By secure the scene to ensure that no evidence is misplaced or damaged, or otherwise compromised. Do a cursory check of the crime scene to obtain any transient evidence and secure any weapons found at the scene (in this case it was already at the scene with the suspect). Crime scene analysts and investigators communicate with first responders and are quickly briefed on the situation, and now a more thorough search can be conducted. A scene search is necessary to find evidence such as shell casings, biological evidence etc. At the time, a more detailed, extensive search will begin.
A strategy that criminal investigators should take in order to conduct an efficient follow-up investigation is to ensure all observations and notes are shared from the officers that conducted the preliminary investigation to the officers that are conducting the follow-up. This could eliminate potential time wasting activities that had already been addressed by the first officers on the scene. Using paperwork that is consistent can allow for easier communication for these two separate investigations in case there are other officers working the case. This paperwork would let the follow-up investigators know what steps were followed during the preliminary, and if they had not been ... ... middle of paper ... ...sted following up on something that was already checked. Different crimes will be reported and handled in a different fashion, even among the different major crimes that are committed.
The purpose of crime scene investigation is to help establish what happened at the crime and to identify the responsible person or people. Carefully documenting the situation at a crime scene and recognizing all-important physical evidence do this. The ability to recognize and properly collect physical evidence is often times vital to bo... ... middle of paper ... ... keep tract and record everything in which they recover from a crime scene. Searching a crime scene is a long and thorough process, however, it will surrender many clues when done properly. Once the evidence is found, recorded and packaged, it must be sent to a crime lab for further processing.
This evidence is send to forensic laboratories to be examined and provide the investigator with information that may help solve the case. Later on this information can be used in court, for this reason it is critical that the investigator gather the evidence properly and legally. Most police investigations begin at the scene of a crime with the first responders to the crime scene usually police officers, fire department personnel or the emergency medical personnel. Their actions of the first responders to the crime scene can help the investigation or can severely damage it. The first responder has to secure the area, assist any victim if any, arrest the suspects if any, detain all witnesses, protect the crime scene and provide information about all the movements or alteration made to the crime scene investigators or their supervisor.
Knowing this information can help the detectives see the ‘signature’ of the crime, or it can help identify whether they are dealing with a repeat offender. Once the forensic scientists figure out the type of weapon used, they can then begin to find the point of origin.

The body’s position can tell detectives whether it was a surprise attack or the victim knew the person who committed the crime. Another way to find the story is with voids.
Forensic biology is necessary in the current case as it is principal in the identification of both the remains and possibly the perpetrators. A proper identification cannot be achieved if a DNA profiling is not conducted on the remains (Butler & Hill, 2012). The first step in investigating the crime is to secure the crime scene. Securing the crime scene assists in reducing interference of physical evidence and reduces the chances of contamination to the crime scene. After securing the crime scene the next step is to conduct a preliminary survey of the area to establish the presence of any other evidence around the crime scene.
They are the initial result in clearing out most crimes, why? Since they are the first to arrive at the crime scene, the officer’s conduct a preliminary investigation. This includes “in determining whether the offender is at the crime scene or in the area, responding to the victim’s needs, and ensuring the general safety of anyone in the immediate vicinity” (Grant and Terry). The initial crime scene processing and the recordings of relevant evidence and information are critical for a patrol officer to document, since the report will pass on to the detectives/investigators (Grant and Terry).

Scene of Crime Officer- They have a responsibility to protect the crime scene from the evidence being ruined in any way. Their role is to follow correct procedures to collect the evidence- they have to document it by using a camera to take photos of the evidence before they can collect it. Samples are bagged in protective packaging, Evidence that have to be casted such as tire tracks and footprints is done under the same procedure- photographed and then make casings. Forensic Pathologist- They have a responsibility to perform an autopsy and determine a cause of death. Their role is to identify the victim and then find out the time of death of the victim and should be done sooner rather than later to get a more accurate result.
Sometimes, their evidence might be faulty, incorrect, or not strong enough, so they will need other sources to strengthen their illustration. The evidence is carefully examined using different science techniques, depending on the type of evidence (faces, fingerprints, DNA, etc.). So, evidence must be concrete, and there cannot be any holes in their case. They can reinforce their proof by calling up witnesses, alibis, and suspects. Witnesses are people who saw the crime or accident take place.
After reading this paper you should be able to know step by step how to keep notes, take accurate photos and a variety of other things that will allow you to conduct a successful investigation. When arriving to the scene you would want to approach slowly. This is for safety reasons as simple as the suspect might still be in the area and it can cause you to be in great danger. You would also want to ask yourself “what crime was committed here?” and a couple of similar questions in that aspect. However, when you do
