THE DEAD SPOT EXISTS, PLAIN AND SIMPLE!!!!!!!!!!!!!!!!!!!!!!!!!!

I shot a huge buck in Sept. and the arrow hit high, didn' t pass through. I backed out and waited 2 hours before starting the search. Looked for a total of about 8-9 hours in a small wood lot and never found him. 2 weeks later to the day he got hit by a car and killed. If the dead spot doesn' t exist how did he live for 2 weeks after the shot?
