Overview

• Investigators reported the tanker entered the La Concordia curve at 44 km/h where the limit is 40, struck concrete barriers, fractured the tank and released gas that formed a 180‑meter cloud before igniting.
• Per forensic reviews, the tractor-trailer and its valves showed no pre-crash mechanical failures and the roadway showed no defects, pointing to the human factor as the immediate cause.
• Records cited by prosecutors indicate the driver had multiple high-speed incidents earlier that day, drove 6 hours 20 minutes with only a 15‑minute break, accumulated 16 hours in 24, lacked a pre-trip medical exam and had insufficient training.
• Officials said company omissions in risk management are under review and, absent a reparation agreement with victims, they have elements to seek charges against Silza for negligent homicide, injuries and property damage.
• Authorities confirmed 31 deaths, 59 injuries with 44 discharged and 9 still hospitalized, and said the case file is reserved for three years as families report no indemnities yet from Tomza or its insurers despite initial promises.
