Scant details emerge on fatal stabbing of Cash App founder amid safety concerns

San Francisco police have not confirmed the circumstances of Bob Lee's death nor arrested a suspect

Details of how the tech executive Bob Lee came to be fatally stabbed in downtown San Francisco remained scant on Friday, as those who knew the Cash App founder mourn his death and others voiced frustration with public safety.

San Francisco police found Lee, 43, on the sidewalk in front of a condominium building with stab wounds shortly after 2.35am on Tuesday. He was taken to a hospital, where he died. Details about the attack remain thin; surveillance footage released this week reportedly shows Lee stumbling along a sidewalk and seeking help in the aftermath, but police have not confirmed the circumstances of the attack or arrested a suspect.
