Crime scene Reconstruction

Question one

Crime scene team members and their duties.

1. Team Leader

The team leader controls all the activities of the team. By taking control of the group, the team leader ensures that they are safe and their security is guaranteed by providing that the team members use protective equipment and observe the standard recommendations so that they may be protected from any health hazard present at the crime scene. The team is responsible for conducting the initial walk to do initial surveys, examining the potential evidence and preparing a narrative description.

1. Photographer and Photographic Log Recorder

The photographer is always responsible for taking photos of the whole crime scene and picture of the crowds, victims and other items in the crime scene, which can be used as evidence.

1. Sketch Preparer

The Sketch Preparer is always responsible for sketching the crime scene to ensure that important administrative information such as scale declaimer is recorded on the diagram.

1. Evidence Custodian

The evidence custodian is always responsible for storing the collected evidence at the crime scene in appropriate bags or envelope

Question two

Some of the search patterns used in analyzing a crime scene include zone pattern, grid pattern, parallel search pattern and outwards spiral pattern. The zone pattern requires the crime scene team member to divide the scene into sections, and every team member is given a part to analyze. The grid method is the same as the parallel method (Baxter, 2015). However, it requires the team members to investigate the scene on a bearing of 90 degrees. The outward spiral search pattern requires the investigator to examine the crime scene from the centre and work their way outward in a spiral to the edge. There is also the inward spiral search pattern which encourages investigators to start analyzing the crime scene from the edge of the scene moving towards the centre in a spiral.

Question three

Some of the pieces of evidence that may be collected from a crime scene include trace evidence which includes items such as gun-shot residue chemicals, glass and illegal drugs. They should be stored in sealed bags and then transported to the lab for screening. Body fluids such as saliva, semen, vomit and blood at the crime scene can be collected as a form of evidence. The team members can collect these pieces of evidence by using smear slides, tweezers, a scalpel or sterile cloth squares. The team can use a blood collection kit to collect and store blood samples (Kwon, Mohaisen, Woo, Kim, Lee & Kim, 2016). Fingerprints can also be obtained from the crime scene. Some of the tools used for recovering fingerprints include chemicals, lift cards, powders and a magnifying glass. The team can also collect firearms, casings and bullets at the crime scene. These pieces of evidence should be collected after wearing gloves, and they should be put separately for lab analysis.

Question four

Some of the procedures for securing and searching a crime scene includes conducting a view walkthrough, securing and isolating the crime scene using tapes, confirming or pronouncing the victims’ death and excluding all unauthorized individuals from the crime scene. The procedures for searching the crime scene includes documenting the crime scene by taking photos of the crime scene. The photographs should be taken in an altered situation. The next procedure involves sketching the crime scene. The crime scene sketches include making rough sketches of the crime scene. The third procedure consists in searching the scene. The crime scene should be examined for any available evidence that may be used to understand the crime and how it occurred.
