PHYSICAL EVIDENCE MANUAL - Crime Scene Investigator Network

The purpose of this handbook is to promote the maximum use of
physical evidence in the Criminal Justice System.
The value of properly collected physical evidence followed by
examination and interpretation by the forensic laboratory cannot
be over-emphasized.
Every attempt has been made to make this handbook as current
and up-to-date as possible; however, it should be noted that the
field of forensic science is expanding at a rapid rate.
New techniques and procedures are constantly being developed,
providing new capabilities or refinements to existing capabilities.
Consequently, techniques, procedures and capabilities contained
herein may change in the future. All agencies are encouraged to
keep in regular contact with their local laboratory to keep abreast
of any such changes. In the future, this handbook will be stored on
the State Police Internet site:
http://egov.oregon.gov/OSP/FORENSICS/LawEnfResources.shtml.
Updates will also be available from the same location.
