The tragic death of Cash App founder Bob Lee was allegedly sparked by an argument with tech start-up owner Nima Momeni over the suspect's sister, Khazar, according to court documents. Prosecutors state that a witness claimed Lee attempted to defuse the situation by reassuring Momeni about his sister's well-being.

The events leading up to Lee's untimely demise have been pieced together using video evidence. The footage shows that on April 4, Lee left his apartment and walked to Khazar's home. A short time later, Nima arrived at the residence, and both men departed in Nima's car, driving to a remote location. It was there that Nima allegedly used a kitchen knife to stab Lee three times, including a fatal wound to the heart. Prosecutors assert that they possess video documentation of the stabbing incident.

Following the argument, Khazar had texted Lee to ensure he was okay, stating, "Nima came wayyyyyy down hard on you." She also expressed her gratitude for Lee's dignified handling of the situation, saying, "Thank you for being such a classy man handling it with class Love you Selfish pricks."

Momeni, who has a record of past arrests, was taken into custody on Thursday in connection with Lee's murder. As part of the ongoing investigation, law enforcement officials searched Khazar's upscale apartment, located near a hotel where Lee had been staying.

The shocking death of Bob Lee has prompted deeper scrutiny into the events leading up to the fatal stabbing. As investigators continue to unravel the circumstances surrounding the tragedy, the connection between the disagreement over Momeni's sister and the eventual violent altercation underscores the severity of the situation.
