SPRING, Texas – The FBI has conducted a raid on the residence of a 20-year-old suspect in Texas, who is alleged to have hurled a Molotov cocktail at the home of OpenAI CEO Sam Altman in San Francisco. This information has been confirmed by Fox News.
Fox News was present as federal agents executed a search warrant and collected evidence at the suspect’s home in Spring, Texas, during the early hours of Monday.
The individual in question, Daniel Moreno-Gama, is accused of traveling from Texas to San Francisco with the intent to harm the OpenAI CEO.
Insiders connected to the investigation disclosed to Fox News that Moreno-Gama’s motivations stemmed from his opposition to artificial intelligence. Upon his arrest in San Francisco, he was found in possession of a manifesto. This document, reportedly a “three-part series,” contained a list of other AI executives and investors, complete with their names and addresses.
Surveillance footage has captured an image of Moreno-Gama, who has been apprehended in connection with the Molotov cocktail incident at Sam Altman’s San Francisco residence.
San Francisco District Attorney Brooke Jenkins has cautioned against the rising fervor surrounding artificial intelligence, emphasizing that this case serves as a critical reminder to temper public discourse and refrain from engaging in rhetoric that could incite violence.
According to San Francisco police, Moreno-Gama threw a Molotov cocktail at Altman’s house early Friday morning, setting the front gate on fire. No one was hurt.
Police say he then went to OpenAI headquarters, where he was captured on surveillance video throwing a chair at the glass doors. Security told police he said he planned to burn the building down and kill anyone inside.

Moreno-Gama was arrested outside the building by San Francisco police and has remained in custody. Investigators say he was carrying a jug of kerosene and a lighter.
The Justice Department filed federal charges Monday afternoon for attempted damage and destruction of property by means of explosives and possession of an unregistered firearm.
Moreno-Gama is already charged with multiple state felonies, including attempted murder, in connection to the incident at Altman’s home.
On Monday, San Francisco prosecutors outlined additional details, charging Moreno-Gama with attempted murder of Altman and a security guard, along with multiple arson and explosives-related offenses. Jenkins said the attack was “willful, deliberate and premeditated,” adding that authorities view it as a direct attempt on Altman’s life.
Prosecutors also filed charges tied to a second incident at OpenAI headquarters, including attempted criminal threats and attempted arson.
Federal authorities said the suspect’s actions were not spontaneous. Acting FBI Special Agent in Charge Matt Cobo said Moreno-Gama traveled across state lines in what investigators believe was a “planned” and targeted attack.

Altman responded to the attack on his blog with a picture of his family saying, “I love them more than anything,” and, “normally we try to be pretty private, but in this case I am sharing a photo in the hopes that it might dissuade the next person from throwing a Molotov cocktail at our house, no matter what they think about me.”
Over the weekend, two more people were arrested in a separate incident, after reports of gunfire near Altman’s home, according to San Francisco Police.

“The SFPD takes crimes involving guns extremely seriously, and anyone committing acts like these will be arrested and prosecuted to the fullest extent of the law,” said Chief Derrick Lew. “I want to thank our officers whose swift actions identified these suspects, took them into custody, and got dangerous weapons off our streets.”
An OpenAI spokesperson told Fox News Digital Monday morning that the incident was unrelated and had no connection to Altman, adding that there was no indication that Altman’s home was being targeted.
