Dr. Joseph Jachimczyx, medical examiner for Harris County, shares his findings following a second autopsy of Joan's remains. Despite Texas law mandating an autopsy for any person who dies within 24 hours of admission to a hospital, Sharpstown General released Joan's body to a funeral within four hours of her passing. Her remains embalmed, the hospital pathologist was unable to conclusively determine a cause of death. Joan's father, Ash Robinson, hired Dr. Milton Helpern, chief medical examiner for New York City, to conduct a more thorough examination. Per a grand jury request, a team of 12 doctors including Helpern performed a third autopsy in August 1969. Jachimczyx subsequently released this report, identifying an indeterminate "fulminating infectious process" as the cause of Joan's death. Helpern's final report, issued in April 1970, cited Dr. John Hill's home remedies and delay in seeking specialized medical attention for his gravely ill wife as contributing factors to her death.
