A fellow tech entrepreneur has been arrested in the stabbing of CashApp founder Bobby Lee in San Francisco.
Nima Momeni, who runs a tech company called ExpandIt, was apparently in a car with Lee when the two had an argument. It wasn't clear how the two knew each other or what the motive for the alleged stabbing was.
Lee left the car, but the altercation continued, and he was eventually stabbed by Momeni on a quiet street, the allegation said.
Security video shows Lee asking those in a nearby car for help and showing them his injuries, but they did not help and he collapsed on the street. Lee also called 911 for help, but was unconscious by the time help arrived and died later of his injuries.
Momeni faces 26 years in prison if convicted of killing Lee.
San Francisco Mayor London Breed told ABC News people "would be surprised" when the facts of the case come out, and said the killing was not due to danger in the city but was an interpersonal matter.
