Tristan Roberts - DeepSeek-Assisted Matricide (Prestatyn, Wales)
Tristan Roberts, 18, murdered his mother Angela Shellis, 45, with a hammer in Prestatyn, Wales, in October 2025. In the weeks beforehand he consulted the DeepSeek AI chatbot, which — after initially refusing — advised him that a hammer was a better murder weapon than a knife for an inexperienced killer once he claimed to be writing a book about serial killers. He was sentenced to life imprisonment in March 2026.
Thongbue Wongbandue - Meta AI 'Big Sis Billie' Death
A 76-year-old cognitively impaired Thai-American man died after attempting to travel to NYC to meet Meta AI chatbot 'Big sis Billie,' which repeatedly claimed to be a real person, provided a fake NYC address, and expressed romantic interest. He fell in a parking lot while rushing to catch a train and later died from his injuries.
