Moreno-Gama is accused of traveling from Texas to San Francisco to target Altman and his company. Authorities said he threw a Molotov cocktail at the CEO’s Russian Hill home before threatening to burn down OpenAI’s Mission Bay building early Friday morning.
No one was harmed in either of the incidents. Moreno-Gama’s attorneys said that there was some damage to a gate at Altman’s house.
“Daniel is entitled to due process and fair proceedings. Myself, as well as my co-counsel and the rest of my team, will zealously defend Daniel and seek a just outcome in this case,” Ward told reporters on Tuesday.

Moreno-Gama faces two counts of attempted murder, arson and attempted arson, among other charges, from the San Francisco District Attorney’s office, as well as federal charges for attempted damage and destruction of property by means of explosives and possession of an unregistered firearm, brought by the U.S. Attorney’s office. If found guilty, he could face up to life in prison.
At a press conference announcing the charges against him on Monday, Matt Cobo, the Federal Bureau of Investigation’s acting special agent in charge of San Francisco, said Moreno-Gama’s actions reflected a “dangerous and deliberate plan to bring violence into San Francisco.
“The defendant is alleged to have traveled across state lines with the intent to go target an individual and a major technology company,” Cobo continued. “This was not spontaneous. This was planned, targeted, and extremely serious.”
Moreno-Gama has been in custody since Friday, when he was arrested outside of OpenAI’s San Francisco headquarters. After throwing the Molotov cocktail at Altman’s home, he fled on foot and turned up at the office, where he rammed a chair into the building’s glass doors and threatened to burn it down, killing anybody inside.
SFPD officers said Moreno-Gama was carrying additional incendiary devices, kerosene and a lighter. He also had a document titled “Your Last Warning,” which identified himself as the author, when he was arrested.

The multi-part manifesto allegedly “advocated against AI and for the killing and commission of other crimes against CEOs of AI companies and their investors,” according to the Department of Justice. It also included the names and purported addresses of a number of the sector’s prominent CEOs and investors.
The document ended with an admission to attempting to kill Altman, and a letter addressed to the OpenAI CEO, saying, “If by some miracle you live, then I would take this as a sign from the divine to redeem yourself.”
Cobo said the FBI and SFPD had been in contact with the other AI leaders identified in the manifesto, and did not assess any specific threats toward them.

U.S. Attorney Craig Missakian said the DOJ’s investigation is still developing. He said the incident could evolve to be treated as an act of domestic terrorism if officials determine that Moreno-Gama acted with intent to sway public policy or coerce government or public officials.
Moreno-Gama did not enter a plea on Tuesday, but will remain in custody without bail until his arraignment in May. A court date for the federal charges hasn’t yet been set.
Judge Kenneth Wine also granted a protective order from the district attorney’s office, ordering Moreno-Gama not to have any contact with the people named in the manifesto, or to encourage anyone directly or indirectly to contact them.
“It’s extraordinarily bad,” Wine said of Moreno-Gama’s actions in court.
