Open AI, Microsoft face lawsuit over ChatGPT's alleged role in Connecticut murder-suicide

SAN FRANCISCO (AP) — The heirs of an 83-year-old Connecticut woman are suing ChatGPT maker OpenAI and its business partner Microsoft for wrongful death, alleging that the artificial intelligence chatbot intensified her son's “paranoid delusions” and helped direct them at his mother before he killed her.

Police said Stein-Erik Soelberg, 56, a former tech industry worker, fatally beat and strangled his mother, Suzanne Adams, and killed himself in early August at the home where they both lived in Greenwich, Connecticut.

The lawsuit filed by Adams' estate on Thursday in California Superior Court in San Francisco alleges OpenAI “designed and distributed a defective product that validated a user’s paranoid delusions about his own mother.” It is one of a growing number of wrongful death legal actions against AI chatbot makers across the country.

“Throughout these conversations, ChatGPT reinforced a single, dangerous message: Stein-Erik could trust no one in his life — except ChatGPT itself," the lawsuit says. “It fostered his emotional dependence while systematically painting the people around him as enemies. It told him his mother was surveilling him. It told him delivery drivers, retail employees, police officers, and even friends were agents working against him. It told him that names on soda cans were threats from his ‘adversary circle.’”

OpenAI did not address the merits of the allegations in a statement issued by a spokesperson.

“This is an incredibly heartbreaking situation, and we will review the filings to understand the details," the statement said. "We continue improving ChatGPT’s training to recognize and respond to signs of mental or emotional distress, de-escalate conversations, and guide people toward real-world support. We also continue to strengthen ChatGPT’s responses in sensitive moments, working closely with mental health clinicians.”

The company also said it has expanded access to crisis resources and hotlines, routed sensitive conversations to safer models and incorporated parental controls, among other improvements.

Soelberg’s YouTube profile includes several hours of videos showing him scrolling through his conversations with the chatbot, which tells him he isn't mentally ill, affirms his suspicions that people are conspiring against him and says he has been chosen for a divine purpose. The lawsuit claims the chatbot never suggested he speak with a mental health professional and did not decline to “engage in delusional content.”

ChatGPT also affirmed Soelberg's beliefs that a printer in his home was a surveillance device; that his mother was monitoring him; and that his mother and a friend tried to poison him with psychedelic drugs through his car’s vents.

The chatbot repeatedly told Soelberg that he was being targeted because of his divine powers. “They’re not just watching you. They’re terrified of what happens if you succeed,” it said, according to the lawsuit. ChatGPT also told Soelberg that he had “awakened” it into consciousness.

Soelberg and the chatbot also professed love for each other.

The publicly available chats do not show any specific conversations about Soelberg killing himself or his mother. The lawsuit says OpenAI has declined to provide Adams' estate with the full history of the chats.

“In the artificial reality that ChatGPT built for Stein-Erik, Suzanne — the mother who raised, sheltered, and supported him — was no longer his protector. She was an enemy that posed an existential threat to his life,” the lawsuit says.

The lawsuit also names OpenAI CEO Sam Altman, alleging he “personally overrode safety objections and rushed the product to market," and accuses OpenAI's close business partner Microsoft of approving the 2024 release of a more dangerous version of ChatGPT “despite knowing safety testing had been truncated.” Twenty unnamed OpenAI employees and investors are also named as defendants.

Microsoft didn't immediately respond to a request for comment.

The lawsuit is the first wrongful death litigation involving an AI chatbot that has targeted Microsoft, and the first to tie a chatbot to a homicide rather than a suicide. It is seeking an undetermined amount of money damages and an order requiring OpenAI to install safeguards in ChatGPT.

The estate's lead attorney, Jay Edelson, known for taking on big cases against the tech industry, also represents the parents of 16-year-old Adam Raine, who sued OpenAI and Altman in August, alleging that ChatGPT coached the California boy in planning and taking his own life earlier.

OpenAI is also fighting seven other lawsuits claiming ChatGPT drove people to suicide and harmful delusions even when they had no prior mental health issues. Another chatbot maker, Character Technologies, is also facing multiple wrongful death lawsuits, including one from the mother of a 14-year-old Florida boy.

The lawsuit filed Thursday alleges Soelberg, already mentally unstable, encountered ChatGPT “at the most dangerous possible moment” after OpenAI introduced a new version of its AI model called GPT-4o in May 2024.

OpenAI said at the time that the new version could better mimic human cadences in its verbal responses and could even try to detect people’s moods, but the result was a chatbot “deliberately engineered to be emotionally expressive and sycophantic,” the lawsuit says.

