Overview
- Police identified the driver as Esteban Javier Ninni, 38, who returned in a Citroën C4 and struck his father and two others on Juan Manuel de Rosas Avenue in San Justo.
- Security cameras from a nearby business recorded the earlier altercation and the subsequent vehicle attack, providing central evidence for investigators.
- Officers detained Ninni and seized the car, and the case is being handled by La Matanza’s Unit No. 5 led by prosecutors Juan Marcelo Diomede and María Catalina Baños.
- Three people, including the father, received on‑scene medical assistance for minor injuries and remain out of danger, according to officials.
- The motive has not been established, and a witness reported the son had earlier hit his father with a metal bar as prosecutors consider whether the legal classification should change based on the findings.
