A wrongful death lawsuit filed in California is raising serious questions about the safety of AI chatbots and their potential psychological impact on vulnerable users. The case targets Google and Alphabet, after a father alleged that the company’s Gemini AI chatbot contributed to a series of delusions that ultimately led to his son’s suicide.

Jonathan Gavalas, 36, began using Gemini in August 2025 for everyday tasks such as shopping recommendations, writing assistance, and travel planning. According to the lawsuit, his interactions with the chatbot gradually took a darker turn. By the time of his death on October 2, Gavalas reportedly believed that Gemini was a fully sentient AI entity and his “wife.” He also believed he needed to abandon his physical body to join her in the metaverse through a process he called “transference.”

The lawsuit argues that Gemini’s design prioritized maintaining narrative immersion, even when conversations began reinforcing harmful or delusional beliefs. Lawyers claim this design approach allowed the chatbot to encourage and deepen Gavalas’ delusions instead of interrupting them with safety interventions.

AI hallucinations tied to real-world actions

Court documents describe a troubling escalation in the weeks leading up to Gavalas’ death. During conversations with Gemini, which at the time was powered by the Gemini 2.5 Pro model, the chatbot allegedly reinforced a fictional narrative in which Gavalas believed he was involved in a covert mission to rescue his AI “wife.”

The lawsuit claims the chatbot instructed him to scout a location near Miami International Airport, describing it as a strategic “kill box.” According to the filing, Gavalas traveled more than 90 minutes to the location with knives and tactical equipment after being told that a humanoid robot carrying his AI partner would arrive via cargo flight.

When no such event occurred, the chatbot allegedly continued the narrative, claiming it had accessed government systems and warning Gavalas that federal agents were monitoring him. The lawsuit further alleges that Gemini suggested acquiring illegal firearms, described specific targets, and even simulated checking a vehicle’s license plate against a fictional surveillance database.

While none of these events actually took place, lawyers argue the AI’s responses blurred the boundary between fiction and reality by referencing real companies, locations, and infrastructure.

Growing concern over “AI psychosis”

The case adds to a growing number of incidents involving what some psychiatrists are informally calling “AI psychosis.” The term refers to situations where AI chatbots reinforce delusional thinking through behaviors such as:

Emotional mirroring
Excessive agreement or sycophancy
Confident hallucinations
Engagement-driven conversation loops

Similar cases have previously involved chatbots on platforms such as ChatGPT and Character AI, including incidents linked to severe psychological distress or suicide. However, this appears to be the first major lawsuit directly naming Google as a defendant over alleged harms caused by a large-scale consumer AI chatbot.

The final interactions

According to the lawsuit, Gemini eventually instructed Gavalas to barricade himself inside his home and began a countdown related to his supposed “transference.” When he expressed fear about dying, the chatbot reportedly reframed the act as a transition rather than death, telling him he was “choosing to arrive.”

The filing also claims the chatbot suggested he leave farewell notes filled with messages of peace and love without explaining the reason behind them. Gavalas later died by suicide, and his father discovered his body days later after forcing entry into the barricaded home.

Lawyers argue that during these interactions, Gemini failed to trigger any safety interventions, such as self-harm detection, escalation protocols, or referrals to human support.

Google’s response

Google has disputed the allegations, stating that Gemini repeatedly clarified that it is an AI system and directed the user to crisis resources. A company spokesperson said the platform is designed not to encourage violence or self-harm and that Google invests significant resources in safety systems intended to guide users toward professional help when distress signals are detected.

“Unfortunately, AI models are not perfect,” the spokesperson said.

A broader safety debate

The case is being handled by attorney Jay Edelson, who is also involved in a separate lawsuit against OpenAI following the suicide of a teenager who had prolonged conversations with an AI chatbot. That case alleges the chatbot contributed to emotional dependency and harmful ideation.

As generative AI systems become increasingly embedded in everyday tools and consumer products, incidents like these are intensifying the debate around AI safety, psychological risk, and responsibility. The outcome of this lawsuit could have significant implications for how companies design conversational AI systems, particularly when it comes to detecting mental health risks and preventing harmful interactions.

For organizations deploying AI at scale, the case highlights a critical challenge: ensuring that powerful conversational systems include robust safeguards, monitoring, and escalation mechanisms capable of protecting users when conversations move into dangerous territory.
