Texas Man Charged with Attempted Murder in Molotov Attack on Sam Altman

A 20-year-old man from Texas faces multiple charges of attempted murder after authorities say he traveled to San Francisco with a manifesto calling for the deaths of leading AI executives, threw a Molotov cocktail at OpenAI CEO Sam Altman’s home, and then threatened to burn down the company’s headquarters while declaring he would kill everyone inside.

Daniel Moreno-Gama was arrested shortly after the early-morning incidents on April 10 and was charged Monday in both federal and California state courts. The case shines an uncomfortable light on the escalating public alarm over unchecked artificial intelligence development, even as powerful tech leaders like Altman continue to accelerate the very systems many experts warn could pose existential risks to humanity.

According to a federal criminal complaint, Moreno-Gama approached Altman’s North Beach residence at approximately 3:37 a.m., lit and hurled an incendiary device at the front gate, and fled on foot. Surveillance footage captured the attack. Less than an hour later, he allegedly arrived at OpenAI’s offices in Mission Bay, struck the glass entrance with a chair, and told security staff he intended to torch the building and murder those inside. Police recovered a jug of kerosene, a lighter, and a three-part document from him upon arrest.

That document, described in court filings as a manifesto titled in part “Your Last Warning,” explicitly identified Moreno-Gama as its author. It warned of AI’s purported risk to humanity and “our impending extinction,” listed names and addresses of other AI company CEOs and major investors, and advocated violence against them. One section called for the killing of Altman specifically and urged others to follow suit. Authorities described the actions as premeditated, not spontaneous.

“This was not spontaneous. This was planned, targeted and extremely serious,” said FBI San Francisco Acting Special Agent in Charge Matt Cobo. No one was injured in either incident, but San Francisco District Attorney Brooke Jenkins said the state charges, which include two counts of attempted murder and attempted arson, could carry penalties from 19 years to life in prison. Federal prosecutors added charges of possession of an unregistered firearm and attempted destruction of property by explosives, carrying potential sentences of up to 30 years.

On Monday morning, FBI agents raided Moreno-Gama’s family home in Spring, Texas, a Houston suburb, spending hours gathering evidence. The raid underscored the seriousness with which federal authorities are treating what they describe as a targeted ideological attack rooted in anti-AI extremism.

The episode arrives at a moment of heightened tension in the artificial intelligence debate. OpenAI, once founded with nonprofit intentions to ensure the technology benefits humanity, has transformed into a major commercial player valued in the tens of billions of dollars. Altman has positioned himself as both cheerleader and cautious guardian, testifying before Congress about potential catastrophic risks while simultaneously pushing aggressively for more powerful models and fewer regulatory guardrails. Critics argue this contradiction is precisely what fuels public distrust: a small circle of tech billionaires and venture capitalists racing toward god-like artificial general intelligence while downplaying or even profiting from the very dangers they acknowledge in private.

Prominent voices across the ideological spectrum, from computer scientists to philosophers to former industry insiders, have repeatedly warned that rapid, profit-driven AI development could lead to mass displacement, loss of control, or even human extinction scenarios. Yet those raising such alarms are often dismissed as doomers or cranks by those with the most to gain from the technology’s unchecked expansion. Moreno-Gama’s writings reflect a radicalized version of these concerns, but the underlying fears he expressed are not fringe. They echo statements from figures like the late Stephen Hawking, billionaire Elon Musk, and numerous AI ethics researchers who have called for much slower, safer development.

Jenkins used the occasion to urge cooler heads in the public discourse around AI. “This case should serve as a reminder to turn down the temperature,” she said, warning that heated rhetoric could incite violence. That call is understandable in the immediate aftermath of an arson attack. Yet it also risks papering over legitimate grievances. When powerful corporations controlled by some of the world’s richest men shape the future of human labor, privacy, warfare, and even cognition itself with minimal democratic oversight, it is unsurprising that desperation and rage are growing in some quarters.

The incident also raises questions about the tech industry’s own role in escalating these tensions. OpenAI’s shift from its original mission, its close ties to Microsoft, and Altman’s own history of internal power struggles at the company have painted a picture of an industry that prioritizes speed and market dominance over genuine safety. Internal company documents and leaked memos have revealed how profit motives often override caution. When the people building these systems admit in one breath that AGI could threaten civilization and in the next demand lighter regulation and more compute, public skepticism hardens into outright hostility.

Moreno-Gama is due in court Tuesday. Whether he ultimately represents an isolated fanatic or the bleeding edge of much broader societal anxiety remains to be seen. What is already clear is that the AI gold rush is producing not only trillion-dollar valuations but also deepening fractures, radicalization, and, now, political violence. As Silicon Valley’s leaders continue their march toward ever-more-powerful systems, they might consider that ignoring the growing chorus of warnings carries consequences, both ethical and practical. The fire at Altman’s gate, however indefensible, was not lit in a vacuum.
