Suspect in Bob Lee murder case confronts victim's family before arraignment.

Court documents reveal that Nima Momeni, a Bay Area-based tech executive, confronted Bob Lee, the Cash App founder, about Lee's relationship with Momeni's younger sister just hours before Lee was brutally stabbed to death in San Francisco. Momeni has been charged with murder and is currently in jail without bail. Prosecutors filed court documents containing grisly details about what led up to the killing to ensure Momeni remains behind bars. Lee, a divorced father of two who made millions working in the Bay Area tech industry, was found bleeding and stumbling while trying to find help after being stabbed three times in the chest.
