Few details in SF stabbing death of Cash App founder Bob Lee

There is little information from police on how technology executive Bob Lee came to be fatally stabbed in downtown San Francisco early Tuesday. Friends and family are mourning Lee, whom they called brilliant, kind and unlike others in the industry. Lee created Cash App and was the chief product officer of MobileCoin at the time of his death. Previously he worked at Google. Lee had recently moved to Miami and grew up in Missouri. Lee used the handle “Crazy Bob” on Twitter, and friends said he was usually up for anything. He leaves behind two children. His death has fueled a debate on public safety in San Francisco.
