Cash App founder's murder suspect faces arraignment with new details emerging.

The arraignment for Nima Momeni, the man accused of killing Cash App founder Bob Lee in San Francisco, has been delayed for a week. Momeni's attorney asked for more time to prepare, and the arraignment was reset for May 2. Lee was stabbed to death in the Rincon Hill neighborhood on April 4, and authorities have said Momeni and Lee knew each other. Momeni has been held without bail since his arrest nearly two weeks ago, and the district attorney's office has indicated that the alleged homicide may have been premeditated.
