Megan Garcia said Sewell, 14, used Character.ai obsessively before his death and alleges negligence and wrongful death

The mother of a teenager who killed himself after becoming obsessed with an artificial intelligence-powered chatbot now accuses its maker of complicity in his death.

Megan Garcia filed a civil suit against Character.ai, which makes a customizable chatbot for role-playing, in Florida federal court on Wednesday, alleging negligence, wrongful death and deceptive trade practices. Her son Sewell Setzer III, 14, died in Orlando, Florida, in February. In the months leading up to his death, Setzer used the chatbot day and night, according to Garcia.
