The CADAVER dog... and her walking.... that dog is not good at it's job if that is the case, just sayin... LOL
The dog did hit on other vehicles.... but there is vehicles there that were in accidents.... some possibly fatal.
A cadaver dog, to my understanding, only hits on human remains or the smell. Tracking dogs only follow scents they are given to find and I haven't heard a tracking dog was used. If not, a real missed opportunity to see where she walked or if she was even in the trailer.
