The Los Angeles County coroner's office on Friday listed the cause of death for "Star Wars" star Carrie Fisher as sleep apnea and other factors, including drug use.
The coroner's office released a short summary of its findings, but officials declined to make any additional comments. The statement said "the manner of death has been ruled undetermined."
In addition to the listed cause of death, the coroner's statement cited "other conditions: atherosclerotic heart disease, drug use."
It also said: "How Injury Occurred: Multiple drug intake, significance not ascertained."
The report does not clarify the role drugs played in Fisher's death. But her daughter, Billie Lourd, issued a statement to People magazine Friday night linking her mother's death to drug use.
"My mom battled drug addiction and mental illness her entire life. She ultimately died of it. She was purposefully open in all of her work about the social stigmas surrounding these diseases," Lourd told People.
Fisher's brother, Todd Fisher, said he didn't think there was anything new in the coroner's brief statement.
