Overview
- A forensic autopsy concluded the child died from obstructive asphyxia causing hypoxemia and cardiac arrest, and authorities have kept the body for further histopathology and toxicology testing.
- Judicial authorities detained Lucía Sosa and formally imputed her for abandonment of a person followed by death aggravated by kinship after the autopsy shifted the inquiry from a medical accident to a criminal investigation.
- Prosecutors have summoned key witnesses, including Sosa’s 17‑year‑old son Lucas Ruiz, who publicly alleged past physical abuse and has been called to give testimony that could establish patterns of conduct.
- The couple’s surviving 4‑year‑old was removed to municipal protective custody and a Cámara Gesell interview is planned to secure the child’s account and assess risks to other children.
- Investigators are re‑examining two earlier infant deaths linked to Sosa (2013 and 2016) and prior expert notes that referenced possible Munchausen‑by‑proxy indicators, and the pending lab results and witness statements will be central to deciding whether the case is accidental, negligent, or criminal.
