What the forensic report concluded
A technical assessment by the Directorate of Criminalistics and Forensic Studies of Argentina's National Gendarmería reached no definitive finding on whether recordings attributed to Diego Spagnuolo are genuine, and could not technically link the voices to the people charged in the case. The inquiry concerns alleged irregularities at the National Disability Agency, known as ANDIS. The specialists examined the clips that circulated during the investigation and listed technical and methodological limits that blocked a conclusive ruling on where the material came from.[S1][S2][S3]
According to the report, files that initially appeared suitable for analysis carried traits consistent with re-recording, a phenomenon the experts call acoustic transfer. The document also recorded abrupt discontinuities and acoustic inconsistencies that do not fit a continuous recording, features that could stem from cuts, interventions or editing carried out after the original capture. The specialists further stated that they could not rule out manipulation of the pieces or the use of artificial intelligence tools to alter or generate voices.[S1][S2][S3]
Why the chain of custody mattered
Preserving the chain of custody is essential to show that a file examined by experts is the same one originally obtained and that nothing changed while it circulated. In this case the report identified a break that occurred before the material reached the forensic stage, meaning the specialists had no guarantee the files had stayed untouched since their acquisition. That methodological gap shaped the conclusions on the recordings attributed to Spagnuolo, and the experts representing the parties in the proceedings agreed that the elements analyzed did not allow a definitive verdict on authenticity.[S1][S2]

How the recordings triggered the investigation
The probe began after the spread of audio clips ascribed to Spagnuolo that described an alleged scheme of collecting bribes from providers and pharmacies in connection with medicine purchases. One publicly known fragment referred to part of those funds as supposedly intended for Karina Milei, general secretary of the Presidency and sister of President Javier Milei. That mention helped drive the case forward, although Karina Milei was never charged in the file.[S1][S2][S3]
Spagnuolo's defense had argued that the material could have been edited or produced with artificial intelligence. On that basis the courts ordered the technical study of the files to see whether their origin could be established and to deepen the lines of inquiry. The case stays in the hands of federal judge Ariel Lijo, who must weigh the scope of the report and the pending evidentiary steps. The inability to authenticate the recordings does not by itself close the investigation into the alleged irregularities.[S1][S2][S3]
