Arjun Aravind, 17, faces two counts of murder after allegedly killing his mother, Sudha Venkatesan, 45, and brother, Siddharth Aravind, 14, in their Acton home. The crime was discovered when a tutor arrived for a scheduled appointment and found the door locked.12

Police were alerted by Arjun's father, who was unable to contact his family. Officers found the victims with "obvious trauma" inside the residence, with Sudha in the basement and Siddharth on the first floor.345

Authorities revealed that Arjun had fled the scene in his mother's car, a 2014 green Honda Accord, which was later located in Wayland, Massachusetts, where he was arrested without incident.78

Middlesex District Attorney Marian Ryan stated that the investigation indicated Arjun had been using the internet and ChatGPT to explore violent fantasies about killing his family, including creating "Gothic novel-kind of stories".611

In addition to murder charges, Arjun faces counts of assault and battery on a household member, unauthorized use of a vehicle, and theft of a motor vehicle. He will be arraigned in juvenile court for some charges and in district court for murder.

The exact cause and manner of death are pending investigation by the Chief Medical Examiner.

Ryan said that police had prior knowledge of Arjun from a runaway incident about a year ago, but there was little law enforcement involvement since then.10
