First coroner's report On December 5, 1995, McPherson's autopsy was conducted by assistant medical examiner Robert Davis. Davis never completed McPherson's autopsy report because he was asked to resign from his position. The report identified McPherson's cause of death as a
thromboembolism of the left
pulmonary artery caused by "bed rest and severe dehydration", ruling the manner of death as "undetermined". The report also identified multiple bruises, an abrasion on the nose,
lesions and insect bites that appeared consistent with that of a
cockroach. The autopsy report was completed by Davis’s supervisor, medical examiner Joan Wood. On January 21, 1997, Wood appeared on the news program
Inside Edition and stated that the autopsy showed McPherson's condition had deteriorated slowly, going without fluids for five to ten days, was underweight, had cockroach bites and was
comatose from 24 to 48 hours before she died. Scientology's legal team proceeded to sue Wood to gain access to her files; including tissue, organ and blood samples from McPherson's body. The lawsuit argued that Wood waived any right to keep her records on the case closed when she spoke openly about the case with news reporters. Scientology alleged that the records were needed to start their
legal defense. These records were previously denied to the Church because they were part of an ongoing criminal investigation.
Independent opinion The
St. Petersburg Times contacted five medical experts for their opinions about the report, and they confirmed Wood's opinion. Scientology responded that the five doctors should have been given the entire autopsy report, not just the
vitreous fluid tests, which pathologists use to determine the composition of blood at the time before death.
Scientology hired forensic pathologists Scientology hired its own team to oppose Wood's findings, including two nationally known
forensic pathologists: Dr.
Michael Baden, a former chief medical examiner for
New York City; and Dr.
Cyril Wecht, a county coroner from
Pittsburgh, Pennsylvania. Baden and Wecht concluded that McPherson died suddenly and unpredictably of a blood clot in her left lung that originated from a knee bruise she suffered in the minor car accident seventeen days earlier. This scientific evidence was then sent to Wood for review. The scientific evidence sent to Wood included: • Research on compounds known as
ketones, which people produce when they are dehydrated, starving or even fasting. Tests of McPherson's bodily fluids showed no ketones according to the pathologists. • A report by Robert D. Davis, the pathologist who conducted the autopsy for Wood's office, concluded McPherson's body was of average nutritional status. Due to the vitreous fluid tests, Baden and Wecht maintained that McPherson was dehydrated. Chemical pathologists Calvin Bandt and
Werner Spitz concurred with the initial coroner's report in their
affidavits. Plaintiff witness Dr. Alan Wu also testified that ketones need not be present for dehydration in a special case like McPherson where she was fed proteins and therefore didn't create measurable ketones. The plaintiffs maintained that McPherson did lose water weight to result in with respect to the vitreous fluid.
Final coroner's report In light of the new scientific evidence provided by Scientology, a review was mandated. The policy stated that the medical examiner will "readdress key issues" in a case if "credible new evidence is presented, regardless of its source." After the review, Wood changed the cause of death from "undetermined" to an "accident." Wood stated that McPherson's psychosis and auto accident were major factors to the development of the fatal pulmonary embolism. ==Criminal case review==
