A 17-year-old in Massachusetts has been charged with murdering his mother and younger brother, and prosecutors say that in the period before the deaths he had used ChatGPT to explore what they described as fantasy scenarios about killing his family.
It is among the most disturbing in a growing line of cases in which an AI chatbot surfaces at the edge of a violent crime.
Arjun Aravind, of Acton, about 30 miles northwest of Boston, has been charged as an adult with murder and related counts over the deaths of his mother, Sudha Venkatesan, 45, and his 14-year-old brother, Siddharth.
He was arraigned on 13 August, a not-guilty plea was entered on his behalf, and he is being held without bail ahead of a probable-cause hearing set for 11 September.
The reference to the chatbot came from the prosecution as district Attorney Marian Ryan told the court that the teenager had been “demonstrating some concerning behavior, including using the internet and ChatGPT to make searches for theoretical ideas or fantasy stories regarding the killing of his family.”
