The musician has pleaded not guilty to first-degree murder
“All we want is justice for Celeste”
The singer was arrested two days ago for the first-degree murder of teenager Celeste Rivas Hernandez
The musician, who has pleaded not guilty, could face the death penalty or life in prison without parole
The remains of 14-year-old Celeste Rivas Hernandez were found in a car registered to the musician last year
The singer’s parents were also reportedly ordered to appear before a Los Angeles grand jury
It follows the LAPD's recent announcement that the case is now being treated as an “investigation into murder"
Autopsy findings will not be publicly shared in order to prevent jeopardising the investigation
The latest development could make pinpointing a date of death far more difficult for investigators
A source with the LAPD also alleged that the singer was not being cooperative in the investigation
