Cash App founder Bob Lee’s death: A look at his underground life of sex and drugs

Cash App founder Bob Lee passed away from multiple stab wounds on April 4 this year, turning the spotlight on San Francisco's ‘underground’ party scene replete with drugs and casual relationships. Reports citing his friends also painted the picture of a passionate tech leader who spent a significant part of his leisure time indulging in casual drug use, partying and attending raves around the world.

“Bob Lee’s system is like the Walgreens of recreational drugs,” said the lawyer defending his kitchen knife-wielding alleged assailant. 

The Silicon Valley executive had reportedly spent years participating in ‘The Lifestyle’ and was a frequent attendee in underground sex and drug parties for San Francisco’s elite. Autopsy reports lend credence to the claim, with the city medical examiner’s office stating that Lee had cocaine, ketamine and alcohol in his body when he died.

His social circle, a WSJ report adds, also included his alleged assailant's sister Khazar Momeni - the wife of a prominent plastic surgeon. Reports have linked the two together, with attorneys recently laying heavy emphasis on his ‘drug use’ and consequent ‘bad decisions’.

According to prosecutors, Lee was allegedly confronted by Nima Momeni about the hard partying and his sister’s involvement in the early hours of April 4. Investigators who gained access to Lee's phones following his death discovered a FaceTime call between him and Momeni's sister as well as a text message.

A filing by prosecutors last month said a friend of Lee’s who was having drinks with Lee and Momeni’s younger sister the day before the stabbing told investigators he overheard a FaceTime call in which Momeni confronted Lee over whether his interaction with the sister involved “drugs or anything inappropriate” — which Lee denied.

San Francisco prosecutors, who called the murder "planned and deliberate" also cited surveillance footage to add that Lee and Momeni had left in the latter’s car from the Millennium Tower luxury high-rise apartment building where his sister lived. Momeni drove in the opposite direction of Lee’s hotel where, with both men exiting the car a few blocks away. 

Prosecutors said that Momeni had stabbed Lee three times in the next five minutes - including one wound in the heart that eventually killed him - before speeding away in his BMW and leaving him to slowly die.
