From LADBible:
A man who was trapped in the throes of drug addiction told how he was inspired to turn his life around after a photograph chillingly captured a ‘devil on his shoulder’.
The sinister photobomber, who appeared in the back of a snap Joe Martinez took with his wife Patty, ended up prompting the bloke, from Colorado, to get clean. Even photography experts reckon Joe’s ‘demon dog’ theory is the most plausible explanation for how the mystery intruder made its way into the image – although it is a bit bonkers.
