An autopsy performed on Chicago rapper Juice Wrld has determined that he died accidentally from an overdose of oxycodone and codeine, the Cook County medical examiner's office said Wednesday.

The full autopsy results or the toxicology report has not yet been released by the medical examiner's office, but they said that the autopsy report could be made public as soon as Thursday.

The artist allegedly swallowed pills to hide them from the feds who were confiscating guns and drugs from him at the airport right before he had the seizure.

According to The Chicago Tribune, officers and agents had been waiting at the Atlantic Aviation hangar at Midway because they suspected the private plane from Los Angeles carrying the musician was carrying contraband, the sources said at the time.

Sources also told the outlet that when rapper's girlfriend was asked by police if he had any medical issues or had ingested any drugs, she told them that he takes Percocet, and "has a drug problem."
