~snip~Does anyone know how long cadaver dogs can smell the cadaver scent after the body is gone? Weeks, months, years?
if a lot of time has elapsed since the body was removed from the scene. Cadaver dogs can find the remains of people who have been dead for years or even decades. But it's much harder for the dogs if the bulk of the remains are gone. In that case, they can pick up the scent from small amounts of body tissue, like a blood stain or nail clippings, or even from materials that came into contact with the tissue. But in the absence of an actual body, the smell of death will dissipate..............
Researchers are trying to determine how long the scent lingers when the body is no longer present, but there are no conclusive results yetit may be two weeks, or it may be longer. One former Scotland Yard dog handler talking about the McCann case hypothesized that the scent wouldn't last more than a month.`~snip`~
