Texas man charged in Molotov attack on OpenAI CEO Altman's home
A Texas man is charged with attempted murder and federal explosives offenses after allegedly attacking OpenAI CEO Sam Altman's San Francisco home with a Molotov cocktail on April 10, 2026.
Why it matters: Corporate legal and security teams face heightened risk as physical threats against AI leaders intensify. The rare dual prosecution underscores the need for robust threat assessment and security protocols in legal tech.
- Daniel Moreno-Gama, 20, allegedly threw a Molotov cocktail at Sam Altman’s San Francisco residence on April 10, 2026.
- He faces California state charges for attempted murder and arson, and federal charges for unregistered firearm possession and use of explosives.
- Police say Moreno-Gama traveled from Texas to California with documented anti-AI motives, then threatened OpenAI’s offices.
- FBI spokesperson Matt Cobo labeled the attack 'planned, targeted and extremely serious.'
Prosecutors in California and federal court have charged Daniel Moreno-Gama with multiple felonies following a Molotov cocktail attack on Sam Altman’s San Francisco residence early April 10, 2026. Police assert Moreno-Gama travelled from El Paso, Texas, carrying incendiary devices and a manifest voicing threats against AI executives.
- Authorities say Moreno-Gama ignited the exterior gate with a homemade incendiary device, then fled. Less than an hour later, he allegedly appeared at OpenAI’s headquarters, making further threats, according to the criminal complaint.
- Upon arrest, police seized a jug of kerosene, further incendiary components, and written threats specifically referencing artificial intelligence. The FBI’s Matt Cobo described the incident as “planned, targeted and extremely serious.”
- Moreno-Gama faces two counts of attempted murder and one of attempted arson in San Francisco Superior Court, and federal counts for possession of an unregistered firearm (the Molotov cocktail) and use of explosives to damage property, crimes carrying up to 30 years in federal prison. [Details]
The legal filings state Moreno-Gama’s motive was opposition to AI technology. Prosecutors emphasized the premeditation and cross-state nature, factors that triggered both state and federal jurisdiction.
Altman, who was unharmed, later called for ‘de-escalation’ in the AI debate. Anthony Aguirre, CEO of the Future of Life Institute, echoed that “violence and intimidation of any kind have no place in the conversation about the future of AI.” [Axios coverage]
The case sets a cautionary precedent for in-house counsel and legal operations leaders overseeing security policy for technology executives and firms.
By the numbers:
- April 10, 2026 — Date of the alleged attack on Altman’s residence.
- Up to 30 years — Maximum federal prison sentence for the explosives charges.
- Two — Number of separate attempted murder counts filed under California law.
Yes, but: Moreno-Gama is presumed innocent unless convicted in court; defense counsel has yet to publicly comment.
What's next: Moreno-Gama remains in custody pending separate hearings in state and federal court. Legal teams are reviewing physical security protocols for senior executives.
