Water Recovery
Nearly immediately after death by drowning, a body will begin to
decompose and release gases which rise to the water's surface.  It is
these gases that the HRD dog is trained to detect.  The same is true for
human remains that are maliciously deposited, either intact or in pieces,
into a waterway.  CSS has indications in depths of up to 100 feet. The
deepest recorded find by an HRD dog was in Idaho, in water over 300
feet deep.

When requesting a water search, CSS will need to be provided with a
boat and driver.  The handler will utilize GPS and record areas of
indication.  Coordinates and a map of the area will be provided, along
with further information on tools available to assist law enforcement in
the event of a difficult or challenging recovery.
