To specify procedures concerning initial processing of crime scenes in preparation for collecting physical
evidence
OBJECTIVE
The purpose of this General Order is to establish clear guidelines in the collection and preservation of
evidence.
DEFINITIONS
PHYSICAL EVIDENCE: Physical evidence includes any and all objects that can establish that a crime has

perpetrator. This evidence, when presented in a court of law, will assist in determining the truth about a
fact in question.
POLICY
Any item at the crime scene that can be used to solve what occurred constitutes physical evidence. The
process of collecting physical evidence includes evaluating the crime scene, photographing and
sketching the scene, searching for evidence, and properly collecting and preserving the evidence. To
ensure this process is proper and effective, employees collecting evidence will follow the procedures
listed in this order.
PROCEDURES
PROTECTION OF THE CRIME SCENE:

obtained. It provides the investigating officer with a starting point to determine the identities of the
suspects and victims, and to piece together the circumstances of what happened during the crime.
2. Duties of the first officer on the scene:
a. Self-Protection- be sure the scene is clear of suspects or that the suspects are secure
b. Render aid to all persons in need

SU Policy No. 404 - 410.0 Page 2 ii. Preventing access to the crime scene area- the extent of protective measures must be decided on a case-by-case basis PRELIMINARY CRIME SCENE ASSESSMENT: Assessment of the crime scene allows for the determination of the type of incident to be investigated and the level of investigation to be conducted. The investigator in charge will identify specific responsibilities, share preliminary information, and develop investigative plans in accordance with departmental policy and local, state, and federal laws. The crime scene assessment allows for the development of a plan for the coordinated identification, collection, and preservation of physical evidence and identification of witnesses. It also allows for the exchange of information among law enforcement personnel and the development of investigative strategies. INITIAL SEARCH: The investigator in charge will conduct the initial search with the crime scene technician(s) responsible for processing the scene. Conducting a scene walk through provides the investigator in charge with an overview of the entire scene. The initial search provides the first opportunity to identify valuable and/or fragile evidence and determine initial investigative procedures, providing for a systematic examination and documentation of the scene. Written and photographic documentation records the condition of the scene as first observed, providing a permanent record. CRIME SCENE PHOTOGRAPHS: Before a detailed examination of the crime scene is made and before any items are moved or even touched, the crime scene should photographed. Photographs should be taken utilizing overall, medium, and close-up coverage. Detailed photographs should be taken to show items of physical evidence in the condition in which they were found. MEASURING DEVICES: Measuring devices such as forensics scales and other devices are commonly used in crime scene photography to demonstrate relative size in relationships. Nevertheless, the use of such devices in every photograph may cause admissibility problems. Therefore, when the size of an item is of significance, a minimum of two photographs will be taken- the first photograph without measuring devices and the second with measuring devices. DOCUMENTING PHOTOGRAPHS:

  1. Crime scene photographs, like other evidence, will be documented. The member taking the photographs will complete a photograph log to record the following information: a. Case Number; b. Date of the Offense; c. Date photographs were taken; d. Location of photographs e. Name of investigating officer; f. Name of person who took the photographs g. Name of the victim/suspect; and, h. Type of crime. i. Description of each photograph taken
  2. The member will note in their incident report that photographs were taken and download those photos onto the computer
