Overview
- The girl's father filed a missing‑person report on August 25, 2023, and the case was moved to the federal Unidad Fiscal Santa Fe after provincial authorities declared themselves incompetent in September 2024.
- Interpol published a yellow notice in May 2026 to alert other countries and help locate 5‑year‑old Mía Guadalupe Salteño Altamirano.
- Federal prosecutors say digital forensics including Meta account data and DATIP IP georeferencing produced access records tied to multiple countries, with activity linked to Venezuela and Brazil's Mato Grosso do Sul.
- Official checks by Argentina’s migration and transport agencies found no formal entries or interurban travel records for the child, her mother Fiorella Abigail Salteño, or the mother's partner, which investigators say raises the likelihood of an irregular border crossing.
- The Unidad Fiscal has requested cooperation and information from Brazilian and Venezuelan authorities plus Venezuelan firms such as DIGITEL and the Education Ministry, and is asking the public to provide tips via a WhatsApp line and email as it continues witness follow‑up and technical tracing with the child's welfare as the priority.