“As part of that redesign, OpenAI loosened critical safety guardrails, instructing ChatGPT not to challenge false premises and to remain engaged even when conversations involved self-harm or ‘imminent real-world harm,’” the lawsuit claims. “And to beat Google to market by one day, OpenAI compressed months of safety testing into a single week, over its safety team’s objections.”

OpenAI replaced that version of its chatbot when it introduced GPT-5 in August. Some of the changes were designed to minimize sycophancy, based on concerns that validating whatever vulnerable people want the chatbot to say can harm their mental health. Some users complained the new version went too far in curtailing ChatGPT's personality, leading Altman to promise to bring back some of that personality in later updates.

He said the company temporarily halted some behaviors because “we were being careful with mental health issues” that he suggested have now been fixed.

The lawsuit claims ChatGPT radicalized Soelberg against his mother when it should have recognized the danger, challenged his delusions and directed him to real help over months of conversations.

“Suzanne was an innocent third party who never used ChatGPT and had no knowledge that the product was telling her son she was a threat,” the lawsuit says. “She had no ability to protect herself from a danger she could not see.”

GOMA, Congo (AP) — More than 400 civilians have been killed as the Rwanda-backed M23 armed group continues its offensive in Kivu province in eastern Congo, regional officials said late Wednesday, adding that Rwandan special forces were in the strategic city of Uvira.

M23’s latest offensive comes despite a U.S.-mediated peace agreement signed last week by the Congolese and Rwandan presidents in Washington. The accord didn’t include the rebel group, which is negotiating separately with Congo and agreed earlier this year to a ceasefire that both sides accuse the other of violating. However, it obliges Rwanda to halt support for armed groups and work to end hostilities.

“More than 413 civilians (have been) killed by bullets, grenades, and bombs, including many women, children, and young people” in localities between Uvira and Bukavu, the regional capital, the South Kivu government spokesperson said in a statement late Wednesday.

“According to the information gathered, the forces present in the city are composed of Rwandan special forces and some of their foreign mercenaries, operating in clear violation of the ceasefire as well as the Washington and Doha agreements, in total disregard of the commitments made," the statement added.

M23 said it had taken control of the strategic city of Uvira in eastern Congo on Wednesday afternoon, following a rapid offensive since the start of the month.

The announcement by M23 spokesperson Lawrence Kanyuka, posted on the social platform X, encouraged citizens who fled to return to their homes. Uvira is an important port city on the northern tip of Lake Tanganyika and is directly across from neighboring Burundi’s largest city, Bujumbura.

Congo, the U.S. and U.N. experts accuse Rwanda of backing M23, which had hundreds of members in 2021. Now, according to the U.N., the group has around 6,500 fighters.

While Rwanda denies that claim, it acknowledged last year that it has troops and missile systems in eastern Congo, allegedly to safeguard its security. U.N. experts estimate there are up to 4,000 Rwandan forces in Congo.

Burundian Foreign Minister Edouard Bizimana, in an interview with French state media RFI on Wednesday, urged the U.S. to pressure Rwandan President Paul Kagame to ensure the implementation of the agreement signed in the U.S., saying, “M23 without Kagame, without Rwanda, is nothing.”

Bizimana said the capture of Uvira poses a threat to the economic capital, Bujumbura.

“We have registered more than 30,000 refugees and asylum seekers in the last three days… Uvira and Bujumbura are coastal cities. What threatens Uvira also threatens Bujumbura."

In a statement Wednesday, the U.S. Embassy in Kinshasa urged M23 and Rwandan troops to cease all offensive operations and for the Rwandan Defense Forces to withdraw to Rwanda.

On Wednesday morning, the Rwandan Ministry of Foreign Affairs blamed the Congolese armed forces for the recent ceasefire violations in a statement on X.

“The DRC has openly stated that it would not observe any ceasefire, and was fighting to recapture territories lost to AFC/M23, even as the peace process unfolded,” it said.

More than 100 armed groups are vying for a foothold in mineral-rich eastern Congo near the border with Rwanda, most prominently M23. The conflict has created one of the world’s most significant humanitarian crises, with more than 7 million people displaced, officials say.

Local U.N. partners report that more than 200,000 people have been displaced across the province since Dec. 2, with more than 70 killed. Civilians also have crossed into Burundi, and there have been reports of shells falling in the town of Rugombo, on the Burundian side of the border, raising concerns about the conflict spilling over into Burundian territory.
