Here's the information that ABC News has gathered after talking to a variety of sources close to the comedian.

  • Rivers was undergoing what close friend Deborah Norville described as "a diagnostic procedure ... [to] see why her voice had gotten raspy."
  • The call to 911 from Yorkville Endoscopy came at 9:39 a.m. By 9:46 a.m., paramedics and other first responders were on scene. Rivers arrived at Mount Sinai Hospital at 10:08 a.m. She was already on life support and her condition at the time we are told was near death.
  • Norville added that Rivers had been in a "medically induced coma" for the past week.
  • According to a source briefed on the case: Rivers was under general anesthesia when she went into cardiac arrest at Yorkville Endoscopy on the Upper East Side.
  • According to a Yorkville Endoscopy spokesperson, the clinic "as a federally and state licensed facility, has the same level of life-saving and resuscitation devices (such as state-of-the-art cardiac defibrillators, airway management equipment, etc.) found in any hospital emergency room or hospital-based operating room."
  • The Yorkville spokesperson adds, "Yorkville Endoscopy has performed 18,000 procedures since it opened in February 2013. Yorkville Endoscopy has maintained an exceptional safety record that far exceeds the national average."
  • The New York City Chief Medical Examiner’s Office said the autopsy is complete but will not release results, pending the outcome of further testing.
