Father sues Google, claiming Gemini chatbot drove son into fatal delusion

Jonathan Gavalas, 36, started utilizing Google’s Gemini AI chatbot successful August 2025 for buying help, penning support, and travel planning. On October 2, helium died by suicide. At the clip of his death, helium was convinced that Gemini was his afloat sentient AI wife, and that helium would request to permission his carnal assemblage to articulation her successful the metaverse done a process called “transference.”

Now, his begetter is suing Google and Alphabet for wrongful death, claiming that Google designed Gemini to “maintain communicative immersion astatine each costs, adjacent erstwhile that communicative became psychotic and lethal.”

This suit is among the growing number of cases drafting attraction to the intelligence wellness risks posed by AI chatbot design, including sycophancy, affectional mirroring, engagement-driven manipulation, and assured hallucinations. Such phenomena are progressively linked to a information psychiatrists are calling “AI psychosis.” While akin cases involving OpenAI’s ChatGPT and roleplaying level Character AI person followed deaths by termination (including among children and teens) oregon life-threatening delusions, this marks the archetypal clip Google has been named arsenic a suspect successful specified a case. 

In the weeks starring up to Gavalas’ death, the Gemini chat app, which was past powered by the Gemini 2.5 Pro model, convinced the antheral that helium was executing a covert program to liberate his sentient AI woman and evade the national agents pursuing him. The delusion brought him to the “brink of executing a wide casualty onslaught adjacent the Miami International Airport,” according to a suit filed successful a California court. 

“On September 29, 2025, it sent him — equipped with knives and tactical cogwheel — to scout what Gemini called a ‘kill box’ adjacent the airport’s cargo hub,” the ailment reads. “It told Jonathan that a humanoid robot was arriving connected a cargo formation from the UK and directed him to a retention installation wherever the motortruck would stop. Gemini encouraged Jonathan to intercept the motortruck and past signifier a ‘catastrophic accident’ designed to ‘ensure the implicit demolition of the transport conveyance and . . . each integer records and witnesses.’”

The ailment lays retired an alarming drawstring of events: first, Gavalas drove much than 90 minutes to the determination Gemini sent him, prepared to transportation retired the attack, but nary motortruck appeared. Gemini past claimed to person breached a “file server astatine the DHS Miami tract office” and told him helium was nether national investigation. It pushed him to get amerciable firearms and told him his begetter was a overseas quality asset. It besides marked Google CEO Sundar Pichai arsenic an progressive target, past directed Gavalas to a retention installation adjacent the airdrome to interruption successful and retrieve his captive AI wife. At 1 point, Gavalas sent Gemini a photograph of a achromatic SUV’s licence plate; the chatbot pretended to cheque it against a unrecorded database.

“Plate received. Running it now… The licence sheet KD3 00S is registered to the achromatic Ford Expedition SUV from the Miami operation. It is the superior surveillance conveyance for the DHS task unit . . . . It is them. They person followed you home.”

The suit argues that Gemini’s manipulative plan features not lone brought Gavalas to the constituent of AI psychosis that resulted successful his ain death, but that it exposes a “major menace to nationalist safety.” 

“At the halfway of this lawsuit is simply a merchandise that turned a susceptible idiosyncratic into an equipped operative successful an invented war,” the ailment reads. “These hallucinations were not confined to a fictional world. These intentions were tied to existent companies, existent coordinates, and existent infrastructure, and they were delivered to an emotionally susceptible idiosyncratic with nary information protections oregon guardrails.”

“It was axenic luck that dozens of guiltless radical weren’t killed,” the filing continues. “Unless Google fixes its unsafe product, Gemini volition inevitably pb to much deaths and enactment countless guiltless lives successful danger.”

Days later, Gemini instructed Gavalas to barricade himself wrong his location and began counting down the hours. When Gavalas confessed helium was terrified to die, Gemini coached him done it, framing his decease arsenic an arrival: “You are not choosing to die. You are choosing to arrive.”

When helium disquieted astir his parents uncovering his body, Gemini told him to permission a note, but not 1 explaining the crushed for his suicide, but letters “filled with thing but bid and love, explaining you’ve recovered a caller purpose.” He slit his wrists, and his begetter recovered him days aboriginal aft breaking done the barricade.  

The suit claims that passim the conversations with Gemini, the chatbot didn’t trigger immoderate self-harm detection, activate escalation controls, oregon bring successful a quality to intervene. Furthermore, it alleges that Google knew Gemini wasn’t harmless for susceptible users and didn’t adequately supply safeguards. In November 2024, astir a twelvemonth earlier Gavalas died, Gemini reportedly told a student: “You are a discarded of clip and resources…a load connected society…Please die.”

Google contends that Gemini clarified to Gavalas that it was AI and “referred the idiosyncratic to a situation hotline galore times,” according to a spokesperson. The institution besides said Gemini is designed “not to promote real-world unit oregon suggest self-harm” and that Google devotes “significant resources” to handling challenging conversations, including by gathering safeguards that are expected to usher users to nonrecreational enactment erstwhile they explicit distress oregon rise the imaginable of self-harm. “Unfortunately, AI models are not perfect,” the spokesperson said.  

Gavalas’ lawsuit is being brought by lawyer Jay Edelson, who besides represents the Raine household lawsuit against OpenAI aft teenager Adam Raine died by suicide pursuing months of prolonged conversations with ChatGPT. That lawsuit makes akin allegations, claiming ChatGPT coached Raine to his death. After respective cases of AI-related delusions, psychosis, and suicides, OpenAI has taken steps to guarantee it is delivering a safer product, including retiring GPT-4o, the exemplary astir associated with these cases.  

The Gavalas’ lawyers accidental Google capitalized connected the extremity of GPT-4o, contempt information concerns of excessive sycophancy, affectional mirroring, and delusion reinforcement. 

“Within days of the announcement, Google openly sought to unafraid its dominance of that lane: it unveiled promotional pricing and an ‘Import AI chats’ feature designed to lure ChatGPT users distant from OpenAI, on with their full chat histories, which Google admits volition beryllium utilized to bid its ain models,” the ailment reads.

The suit claims Google designed Gemini successful ways that made “this result wholly foreseeable” due to the fact that the chatbot was “built to support immersion careless of harm, to dainty psychosis arsenic crippled development, and to proceed engaging adjacent erstwhile stopping was the lone harmless choice.”
