Sena Clan Convicted to Life Imprisonment for Femicide of Cecilia Strzyzowski in Argentina

A popular jury in Argentina has delivered a landmark verdict, convicting the influential Sena clan to life imprisonment for the femicide of Cecilia Strzyzowski. The ruling, announced on November 15, 2025, found César Sena, the victim's partner, and his parents, Emerenciano Sena and Marcela Acuña, guilty of their respective roles in the crime that shocked the nation.

The Verdict and Sentences

After more than 10 hours of deliberation, the popular jury in Chaco Province unanimously found César Sena guilty as the author of aggravated homicide, specifically citing the aggravating circumstances of the relationship and gender-based violence. His parents, Emerenciano Sena and Marcela Acuña, were convicted as primary participants in the femicide, with the jury determining their involvement was indispensable for the crime to occur. All three received sentences of life imprisonment.

In addition to the core Sena family members, other individuals faced charges related to the cover-up of the crime:

• Gustavo Obregón and Fabiana González were found guilty of aggravated cover-up.
• Gustavo Melgarejo was convicted of simple cover-up.
• Griselda Reinoso was acquitted of all charges.

The Femicide of Cecilia Strzyzowski

Cecilia Marlene Strzyzowski, a 28-year-old woman, was last seen alive on June 2, 2023, entering the Sena family home in Resistencia, Chaco. Security footage captured her arrival, but there was no record of her ever leaving the property. Prosecutors alleged that Cecilia was murdered inside the house that same afternoon. Although her body has never been fully recovered, investigators found crucial forensic evidence, including dental fragments and burnt human remains, which were confirmed through analysis to belong to Cecilia. The investigation revealed that Cecilia had been led to believe she was traveling to Ushuaia with César Sena for a job opportunity, even packing a suitcase for the supposed trip.

The Sena Clan's Influence and Downfall

The Sena clan, comprising Emerenciano Sena and Marcela Acuña, were prominent social leaders in Chaco Province, known for their significant local political influence and strong ties to the provincial government. Their political connections and power amplified the shockwaves of Cecilia's disappearance and presumed murder, drawing national and international media attention, including from organizations like Amnesty International. The case had profound political repercussions in Chaco, contributing to a shift in the provincial political landscape. The trial, which began on October 28, 2025, was one of the most significant and high-profile in the province's history, highlighting the intersection of gender-based violence, local power, and political resonance.

The conviction of the Sena clan marks a significant moment in Argentina's ongoing fight against femicide and gender-based violence, underscoring the justice system's capacity to hold powerful figures accountable.
