CRJS406(1) - Research Paper Example

This entails establishing barriers, which will ensure that every crucial piece of evidence is maintained, in addition to sealing all entrances and exits to control entrances while excluding nonessential personnel and bystanders. The management of physical threats will make certain that safety of evidence and those authorized to be in the scene are handled in a secure manner. The barriers can comprise scene tape, vehicles, law enforcement officers, and barricades. Thirdly, a log is created which notes every person who crosses the barrier including the instances in which they come in and exit.

This involves recording clear and succinct information regarding the preliminary observations and events. The aim of this documentation is to acquire information that will corroborate investigative considerations (Hess & Orthmann, 2009). Notably, the official investigators entering the scene need to wear proper protecting clothing, comprising a collection of overalls, facemasks, paper shoes, and latex gloves. After leaving the scene, every protecting clothing needs to be analyzed in order to avoid the danger of losing precious trace evidence (Hess & Orthmann, 2009). . Every crime incident leaves out some traces at the scene, and since most of the traces are normally transient and brittle, when disturbed can destroy their reliability and preservation.

Securing the scene will help the investigators to appropriately deduce details, in order to reconstruct the events that took place. Therefore, the goal of securing the scene is preserve the physical integrity of the traces (Sutton & Trueman, 2013). Walkthrough Walk-through is the first assessment conducted by an investigator by vigilantly walking through the scene in order to assess the state of affairs, identify likely evidence, in addition to determining the resources needed (Hess & Orthmann, 2009).

The intention is to recognize threats to the crime scene integrity in order to safeguard the physical evidence. Even though the goal of Walk-through is to mentally prepare the premises regarding the reconstruction of scene, the theories can and should change as investigation advances (Dutelle, 2011). During the initial walkthrough, the primary responsibility before else is to reduce scene contamination. This entails establishing both entry and exit points, and the pathway. The other role of walkthrough is to determine the necessity for individual protective equipment before entry, followed by a documentation of the scene as initially observed.

The objective is to recognize and protect fragile evidence, and it involves evaluating the crowds or hostile environment. It also entails a concluding survey, whose objective is to affirm that the scene has been effectively and entirely processed (Dutelle, 2011). Documentation The objective of crime scene documentation is to generate enduring and objective traces of the scene, including the physical
