Suspect in Molotov attack at Sam Altman’s California home set to appear in court
The man accused of trying to kill OpenAI CEO Sam Altman by throwing a Molotov cocktail at his San Francisco home is set to make an initial court appearance Tuesday
SAN FRANCISCO (AP) — The man accused of trying to kill OpenAI CEO Sam Altman by throwing a Molotov cocktail at his San Francisco home is set to make an initial court appearance Tuesday.
Daniel Moreno-Gama, of Spring, Texas, traveled to San Francisco last week and hurled the incendiary device at Altman’s home Friday, setting an exterior gate on fire before fleeing on foot, authorities said. Less than an hour later, Moreno-Gama went to OpenAI’s headquarters about 3 miles (5 kilometers) away and threatened to burn down the building, they said.
No one was injured at Altman’s home or the company's offices.
Authorities said Moreno-Gama, 20, expressed hatred of artificial intelligence in his writings, describing it as a danger to humanity and warning of “impending extinction,” according to court filings.
“This was not spontaneous. This was planned, targeted and extremely serious,” FBI San Francisco Acting Special Agent in Charge Matt Cobo said during a news conference Monday.
Moreno-Gama is charged in California state court with two counts of attempted murder and attempted arson, San Francisco District Attorney Brooke Jenkins said. He tried to kill both Altman and a security guard at Altman’s residence, she alleged. Officials have not said whether Altman was home at the time.
Online state court records do not yet show whether Moreno-Gama has an attorney who can speak on his behalf.
Jenkins said the state charges carry penalties ranging from 19 years to life in prison.
On Monday morning, FBI agents went to Moreno-Gama’s home in a Houston suburb where they spent several hours before leaving. He has also been charged by federal prosecutors with possession of an unregistered firearm and damage and destruction of property by means of explosives. Those charges carry respective penalties of up to 10 years and 20 years in prison.

“We will treat this as an act of domestic terrorism, and together with our partners, prosecute him to the fullest extent of the law," U.S. Attorney Craig Missakian said when announcing the federal charges Monday.
The federal court documents do not list an attorney for Moreno-Gama, and he has not yet had his first appearance in federal court.
The document in which Moreno-Gama discussed his opposition to AI also made threats against Altman and executives at other AI companies, officials said.
“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 wrote, according to authorities.
Advocacy groups that have issued grave warnings about AI’s risks to society condemned the violence.
Anthony Aguirre, president and CEO of the Future of Life Institute, said in a written statement Friday that “violence and intimidation of any kind have no place in the conversation about the future of AI.”
Another group, PauseAI, said in a statement that the suspect had no role in the group but joined its forum on the social media platform Discord about two years ago and posted about 34 messages there, none containing explicit calls to violence but one that was flagged as “ambiguous.”
Discord said Monday that it has banned Moreno-Gama for “off-platform behavior.”
