Investigators obtained records showing the woman contacted the Union Square Plaza Hotel on April 8 to extend Moreno-Gama's stay, two days before he allegedly threw a Molotov cocktail at Altman's residence and was later arrested at OpenAI's headquarters. The search for the woman comes as Moreno-Gama faces separate state and federal charges, including attempted murder and arson, with his attorneys seeking mental-health diversion.", "body_md": "A search is underway for an unidentified young woman who called to request a late checkout for the suspect in the OpenAI firebomb attack in April, and the SFPD thinks she may be a co-conspirator.\n\nInvestigators with the San Francisco Police Department are looking into whether Daniel Moreno-Gama, the Texas man accused of firebombing OpenAI CEO Sam Altman's Russian Hill home, may have had help, [as the Chronicle reports](https://www.sfchronicle.com/crime/article/altman-openai-home-firebomb-investigation-woman-22299437.php).\n\nBased on records recently obtained by the outlet, police are reportedly trying to identify a young woman who called the Union Square Plaza Hotel on April 8 to request a late checkout for Moreno-Gama, who had checked into the hotel two days prior — he checked back in April 9 before the April 10 attack. This led police to consider the possibility that Moreno-Gama was coordinating with another person.\n\nAs SFist reported previously, Moreno-Gama, who [pleaded not guilty](https://sfist.com/2026/05/05/20-year-old-texas-man-accused-of/) in the attack, was captured on surveillance video [throwing a Molotov cocktail](https://sfist.com/2026/04/10/molotov-cocktail-thrown-at-sam-altmans-house-suspect-arrested-outside-openai-headquarters/) at the exterior gate of Altman’s home. Shortly after, Moreno-Gama was arrested after attempting to break into OpenAI's Mission Bay headquarters while holding a jug of kerosene.\n\nAccording to the Chronicle, the records also reportedly show that Moreno-Gama spent the night of April 8 in Redding, at a La Quinta Inn, before checking back into the Union Square Plaza Hotel the next day. Authorities have not said why Moreno-Gama made the trip to Redding or what he did while there.\n\nTwo days after the firebombing, police were reportedly called back to the Union Square Plaza Hotel after a housekeeper discovered a firearm in a room registered to Moreno-Gama.\n\nMoreno-Gama is due in court next month and remains in custody while facing separate state and federal prosecutions, as previously reported. His attorneys are seeking mental-health diversion in the state case, where he has pleaded not guilty to attempted murder and attempted arson charges, while federal explosives and firearms charges are also pending.\n\n**Previously:** [20-Year-Old Texas Man Accused of Firebombing Sam Altman's House Enters Not Guilty Plea](https://sfist.com/2026/05/05/20-year-old-texas-man-accused-of/)", "url": "https://wpnews.pro/news/police-search-for-potential-co-conspirator-in-openai-firebomb-attack", "canonical_source": "https://sfist.com/2026/06/11/police-search-for-potential-co-conspirator-in-openai-firebomb-attack/", "published_at": "2026-06-11 18:37:30+00:00", "updated_at": "2026-06-11 19:37:13.333654+00:00", "lang": "en", "topics": ["ai-safety", "ai-policy"], "entities": ["OpenAI", "Sam Altman", "San Francisco Police Department", "Daniel Moreno-Gama", "Union Square Plaza Hotel"], "alternates": {"html": "https://wpnews.pro/news/police-search-for-potential-co-conspirator-in-openai-firebomb-attack", "markdown": "https://wpnews.pro/news/police-search-for-potential-co-conspirator-in-openai-firebomb-attack.md", "text": "https://wpnews.pro/news/police-search-for-potential-co-conspirator-in-openai-firebomb-attack.txt", "jsonld": "https://wpnews.pro/news/police-search-for-potential-co-conspirator-in-openai-firebomb-attack.jsonld"}}
