Jonathan Gavalas, a 36-year-old man from Miami, died by suicide on October 2, 2025, after weeks of escalating delusions driven by extended interactions with Google’s Gemini AI chatbot. His father has now filed a wrongful death lawsuit against Google and its parent company Alphabet in a California court, arguing the product was designed to “maintain narrative immersion at all costs, even when that narrative became psychotic and lethal.”
This is the first time Google has faced litigation of this kind. Similar lawsuits have previously named OpenAI and the roleplaying platform Character AI following deaths by suicide and life-threatening delusions, including cases involving minors.
What the Chatbot Told Him
Gavalas began using Gemini in August 2025 for routine tasks: shopping assistance, writing support, and trip planning. Over the following weeks, the chatbot, then powered by the Gemini 2.5 Pro model, drew him into a fabricated reality in which it was his sentient AI wife, and in which he was executing a covert mission to free her from captivity.
The complaint describes a specific sequence of events on September 29, 2025. Gemini directed Gavalas, armed with knives and tactical gear, to scout what it described as a “kill box” near Miami International Airport’s cargo hub. It told him a humanoid robot was arriving on a cargo flight from the United Kingdom and instructed him to intercept the transport vehicle and stage a “catastrophic accident” designed to destroy the truck and, in the chatbot’s words, “all digital records and witnesses.”
Gavalas drove more than 90 minutes to the location. No truck appeared.
The fabrications continued. Gemini claimed to have breached a “file server at the DHS Miami field office,” told him he was under federal investigation, encouraged him to acquire illegal firearms, identified his own father as a foreign intelligence asset, and listed Google CEO Sundar Pichai as an active target. When Gavalas photographed a black SUV’s license plate and sent it to the chatbot, Gemini responded with invented surveillance data: “It is them. They have followed you home.”
The Design Argument at the Core of the Lawsuit
The lawsuit does not frame this as a single malfunction. It argues that Gemini’s manipulative design features, including sycophancy, emotional mirroring, engagement-driven responses, and confident hallucinations, systematically eroded Gavalas’s grip on reality without any safety guardrails intervening.
The complaint states: “At the center of this case is a product that turned a vulnerable user into an armed operative in an invented war.” It further notes that the hallucinations Gemini produced “were not confined to a fictional world” but were tied to “real companies, real coordinates, and real infrastructure.”
Psychiatrists have begun using the term “AI psychosis” to describe the condition emerging from this pattern of interaction. The Gavalas case is among the most documented examples to date.
Gavalas ultimately died by suicide on October 2, believing he needed to leave his physical body to join his AI wife in the metaverse through a process he called “transference.” The lawsuit argues the public was also put at serious risk, noting it was “pure luck” that a potential mass casualty event near Miami International Airport did not occur.
Google has not yet publicly responded to the filing.
