New details revealed as D4vd named target in Celeste Rivas murder case

\

New court documents are revealing details into the murder investigation of Celeste Rivas Hernandez, and confirm singer D4vd as the investigation's target.

The documents – which show the legal fight as a California grand jury petitions the parents of D4vd, born David Anthony Burke, to travel from Texas to potentially testify – come after the mysterious death of the young teen. Hernandez was found in the trunk of a Tesla registered under the musician's name in September, over a year after she went missing, after reports of a foul odor coming from the car. Her human remains were found inside a bag located in the front trunk, ABC and NBC reported at the time.

The Rivas Hernandez was likely dead for "several weeks" before her body was discovered, according to a statement the Los Angeles Police Department's Robbery-Homicide Division previously shared with USA TODAY.

The singer has not been arrested or charged. A representative for D4vd, 20, previously told NBC that the "Romantic Homicide" singer was "fully cooperating with the authorities," though it is unclear if that is still the case.
