Cash App founder Bob Lee was reportedly a regular at underground sex and drug parties with other San Francisco elites — including the sister of the man accused of murdering him, according to a new Wall Street Journal report
Lee’s stabbing on April 4 was originally believed to be the result of random violence in the crime-ridden city.
But friends of the tech tycoon now say it was the result of Lee’s partying with Khazar Momeni, the 37-year-old wife of a prominent plastic surgeon and the sister of Nima Momeni – who has been charged in his death.
Khazar and Lee had been dating in the weeks leading up to his death in early April, his friends told the Wall Street Journaland many feared that he had fallen into a dangerous lifestyle, surrounding himself with the wrong group of people.
Prosecutors have previously said Momeni stabbed Lee multiple times in the heart after vowing to “put him down hard” and grilling him over his relationship with Khazar, with whom the Cash App founder exchanged intimate text messages.
Friends say Cash App founder Bob Lee was a regular at underground sex and drug parties with other San Francisco elites, including the sister of the man accused of killing him

Friends of the slain tech tycoon described how the father of two casually used drugs and regularly partied.
They said Lee, 43, was passionate about developing the Venmo competitor after his career as a Google programmer.
But to unwind, Lee – nicknamed “Crazy Bob” – reportedly takes ketamine and cocaine and travels to raves around the world.
Once, Harper Reed, the CEO of General Calacic Corporation, claimed that he and Lee even took off their pants to attend a party.
Lee, who was separated from his wife, often slept with several women at these parties, including Khazar, sources told the Wall Street Journal.
It was at one of these parties on April 3, when Nima — who sources say was a recluse at these parties, often standing in the corner — confronted Lee.
Prosecutors say Nima asked Lee if he and his sister were “using drugs or anything inappropriate.” Lee assured him that nothing inappropriate had happened.
A few hours later, Lee was found dead with multiple stab wounds.

Lee could be seen on surveillance footage near the apartment building holding his wound

On April 4, Lee was filmed on surveillance cameras as he staggered into a downtown San Francisco apartment building at 2:35 a.m. after being stabbed
Authorities now say that Nima and Lee met again later that night at Khazar’s luxury apartment in the Millennium Tower.
Surveillance footage showed the two getting into Nima’s white BMW and leaving the scene around 2 a.m. on April 4.
He allegedly drove Lee to a remote area several blocks away, where he stabbed the founder of the Cash app several times with a kitchen knife.
Nima then allegedly left Lee to bleed to death in the middle of the street.
Lee was seen stumbling and begging for help that night before collapsing at the Bay Bridge, just 16 minutes from Khazar’s apartment.
Police have said Khazar texted Lee around the time he died.
“Just wanted to make sure you are okay because I know nima came at you really hard,” she wrote in one of these posts.
‘And thank you for being such a classy man who does it with class. Love you selfish jerks.’
A subsequent autopsy found that he had cocaine and ketamine in his system at the time of his death.

Friends of technical director Nima Momeni have previously said his life was ‘unraveling’ in the weeks and months leading up to the alleged stabbing
Nima’s friends have previously shared how his life was unraveling as he dealt with a drug addiction “that left him unable to reason and talk,” fascinated by guns and a history of abuse allegations from an ex-girlfriend.
“This is one of those things where [we’d say]”Nima, you’re cool, we love you, but you don’t make complete sentences,” said an old friend who spoke on condition of anonymity Mission Local.
The friend said he had a very close relationship with sister Khazar to the detriment of other friendships.
“I don’t know who Nima considered his close group, except his sister,” they said. “He would do absolutely anything for her and she would do anything for him.”
His personal life, according to an ex-girlfriend, was equally problematic.
“He wasn’t nice behind closed doors,” she told the outlet. “Called me probably the worst names I’ve ever been given.”
She also said he would be threatening and possessive and would not like to talk to other men. She suspected that he would eventually physically abuse her.
In fact, police records show that he became physically violent in August 2022 by shoving and chastising a woman at his California home.
“I really think he’s scary, and I’ve always found him scary — after I got to know him,” the ex-girlfriend said.
“She believes he is bipolar because one minute he’s fine and the next minute he’s going off for no reason,” said a police report, as cited by never charged with battery.
The outlet claimed he also frequented sex workers, and his behavior with them led to his phone number appearing on a website that shared potentially dangerous clients.
Others have described him as a “boundary pusher,” with one source accusing him of “grabbing me by the hair after I said not to.”
Another review confirmed his cocaine use, calling him “heavily armed,” while others accused him of possessing phantom weapons, the outlet reported.
“He loved his guns. He talked about his guns all the time,” said another of Momeni’s former ex-girlfriends, who also said he kept a lot of knives. “He was a fan of violence.”

Nima’s friends have said he was dealing with a drug addiction ‘that left him unable to reason and talk’ and that he used to insult his girlfriends

Nima Momeni, right, listens to his lawyer Paula Canny, who has said that what his former friends describe does not match her experience with Momeni
But Nima’s lawyer, Paula Canny, has denied these claims.
“I don’t think that’s true,” she said of the allegations that he was a drug addict. “I don’t think he had a drug problem, a serious drug problem. Based on the information I have, I certainly wouldn’t classify him as a drug addict.”
She also denied allegations about his behavior with women and whether he owned firearms.
“I don’t think he’s ever had a gun, I just don’t think that’s true,” Canny said, but added she wasn’t sure.
“Based on what I know, I believe nothing of any evidentiary value was found when the police searched Nima’s apartment the night they arrested him.”
She added, “I don’t know how to react to that either; that’s not my experience with Nima’ when asked about his abusive behavior, noting that ‘everyone has enemies’ who want to destroy his reputation.
The lawyer noted that Nima intends to plead not guilty to the murder charge.
And in a statement to the Wall Street Journal, she said: “My team and I continue to work diligently to investigate all the many aspects of this case and the goings-on of the weeks leading up to the incident.”

In a statement, Khazar’s lawyers appeared to deny her involvement with Lee
In a statement, Khazar’s lawyers also appeared to deny her involvement with Lee.
“There are a lot of rumors about this case, many of which are untrue,” lawyers Mary McNamara and Ed Swanson told The Journal.
‘Mrs. Momeni loves and supports her brother,” they added. “What happened here is a tragedy, and Ms. Momeni is deeply saddened by the suffering of the Lee family as they deal with their terrible loss.”
Lee’s ex-wife, Krista, also denied that her estranged husband was a reveler.
“He was a devoted father,” she said of Lee. “He was more mature than that.”
