Its all water under the bridge now, as new testimony will not be allowed in the retrial of the penalty phase. Like others, I am disappointed in the overall lack of detail in the autopsy report. Horn's explanation of the error with respect to the dura mater is credible; in some of my medical records, I have similar types of errors where the physician failed to override common findings that are automatically included in the report.
Because of the controversy that this has stirred up, I believe that more than one forensic pathologist will review all of the autopsy records to better explain whether or not the bullet passed through Travis's brain. Xrays will be an important part of reconstructing the bullet's path. This may happen once the trial has ended and evidence records become available to the public.
In the long run, it doesn't matter to me whether he was shot first, second or last. The amount of injuries she inflicted on him was significant and IMO, showed intent to inflict pain and death.
