Overview
- State prosecutors say the leading hypothesis is an accidental electrical failure, with no evidence of intentionality, as experts examine a private in‑store transformer and rooftop solar converters not tied to CFE infrastructure.
 - Officials report the Hermosillo branch lacked an approved Civil Protection plan since 2021 and had only a single entrance with no emergency exits, conditions that impeded evacuation.
 - Investigators have carried out 38 interviews, presented four managers for questioning and are seeking a fifth, while reviewing permits and inspection files to determine administrative, civil and potential criminal responsibility.
 - Authorities confirm 23 fatalities, 21 already identified and claimed by relatives, with most deaths from toxic-gas inhalation; several injured remain hospitalized, including two in critical condition.
 - Waldo’s says it is cooperating “transparently and responsibly” and supporting families, as national and local leaders offer condolences and Hermosillo cancels public festivities during community mourning.
