The remains of the Mexican music superstar arrived at Long Beach Airport by private jet on Thursday evening. Her casket was then driven to a mortuary, where dozens of fans waited.
Other fans gathered outside her family's home in nearby Lakewood, where well-wishers have left a memorial of photos, candles and flowers.
Rivera and six other people died Sunday evening when a plane she was traveling in nose-dived to the ground while flying from Monterrey in northern Mexico to the central city of Toluca.
The cause of the crash remains under investigation.
