The footnote marks the first time a case against D4vd has appeared in Rivas's death investigation. There are no public filings related to the case, and the grand jury proceedings have been kept under wraps. An anonymous source told the Los Angeles Times that the proceedings were described as an 'investigative grand jury.' A document submitted to the court by LAPD Detective Joshua Byers in November also referred to the case as 'an investigation into murder,' the LA Times reported. The document was a petition to bar the LA County medical examiner from making Rivas's autopsy results public or speaking about the results. Rivas's family said she left to see a movie with D4vd in the spring of 2024 and never returned. Her body was found in the singer's car in September 2025. She's pictured above in a photo shared on social media The medical examiner's office removed the case from the department's website in November. Neo Langston was arrested earlier this year for failing to show up in court The coroner confirmed to media outlets at the time that they received a court order to place a security hold on the case, and Rivas's cause of death was never released to the public. Grand jury testimonies have also been sealed, but sources have previously said that D4vd's tour manager, Robert Morgenroth, and streamer friend Neo Langston have both testified, according to TMZ. Langston was arrested in Montana earlier this year after failing to appear in the California court as a witness. Sources told TMZ at the time that police in Helena assisted the LAPD's Robbery-Homicide Division with the arrest. It's unclear why prosecutors have called D4vd's family to testify. The Daily Mail has reached out to Dawud and Colleen for comment. Their representation wasn't immediately made available. Riva's body was found in the trunk of D4vd's Tesla at a tow yard in Hollywood. The vehicle is pictured getting towed after the gruesome discovery D4vd hasn't been formally charged in connection to Rivas' death. Prior to the incident, he was an up and coming music star and is pictured at Paris Fashion week on June 26, 2025 The family has kept a low profile since Rivas's death, but the Daily Mail obtained photos of Colleen in September at a Texas pawn and gun store. Documents obtained by TMZ in October claimed that D4vd transferred the deeds of two of his homes in Houston to his mother. The real estate documents reportedly revealed that the first transfer occurred on September 18, just one day after authorities raided his Hollywood Hills rental. Police in Texas also responded to a report on September 18 of a reported squatting incident. A 911 caller falsely claimed a shooting happened at the home, but police body camera footage revealed D4vd notifying authorities when they arrived that everyone was alive and well in the home. The second transfer was recorded just a few days later, on September 22.
