10:12 AM PT -- The Chief Medical Examiner, Dr. Barbara Sampson, stands staunchly by the original findings. She tells TMZ, "Our investigation concluded that the cause of Mr. Epstein's death was hanging and the manner of death was suicide. We stand by that determination."
She says, "We continue to share information around the medical investigation with Mr. Epstein's family, their representatives, and their pathology consultant. The original medical investigation was thorough and complete. There is no reason for a second medical investigation by our office."
Jeffrey Epstein's family is still waiting to hear about DNA evidence to prove he wasn't murdered -- evidence they've been demanding for more than 2 months, according to the family's forensic expert.
Dr. Michael Baden, a pioneer in forensics, says the family hired him to observe the autopsy that was conducted on August 11 ... the day after Epstein was found dead in his prison cell. Dr. Baden was on FOX News Wednesday, and he confirmed something TMZ first reported more than 2 months ago.
Baden says fractures in Epstein's neck are more consistent with homicide than suicide by hanging. Specifically, he says the hyoid bone (in the Adam's apple area) and 2 bones next to his thyroid cartilage were broken ... fractures common in strangulation. As we told you, those breaks are extremely rare in hangings.
Beyond the bones, Baden says the family had asked for DNA testing results from Epstein's fingernails -- which could show if he fought back against someone choking him to death -- and from the sheets he allegedly used to hang himself. Baden says the family wants to know if someone else tied the sheets together.
Baden says, immediately after the autopsy, the Medical Examiner said more information was needed to determine the cause of death -- presumably including that DNA testing.
He says the family doesn't understand why the ME suddenly announced, just 4 days later, it was suicide by hanging -- especially because the family never got the requested DNA results.
