The investigation into Mac Miller’s untimely passing continues.

According to TMZ, Stephen “Stevie” Walter was arrested on Monday (Sept. 23) in Los Angeles. According to the court documents, Walter was contacted by Cameron James Petit on the night of Sept. 4, 2018, a few days before Miller’s death on Sept. 7. According to their exchange, Miller asked for “10 blues,” which translates to Percocet pills.

Following their conversation, Petit contacted Walter to obtain the pills. After, Walter sent a runner to Petit with the pills. During their investigation of Miller’s death scene, cops found a magazine in his bedroom covered with blue-colored powder and indentations near a rolled piece of paper. Cops say that the scene indicated that Miller crushed or snorted one or more pills.

On Wednesday (Sept. 25), the F.B.I. arrested Reavis after finding drugs in his home including prescription-only pills and marijuana. In addition to that, cops found a physician’s prescription pad, confiscated firearms including a 9mm pistol, two shotguns, a homemade firearm suppressor and an arsenal of ammo.

Earlier this month, Petit was arrested for giving Miller the wrong pills, which cops believe led to his death. According to NBC News, Petit supplied Miller with counterfeit oxycodone pills containing fentanyl. As the case continues to unfold, many have shared their thoughts on the unfortunate situation.

“So they finally caught the muthaf–ka that sold him the drugs that killed him,” Mark McCormick, Miller’s dad, said after hearing about Petit. “And we find some comfort in that. Many of us who were young, including me, experiment with drugs. But it’s a different f–king world out there. All it takes is a little tiny stone of Fentanyl and cocaine and you’re dead.”

More recently, it was reported that Miller left behind valuable items which include $1.5 million in music royalties, $180,000 in Mac Miller LLC, an extensive jewelry collection, household furniture and electronics. All of the items total around $7 million.
