Update
The autopsy is back, my father had a brain Aneurysm in his sleep, the reason to why he had this is undetermined. I want to thank everyone for all your thoughts and prayers, i am trying to be as strong as possible but it is hard, my mother on the other hand is a complete and total wreck, i am an only child and losing dad hit home really fast and really hard, i know i will see him again but until then i will have to deal with it best i can.
