Carrie Fisher Cause Of Death Revealed By Coroner's Officials

Coroner's officials released Carrie Fisher's cause of death on Friday.

From The Associated Press:

Carrie Fisher died from sleep apnea and a combination of other factors, but they could not conclusively determine what caused her death, coroner’s officials said Friday.

Among the factors that contributed to Fisher’s death was buildup of fatty tissue in the walls of her arteries, the Los Angeles County coroner’s office said in a news release late Friday. The release states that the “Star Wars” actress showed signs of having taken multiple drugs, but investigators could not determine whether they contributed to her death in December.

Fisher's daughter Billie Lourd released this exclusive statement to PEOPLE:

“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.

“She talked about the shame that torments people and their families confronted by these diseases. I know my Mom, she’d want her death to encourage people to be open about their struggles. Seek help, fight for government funding for mental health programs. Shame and those social stigmas are the enemies of progress to solutions and ultimately a cure. Love you Momby.”
