SAN FRANCISCO -- The man accused of throwing a Molotov cocktail at the San Francisco home of OpenAI CEO Sam Altman pleaded not guilty Tuesday to charges of attempted murder and attempted arson.

Daniel Alejandro Morena-Gama, wearing an orange jail uniform, did not speak as his attorney entered the pleas during his arraignment in state court. The 20-year-old also faces federal charges.

Morena-Gama, of Spring, Texas, hurled the flammable bomb at Altman’s home last month, setting an exterior gate alight before fleeing on foot, authorities allege. Less than an hour later, he went to OpenAI’s headquarters about 3 miles (5 kilometers) away and threatened to burn down the building, they say.

After an initial court appearance last month, his lawyer, Diamond Ward, said Morena-Gama was experiencing a mental health crisis and had been excessively charged. Ward, a San Francisco deputy public defender, said it was a “property crime, at best” and that prosecutors were trying to curry favor with Altman.

On Tuesday, Ward requested a mental health evaluation for Morena-Gama. The judge granted the request and scheduled another hearing for later this month.

San Francisco District Attorney Brooke Jenkins said last month that Morena-Gama carried out a “targeted attack on Mr. Altman” and that prosecutors had evidence to substantiate the charges.

Morena-Gama’s parents said in a statement shortly after the attack that he has never harmed anyone and recently began having mental health issues.

Authorities said Morena-Gama, who works part-time at a pizzeria and is attending community college, expressed hatred of artificial intelligence in his writings, describing it as a danger to humanity and warning of “impending extinction,” according to court filings.

Officials haven't said whether Altman was home at the time of the attack.

The state charges carry penalties ranging from 19 years to life in prison.
