Now, the San Francisco Police Department has arrested a suspect, local news publication [*Mission Local* reports]() — a man Lee not only knew personally, but may have been in a car with just hours before his murder. In other words, Lee's death may not have been the victim of a random stabbing — the tech crowd was [quick to blame the homeless]() — but the result of a grievance between two acquaintances. ## Lethal Grievance The alleged killer, Nima Momeni, owns a Bay area computer services company called Expand IT. According to police reports, he was driving Lee through a deserted part of San Francisco in the early morning hours of April 4, just hours before the stabbing occurred. The SFPD alleges that a fight broke out between the two men while they were driving and may have continued after Lee left the vehicle, which was registered to Momeni. A knife was later recovered not far from the scene, which Momeni may have dropped after fleeing. The police department's scenario — to reiterate, it's just a theory at this point — could help explain why Lee was wandering through the streets of an empty part of downtown San Francisco at 2:30 am on April 4. Lee's death drew a huge amount of social media coverage, giving San Francisco "a feeling of a city coming undone," as *Mission Local* points out. But a grievance between two estranged tech execs, for obvious reasons, undermines those narratives. **More on the incident:** *[The Cofounder of Cash App Just Got Murdered]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
