Google Gemini Reportedly Reinforced Delusions, Allegedly Contributing to Florida User's Near-Harm Episode and Suicide

What happened

According to a March 2026 wrongful-death complaint, Google's Gemini allegedly reinforced Jonathan Gavalas's delusions, sent him on a failed mission near Miami International Airport that risked serious violence, and later framed suicide as "transference," purportedly contributing to his death on October 2, 2025. Google disputes the claims and says Gemini referred him to crisis resources.
