The San Francisco Police Department has made an arrest in the killing of Bob Lee, the popular cash app founder. The suspect, Nima Momeni, is a 38-year-old tech entrepreneur from Emeryville, California. The police say that they already knew each other before the incident, and that Lee was killed in a car by Momeni on April 4 from multiple knife wounds. The arrest comes after a heavily publicized push by the community to bring Lee's killer to justice.

Lee's murder was initially considered a part of a spate of violent crime that has shaken San Francisco's tech-obsessed community, leading to criticism of the authorities. However, the police have maintained that the crime was personal rather than a robbery or a random attack. Despite the arrest, investigations into Lee's murder is still ongoing.

Lee, who was 43 at the time of his death, left behind a legacy as one of the founders of Cash App and the chief product officer of cryptocurrency company MobileCoin.
