Authorities Arrest Adult Suspect in La Matanza Killing as La Plata Collision Is Reclassified

Investigators relied on CCTV data combined with virtual-wallet records to secure a key arrest in Buenos Aires province’s second fatal assault this week, highlighting digital evidence’s growing impact on criminal inquiries.

Overview

  • A 19-year-old suspect, Alex Uriel Muñoz, was detained after matching his clothing to security footage and tracing a virtual-wallet purchase following the Villa Luzuriaga carjacking that left Rita Mabel Suárez dead in front of her teenage son.
  • Police have identified two underage suspects, including 17-year-old Máximo José Leguizamón, who remain at large and whose cases will proceed through the juvenile-responsibility court system.
  • The La Matanza homicide investigation is now with the UFI Temática de Homicidios, where prosecutors have seized a Bersa .380 pistol and are awaiting ballistic results and the adult suspect’s first court appearance.
  • In La Plata, 83-year-old Manuel Coria’s death after being struck by an ESUR garbage truck was recategorized from “lesiones culposas” to “homicidio culposo,” and driver Walter Garay faces judicial scrutiny pending autopsy and vehicle-camera analysis.
  • These cases underscore a broader shift toward leveraging CCTV, digital-payment logs and in-vehicle cameras to accelerate suspect identification and strengthen prosecutorial evidence.
