NEW YORK CITY — An autopsy on comedian Joan Rivers is complete, but inconclusive. The New York City medical examiner says more studies are needed to determine an exact cause of death.

Rivers passed away in a New York hospital Thursday afternoon, a week after suffering cardiac arrest during a medical procedure. She had been on life support at Manhattan’s Mount Sinai hospital, where she was taken after she stopped breathing at the Yorkville Endoscopy clinic on August 28.

Rivers was undergoing an apparently minor elective procedure at the clinic when she suffered cardiac and respiratory arrest.

Paramedics rushed her to  Mount Sinai Hospital, where she was initially listed in critical condition.

The outpatient clinic is now being investigated by the New York State Department of Health and has reportedly been receiving death threats.

Joan Rivers’ funeral will be held Sunday at Temple Emanu-El in New York City.
