The Dog by his side - Explained
German Sheppard's are known to never leave their owners side both in life and in spirit.
The dog was his dog, Duke, the one he mentioned. He was close to death and the spirit of his German Sheppard was there for him.
There is still the unexplained strange case of the dead body on the road next to him. What he crawled around for days and then found the road exactly where one of the robbers was tossed from the vehicle and lay there dead undiscovered? I don't buy that. Especially when you consider how quickly the cop found him on the road. Why did nobody spot the body?
I guessed the ID wouldn't be his and that he would find out later. Or a least that was what we were supposed to believe. Could it be that he was one of the bank robbers and in his delusional state he created the hostage memory at the end? Did he really kill the girl?
Also when he found the revolver, it was full of empty cartridges. We didn't see him find or load any ammo. Yet he fired shots. Where did the ammo come from?
This movie was made to create conspiracy theories in my opinion. But most people don't care enough about the movie to give the theories the justice they probably deserve. So lets start here.
