The avenging prankster who runs the DamienEchols93 Twitter feed recently posted various accounts of young Damien’s treatment of animals. This eventually got a rise out of Damien Echols himself, who dismissed “the animal lies”. The whole thing is documented here: Damien Echols Responds to Animal Cruelty Claims.
I’ll just add that all of this information was available to the Paradise Lost filmmakers, who chose not to include any of it. However, the first film did address the animal issue. At around the 8:00 mark in Paradise Lost: The Child Murders at Robin Hood Hills, Joe Hutchison, father of Damien Echols, says, “This boy is not capable of the crime that he’s been arrested for. I’ve seen him take a little kitten and love it just like you love a little baby.”
So who you gonna believe?
