FBI agents executed a search warrant Monday morning at a home in Spring, Texas, belonging to the 20-year-old man accused of hurling a Molotov cocktail at OpenAI CEO Sam Altman's San Francisco house and then heading to company headquarters armed with kerosene and a lighter.
Daniel Moreno-Gama now faces federal charges of attempted damage and destruction of property by means of explosives and possession of an unregistered firearm, Fox News reported, citing a federal criminal complaint. He already faced multiple state felonies in California, including attempted murder, tied to the same incident at Altman's home.
Sources close to the investigation told Fox News that Moreno-Gama was driven by anti-AI views and had authored a three-part manifesto. The Justice Department was expected to file the federal charges Monday afternoon. Fox News reported it was exclusively on the ground during the Texas search.
San Francisco police said Moreno-Gama threw a Molotov cocktail at Altman's house early Friday morning. The device set the front gate on fire. No one was hurt.
After the house attack, police said Moreno-Gama traveled to OpenAI's San Francisco headquarters. Surveillance video captured him throwing a chair at the building's glass doors. Officers arrested him outside the building. Investigators said he was carrying a jug of kerosene and a lighter at the time of his arrest on April 10, 2026.
He has remained in custody since.
The FBI's decision to raid a suspect's home hundreds of miles away, in a Houston-area suburb, signals the federal government is treating this as far more than a local vandalism case. That posture is appropriate. A man allegedly crossed state lines to firebomb the residence of one of the most prominent technology executives in the country, then reportedly moved on to the company's offices while carrying accelerants.
This is the kind of FBI-led enforcement action that shows federal resources applied where they belong, protecting citizens from politically motivated violence.
The Molotov cocktail attack was not the only alarming incident near Altman's residence. Over the weekend, San Francisco police arrested two more people in a separate incident after reports of gunfire near his home. Chief Derrick Lew addressed the broader pattern directly.
Lew stated:
"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."
He added:
"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 that the separate weekend gunfire incident was unrelated and had no connection to Altman, adding there was no indication Altman's home was being targeted in that case. The distinction matters legally. But for anyone living on that block, two violent incidents in a matter of days is not a reassuring pattern.
Federal agents raiding private homes always draws public attention. In this case, the search in Spring, Texas, appears squarely tied to building the federal prosecution, gathering evidence from the place Moreno-Gama reportedly left before allegedly traveling to California to carry out his attack.
Sam Altman responded to the attack on his blog by posting a picture of his family. His message was brief and personal.
Altman wrote:
"I love them more than anything. 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."
That line, "no matter what they think about me", captures something worth sitting with. Altman is a lightning rod for criticism in certain corners of the political and cultural landscape. Debates about artificial intelligence, its economic disruption, and its ethical boundaries are legitimate. None of that legitimizes arson or attempted murder.
The charges laid out in the federal criminal complaint, attempted destruction of property by means of explosives and possession of an unregistered firearm, carry serious weight. Combined with the state attempted-murder charge, Moreno-Gama faces the prospect of decades behind bars if convicted.
Sources close to the investigation told Fox News that Moreno-Gama was motivated by anti-AI views. He reportedly wrote a three-part manifesto. The details of that document have not been publicly released, and it remains unclear what specific grievances it contained.
But the alleged motive raises a question that law enforcement and policymakers will need to grapple with. Hostility toward artificial intelligence and the companies building it has been growing in certain online communities. When that hostility crosses from heated rhetoric into firebombing a family's home, it becomes domestic terrorism by any reasonable definition.
The federal charges suggest prosecutors see it that way, too. Attempted destruction of property by means of explosives is not a charge you bring for a bar fight. It signals intent to treat the act as what it appears to be: a premeditated, ideologically driven attack.
Heavy law-enforcement operations at private residences have become a recurring feature of federal investigations in recent months. Whether it's FBI raids on Georgia election offices or tactical searches tied to gang activity and fraud, the bureau has shown a willingness to move aggressively when the evidence warrants it.
In this case, the evidence appears to include surveillance video, physical evidence recovered at the arrest scene, and whatever agents found inside the Spring, Texas, home on Monday morning.
Several details remain unresolved. The court and district handling the federal complaint have not been publicly identified. The exact contents of Moreno-Gama's reported manifesto are unknown. The identities and charges, if any, of the two people arrested in the separate weekend gunfire incident near Altman's home have not been disclosed.
It is also unclear what, specifically, FBI agents recovered during Monday's search in Texas. Fox News reported being on the ground during the raid, but the bureau has not publicly detailed the items seized.
Aggressive law-enforcement searches of private homes always warrant scrutiny. Citizens have rights, and warrants must meet constitutional standards. But when a 20-year-old allegedly travels from Texas to California carrying incendiary devices and targets a private residence with a Molotov cocktail, the federal response should be swift, thorough, and unsparing.
By all appearances, that is what happened here.
Ideological grievances, left, right, or otherwise, do not entitle anyone to firebomb a family's home. The charges against Daniel Moreno-Gama are serious. The federal investigation appears to be moving at the pace the facts demand. San Francisco police made the arrest. The FBI followed up across state lines. The Justice Department is bringing federal charges.
That is how the system is supposed to work. When someone allegedly acts on extremist views by attacking a private citizen's home with an explosive device, every level of law enforcement should respond as though it matters, because it does.
Disagree with AI all you want. Write your manifesto. Protest on the sidewalk. But the moment you light a Molotov cocktail and throw it at someone's front gate, you've forfeited the right to call yourself anything but a criminal.
