  After V1 sank Victim was found floating face down approximately 3/4 of a mile from site of accident.  The autopsy report received from Monroe County Medical Examiner summarized Victim's cause of death as;  "The decedent was found to have no evidence of severe or significant acute trauma.  The decedent has pulmonary edema.  Coronary artery disease is severe.  Postmortem toxicological analysis of blood reports:  Ethanol = 0.195% (w/v).  Therefore, based upon the information available to me at this time it is my opinion that the cause of death is best certified as Drowning with the manner of death classified as Accident.  Atherosclerotic cardiovascular disease is a contributor."
