The Triangulation Method.
All of these should be treated as evidence. If any doubt exists as to the value of
an item, it is treated as evidence until proven otherwise.
This same careful attention is required to protect items or areas where
fingerprints may be present. Actions should be taken to have the prints lifted and
developed.
Impressions in the surface (such as tire tracks or footprints) must be protected.
Casts or molds should be made as soon as possible.
NOTE: Particular attention must be given to trace evidence.
Trace evidence is
evidence that may be destroyed or altered if it is not collected immediately.
Trace evidence includes--
o
Hair (human, animal).
o
Fibers (carpets, clothing, furniture).
o
Earth particles (mud from shoes).
All of these types of trace evidence can be destroyed or easily overlooked.
