Police arrest suspect in killing of Cash App founder Bob Lee (updated)

The accused man reportedly ran his own tech company.


Police have arrested a suspect in the killing of Cash App founder and former Square executive Bob Lee. Board of Supervisors President Aaron Peskin has confirmed to The San Francisco Chronicle that someone is in custody in connection with the April 4th stabbing of the 43-year-old in San Francisco.

This might not have been a mugging or random murder. Mission Local sources claim the suspect is Nima Momeni, the Emeryville-based owner of outsourcing firm Expand IT. Lee reportedly knew Momeni and was a passenger in a car belonging to the suspect, the insiders say. A confrontation supposedly erupted in the car, and may have continued after Lee stepped out.

We've asked the San Francisco Police Department for comment. Lee was most recently the chief product officer of crypto startup MobileCoin. Before his time with Square, he helped create Android's early core library. He was also an investor in tech startups and helped develop the World Health Organization's mobile app during the height of the COVID-19 pandemic.

If accurate, the report would explain why Lee was killed in a section of San Francisco that rarely sees pedestrian traffic in the early morning. It would also make the death a historical rarity. While there are certainly personal feuds in tech, they seldom escalate to violence.

Update 4/13 3:43PM ET: The SFPD has confirmed in a press conference that it arrested Momeni for Lee's murder, and that the two knew each other. It's not sharing more details as there's an ongoing investigation.
