Pettit has been in custody since Sept. 4. He is among three men charged in connection with Miller’s death and each faces a mandatory minimum sentence of 20 years in federal prison and the potential for life without parole if convicted.
His attorney John D. Robertson declined comment outside court.
Citing Instagram messages sent shortly after Miller’s death in which Pettit talks with a friend about disappearing or leaving the country, a judge has kept him in custody since his initial arrest, calling him a flight risk.
Two other men, Stephen Walter, 46, of Los Angeles and Ryan Reavis, 36, of Lake Havasu City, Arizona, have also been arrested in the case and indicted on similar charges. They have not entered pleas, and it was not clear when they would be arraigned.
The indictment alleged that Walter supplied the fentanyl and cocaine that Pettit sold to Miller and that Reavis, who lived in the Los Angeles area until earlier this year, acted as a middleman for the fentanyl sale.
Pettit on Sept. 5, 2018 sold Miller cocaine, Xanax and 10 blue pills that appeared to be oxycodone but contained fentanyl after the two had exchanged text messages a day earlier, according to his indictment.
Miller’s assistant found him unresponsive in his Los Angeles home on Sept. 7, 2018 and he was declared dead soon after.
Miller’s rhymes made him a beloved and respected figure among fans, including some of the biggest names in hip-hop.
The Pittsburgh native, whose real name was Malcolm James Myers McCormick, was in a two-year relationship with Ariana Grande, who after his death paid loving tribute to him on social media and in a song.
