PHYSICAL EVIDENCE MANUAL
OREGON STATE POLICE FORENSIC SERVICES DIVISION
Preference
The purpose of this handbook is to educate our customer in the Criminal Justice System regarding the services provided by the Oregon State Police Forensic Services Division, and the recommended methods of documenting, collecting and preserving physical to ensure the best analysis results.
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. This handbook will be stored on the State Police Internet site: http://egov.oregon.gov/OSP/FORENSICS/index.shtml Updates will also be available from the same location.
