Cadaver Dogs: The Sherlock Bones of the K-9 Police

I once read about cadaver dogs successfully beating someone who set out to deliberately fool them - I have not been able to find it again and I worry it was an exaggeration so if anyone else knows of this and has a link I would really appreciate it.

A man planned murder and took cadaver dogs into consideration in thinking about disposing of the body. So he dug a deep pit, placed the body in it, half filled it, placed a large amount of waste meat from a processing plant in the pit, filled it and laid concrete over it. He dug similar pits with more rotting meat.

The dogs indicated and the concrete was dug though and the rotting waste meat found at which point the police thought they had indicated on the rotting meat and tried to move them on - but the dogs went back and the handlers insisted the pit be checked further - which revealed the body.

If this is true then not even pounds of other meat will shield the scent of human death and these dogs truly are amazing.
