Khazar Momeni, the sister of the man accused of fatally stabbing tech executive and Cash App founder Bob Lee last year, said her brother didn't kill Lee shortly after she took the stand Thursday afternoon.

Khazar Momeni, a year and a half after her brother allegedly killed Cash App founder Bob Lee, broke her silence today.

Opening statements were set to begin Monday in the trial of Nima Momeni, the man accused of fatally stabbing San Francisco tech executive Bob Lee.

The sister of Nima Momeni, the man on trial for allegedly killing Cash App founder Bob Lee, was called to testify Thursday.

As the trial of accused Bob Lee killer Nima Momeni heads into its second day, Momeni’s sister, Khazar Momeni, is expected to take the stand on Tuesday. Lee, who was 43 when he was killed, was at Khazar’s apartment and left with her brother Nima in the early hours of April

A friend of slain tech executive Bob Lee testified Wednesday that the victim received a "bizarre" phone call from Nima Momeni the night before the killing in which Momeni accused Lee of acting inappropriately with his sister.

The most anticipated witness in the murder trial of Cash App founder Bob Lee, Khazar Momeni — who is the defendant’s sister — testified Thursday that her memories surrounding the days before and following Lee’s stabbing were hazy from frequent abuse of nitrous oxide and “self-destructive” behavior after she learned her friend had died.
