More tests needed to determine Joan Rivers’ cause of death

Further tests are needed to pinpoint comedian Joan Rivers’ cause of death, the New York City medical examiner says. Rivers, who was 81, died on Thursday at Mount Sinai Hospital in New York. She had been in hospital since August 28 when she went into cardiac arrest during a routine procedure at a doctor’s office. The New York state health department is investigating the circumstances. Spokeswoman Julie Bolcer said the “cause and manner of death” will require further studies. Rivers’ funeral is set for Sunday at Temple Emanu-El. Services will be private and no other details were released.
