i have to post this again because i'm nearly certain it's the case...
the first dogs on the scene were local dogs IIRC. These are the dogs that were
reported to "hit" on human remains.
LE ruled the hits on the woodchipper out (I know sarx has specific links that state this handy
LE then states in MSM they are bringing in new dogs.
One of our on the scene people last night spoke with one of the Hickory police about the dogs. He told her that they DO NOT HAVE HRD dogs. They only have
police dogs (which are typically trained in apprehension, protection and maybe
blood detection) and have to rely on outside sources for HRD dogs. This is VERY common. Most local LE doesn't have HRD dogs (maybe some major metro areas).
That said it is logical IMO to assume that some media or LE incorrectly stated that the original dogs on the scene
"hit" for human remains when really the dog probably alerted to the presence of blood.
