Overview

• Neighbors say about ten pets were affected in a roughly three‑block area with at least three confirmed dog deaths and numerous dead birds reported.
• The Unidad Fiscal Especializada en Materia Ambiental (UFEMA) and fiscal Matías Hugo De Santis have opened a judicial investigation and are interviewing witnesses and reviewing nearby security cameras.
• Comisaría Vecinal 14B, Bomberos de la Ciudad and Espacio Público crews carried out on‑site inspections and hidrolavado/sanitization operations on targeted streets in Belgrano and Las Cañitas.
• Toxicology and forensic tests to identify the contaminant are still pending; journalists and residents have raised rodenticide (including possible strychnine) as a working hypothesis that has not been confirmed.
• Prosecutors have asked residents and merchants to submit phone videos, camera recordings and tips to UFEMA and the fiscalía, and veterinarians urge immediate care for animals with vomiting, tremors, convulsions or excessive salivation.
