Overview
- A technical peritaje by the Dirección de Criminalística y Estudios Forenses of Gendarmería Nacional concluded on October 29, 2026 that it could not verify the authenticity of the audios attributed to former ANDIS chief Diego Spagnuolo.
- Examiners identified abrupt cuts, acoustic discontinuities and features compatible with re‑recording, a pattern known as transferencia acústica, which suggests edits or post‑capture interventions to the files.
- The experts also reported interruptions in the chain of custody before the material reached specialists, a preservation failure that prevented secure linkage between the analyzed files and the originals.
- Peritos did not rule out manipulation or the use of artificial‑intelligence tools to alter or synthesize voices, a possibility raised by Spagnuolo's defense that prompted the technical analysis.
- The audios originally triggered a probe into alleged kickbacks in ANDIS that included a fragment naming Karina Milei, and the report’s limits mean Judge Ariel Lijo must now weigh new forensic methods or other evidence as the investigation continues.
