Cecilia Strzyzowski (28 years old) has been missing since June 1. She was last seen with her husband, César Sena, in Resistencia, Province of Chaco, Argentina. Her disappearance is being investigated as a femicide after possible human bones, blood traces and pieces of clothing were found at two properties belonging to Sena’s family who are powerful local leaders and were pre-candidates for the recent provincial elections.
