In early August 2026, Victoria Cantero was arrested in Resistencia, Chaco, and charged with aggravated homicide after her boyfriend, 29‑year‑old Matías Julián Álvarez Guardia, died from stab wounds. The initial report highlighted the violent history of the relationship, forensic evidence such as a kitchen knife, and the family’s demand for justice.

A few days later, prosecutors assembled a special fiscal team to deepen the inquiry. Cantero voluntarily gave the password to the victim’s mobile phone, allowing investigators to examine digital recordings, CCTV footage, and other forensic data. The team, led by prosecutors Ana González de Pacce and Martín Bogado, focused on reconstructing the events that began at a nightclub and continued at the victim’s home. Unresolved issues—including the possible involvement of third parties and the location of a missing evidence box—were noted, indicating that the investigation remained ongoing.
