The 20-year-old Texas man accused of firebombing OpenAI CEO Sam Altman's San Francisco home appeared in court Tuesday. He was denied bail. Prosecutors are pursuing attempted murder charges. And the FBI says this might be domestic terrorism.

Daniel Moreno-Gama did not enter a plea. His public defender, Diamond Ward, argued that this was a "property crime, at best" and accused prosecutors of overcharging her client because of Sam Altman's celebrity status. She told the court that Moreno-Gama has autism and was experiencing an "acute mental health crisis" at the time.

Prosecutors see it very differently. And so does the evidence.

What the Prosecution Says Happened

According to authorities, Moreno-Gama traveled from Spring, Texas, to San Francisco with the specific intent to attack Altman. Early Friday morning, he allegedly hurled a Molotov cocktail at the gate of Altman's $27 million Pacific Heights home, setting it on fire. No one was injured. Officials have not confirmed whether Altman was home at the time.

Less than an hour later, police say he showed up at OpenAI's headquarters three miles away. He allegedly threatened to burn the building down and kill everyone inside, then threw a chair at the glass entrance doors. Surveillance cameras captured the entire incident.

When officers arrested him outside the building, they found a jug of kerosene, a lighter, and a multi-part written manifesto. Sources told Fox News the documents included a hit list of AI executives and investors, complete with names and addresses.

"This was not spontaneous. This was planned, targeted and extremely serious," said FBI San Francisco Acting Special Agent in Charge Matt Cobo.

The Charges Keep Stacking

San Francisco DA Brooke Jenkins has filed two counts of attempted murder, alleging Moreno-Gama targeted both Altman and a security guard at the residence. Additional arson charges bring the potential sentence to anywhere from 19 years to life in prison.

Federal prosecutors have added their own charges: possession of an unregistered firearm and destruction of property using explosives. The FBI raided his Texas home on Monday, spending hours collecting evidence.

U.S. Attorney Craig Missakian said if the evidence shows the attacks were meant to change public policy or coerce officials, "we will treat this as an act of domestic terrorism."

The Bigger Picture

This is not the first violence directed at Altman recently. As we reported, someone shot at his house days earlier. The FBI has been warning other AI executives named in the manifesto. Fortune published an analysis of the online response showing a generational divide: younger commenters expressed sympathy for the attacker's frustrations about AI, even while condemning the violence.

The defense's framing of this as a "property crime" is going to be a hard sell. A cross-country trip, a Molotov cocktail, a kerosene jug, a manifesto with a target list, and threats to kill everyone in a building. That is not a property crime. Whether it is terrorism, a mental health crisis, or both, a judge clearly agreed it warranted no bail.

Moreno-Gama is due back in court May 5. The investigation is ongoing.
