Overview

• Two stepbrothers, aged 14 and 16, fatally stabbed their stepfather during a violent assault on their mother in Las Heras, Mendoza, early Monday morning.
• The 16-year-old has been charged with simple homicide, while the 14-year-old, deemed legally unimputable due to his age, is under the supervision of an interdisciplinary state team (ETI).
• The victim, initially identified as Joaquín Osvaldo Soto, was later revealed to be Francisco David Lescano Aguirre, who had used a false identity for over a decade, evading detection by multiple state systems.
• Authorities are investigating whether the brothers acted in legitimate defense to protect their mother from ongoing domestic violence and are determining each boy's specific role in the stabbing.
• The victim had a criminal history including homicide, armed robbery, drug trafficking, and gender-based violence, raising questions about systemic failures in monitoring his activities.
