Crime Scene Investigating and Processing Throughout the course of this paper I am going to talk about crime scene investigating, as well as, crime scene processing. I will talk about what a crime scene is what makes it a crime scene. That happens at a crime scene, also, what to look for at a crime scene. I will talk about who is involved in processing a crime scene and when or if other jurisdictions need to be brought in. The first thing that happens when there is a crime being reported is the police are notified by the dispatcher.
First responders play a crucial role in the establishment of a crime scene. Upon arriving at the scene, the first responders have checked for living victims and have rendered aid. It’s important to create a perimeter around the crime scene (this can be altered if additional evidence is found outside the initial crime scene). Only emergency personnel should enter and exit from the central entry point to control contamination, by creating an exit point; it helps avoid any excessive traffic through the crime scene. By secure the scene to ensure that no evidence is misplaced or damaged, or otherwise compromised.
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.
When the call comes in that a crime has been committed, the police are dispatched to the crime scene. When the police arrive on scene, they need to take control by apprehending any suspects and looking for witnesses/victims. If the scene is not safe, the first responders must secure the area. If anyone is hurt, they should call for medical personnel as soon as possible. The first police officer on scene is usually in charge until a criminal investigator arrives on scene.
Role of the Criminal Investigator A criminal investigator is a law enforcement professional who attempts to solve crimes, identify and detain suspects and prevent further crime activities. This writing assignment will include the role of a criminal investigator, the process of investigation, gathering and interpreting evidence, interviewing witnesses, interrogating suspects and the court application of Miranda. The role of a criminal investigator when first arriving on the scene is to meet with the lead detective and first officer on the scene. The criminal investigator will hold a small interview session to collect information that will help them understand what happened, when it happened and the sequence of events that occurred. Once the scene is secured with an sufficient number of officers for the criminal investigators protection and unauthorized personnel are kept out of the crime scene, the crime scene investigator can begin working on the scene.
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.
Once the first officer arrives at the scene he needs to follow these steps if he didn’t catch the suspect red-handed. 1. The officer needs to make sure he can get as much information as he can from the witness if there is one at the scene. Information like, make and model of vehicle used in the crime, a description of the suspect, and what direction the suspect fled from the scene needs to be reported to the patrol force. 2.
When an investigator of an incident scene is looking for testimonial evidence, the investigator is seeking eyewitnesses of the incident. When the investigator is seeking physical evidence, the investigator seeks items that would be present at the crime scene. Physical or testimonial evidence collected at a scene may be used to prove whether or not a crime actually occurred, tie a person to the scene or to a victim, determine key elements of the incident or crime scene, possibly identify the victim or a suspect or group of suspects, uncover physical evidence that corroborates the testimony of an eyewitness, or identify evidence that clears people and shows they were not involved. When processing a crime scene, there are a series of steps that must be followed for this evidence to be uncovered, and for any recovered evidence to remain untainted, and admissible later in court if needed (Newman, 2007). The very first step to an investigation is securing the crime scene.
If the suspect(s) are not located, the responding officers will preserve the scene and any evidence which may have been left behind. This will make the residence safe for investigators to be in the area, and allow them to collect evidence. Now that the crime has been detected and perpetrators have been cleared from the area, officers can move on to the next objective of locating, recording, and processing evidence while observing all constitutional consideratio... ... middle of paper ... ...n of legally obtained evidence and statements. Each and every person involved in the process of the evidence collection and processing must be available for trial. If one of these parties is not available, it may cause some doubt in the juror’s mind, as to what was done with that piece of evidence.
The additional crime scenes may include where the body was moved from, where the actual assault leading to the murder took place, where any physical or trace evidence connected with the crime was discovered, this could possibly include body parts, and lastly if there was a vehicle used to transport the body to and where it is eventually found. There are still other areas that could be related to the primary crime scene. These areas could include the point of forced entry, the route of escape, the suspect clothing, hands, body, and the suspect's residence. “It is important that responding police officers be aware of this multiple crime scene possibility. Therefore, during the initial receipt of information by the police concerning a possible homicide, the officer should attempt to ascertain the exact location of the situation requiring police investigation and possible additional locations that may need coverage.” (The Homicide Crime
