Bob Lee, the founder of Cash App, was stabbed to death in San Francisco on April 4th. An autopsy report revealed that he had alcohol, cocaine, ketamine, and allergy medication in his system at the time of his death, although no link was made between these substances and his cause of death. Lee's family has set up a memorial fund in his honor and asked for privacy during this difficult time, while the San Francisco Police Department continues to investigate the case.
