It has been almost two months since the death of legendary comedian Joan Rivers and her daughter still has no answers to what caused her death. The NY Medical Examiner released Joan’s autopsy report but there still wasn’t an exact cause. TMZ is reporting that Melissa is frustrated because she cannot get answers so she is taking legal advice and suing the medical center and staff so they will have to provide sworn testimonies. This comes just after reports that Melissa will inherit over $100 million dollars- the bulk of her mother’s estate. Get more details here.
