Who is Nima Momeni? Suspect in Bob Lee stabbing in San Francisco

California police have arrested a self-described tech entrepreneur in connection with the stabbing death of Silicon Valley mogul Bob Lee, the founder of Cash App and an executive at Square and MobileCoin who was killed last week.

San Francisco jail records show that Nima Momeni, 38, was booked around 9:20 a.m. Thursday on a charge of first-degree murder. District Attorney Brooke Jenkins said she had also filed a special circumstance allegation that the crime had been committed with a knife.

A LinkedIn profile in Momeni's name identifies the IT professional as the owner of an outsourcing firm called Expand-IT.
