Carrie Fisher’s autopsy report has been revealed.

Carrie Fisher’s autopsy report shows the actress had cocaine in her system when she fell ill on a plane last year, but investigators could not determine what impact the cocaine and other drugs found in her system had on her death.

Coroner’s officials ruled Fisher died from sleep apnea and a combination of other factors. A news release issued Friday mentioned other drugs were also found in Fisher’s system, but it did not provide details.
