Background on the Incident and Key Parties Involved

More than three months after the explosion of a liquefied petroleum gas (LPG) tanker on the La Concordia bridge in Iztapalapa, Mexico City authorities presented updates on the case during a press conference led by Mayor Clara Brugada Molina. The incident, which occurred on September 10th, was determined to be caused by the loss of vehicle control while traveling at excessive speed on a raised curve, leading to tank fracture, gas leakage, and a large fire.

Investigation Findings

The Mexico City Fiscal General of Justice confirmed that the accident was not due to structural issues with the bridge, pre-existing mechanical problems in the vehicle, or adverse weather conditions. Instead, a thorough forensic investigation involving 16 specialties and over 270 technical reports pointed to the driver’s direct responsibility and omissions by the operating company related to operator training and supervision of driving hours, creating risky conditions.

Victims and Impact

According to the report, 32 people died, 63 were injured, eight suffered psychological sequelae, and 42 families and businesses experienced material damage, totaling 144 direct and indirect victims. All victims have been identified, including two initially unrecognized individuals who were reportedly homeless, through genetic analysis and collaboration with search institutions.

Reparations Agreement

A significant update was the signing of 143 reparation agreements worth a historical $480 million for such cases in the city. Approximately 90% of this amount, around $429 million, has already been paid to affected families. The funds have primarily gone to relatives of deceased individuals, injured persons, and other types of victims, while pending cases mainly involve material damages and succession or custody processes.

Medical Follow-up and Mental Health Attention

Mexico City’s Secretary of Health, Nadine Gasman Zylbermann, reported that the 52 hospitalized individuals continue to receive medical follow-up based on their needs, including physical rehabilitation, reconstructive surgery, and mental health care with support from institutions like IMSS, ISSSTE, IMSS-Bienestar, PEMEX, and the National Institute of Rehabilitation.

In terms of mental health, over 1,600 psychosocial attendances have been provided, and ongoing support is offered to direct victims and their families, acknowledging the medium- and long-term effects of the incident.

Preventive Measures and Non-Recurrence

To prevent similar incidents, the Mexico City government modified the Traffic Regulations to limit circulation hours for hazardous materials carriers, reduce maximum speeds to 30 km/h, and decrease permissible dangerous substance amounts. Additionally, an application for real-time monitoring of hazardous materials transport was announced, enabling citizen reports and tracking.

Authorities emphasized that the investigation remains open for pending cases and reaffirmed their commitment to transparency, comprehensive victim attention, and accountability.
