First Responder’s Check List
Crime Scene Investigations
CJ:370
“The first officer’s most important task at the scene is to prevent the destruction or diminished value of potential evidence that may lead to the apprehension of the criminal and the ultimate resolution of the crime”.
1. Recording of the time-precise notations of the time are very important, can be used for checking suspects’ story.
2. Keeping chronological record- the way things were done at the crime scene, notations lend precision and credibility to officer’s statements, if testifying in court.
3. When entering the scene: Doors-open or closed? Were they locked?
Windows- open or closed? Were they locked?
Lights- on or off? Which lights were on?
Shades, shutters or blinds? Were they open or closed?
Odor- Cigarette smoke, gas, gun powder?
Signs of activity? House clean or dirty? meal preparation?
Date and time indicators? mail, newspapers, date on milk carton.
4. Nothing at the crime scene should be moved initially, unless absolutely necessary. Protect the integrity of the scene.
5. Checking for injured persons on the scene, if an injured person is on the scene first aid should be administered immediately even if it means valuable evidence may be lost or destroyed. Officer should sketch by marking the floor or forming a mental picture of the position of the person and conditions of clothing. Also observing the movements of medical personnel and if any objects were moved.
6. Deceased person on the scene- establish certain signs of death, rigor mortis, odor, lividity, and beginning decomposition.
