Carrie Fisher died from sleep apnea and a combination of other factors, but investigators were not able to pinpoint an exact cause, coroner's officials said.
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 actor showed signs of having taken multiple drugs, but investigators could not determine whether they contributed to her death in December.
