(CNN) — An autopsy on comedian Joan Rivers has been completed, but more studies will be needed to determine the cause and manner of her death, New York City medical examiner’s office spokeswoman Julie Bolcer said Friday.

Rivers, 81, died in a New York hospital Thursday afternoon, a week after suffering cardiac arrest during a medical procedure, her daughter said.

Rivers 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, according to the New York Fire Department.

Paramedics took her by ambulance to Mount Sinai Hospital, about a mile from the clinic, where she was initially listed in critical condition.

The outpatient clinic is now being investigated by the New York State Department of Health, spokesman James O’Hara said.

No criminal investigations are currently under way in the death of Joan Rivers, according to several New York law enforcement officials. The New York State Department of Health is investigating whether there was any malpractice by the doctors and their staff, the same officials said.
