Overview

• Authorities say an account on Zangi was created around 11 p.m. on September 19 and about 40 users connected to a live transmission tied to the killings.
• Investigators report one participant may have recorded the stream on a separate phone, creating a potential evidentiary trail outside the app.
• Three victims — Morena Verdi, Brenda del Castillo and Lara Gutiérrez — were found on September 24 in a house in Florencio Varela, where four suspects were detained.
• Sources identify Tony Janzen Valverde Victoriano, known as “Pequeño J,” as a principal suspect linked to organizing the crime and the warning message shared with viewers.
• Zangi, an Armenian-origin app launched in 2013, uses peer-to-peer encryption and low data consumption, has been tied to groups such as Los Menores and Tren de Aragua, and was misidentified earlier by a provincial security official.
