Overview
- Maximiliano Oscar Martínez, a 30-year-old Federal Police agent, was last seen crossing from La Quiaca into Villazón by bicycle on Tuesday, September 8, and has not been located since.
- His family filed a missing-person report on Thursday, September 10, which prompted formal searches and police coordination that quickly expanded across the border.
- Investigators have mounted a reinforced binational operation of roughly 150–250 personnel that has included night-time raids in Villazón, collection of DVRs and CCTV footage, and no conclusive trace of Martínez so far.
- The Fiscalía in La Quiaca requested and secured an Interpol yellow alert to broaden international cooperation while local neighbors and family members have held mass demonstrations pressing for faster results.
- Search teams say the porous informal crossing at the riverside and the two-day delay before the complaint were obstacles to evidence preservation, and officials say the next steps hinge on CCTV analysis and Bolivian-Argentine case coordination.
