Daniel Moreno-Gama is now facing federal charges after allegedly traveling from Texas to California with the intent to kill OpenAI CEO Sam Altman. On April 10th, he was arrested after throwing a Molotov cocktail at OpenAI CEO Sam Altman’s home and attempting to break into OpenAI’s headquarters. According to prosecutors, at the HQ, “Moreno-Gama attempted to break the glass doors of the building with a chair and stated that he had come to burn down the location and kill anyone inside.”
His charges include “attempted damage and destruction of property by means of explosives and possession of an unregistered firearm,” according to the Department of Justice, and carry maximum sentences of 20 years and 10 years, respectively.
In addition to being in possession of “incendiary devices, a jug of kerosene,” and a lighter, San Francisco Police Department officers found that Moreno-Gama had a document: titled “Your Last Warning” that “advocated against AI and for the killing and commission of other crimes against CEOs of AI companies and their investors.”
From the complaint:
As noted above, SFPD officers recovered a document from MORENO-GAMA. MORENO-GAMA appears to have sent a similar version of the document via email to individuals at his former college in Texas on April 10, 2026. The document was a three-part series that MORENO-GAMA apparently authored, which identified views opposed to Artificial Intelligence (AI) and the executives of various AI companies, including Victim-1.
The first part of the document was titled “Your Last Warning” followed by “Daniel Moreno-Gama.” In this part of the document, MORENO-GAMA stated he “killed /attempted to kill” Victim-1. MORENO-GAMA also wrote, “Also 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.” MORENO-GAMA further listed the names and addresses of apparent board members and chief executive officers of AI companies and investors.
The second part of the document was titled “Some more words on the matter of our impending extinction.” In this part, MORENO-GAMA discussed the purported risk AI poses to humanity.
The third part of the document was a letter to Victim-1 addressed as: “To [Victim-1’s name] if you make it” in which MORENO-GAMA states “If by some miracle you live, then I would take this as a sign from the divine to redeem yourself…”
