Cash App founder's alleged killer to face victim's family in San Francisco court.

Nima Momeni, the man accused of killing Cash App founder Bob Lee, will return to court on May 2 for arraignment. Momeni's attorney requested more time to review evidence in the case. Momeni is expected to plead not guilty. The relationship between Lee and Momeni's sister is believed to be the "link" between the two men. Prosecutors say evidence suggests Lee's killing was premeditated. Lee's death shocked the tech community and raised concerns about violence in downtown San Francisco.
