A 17-year-old Indian-American boy, Arjun Aravind, has been charged with killing his mother, Sudha Venkatesan (45), and his younger brother, Siddharth Aravind (14), in Acton, a town about 40 kilometres northwest of Boston. The Middlesex District Attorney’s Office stated Arjun faces two counts of murder, two counts each of assault and battery on a household or family member and assault and battery, as well as charges of theft of a motor vehicle and use of a vehicle without authority. Police reached the family’s home on Martha Lane around 6.37 p.m. (local time) on Tuesday after Arjun’s father called, unable to reach his family. A tutor expected at the residence was also unable to contact anyone inside. Officials found Siddharth on the first floor and Venkatesan in the finished basement, both with visible trauma. Arjun was not present, and his mother’s green 2014 Honda Accord was missing. On Wednesday, police in Wayland responded to an unrelated alarm in a parking lot on Andrew Avenue, found the missing car with Arjun inside, and took him into custody without incident. The district attorney’s office said the investigation indicates Arjun had recently been using the Internet and ChatGPT to make searches for theoretical ideas or fantasies regarding killing his family. Prosecutors claimed Arjun fatally assaulted his mother and brother inside their home and later left in his mother
