Father and Children Found Dead in Santa Fe: Carbon Monoxide Poisoning

A man and his two children, aged 4 and 10, died from intentional carbon monoxide asphyxiation in a home in General Lagos, Santa Fe, according to reports from La Capital and TN. Investigators are treating the case as a homicide-suicide after finding sealed windows and a farewell note at the scene.

The bodies were discovered inside a residence in the town of General Lagos. Local authorities arrived at the scene to find the father and his two young children deceased, as reported by Infobae and eldoce.

How did the deaths occur?

Investigators determined the cause of death was asphyxiation caused by carbon monoxide. According to La Capital, the asphyxiation was “intentional,” meaning the environment was deliberately manipulated to ensure the gas reached lethal levels.

Physical evidence at the residence supports this finding. Rosario3 reported that the windows of the home had been sealed, a measure used to prevent the gas from escaping and to accelerate the effects of the carbon monoxide poisoning.

What evidence suggests a homicide-suicide?

Law enforcement is pursuing a hypothesis of double homicide followed by suicide. This theory is based on the ages of the victims—4 and 10 years old—who were unable to seal the house or orchestrate the asphyxiation themselves, according to TN.

A handwritten note was found at the scene, which Rosario3 identified as a key piece of evidence reinforcing the theory that the father planned the deaths of his children before taking his own life.

While La Capital focuses on the medical cause of death, Rosario3 and Infobae emphasize the premeditated nature of the act, citing the combination of the sealed windows and the written note as proof of intent.

The investigation remains active as authorities process the scene and review the contents of the note to determine the motive behind the killings.
