Socialite sister of Cash App founder Bob Lee’s accused killer takes stand in San Fran murder trial

The murder trial of Cash App founder Bob Lee continued in San Francisco Thursday as the glamorous, hard-partying sister of his accused killer made her long-anticipated appearance on the witness stand.

Khazar Elyassnia was sworn in just after 2:30 p.m., and the socialite was decked out in a $5,500 powder-blue patterned Valentino Garavani dress, oversized white sunglasses with orange lenses and toted a $1,000 Valentino clutch, exclusive photos obtained by The Post show.

Elyassnia, 38, who allegedly was involved in an affair with the deceased millionaire, has been a central figure in the explosive trial in which her brother, Nima Momeni, 40, is facing accusations he stabbed Lee to death defending his sister’s honor.

Lee and Elyassnia, who is married to a prominent plastic surgeon, allegedly shared a penchant for a glitzy, underground San Francisco party scene known as “The Lifestyle,” infamous for free-flowing drugs and casual sex.

On the night of the killing, Elyassnia and Lee had attended one of the raucous gatherings, and Momeni had come to believe Lee had drugged and raped his sister, prosecutors alleged during opening statements Monday.

This led Momeni to seek out vengeance on his sister’s behalf, with prosecutors alleging he viciously stabbed the Silicon Valley mogul in the early morning hours of April 4, 2023.

That night, 43-year-old Lee was found bleeding out and begging for help in the heart of San Francisco at 2:30 a.m., soon after he was seen leaving Elyassnia’s tony Millennium Tower home alongside Momeni.

Momeni has pleaded not guilty, his lawyers saying he killed Lee in self-defense, alleging the tech founder was high on drugs and tried to slash Momeni.
