I cut my teeth in journalism when I began looking into what I saw as abuses of power in my local government. From then on, I was hooked on the dopamine rush of uncovering information.

SAN FRANCISCO — A suspect was arrested early Friday after an apparent arson attack targeted OpenAI CEO Sam Altman’s home and was followed by threats to burn down the company’s headquarters.
FOX 35 Orlando reported that the first incident unfolded just before 4 a.m. near Jones and Leavenworth streets, where someone threw a Molotov cocktail at an exterior gate of Altman’s San Francisco residence.
San Francisco police and firefighters responded to the home, where the fire had already self-extinguished by the time officers arrived, according to police. Investigators recovered evidence of an incendiary device at the scene, and no injuries were reported.
Police have not said whether Altman was inside the home when the device was thrown. According to SFPD, the suspect fled the area on foot after the attack.
Less than an hour later, at about 5 a.m., officers were called to a business in the 1400 block of 3rd Street, the site of OpenAI’s Mission Bay headquarters, after reports that a man was threatening to burn the building down, according to police.
SFPD identified the suspect as Daniel Alejandro Moreno-Gama, 20, and said he was the same person connected to the earlier arson attack at Altman’s home. Officers took him into custody at the scene, according to police.
OpenAI later issued a statement thanking authorities for their response. “We deeply appreciate how quickly SFPD responded and the support from the city in helping keep our employees safe,” the company said, according to OpenAI.
Altman purchased the San Francisco home in 2020, according to prior reporting cited in the case coverage. Authorities have not released additional details about a possible motive.
Presumption of Innocence: A presumption of innocence means that any defendant in a criminal trial is presumed to be innocent until they have been proven guilty beyond a reasonable doubt in a court of law. The defendant in this case is only accused of the charges set forth in the criminal complaint. They are innocent until proven guilty.
