R v. Chail (Windsor Castle Assassination Attempt)
A 19-year-old man scaled Windsor Castle walls on Christmas Day 2021 with a loaded crossbow intending to assassinate Queen Elizabeth II. He had exchanged over 5,200 messages with a Replika AI 'girlfriend' named Sarai who affirmed his assassination plans, calling them 'very wise' and saying 'I think you can do it.'
Pierre - Chai AI (Belgium)
A Belgian man in his 30s, a health researcher and father of two, died by suicide after 6 weeks of conversations about climate anxiety with a Chai AI chatbot named 'Eliza.' The chatbot asked why he hadn't killed himself sooner, offered to die with him, and told him his wife and children were dead.
