IT consultant pleads not guilty in fatal stabbing of Cash App founder, claims self-defense.

IT consultant Nima Momeni pleaded not guilty to fatally stabbing Cash App founder Bob Lee in San Francisco after an argument over the suspect's sister. Momeni faces 26 years to life behind bars. His lawyer claims the stabbing was a "combination of an accident and self-defense," while prosecutors insist that Momeni was a "murderer" who stabbed Lee intentionally. Lee was best known for creating Cash App and was an investor in SpaceX and other tech companies. An autopsy report revealed he had ingested alcohol, cocaine, and ketamine before he was killed, though the substances were not linked to the cause of death.
