Overview
- The Legislatura sanctioned Law 6956 on Monday, June 29, 2026, creating the Registro de Perfiles Genéticos and repealing the 2011 Law 4.114.
- Implementation is placed under the Ministerio Público Fiscal de la Ciudad and the registry will cross DNA from crime scenes with stored profiles to link investigations and identify suspects.
- The law expands coverage to all crime types, allows collection from people under investigation with a court order, and requires voluntary profiles from police, forensic staff and officials to detect contamination.
- Officials say the system will use only non‑coding DNA, adopt the international CODIS standard, and cites Mendoza’s decade‑long registry which, government papers claim, yields matches in seven of ten traces and shows many identified suspects were already in that database.
- The government says access will be logged, audits will run, profiles will be deleted after a final acquittal, and the current coverage notes no published implementation timetable or independent oversight responses so far.
