Crime Scene Investigations by First Responders
Crime Scene Investigations by First Responders
Crime scenes contain the forensic evidence required to apprehend criminals. The proper collection and processing of physical evidence is of primary importance to most police investigations. Evidence can not only establish the fact of the offense and identify the perpetrator; it may even lead to a conviction. In collecting this evidence we must be conscious of the public’s Fourth Amendment rights and not violate them in this collection of evidence. Unfortunately, poorly conducted crime scene investigations can sometimes either destroy evidence or render it useless.
Law Enforcement should approach the crime scene investigation as if it will be their only opportunity to preserve and recover these physical clues. They should consider other case information or statements from witnesses or suspects carefully in their objective assessment of the scene. Investigations may change course a number of times during such an inquiry and physical clues, initially thought irrelevant, may become crucial to a successful resolution of the case.
The primary responsibilities of the first responders to a crime include the following: (1) to preserve life. If there is any chance that the victim(s) are still alive it is the first responders’ reasonability to render aid to save said life. (2) First responders are to control suspects and witnesses keeping them both close but separate. Once these two objectives have been achieved, the first responders should focus their attention on protecting and preserving the crime scene. The first response to an incident shall be expeditious and methodical. Upon arrival, the officer(s) shall assess the scene and treat the incident as a crime scene. The first responders should note or log dispatch information such as names, address, time, type of call, and any other relevant information. Be aware of any persons or vehicles leaving the crime scene. The importance of preserving the scene and its adjacent areas

    Homicide is the killing of one human being by another. (Osterburg, J. 2014). Robbery is the act of robbing a person or place. (Osterburg, J. 2014). The crime scene assessment provides the major opportunity to locate physical evidence. The initial response should be regarded as the only chance to recognize, record, and collect physical evidence. The investigator must make the most of it. This search, however, must be conducted properly and lawfully, or the evidence will be suppressed in the course of a trial. Police should not relinquish control over the scene and its environs until all evidence has been discovered, documented and collected. If it must be gone over again later, legal difficulties may be created because…

    The next step is for the investigator to take notes of the crime scene. The process of note taking should be extensive, containing even notes they may seem insignificant but may become valuable evidence later (Fisher & Fisher, 2012). At this point evidence should not be moved or touched. Next pictures are taken at the crime just as it happened. The pictures should include scales to show accuracy in the evidence produced. Next is sketching the areas where the evidence was found is a way to support the picture evidence at court. The sketches should be accurate and contain measurements of the scene.…

    These include photography, drawings, note taking, and videography. Ideally, all of the techniques would be used at each crime scene. Photographs are an important record of the unaltered crime scene. Before any objects are moved from the crime scene or to a different spot, they are photographed. The notes may include a description of the crime scene, the location of pieces of evidence, and how the evidence was discovered. The notes taken should be as thorough as possible as they may have to refresh the memory of investigators before a trial or in other circumstances months or even years after the fact. In addition, the sketches should contain information such as a case identifier, the date and time, a key to identify the objects in the sketch, the orientation of the scene, and other relevant information like the weather or lighting. The recording can be useful to document the overall scene and the relation of elements to each other.…

    They must also confiscate any controlled substances (drugs) seized in violation of the law. They need to collect any devices at a crime scene containing explosive charge and any residue from explosion for suspected explosion charges. Fibers are another form of physical evidence. Investigators have to determine whether fibers are natural or synthetic. The transfer of fibers may be helpful in establishing the relationships between objects and people within a case. They must also establish the identity and place at the scene where there are fingerprints. Firearms, projectiles, and cartridges are another type of physical evidence. Criminalistics investigators have to identify and compare them to other exemplars and firearms. They have to tell whether firearm residue was present and if so approximately what distance and angle was the bullet coming from. In some cases there is glass involved in a crime scene. They need to examine glass particles, window panes with holes, and broken windows to determine the transfer evidence, sequence and origin, and characteristics. The criminalistics unit is composed of different departments…

    The search of the crime scene is the most important phase of any investigation. Decisions of the courts restricting admissibility of testimonial evidence have significantly increased the value of physical evidence in homicide investigations. Therefore, law enforcement personnel involved in the crime scene search must arrange for the proper and effective collection of evidence at the scene.The arguments the lawyer’s will make in the William’s case is: once an item is recognized as evidence it must be properly collected and preserved for laboratory examination. However, in order for physical evidence to be admissible, it must have been legally obtained. The courts have severely restricted the right of the police to search certain homicide crime scenes without a search warrant, (Mincey v. Arizona 437 US 385, 1978).…

    A crime scene investigator has a very important job when it comes to a crime scene. Now the purpose of a crime scene investigator is not just limited to homicides, sexual assaults, armed robberies, home invasions and property crimes such as burglaries (feinc.net. n.d.). However, most of their time is spent processing crime scene, packaging as well as transporting evidence and attending and photographing autopsies (feinc.net. n.d.). They also attend briefings and conferences with any police agencies that request their assistance on a case or cases. Therefore, at some agencies a crime scene investigator may work in the officer from Monday through Friday from 8:30 a.m. to 4:30 p.m. but they also have scheduled after- hours standby duties every…
