Carrie Fisher’s autopsy results have been placed on a security hold.
Los Angeles Assistant Chief Coroner Ed Winter confirmed the security hold to PEOPLE, explaining that the hold will prevent the coroner’s office from releasing information “from the autopsy or toxicology reports” to the public at this time.
Winter added that the security hold is “not abnormal” and that “it might come off within a couple days or next week. I don’t know.”
He could not confirm who requested the hold or why it was requested.
According to the Los Angeles Times, a security hold is “used by various law enforcement agencies and are common in celebrity or high-profile cases.” For instance, Whitney Houston, Paul Walker and Robert Blake’s wife’s autopsies were put on security hold.
