Overview

• The Sept. 6 security video recorded in Buenos Aires’ Flores neighborhood shows Tony Janzen Valverde Victoriano with Lara Gutiérrez days before the murders, a meeting the lead prosecutor says is now in the case file.
• Peruvian forensic experts produced a psychological report describing the suspect with psychopathic and antisocial traits, marked narcissism, manipulative capacity and aggressiveness.
• Valverde Victoriano remains in preventive detention at Cañete prison in Peru while extradition is processed, whereas his alleged lieutenant, Matías Agustín Ozorio, has already been transferred to Argentine custody.
• A new material suspect known as “El Loco David” or “Tarta” emerged from detainee and witness statements as a possible hitman in the attacks, with investigators probing his ties to vehicles and movements cited in testimony.
• Prosecutors continue forensic and digital analysis, including seized phones, as they pursue leads tied to a Peru‑Argentina drug network that allegedly trafficked “Tusi” and may have had prior contact with the victims.
