Preliminary autopsy report leads the coroner to believe that John succumbed to the cold water and drowned. The doctor performing the autopsy said he had the heart and cardiovascular system of a 20 year old. No sign of head trauma, no sign of stroke or aneurysm. Final report will come out in about a month. Thank you for your thoughts and prayers. Jamie Imes Senior Products Marketing, Louisville Phone: 502-580-1105 Fax: 502-508-1105 jimes1@humana.com
