Red herring? What do you mean?
I've followed this case for awhile but am refreshing my brain on it. The dry cleaner shirt js related to a bloody shirt that was the father-in-law's correct? I can remember it vaguely and it involved 2 dogs getting into an attack and one dying? I hope I didn't just make up a story like that lol. But I remember it all seeming to resolve without having anything to do with the murder.
