I just finished reading "finding wounded deer" by John Trout.........

....therefore I agree that probably a liver shot. HOWEVER, you say you could have hit WAYY back which could suggest a ham (ass) shot. This would also give you bright blood. This would also suggest immediate tracking to prevent clotting. John Trout claims that almost all deer he's shot in the rear have been recovered....but he gets on them right away.

I'm certain you didn't hit stomach / intestines judging by your description. Lung shot deer almost always run. If you are sure you hig AHEAD of the stomach you hit the liver and he is 100% dead in less than 2 hours....period.

Go get us some pictures please
