Fans have been anxiously awaiting the results of Carrie Fisher’s autopsy, hoping to gain some insight into what caused the “Star Wars” actress’ death last month. While an autopsy has been performed, it is unlikely that the public will learn her exact cause of death — at least in the near future.

A security hold has been placed on the results of Fisher’s autopsy. It’s unclear at this time why this decision has been made. Los Angeles Assistant Chief Coroner Ed Winter confirmed the news in a statement to People magazine, telling the publication on Wednesday that neither he nor anyone else at the coroner’s office would be able to release any details surrounding the “Star Wars” actor’s death.

Winter told People it was “not abnormal” for such a request to be made. He was sure to add that the security hold did not mean that fans would never learn what prompted Fisher to suffer a heart attack, and whether that was ultimately what killed her.

“It might come off within a couple days or next week,” Winter said in his statement. “I don’t know.”

Although the results of both the autopsy and toxicology performed on Fisher, 60, are being kept a secret, her death certificate was made public on Dec. 30, 2016. As reported by TMZ, the L.A. County Coroner’s Office “deferred” the cause of death. Authorities told the publication that they needed to do more testing. At the time they found that Fisher’s cause of death was “not obvious.”

In the meantime, Fisher’s family has made an important decision regarding her funeral arrangements. Entertainment Tonight reported Wednesday that the legendary actress, writer and mental health advocate had been cremated. An anonymous source, claiming to be close with the Fisher family, told the publication that a portion of her ashes will be buried with her mother Debbie Reynolds, who died on Dec. 28, 2016 — one day after Fisher. A private memorial for Fisher is slated for Thursday, with a public ceremony being planned several months down the line.

At this time there is little to no confirmation of the details of the public memorial for Fisher. TMZ reported that her daughter, Billie Lourd, was in charge of making arrangements. It was not believed that any celebrities would be eulogizing Fisher at the ceremony, though Lourd was believed to be delivering a few words if she felt up to it. There was also some speculation that Fisher’s family reached out to Meryl Streep about possibly speaking at the public ceremony.

She was not yet believed to be a firm lock, though. TMZ reported that the family had high hopes that she would accept as Streep and Fisher were longtime friends. The “Florence Foster Jenkins” actress even once played Fisher in “Postcards from the Edge.” Fisher’s family also reportedly reached out to Mark Hamill and George Lucas, both of whom worked with Fisher on “Star Wars.”
