The house at 1400 Donovan Street, in Resistencia, was the scene of an incident that ended with the death of Matías Julián Álvarez Guardia. According to the investigation, the young man suffered a deep stab wound to the chest during an argument with his partner, Victoria Luz Cantero.
After the assault, a friend rushed Matías to the Julio C. Perrando Hospital, where he underwent surgery. However, he died shortly afterward as a result of hypovolemic shock that led to a cardiac arrest.

Victoria Cantero, de 25 años, quedó detenida e imputada por homicidio. Durante su declaración, la joven dio una versión diferente de los hechos: aseguró que había recibido un llamado de un amigo para acercarse a la vivienda y que, al llegar, encontró a Matías herido sobre la vereda.
While justice works to reconstruct what happened that night and determine criminal responsibilities, the bond between them became central to the investigation.
A couple marked by ups and downs, according to Matías’ circle
According to the testimonies provided by relatives and acquaintances of the young man, the relationship between Matías and Victoria had undergone . According to those accounts, the couple had separated on several occasions and had recently resumed the relationship.
People close to Matías claim that during the relationship there had been episodes of violence directed at him. Among the events mentioned are alleged physical assaults, property damage and confrontations that would have generated concern among his circle.

According to relatives, Victoria would have broken the windshield of Matías’ car on one occasion, scratched it, and would also have participated in an argument during which she repeatedly struck the young man’s gate.
These testimonies form part of the context surrounding the investigation, though it will be up to the Justice system to determine what happened and what responsibilities correspond.
Who was Victoria Cantero before she became the focus of the investigation
Before the crime, Victoria Cantero showcased on her social networks a life linked to work, her family and everyday activities.

On her Facebook profile, she frequently shared images of the nail designs she created for clients and promoted her manicure business. She also posted personal moments, such as trips, gatherings with friends, and activities she enjoyed.
Among the most repeated images were photographs with her father and her brother, with whom she shared outings, fishing trips and strolls. There were also posts related to skating, one of her habitual activities.That content, which until recently formed part of her private life exposed on social media, is now viewed through a different lens in light of the case’s impact.
Victoria Cantero’s posts that drew attention after the crime
In addition to posts related to her everyday life, some of Victoria’s older posts began circulating after the incident and were subjected to public analysis.
In one of those posts appeared a line: “yo solo quiero amar y maltratar al mismo hombre el resto de mi vida”. In another she shared: “no entiendo a las que llevan un labubu en el bolso, yo llevaría una glock”, referring to a weapon.

There was also attention drawn to one of her latest posts, where she wrote: “Me van a funar, pero enseñar a tu hijo varón a servirse solo y recoger su desorden no es quitarle su masculinidad. Es evitar que sea el parásito emocional de su futura pareja”.
However, a social media post by itself does not constitute judicial proof. The prosecutor’s office will determine, together with the rest of the elements gathered in the case, what happened and what weight those expressions carry within the investigation.
A case that seeks to reconstruct what happened that night
The investigation remains open to reconstruct the sequence of events that culminated in Matías Álvarez Guardia’s death.
While Victoria Cantero remains charged, her defense argues a version different from the one presented by the victim’s family. In parallel, Matías’ relatives publicly expressed their demand for justice and insisted that the crime not go unpunished.
The case again shines a light on couples’ dynamics navigated by conflict, violence and situations that often stay private until a tragedy brings them into the public sphere.
