It's still really surreal that Joan Rivers is actually gone.
Weeks after her untimely passing we can FINALLY know what it was that caused her death.
According to the New York City Office of Chief Medical Examiner, Joan went into a hypoxic arrest during her throat procedure which cut off oxygen to her brain therefore causing her death.
The examiner called the problem a 'predictable complication' that happened and they also found out that Joan was sedated using Propofol.
