The case of little Isabella Aguirre (2), who passed away on July 21, 2026 in Villa Gesell (a popular Atlantic coastal resort city in Argentina), continues to progress through the justice system. This Tuesday, July 28, Lucía Sosa (44) refused to testify during her formal interrogation before prosecutor Juan Pablo Calderón, following her defense team's recommendation.
Currently, the woman is charged with abandonment of a person followed by death, aggravated by the bond, a crime that carries a maximum penalty of 20 years in prison. However, according to reports by TN and Infobae, the prosecution is evaluating changing the legal classification to aggravated homicide due to the bond. Under Argentine law, killing a direct descendant is a severe aggravating factor that carries a sentence of life imprisonment (prisión perpetua).
The autopsy report was key in directing the investigation. Although Sosa had claimed the baby bronchoaspirated (inhaled liquid into her lungs) while drinking from a baby bottle, the forensic study determined the death was the result of obstructive asphyxia. This caused severe hypoxemia (a lack of oxygen in the blood) that led to cardiorespiratory arrest. The medical team attempted to resuscitate her for 40 minutes without success.
José Daniel Aguirre (53), Sosa's partner and Isabella's father, defended the woman in statements to La Nación. The man maintained that the tragedy was an accident and that he had never witnessed any abuse. He stated he found the girl unconscious upon returning from work and was unaware of his partner's past.
In contrast, Lucas Ruiz (17), Sosa's son from a previous relationship, reported his mother and asked for her to be imprisoned or placed in a psychiatric facility. The teenager, who is scheduled to testify on July 29, recounted situations of abuse and stated he knew that if the woman was not institutionalized, it would happen again.
The case reopened a file that shocked the Argentine coast in 2018, when Sosa was acquitted in a trial for the deaths of two of her previous daughters: Candela (6 months) in 2013 and Yazmín (11 months) in 2016. At that time, the deaths were attributed to respiratory complications.
Years after her acquittal, Sosa was reportedly diagnosed with signs of Munchausen Syndrome by Proxy. This is a severe psychiatric disorder where a caregiver intentionally feigns or induces illness in a person under their care, usually to gain attention and sympathy. The prosecution is now awaiting the results of toxicological, histopathological, and psychiatric studies to determine Sosa's criminal responsibility and the definitive direction of the case.
Sosa's 4-year-old son with Aguirre has been placed under the custody of child protection agencies, and the father has expressed his intention to regain custody. The Justice system continues to work to clarify the facts and ensure the safety of the minors involved.
