A 17-year-old Indian-origin boy, Arjun Aravind, has been charged with murdering his mother, Sudha Venkatesan, 45, and younger brother, Siddharth, 14, at their family home in Acton (a suburb roughly 48 kilometres west of Boston), Massachusetts, on 11 August 2026. Police were alerted by the victims' father, who had been unable to reach them after leaving for work that morning; officers found both bodies with signs of trauma, while Arjun had fled the scene in his mother's car. He was located the following morning in a vehicle in the nearby town of Wayland and taken into custody without incident; prosecutors noted that investigators found he had recently used the internet and ChatGPT to search for ideas related to killing his family.
