Fatally stabbed Cash App founder allegedly led underground lifestyle of sex and drugs, partied with accused killer's sister and slept with his ex

Cash App founder Bob Lee, who was stabbed to death in San Francisco, allegedly took part in an underground lifestyle filled with sex, drugs, and raves, according to reports from Fox News and the Wall Street Journal.

Lee was reportedly a member of a wealthy group of socialites known as "The Lifestyle," and so was the sister of his suspected killer. Reports allege that this could be the connection that led to Lee's death.

Lee's autopsy reportedly revealed ketamine and cocaine in his system, according to the San Francisco Office of the Chief Medical Examiner. Along with taking ecstasy, Lee would go to all-night raves all across the world, according to his friends.

According to one of Lee's friends named Harper Reed, the chief executive of General Galactic Corporation, a financial technology start-up, he and Lee once went pants-less into a club in order to capitalize on a promotion that would save them $15 on the venue's cover charge.

Nima Momeni, Lee's suspected killer, allegedly confronted the tech mogul about partying with his sister, 37-year-old Khazar Momeni, hours before the stabbing. A witness told police that the alleged killer argued with Lee for allegedly using drugs with his sister.

Additionally, Lee had also allegedly slept with an ex-girlfriend of the murder suspect. Lawyers for the sister have denied rumors about the case.

Court documents stated that the sister indeed met with Lee hours before his death, which investigators confirmed using surveillance video from her apartment building.

The documents also said video showed Lee and Momeni leaving the sister's apartment before getting in a car and driving to a location where Lee was found with three stab wounds. A bloody, discarded four-inch kitchen knife was found at the scene.

The sister had even texted Lee saying he "handled himself with class" after her brother allegedly "came wayyyyyy down hard" on him.

Lawyers for Momeni did not respond to request for comment.

Krista Lee, the victim's separated wife, disputed that Lee was a "party boy" and claimed she never heard the term "The Lifestyle."

“He was a dedicated father. He was more mature than that,” she said. Lee's wife also said she suspected any ketamine use of his was actually microdosing to treat his depression.
