Cash App Founder's Underground Life: Sex, Drugs, and Affair with Alleged Killer's Sister

Cash App founder Bob Lee allegedly frequented San Francisco's underground party scene, involving drugs and sex, and was sleeping with Khazar Momeni, the sister of his alleged killer, Nima Momeni. Lee was confronted by Nima about his sister's involvement in an argument, which led to Lee's stabbing and death. Lee's friends suggested that his indulgent lifestyle among the upper echelon of Bay Area society, where cocaine and swingers were common, may have contributed to his death. Nima was arrested and charged with murder.
