Carrie Fisher's coroner case has been placed on a security hold, ET has learned.
Following news that the legendary Star Wars actress -- who died late last month at the age of 60 -- was cremated, Ed Winter, Los Angeles Assistant Chief Coroner, confirmed the security hold to ET on Wednesday, noting that the hold will bar the department from releasing any information to the public at this time.

Winter told ET that it's "sometimes" normal to put a security hold on a case, which could delay the release of information to a week or so longer, "when it's a high-profile case or if there's something they're looking at."
Winter did not elaborate further or confirm who requested the security hold, or if the death was currently being investigated.
According to the Los Angeles Times, a security hold is "a directive from detectives [usually in writing] to the coroner's office not to publicly disclose details from an autopsy, notes written by coroner's investigators or results from toxicology and other tests," and is "used by various law enforcement agencies and are common in celebrity or high-profile cases," like the deaths of singer Whitney Houston and actor Paul Walker. Detectives later notify the coroner's office by letter when it can be released.
Earlier in the day, a source close to the Fisher family told ET and the The Insider that a private memorial will be held for the iconic actress on Thursday. Fisher's mother, Debbie Reynolds, who died on Dec. 28 (one day after her daughter) at age 84, will be laid to rest in Los Angeles, along with some of Fisher's ashes. The source also revealed that a public memorial is being planned for months down the road.
