Overview
- The Yellow Notice, published on November 18, 2025, circulates Vaca’s identity to member countries and border officers to aid location and verification.
- Vaca, a Córdoba native who had been living in Valencia, Spain, traveled to Asia in July 2022 and emailed in November 2022 that he was at a Laos monastery about 50 kilometers from China.
- Following that message, the email account stopped working and family attempts to contact him failed, with earlier emails showing contradictory details about his whereabouts and access to internet.
- Family inquiries and preliminary checks cast doubt on the claimed location and role, with no confirmed monastery at the stated point and reports that such institutions rarely employ foreign interpreters.
- Argentine authorities escalated the case through Interpol after family reports, Spanish checks found no movements for Vaca there, and investigators are seeking cooperation in the Laos–China region as relatives sustain public appeals.
