Key ‘witness’ in Cash App founder Bob Lee’s murder who spent final hours with tech CEO ‘refuses to cooperate’ with cops

THE sister of a man who stands accused of stabbing Cash App founder Bob Lee to death refuses to cooperate with police, the San Francisco District Attorney said.

Khazar Elyassnia is believed to be a key witness in the case after she was allegedly with the tech CEO moments before he was found bleeding out on a San Francisco street.

Elyassnia, the wife of a wealthy Bay Area surgeon, is the sister of Nima Momeni, 38, who is being held in jail for allegedly murdering Lee after the two got in a spat over her, the San Francisco Chronicle reports.

On April 3, Momeni quizzed Lee on his sister’s alleged drug use and accused him of encouraging bad behavior while they were at an underground party event frequented by the nouveau riche of San Francisco, a witness told the Wall Street Journal.

Sources close to the matter told the outlet that Lee and Elyassnia weren’t in a relationship but were casually having sex when he was killed.

A witness said that Lee attempted to calm the situation and told Momeni that he would never try to harm his sister.

Prosecutors believed that hours later, Momeni allegedly stabbed Lee with a kitchen knife and left him to bleed to death in the street.

An autopsy found that he had cocaine and ketamine in his system when he was found.

The bombshell report by WSJ revealed more details about the wild life of Lee who was said to run in a crowd of young, successful, party animals.

While many sources remembered him as a kind and giving friend, one friend and former coworker Dana Wagner, who worked with Lee at the tech-company Square, said the Cash App founder was on a dark path.

“He was also hanging out with people who weren’t great people, and that was part of what happened in the end,” Wagner told the Journal.

“There are a lot of swingers, cheaters, and liars in that crowd.”

Authorities say that they have made multiple attempts to contact Elyssnia, but she refuses to sit for an interview.

Meanwhile, Momeni’s attorney, Paula Canny, claimed that police didn’t contact her until after her brother was arrested, and that she only wished to have a lawyer present when she speaks with cops.

Lee was said to have been embroiled in an underground party scene called The Lifestyle, where socialites participated in sex and drug parties, according to the Journal.

The tech whiz was separated from his wife Krista Lee, but the two maintained a good relationship as he would oftentimes travel to visit their two teen sons, Lee said.

His estranged wife appeared during Momeni’s court hearing on Thursday and has adamantly supported Lee in the press.

The night of the killing, a surveillance camera later captured Lee and Momeni getting into the suspect’s white BMW in front of the sister’s apartment at around 2am on April 4.

After they made it to downtown San Francisco, the two men were seen standing together on a sidewalk for several minutes.

Then, surveillance footage appears to show Momeni stabbing Lee, tossing the knife, and speeding away in his car.

When police arrived at 2.30am, they found Lee bleeding uncontrollably from three stab wounds.

Lee’s injuries seemed to show a “clear intent to kill,” court docs say.

“One of the stab wounds, showing a direct and clear intent to kill, penetrated Victim’s heart.

“Immediately after stabbing Victim, Defendant threw the kitchen knife, fled the scene in his white BMW at a high rate of speed, and left Victim to slowly die,” the documents continued.

Authorities were able to unlock Lee’s phone, they discovered a text message sent by Elyassnia.

Elyassnia seemed concerned for Lee, telling him: “Just want to make sure you are ok Cause ‘I know [Nima] came wayyyyy [sic] down hard on you.

“And thank you for being such a classy manhandling it with class Love You selfish pricks.”

Momeni appeared in court on Thursday where he pleaded not guilty to the murder.

Elyassnia wrote a letter that was read to the court where she said she and her brother were close but he was never controlling.

“We are close friends, as close as a brother and sister can be,” the letter read.
