Some believe that there are angels amongst us.  If that is true, wouldn't it stand to reason that there are devils as well?

Joe Martinez thinks so, and has the picture to prove it.

Eight years ago, while attending a wedding anniversary, he and his wife had their picture taken.  Recently, while going through photo albums, they noticed an eerie presence lurking over his left shoulder.  It appears to be a dog, or, a hound from hell, if you will.

At the time, Mr. Martinez was in the throes of addiction and claims this photo helped to save him from death.

Photo analysts and experts on the paranormal have no explanation for the image.
What do you think?  Is it real?  Do you believe in the spirit realm?
