Arrest made in Bob Lee killing; suspect is tech entrepreneur Nima Momeni

San Francisco police made an arrest Thursday morning in connection with the stabbing death of Cash App founder Bob Lee, a crime that convulsed the city’s tech community and inflamed fears of surging violence downtown.

District Attorney Brooke Jenkins charged 38-year-old Emeryville resident Nima Momeni with murder for allegedly stabbing Lee twice in the chest at 2:30 a.m. on April 4, leaving a trail of blood on the sidewalk in San Francisco’s wealthy Rincon Hill neighborhood. Lee, 43, was a colorful, outsize figure, known for his leadership role at Square and for working on the team that launched Google’s Android operating system, but more often remembered as the last guy to leave any party.

Officers booked Momeni into San Francisco County Jail at 9:19 a.m. He was scheduled to appear for his first court hearing on Friday.

The victim and the accused killer knew each other, Police Chief Bill Scott told reporters who gathered Thursday afternoon at the department’s headquarters in China Basin. Scott said officers had served two search warrants in San Francisco in addition to the arrest and search warrant in Emeryville, but he declined to offer more detail.
