Prosecutors plan to ask a judge Tuesday to ask a San Francisco judge to hold the man accused of trying to murder OpenAI CEO Sam Altman held without bail because of the “public safety risk he poses,” they said.
Daniel Moreno-Gama, a 20-year-old Texas resident, allegedly threw a lit Molotov cocktail at Altman’s home and threatened to burn down OpenAI’s headquarters last week because of his hatred for artificial intelligence technology.
Moreno-Gama, who is scheduled to be arraigned in San Francisco Superior Court at 4:30 p.m., is charged with attempted murder, attempted arson and exploding or igniting a destructive device with intent to murder.
He is separately charged by federal prosecutors with attempted damage and destruction of property by means of explosives and possession of an unregistered firearm.
San Francisco Police Department officers arrested Moreno-Gama on Friday and recovered a document in his possession that detailed his intentions, according to a complaint filed in San Francisco federal court on Monday.
In the document, Moreno-Gama expressed his aim to kill Altman and warned of humanity’s “impending extinction” from AI. He also listed the names and addresses of several additional AI executives, board members and investors, the complaint said.
Altman addressed the attack on his home in a blog post on Friday, and said it has been an “extremely intense, chaotic, and high-pressure few years.”
He shared a photo of his family and called for de-escalation of “the rhetoric and tactics” within the AI industry.
“We deeply appreciate how quickly SFPD responded and the support from the city in helping keep our employees safe,” OpenAI said in its statement on Friday. “The individual is in custody, and we’re assisting law enforcement with their investigation.”
