On 2 June 2023, Cecilia Marlene Strzyzowski, a 28-year-old Argentine woman, went missing in Resistencia, Chaco. She was later found to have been murdered in an act of femicide. Among the main suspects and defendants are her partner, César Sena, along with his parents Emerenciano Sena and Marcela Acuña who were candidates in the 2023 provincial elections in Chaco Province. Sena and Acuña make up the "Sena Clan", a family of social leaders who have great local political influence as well as strong ties with the Government of Chaco Province, including then-current governor Jorge Capitanich. This case has attracted attention at the provincial and national level and has been reported in the main international media and by Amnesty International.

In addition to Sena, Gustavo Obregón and Fabiana Gonzáles, political leaders close to Acuña, were also charged; as well as Gustavo Melgarejo, the Senas' landlord, along with his partner Graciela Reynoso. The investigation was under the supervision of prosecutors Jorge Cáceres Olivera, Jorge Fernando Gómez and Nelia Vázquez of the Special Prosecutor's Office for Gender Violence No. 4 of the Public Prosecutor's Office.

The verdict was delivered on 15 November 2025. Six defendants were convicted of murder, while one, Graciela Reynoso, was found not guilty.
