A History of Silenced Violence

The victim's family, through statements from his sister Noelia Guardia, described a relationship of more than two and a half years marked by jealousy, control, and physical violence. They claim that Cantero entered the house in the early morning using a copy of the keys and attacked Matías while he was asleep.

He was killed while sleeping. He didn't have time to defend himself. She has knowledge because her father is a doctor, and the stab wound was precise.

The family also reported that Matías had previously filed complaints and requested a restraining order that was never granted. They recounted episodes where the accused broke his phones and even damaged his truck with a brick.

Chilling Social Media Posts

After the crime, old posts on the accused's Facebook profile gained attention. In December 2025, Cantero allegedly wrote phrases like 'I just want to love and mistreat the same man for the rest of my life' and 'I don't understand women who carry a Labubu in their purse, I would carry a Glock'. Her social media accounts were closed on the afternoon of Monday, August 3.

The Defense's Argument

Defense attorney Marco Molero described his client as 'sorrowful' and denied she had any criminal record. In her initial statement, Cantero claimed she was called by a friend and arrived to find her boyfriend already wounded on the sidewalk. The defense is considering the possibility that the attack was a 'defensive maneuver' in response to a prior aggression, something the prosecution refutes with collected testimonies.

Hope for Justice

While the pain overwhelms Matías's family, the progress of the investigation offers a path toward truth and justice. Cases like this invite society to reflect on the importance of reporting any form of domestic violence, regardless of the gender of the aggressor or victim, and to trust institutions to clarify the facts. In Argentina, the 144 hotline provides free, confidential support 24/7 for victims of gender-based violence.
