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. In light of the new scientific evidence provided by Scientology, a review was mandated by the policy manual which says 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". She traced McPherson's pulmonary embolism to her psychosis and the auto accident as major factors. Wood's review caused the review and dismissal of the criminal case concerning McPherson's death. The review was done by assistant State Attorney Douglas Crow and was outlined in the 31 page memo that he sent to State Attorney Bernie McCabe, recommending to drop the criminal case against Scientology. Crow stated that there were credibility issues with the original autopsy, including that Wood had signed the autopsy herself five months after Davis' departure, failed to examine tissue samples and did not consult clinical experts before reaching her conclusion. He also pointed out two other mistakes done by Wood such as releasing the autopsy report on an active criminal case and going public on national media. Davis changed his testimony from 1997 deposition given in the civil case to strongly disagree that McPherson was severely dehydrated. He also made a series of accusations against the Medical Examiner's Office's handling of the case and questioned their motive. Davis stated that Wood was not present during the autopsy and did not consult him when she signed the autopsy. Crow noted that Wood's credibility would be attacked due to the Medical Examiner's Office's failure to follow its own policies to preserve evidence, the release of the body for cremation before a cause of death had been determined, and the destruction of Davis' autopsy notes. The primary reason Wood gave for changing her findings was her realization that the microscopic slides of the popliteal vein and the photographs of muscle tissue in the surrounding area provided evidence of trauma which could explain the thrombus formation. She could not explain why she had not seen this before.
