As an ongoing investigation, it is up to the investigating agency to release the details of an autopsy. That is really "priviledged information" if the investigation is ongoing, as there could be things in the report that only the person who did the murder would know. So the full report will not be released until the Police are ready and feel it is appropriate. The Police are directed by the District Attorney in this regard. While the spouse may be informed of the "cause of death" such as not accidental or foul play, etc, the details will only be released when the DA says it is ok. I suggest she can contact the DA in this regard and see what information they are willing to release to her.
