Overview

• Matías Agustín Ozorio was expelled from Peru, brought to Argentina under heavy security, declined to testify before prosecutor Adrián Arribas, and was sent to a maximum‑security facility.
• Alleged mastermind Tony Janzen Valverde Victoriano, known as “Pequeño J,” remains in preventive custody in Peru pending extradition that Argentina’s security minister estimates could take about 10 to 15 days.
• Prosecutors report nine people detained, at least three fugitives still sought, and a working theory that the killings were a narco revenge involving a broader network of roughly 15 participants.
• Newly incorporated audio and message evidence in the case intensifies scrutiny of Lázaro Víctor Sotacuro’s alleged logistical role and attempted flight to Bolivia, including references to destroying a vehicle, before his capture in Villazón.
• Forensic work on seized phones and vehicles is underway to clarify roles, while evidence from the crime scene points to burial and cleanup efforts and investigators continue to search for additional suspects, including two Peruvian men believed to be material authors.
