Bob Lee murder suspect pleads not guilty, claims self-defense.

Nima Momeni, the man accused of fatally stabbing Cash App founder Bob Lee, has pleaded not guilty to murder. Prosecutors allege the stabbing was the result of a dispute between the two men that centered on Lee’s relationship with Momeni’s sister, Khazar Elyassnia. Momeni's defense attorney argued that the narrative put out by San Francisco police is based on hard-to-see video evidence. Momeni is not a US citizen and is at risk of being deported to his home country of Iran.
