Cash App founder's murder suspect's motive revealed.
Nima Momeni, a tech consultant and entrepreneur, has been charged with the murder of Cash App founder Bob Lee in San Francisco. Prosecutors allege that Momeni was upset over Lee's relationship with his sister and stabbed him three times with a kitchen knife before leaving him to "die slowly" on the street. Lee and Momeni's sister were drinking with a friend before Lee left with Momeni to go to her apartment. Surveillance footage shows Momeni and Lee leaving the apartment together before Lee was attacked. Momeni has been charged with murder and faces 26 years to life in prison if convicted.
