Overview
- Maximiliano Oscar Martínez, a 30-year-old agent of the Argentine Federal Police, was last seen crossing into Villazón after Tuesday's security footage showed him using an unauthorized river crossing near Calle Jujuy.
- His family filed a formal missing-person complaint with provincial police on Thursday, September 10, which activated official search protocols and greater judicial coordination.
- Fiscal Alberto Mendívil is leading a large-scale search that now involves roughly 150–250 personnel from provincial police, Policía Federal, Gendarmería and other agencies working jointly with Policía Boliviana.
- The Fiscalía activated an Interpol yellow alert to broaden international data-sharing and investigators carried out nighttime allanamientos in Villazón with Argentine observers, but those raids have not produced confirmed leads.
- Neighbors and Martínez's parents have held public marches calling for his appearance alive and authorities have asked the public to report tips to 911, 388-6860239 or 388-6828607 as the binational operation continues.
