The detective assigned this murder investigation has never handled a homicide. As she drives you to the scene, you begin to assess the things you already know, and you start to formulate a plan for the crime scene search. Using the two crime scene sketches provided here for interior and here for exterior, write a proposal for how the crime scene should be searched. Identify the areas that will be searched and what type evidence you might expect to find in those areas. Create a set of instructions for all of the department personnel who will be available and assign them roles.
Paper For Above instruction
The investigation of a homicide scene requires meticulous planning and systematic execution to ensure that all potential evidence is identified, collected, and preserved properly. Given that the assigned detective has limited experience with homicides, a comprehensive and detailed crime scene search plan is essential. This plan should incorporate both interior and exterior scene sketches, ensuring every relevant area is thoroughly examined while maintaining the integrity of evidence.
Interior Crime Scene Search Plan: The interior scene, as depicted in the sketch, encompasses the primary area where the victim was found, likely including adjacent rooms or corridors that might hold evidence such as fingerprints, bloodstains, or personal belongings. The search should commence with a logical, methodical approach, such as a grid or point-to-point search. Each team member should be assigned specific zones based on the sketch, ensuring overlapping coverage to prevent any lapse. Evidence of interest includes blood spatters, weapon location, footprints, or any items that might indicate the sequence of events.
Specifically, the room should be divided into sectors, with personnel assigned to search each sector. Items should be photographed in situ before collection. Areas around entry points should be scrutinized for fingerprints or footprints. Any items that could bear fingerprints or DNA should be carefully collected in appropriate containers. The process includes documenting the location and condition of all evidence, as well as conducting a systematic search of furniture, fixtures, and surfaces for traces of blood, hair, fibers, or other trace evidence.
Exterior Crime Scene Search Plan: The exterior sketches highlight relevant zones such as the perimeter, entry and exit points, nearby objects, or potential hiding spots. An initial search around the perimeter provides an overview of the scene, including any disturbed soil, footprints, tire marks, or personal items left at the scene. Similar to the interior, the exterior should be searched using a grid or spiral method, ensuring each zone is thoroughly examined.
Special attention should be paid to footprints or tire impressions, which could help establish movement patterns. The surrounding foliage, nearby structures, or vehicles should be examined for evidence like hair, fibers, or discarded weapons. All evidence should be documented meticulously, with photographs taken from multiple angles. Items such as personal belongings, weapons, or footprints should be collected and packaged securely to prevent contamination.
Personnel Roles and Instructions
- Lead Investigator: Oversee the entire scene search, ensure protocols are followed, and coordinate evidence collection.
- Photographer: Capture comprehensive photographic documentation of the scene before and during searches.
- Sketch Artist: Update or create detailed sketches reflecting evidence locations and scene layout.
- Search Team Members: Divide into interior and exterior teams, each responsible for designated zones. Follow the systematic search procedures outlined, report findings immediately, and assist in evidence collection.
- Evidence Collectors: Carefully gather, label, and document evidence, ensuring proper packaging and chain of custody.
- Safety Officer: Ensure all personnel adhere to safety protocols, PPE use, and scene preservation standards.
Instruct all personnel to maintain integrity of the scene at all times. Evidence, once collected, should be transported in secure containers and logged into the evidence database. Communication among team members should be constant and clear, with regular updates to the lead investigator to adapt the search strategy as needed.
Conclusion
A well-structured, step-by-step approach combining interior and exterior searches, precise documentation, and clear personnel roles is vital for the success of this homicide investigation. Proper execution of this plan will maximize evidence recovery and ensure procedural integrity, ultimately aiding in solving the case efficiently.
