according to the transcripts... the handler said 2 of the barrels behind the Janda/Dassey residence.
ETA: I think I might have linked it in the bones or bonfire thread. Lots of cross over information in those threads
Barrels used to burn trash which would include, among other things, animal bones. I read the dog hit on a golf cart. The same golf cart that was being used to hunt, kill and presumably carry off dead animals. I'm amazed anyone thought this dog was a reliable tool for discovering evidence.
Anyway, my initial question that I never got around to regarding a cadaver dog is moot now considering the dog hits on anything. I wonder if a new dog, reliable trained and tested, would hit on the RAV4. If it did it would prove she was laying dead in the back of that SUV which would be huge problem with the current narrative Kratz would like us to believe.
