Overview

• A security-camera image from September 6 shows Tony Janzen Valverde Victoriano, alias 'Pequeño J', walking with 15-year-old victim Lara Gutiérrez two weeks before the killings.
• Nine suspects are in custody across Argentina, Peru and Bolivia, and the lead prosecutor said additional arrest requests and raids are imminent.
• 'Pequeño J' remains in maximum-security isolation at the Cañete penitentiary in Peru as authorities weigh domestic prosecution versus extradition to Argentina.
• Forensic analysis of seized cellphones and fresh witness statements are helping investigators individualize roles; alleged lieutenant Matías Agustín Ozorio refused to testify.
• Prosecutors say a drug-related motive is unproven, noting that recent searches found no narcotics, while the victims were later discovered mutilated and buried in a Florencio Varela backyard.
