Tech executive Bob Lee dies after stabbing; toxicology report reveals drug use

Bob Lee, the founder of Cash App, was fatally stabbed three times in San Francisco last month.
Nima Momeni has been charged with Lee's murder following an argument over Momeni's sister.
Lee had cocaine, ketamine, alcohol and several other drugs in his system at the time of the attack according to autopsy and toxicology reports.
Doctors worked for over four hours trying to save Lee before he was pronounced dead on the operating table.
Momeni's arraignment has been delayed three times as new details surrounding Lee's death and their dispute have emerged.
