Often, in today's court environment, it is the evidence, its collection and storage that appears to be on trial rather than the defendant. This chapter provides tried and proven guidelines for the field officer and the seasoned investigator to insure that evidence is accepted by the court. This in turn strengthens the Justice System by allowing the court and/or jury to make a determination utilizing a complete set of facts. 83.1 ADMINISTRATION 83.1.1 Availability of a Crime Scene Investigator on a 24 Hour Basis A Criminal Investigator or trained crime scene investigator will be available on a twenty- four hour basis. In determining if a criminal investigator or a crime scene specialist is needed, the following sequence should be adhered to: B.

If the officer feels that additional supplies/expertise is required, his/her immediate supervisor should be contacted. C. If, in the opinion of the supervisor, that a Criminal Investigator or Crime Scene Specialist is needed; the Criminal Investigator or Crime Scene Specialist who is either on duty or on call shall be notified and briefed on the situation.

Points of view or opinions in this document are those of the authors and do not represent the official position or policies of the United States Department of Justice. Introduction There are approximately 77,000 law enforcement and police agencies in the United States. More than 80 percent of those departments have fewer than 100 officers. The current status of crime scene response by law enforcement generally falls into two categories. The FBI, state police/department of investigation and large urban police agencies have developed highly sophisticated, extremely effective evidence response teams with extensive resources and large budgets. These teams respond to numerous scenes of various types where team personnel document and collect evidence. Most of smaller police agencies cannot afford a large crime scene investigation staff or a mobile crime scene unit to process scenes. Often detectives or even patrol officers have to carry out the crime scene process.
