Welcome! Glad you are here! Great first post.
I do wonder what that little dog (looks like to me) was all about. I do know if it had come from the burial site it would not be sitting on the cinder block. They’d be preserving the evidence. My guess is it’s either a toy of JJ’s with his scent on it for the cadaver dog. It sure is ironic that it is black like JJ’s dog was. (Not sure if a cadaver dog can actually look for a live persons scent) Or, maybe it was a toy for the actual cadaver dog that was on site. Maybe
@vislaw can give us an idea. Is it even possible that one of the people working the crime scene has some superstition like bringing something like that to the scene?
ETA: I wonder if it was some sort of ceramic statue already there? I’ll look back at before pics.
