The report was released Monday after sheriff's officials released a security hold.
Sheriff's spokesman Steve Whitmore said the agency has known about the findings in the newly released autopsy report for several months and it does not change the status of the investigation, which remains open. He said Wagner is not considered a suspect in Wood's death.
Wood was nominated for three Academy Awards during her lifetime. Her death stunned the world and has remained one of Hollywood's most enduring mysteries. The original detective on the case, Wagner, Walken have all said they considered her death an accident.
