Posted Friday September 5, 2014 12:30 PM GMT

It’s been 24 hours since she passed away and the Medical Examiner’s Office can’t seem to figure out the “cause and manner of death” for the late Joan Rivers.

Per a TMZ report, the 81-year-old comedienne died just after 1pm after being in a medically-induced coma for several days. He was initially brought to Mt. Sinai Hospital after she stopped breathing during a throat surgery at a nearby clinic.

Joan’s daughter Melissa Rivers released a statement yesterday (September 4) to inform the public of her mother’s passing.

She wrote, "It is with great sadness that I announce the death of my mother, Joan Rivers. She passed peacefully at 1:17pm surrounded by family and close friends. My son and I would like to thank the doctors, nurses, and staff of Mount Sinai Hospital for the amazing care they provided for my mother."
