Here's a link to the story at The Detroit Free Press.
This is a story about some real heinous people, and has some photos of the dogs that were rescued (which are not all "Pit Bull" -- and include one small fluffy dog that was probably going to be used for bait). Two dogs were fatally wounded in fighting. The participants are residents of both Michigan and other states.
Too disturbing. I need to find some happy stories and do a happy post.
