Overview
- Police and firefighters unearthed the body of 54-year-old lawyer and ex‑Morón councillor Graciela Martínez in the backyard of her Castelar home after a judicial search prompted by a civilian tip.
- Her adult son, Carlos Ignacio Costa Martínez, is the principal suspect and was already detained after an alleged knife attack on his father that left the father hospitalized.
- While held on the attempted‑murder charge, the suspect reportedly confessed the killing to a friend, who then informed authorities and led to the urgent court order to search the property.
- Investigators say the body was wrapped in plastic bags and buried in the rear yard; the case is now handled by UFI N°1 de Morón under fiscal Javier María Ghessi and is labeled homicidio calificado por el vínculo.
- Neighbors describe Martínez as a devoted mother and respected local lawyer, and authorities say forensic analysis and evidence-gathering will focus next on confirming the timing, motive, and sequence of events.
