An investigative grand jury is now examining the case of a teenage girl whose body was discovered in the trunk of singer D4vd’s Tesla. The proceedings have been underway for several days in mid-November, according to sources who spoke with the Los Angeles Times. However, it remains unclear whether the Los Angeles County District Attorney’s Office has completed its presentation of evidence.

The role of an investigative grand jury is to subpoena witnesses and gather evidence, as explained by the Times. While it can suggest charges, it does not have the authority to issue an indictment.

Information about the grand jury’s involvement came from two law enforcement officials, and a court document reviewed by the newspaper on Monday included a reference to a “GJ number,” indicating grand jury proceedings.

The body of Celeste was discovered on September 8 inside a Tesla registered to 20-year-old singer David Anthony Burke, also known as D4vd, as reported by CrimeOnline. Initially, the vehicle was parked near Burke’s rented residence in the upscale Bird Streets area of Hollywood Hills. Police later found the Tesla at a Hollywood tow yard after local residents reported an abandoned car with a Texas license plate on September 6.

Los Angeles police found Celeste’s body on September 8, inside the Tesla registered to the 20-year-old singer, whose real name is David Anthony Burke, as CrimeOnline reported. The vehicle had initially been parked near Burke’s rental home, in the flourishing Bird Streets neighborhood, in Hollywood Hills. Police found the Tesla at a tow yard in Hollywood on after residents in the Hollywood Hills neighborhood contacted police about an abandoned car with a Texas license plate on September 6.

The vehicle had been at the lot for several days before LAPD officers made the discovery. LAPD said Rivas’ body had been put in a bag and left in the front trunk, and police say the girl had been dead for several weeks before the car was towed.

The girl’s body was found the day after what would have been her 15th birthday.

On Monday, a judge placed a security hold on the case barring details — including the cause and manner of death and the autopsy report — from release, following a court order initiated by the LAPD on Friday.

It was that document that referenced the “GJ number,” according to the Times.

Although police have not called Rivas’s death a homicide, the document called the investigation “an investigation into murder.”

One of the law enforcement sources told the Times that Deputy District Attorney Beth Silverman called several witnesses before the grand jury.

Sources have said that investigators believe more than one person was involved in handling the teen’s body before her remains were ultimately found, and LAPD Deputy Chief Alan Hamilton said this week that “accountability is coming.”

“Our RHD detectives have been working … They are going to get justice for Celeste Rivas,” Hamilton said. “No one is off the table, including him,” referring to D4vd.
