Mystery Surrounds Stabbing of Tech Leader Bob Lee

You know Bob Lee, right? He was the big boss at MobileCoin, a cryptocurrency company, and one of the founders of Cash App. Sadly, he died last year. It was a shock to the tech world. Now, a guy named Nima Momeni is on trial for stabbing him. Prosecutors say Momeni had a dispute with Bob over his sister, Khazar, and planned the attack. They think he took a knife, drove Bob to a quiet street, and stabbed him. Nima's lawyer has a different story. They say Bob was high on drugs and attacked Nima in self-defense.The night of the killing, Bob went to see Khazar, who lives in a fancy downtown building. A friend said they had been drinking together before. Later, Bob and Nima left the building and drove off. Bob was found on a street nearby, injured. Police found a knife with both Nima and Bob's DNA on it. But the defense wants fingerprints tested too. Nima faces a long prison time if found guilty. The trial could take until December.
