheinbaum extended condolences to the families affected in a public statement. She confirmed ongoing communication with Governor Durazo to coordinate support efforts and directed Interior Secretary Rosa Icela RodrÃguez to send a team to aid families of the victims and the injured.
The discount chain Waldo’s released a statement expressing sorrow over the deaths and pledged full cooperation with authorities investigating the incident. The company extended sympathies to the victims and their families while efforts continue to determine the cause of the fire.
The timing of the incident added to the gravity, as the Day of the Dead holiday typically results in increased store traffic as families purchase items for traditional observances. The holiday, which runs from October 31 to November 2, involves gatherings at cemeteries, home altars with photos and offerings, and meals honoring departed loved ones.
Downtown Hermosillo, a city of approximately 900,000 residents located about 273 kilometers (170 miles) south of the Arizona border, became the center of emergency response efforts as firefighters worked to control the blaze. Local authorities coordinated with state and federal officials to manage the crisis and provide assistance to survivors.
The inclusion of children among the casualties has deepened the community’s emotional impact. Families mourning their loved ones face the dual challenge of grief during a holiday dedicated to remembering the dead.
Emergency responders continue to monitor the six individuals who remain hospitalized, while forensic teams work to identify all victims and determine the series of events leading to the disaster. The finding of toxic gas inhalation suggests victims may have been swiftly overwhelmed, potentially explaining the high number of casualties.
State authorities have initiated a thorough investigation into safety protocols at the store, including fire suppression systems, emergency exits, and electrical infrastructure. The potential transformer issue has prompted a review of maintenance records and building code compliance.
This disaster ranks among the deadliest single-incident fires in recent Mexican history. As the investigation unfolds, there are ongoing inquiries about whether preventable factors contributed to the high number of casualties and what measures might prevent similar incidents in commercial venues across the country.
