The medical examiner's office says more information is needed

An initial autopsy on Joan Rivers has been completed, but officials say the cause of death remains unclear.

"Following an examination, cause and manner of death is pending further studies," Julie Bolcer, spokeswoman for the New York City Medical Examiner tells The Hollywood Reporter. "I wouldn’t say inconclusive. That’s a classification for when we can’t determine what happened."

The 81-year-old grand dame of comedy died at Mount Sinai Hospital Hospital in New York on Thursday after being taken off life support. She had entered the hospital the previous week after a procedure for her throat at Yorkville Endoscopy in Manhattan.

The New York State Department of Health has opened an investigation into Rivers' death.

Asked if the medical examiner's office was working with the DOH, Bolcer said, "They are separate investigations. If asked, we will cooperate as necessary."
