Overview

• Thousands marched in Buenos Aires on Saturday, with families and feminist groups demanding justice and denouncing what they called a narco-feminicide.
• Police say the victims — Morena Verdi, Brenda del Castillo and 15-year-old Lara Gutierrez — were lured into a van on September 19 and found buried five days later in a southern suburb.
• Authorities report the attack was recorded and viewed by a private audience and say a detainee led police to the video, though attribution to Instagram is disputed by the platform.
• Five suspects are in custody, including one detained in Villazon, Bolivia, while a 20-year-old Peruvian identified by police as the alleged ringleader remains at large after his photo was released.
• Investigators link the murders to a drug-trafficking gang that sought to punish alleged rule-breaking, with Argentine media reporting extreme torture before the killings.
