In the article "Examination and Documentation of the Crime Scene" written by George Schiro, he discusses the examination of a crime scene using photography. He states how photography can be used to compare different situations. One example he gives is how actual size photos can be used to compare shoeprints and fingerprints found at the crime scene to possible suspects. These actual size photographs are also known as one-to-one photos. Schiro states in the article that this is an advantage of photography over videography. The article goes on to say how photos should be taken at the crime scene. First shots should be taken from a wide angle of the scene and the surrounding areas. A good strategy is to shoot the crime scene from all four …show more content…
Schiro states, "Videotape can provide a perspective on the crime scene layout which cannot be as easily perceived in photographs and sketches. It is a more natural viewing medium to which people can readily relate, especially in demonstrating the structure of the crime scene and how the evidence relates to the crime." This article goes on to say how moving slowly is a major key to videotaping a crime scene. This helps to reduce the chance of a crime scene investigator to skip over key evidence due to moving too quickly (Schiro, 2016).
In the article "Written Documentation at a Crime scene" written by Mike Byrd, he discusses the importance of note taking at a crime scene. Notes initially taken at a crime scene are later turned into a final report. The notes and reports should involve no opinions, no analysis, or no conclusions. They should be done in chronological order and just include facts only. Investigators at the crime scene need to take notes on what he or she sees at the scene and leave out his or her conclusions. The final report should in the end give a detailed description of the crime scene (Byrd,

Boots, he writes about the use of hand and laser measurement devices used at crime scenes. One hand held measurement method that Books writes about is a rolling measurement device. This type of device should be checked against a steel tape measure to compare over various distances. Boots states, "Probably one of the most commonly used devices is a good old-fashioned tape measure. It is recommended to use steel tape measures as opposed to those made of fiberglass. Steel tape measures tend to be more durable and have a longer life expectancy than fiberglass. Additionally metal tapes will not stretch like fiberglass." (Boots, 2014). Other than a tape measurer, an investigator may use a handheld electronic measuring device (Boots,

    The first thing I would do in processing the crime scene is interview the first officer that arrived at the crime scene to establish a theory of the case. Second I would examine the crime scene to see if the theory of the case is substantiated by what I observed. During this time I would start identifying possible items of evidence, identifying entry and exit points and getting a general outline of the homicide scene. Third, I would take some pictures. Photographing the scene would allow me to record a pictorial view of what the scene looked like undisturbed and to record items that is possible evidence.…

    Afterwards, another walk through will have to be conducted, but along with a crime scene photographer. The duty of the crime scene photographer would be to photograph the scene and anything that may be used as vital evidence. The significant manner that the photographer would have to capture the essence of the scene would be by taking multiple photos of the overall scene and close-up photos with and without a measuring ruler. A view of the crime scene should be taken from a number of different angles and distances, including photos of bodies (no matter how gruesome). The reason for photographing the scene would be to display how it was before evidence was collected.…

    The sketch can have its advantages because it shows the scene in its actuality. The investigator needs to make sure his name, rank, date, time, type of crime, case number, additional officers assisting with sketch, scale and legend are all documented on the sketch.

    Introduction: Offender profiling can be defined as making predictions about offender’s characteristics from the way they behaved during a crime (Davies & Beech, 2012). Offender profiling can play an important part in criminal investigations, especially when there is no DNA left at crime scenes. It requires using other types of evidence such as characteristics of the crime scene and eye-witness testimonies from victims and witnesses. Profiling techniques can be unified with police forces to help elicit and prioritise suspects and may predict what an offender may do next (Canter & Youngs, 2009). However, it’s important to assess the reliability of such psychological procedures as they are frequently applied to serious and violent forms of crime…

    The more detailed your notes are, the better it makes for evidence. Upon arrival to the crime scene the officer must have knowledge of the proper way to black of this type of crime scene.

For example, in a murder scene you might block off the street whole house depending if the crime occurred in the house. If it occurred outdoors, they may block off the entire block of where the crime occurred.…

    This behavior happens for two reasons, as noted by Douglas and Munn (1992a), to re-direct the investigation or to protect the victim or the victim’s family. When the offender makes these alterations they don’t know what they are doing and make things obvious for investigators. The following are some examples of staging: when items are missing to show that it was a burglary gone badly and there are no signs of forceful entry, when a body is moved to another place to make it seem that the person at other place committed the crime, or when they try to make the crime scene look like a suicide. Crime scene staging help investigators focus on the victims closes friends or relatives. 6.…
