OMG!!! That is so sick, and you have to wonder this guy's thought process. What the hell is he thinking??? "Oh, that's a cute little bunny...nice tail" ha ha ha. Oh, and the visual? This guy needs some serious help.
TIS, (I learned this at my job) some small animals body's spasm uncontrolably when they die. So he probably used the bunnies for sex and then killed it as he was yeah you get the idea. That would explain all the dead rabbits.
I hope he rots, sick fuck. Who could really hurt a bunny? God, if there is any justice, I hope they put a rabid rabbit in his cell and tie him up so the thing can gnaw at his testicles. That would be ironic, and justified, I think.
