US man arrested as second suspect in Canada mass school shooting planned with ChatGPT

A surprise suspected accomplice has been arrested in connection with a mass school shooting in Canada that was made notorious after an 18-year-old allegedly killed six children after discussing it with the AI chatbot ChatGPT.

The US Department of Justice said on Tuesday it had detained James Codey Bryant, 30, a resident of western Washington state, on a charge of conspiracy to murder persons in a foreign country. Bryant offered money and “technical advice” to the suspected shooter for six months leading up to the killings, the justice department alleged. Canadian police have identified the suspect in this year’s massacre of eight people – including her mother and half-brother, as well as the six children, making it the second-deadliest school shooting in the country’s history – as Jesse Van Rootselaar, who has a history of mental health problems.

It had been known that Van Rootselaar had used ChatGPT to plan the attack, which took place in February. The safety team at OpenAI, the company that owns the chatbot, flagged Van Rootselaar internally after she conducted conversations with it about gun violence, but the company did not alert police.

OpenAI did reportedly close Van Rootselaar’s account, but she started a second one that was not closed. Victims’ families and the province of British Columbia have sued OpenAI and its CEO, Sam Altman, for failing to report her behaviour.
