Assignment Instructions:
Forensic science begins at the crime scene. Based on the Locard principle, even the actions of the Crime Scene Investigator (CSI) may be destructive to evidence found at the scene. It is imperative that the actions of the CSI mitigate damaging the evidence as much as possible during collection, field processing, and packaging of the items seized as evidence. Obtaining the evidence as close to its original condition when found should be the goal of the CSI.
Discuss the following in your main post:
What is the responsibility of a Crime Scene Command Center? Who mans the center?
What is the best procedure to follow when a nighttime crime scene is too dark to search properly? What steps should an investigator take if circumstances do not permit this procedure?
The third walkthrough of the crime scene is considered the final survey of the crime scene. Who does the third walkthrough/final survey, and what are they looking for?
How To Work On This Assignment(Example Essay/Draft)
The crime scene is where forensic science gets its start in the investigation of crimes. A CSI must take precautions to prevent any damage to the evidence throughout collection, field processing, and packaging because the Locard principle states that even CSI actions can affect the evidence discovered at the scene. Finding evidence that is as close to its original state as possible is the ultimate goal of a CSI.
The personnel and resources needed to conduct a crime scene investigation must be managed and coordinated by a crime scene command center. A senior detective or forensic expert are typical members of the law enforcement community who staff the center. Task delegation, proper evidence management and processing, and necessary coordination with other law enforcement officers are among their duties.
The best course of action is to postpone the search until after dawn or to employ alternate light sources, such as flashlights or portable lighting equipment, when a crime scene is too dark to search effectively at night. If, however, the situation does not allow for this approach, the investigators should take comprehensive notes and pictures to fully record the scenario. In order to learn more about the scene, they need also employ their other senses, such as touch and scent.
A senior investigator or forensic specialist usually conducts the third walkthrough/final examination of the crime scene. At this phase, they hunt for any further evidence that might have been overlooked during the initial searches and check the correctness of the earlier notes and photos. They might also be on the lookout for indications of tampering or other odd behavior that might give some light on the crime. The objective is to make sure that all pertinent information has been gathered and recorded and that the site is left in a secure condition for others to visit.
In conclusion, forensic science is an essential part of a criminal investigation, and a CSI’s activities can make or break a case. The investigation is coordinated and managed by a crime scene command center, and by adhering to the best practices for evidence collection and doing extensive walkthroughs, it is possible to assure that no evidence is missing. All of these initiatives ultimately aim to provide the victim with justice and comfort for their loved ones.
