Federal and state prosecutors charged a 20-year-old Texas man on Monday with attempted murder and explosives offenses in Friday's Molotov cocktail attack on OpenAI CEO Sam Altman's San Francisco home, San Francisco District Attorney Brooke Jenkins told reporters at a press briefing.
Daniel Alejandro Moreno-Gama, of Spring, Texas, allegedly traveled to San Francisco, threw a flaming bottle at the metal gate of Altman's Russian Hill residence around 3:45 a.m., then tried to batter his way into OpenAI's Mission Bay headquarters with a chair while carrying a kerosene jug, additional incendiary devices and a written list of AI industry executives, according to an FBI affidavit cited in court filings. Jenkins said the state counts alone could cost Moreno-Gama 19 years to life. Federal explosives charges carry a mandatory five-year minimum.
Key Takeaways
- Federal and state prosecutors charged Daniel Moreno-Gama, 20, of Spring, Texas, with two counts of attempted murder, explosives offenses, and possession of an unregistered firearm in Friday's Molotov attack on Sam Altman's San Francisco home.
- Court filings say Moreno-Gama carried a written document listing the names and home addresses of other AI company CEOs, board members, and investors, along with language about humanity's 'impending extinction.'
- After the Molotov attack, he traveled to OpenAI's Third Street headquarters, tried to break the glass with a chair, and told a security guard he had come to 'burn it down and kill anyone inside.'
- A second, apparently unrelated attack on Altman's Russian Hill home followed Sunday morning when a gunman in a passing car fired at the house; two more suspects are in custody.

Two stops, one night
The sequence laid out in court filings reads less like a flash of rage and more like a to-do list. A San Francisco Police Department report obtained by local outlets describes a hooded figure picking his way up Altman's Chestnut Street driveway in Russian Hill just before 3:45 a.m. Friday. Dark clothing. Backpack. He tossed the bottle at the gate. It landed up top, lit a small fire, and Altman's security team put it out before firefighters even showed up. Then he ran.
Less than an hour later, per the complaint, Moreno-Gama turned up at OpenAI's Third Street offices in Mission Bay. He grabbed a chair. Swung. The glass held. According to the federal affidavit, he told the building's security guard, when asked what he wanted, that he had come to "burn it down and kill anyone inside." By 5:07 a.m. officers were on scene, matching his face to the Chestnut Street footage. They cuffed him. In the backpack: more incendiary devices, a jug of kerosene, a blue lighter.
The document
What will define this case is not the fire. It is the piece of paper cops pulled off him. Federal prosecutors describe a written document that both claimed responsibility for trying to kill Altman and urged others to carry out similar acts. "If I am going to advocate for others to kill and commit crimes, then I must lead by example and show that I am fully sincere in my message," the document said, according to court records unsealed Monday.
Attached to that document: names and home addresses of other AI company CEOs, board members and investors. The same affidavit quotes Moreno-Gama writing about AI's risk to humanity and "our impending extinction." PauseAI, a Discord-based advocacy group that opposes frontier AI development, said Moreno-Gama joined its server two years ago. Discord banned him Monday for "off-platform behavior."
That detail will follow the AI safety movement into every security briefing held this week.

A blog post, then a second attack
Altman, who was not injured, posted Saturday on his personal blog. He called the fear surrounding artificial intelligence "justified." He shared a photograph of his husband and their son, something he described as out of character, in the hope that showing his family might dissuade the next person. "Images have power, I hope," he wrote.
The hope held for roughly 36 hours. Early Sunday, San Francisco police say, a car rolled to a stop outside the same Russian Hill address and one of its occupants fired a gun at the house. Two more suspects in custody. That incident remains under investigation and no link to Moreno-Gama has been alleged.
The security bill comes due
None of this is happening inside a vacuum. Physical security consultants have spent years warning that the industry's executives are uncommonly easy to locate. If you run a frontier AI company, your home address is probably already sitting in somebody's spreadsheet. "Altman has houses in Napa, Hawaii, San Francisco, maybe five or six houses, and every one of them are easy to get the full address. They're all on the internet," security expert Jeff Moyer told the San Francisco Standard. The hit list in Moreno-Gama's backpack suggests at least one person had already done the compiling.
FBI agents raided a home in Spring, Texas, linked to Moreno-Gama early Monday morning, FBI Director Kash Patel announced on social media. Moreno-Gama is scheduled for his first state court appearance Tuesday. A federal date has not been set. He is being held without bail.
What sits at the top of every frontier AI company's Monday night agenda now: fresh threat assessments, executive protection contracts, and the photograph of a husband and a son.
