The man accused of trying to kill OpenAI CEO Sam Altman by throwing a Molotov cocktail at his San Francisco home was experiencing a mental health crisis and has been overcharged by prosecutors, his public defender said Tuesday.

Daniel Moreno-Gama made his first court appearance on state charges with disheveled hair and wearing an orange jail uniform. The 20-year-old, whose attorney said is autistic, kept his gaze down during the brief hearing and softly answered “yes” when asked by a judge whether he agreed to continue his arraignment. San Francisco Judge Kenneth Wine ordered him held without bail and set his arraignment for May 5.
