It will be discussed having the implications of poor packaging and the results which lead to contamination of all evidence if not packaged properly and the outcome when it is taken to court also the reliability of the CSI’s involved. It is also the job of the CSI to make sure all health and safety procedures are in place before handling and taking any piece of evidence as there are varying risks involved like sharps, contamination of evidence, weather conditions other witnesses interfering with the scene, other personnel and any form of biological hazards. These must be taken seriously and analysed before any search. Unit 5 1. Detail the forensic evidence that would have been taken away from the scene by the perpetrator. The crime scene is probably the most important part of any criminal investigation. It is where forensic science starts. Locard’s Principle states that every contact leaves a trace (Locard, 1928). This is the primary rule of scene investigation – you are looking for ‘contact’ evidence that will help solve the crime. This trace may be in the form of a specific recoverable...

... The topic I am writing about is Crime Scene Reconstruction. Crime Scene Reconstruction is the use of scientific methods, physical evidence, deductive reasoning and their interrelationships to gain explicit knowledge of the series of events that surround the commission of a crime. Crime Scene Reconstruction looks at the physical evidence and attempts to determine “What Happened? And how did it happen?” The reason why I have selected this topic is because I find it intriguing how physical evidence is broken down, evaluated, and reconstructed to actual tell how a crime occurred and what happened in the process. There are many television shows I watch daily that portray the crime scene investigation process in a certain light this is another reason why I chose this topic. I’d like to find out firsthand what actually goes on in the reconstruction process versus fictional exploitations of it on television. Crime Scene Reconstruction looks at the physical evidence and attempts to determine “What Happened? And how did it happen?” A similar method that is used is Criminal Profiling. Criminal Profiling is the application of psychological theory to the analysis and reconstruction of the forensic evidence that relates to an offender’s crime scenes, victims and behaviours. Crime Scene Reconstruction is the use of scientific methods, physical evidence, deductive reasoning and their interrelationships to gain explicit knowledge of the series of events that surround the commission of...

The investigation in the Madrid bombings with the fingerprint evidence was based off of ineffective practices. The fingerprint examiner that led them to a match in Portland, Oregon believed it to be a man names Brandon Mayfield. In addition four other examiners agreed that he was the criminal. However, before he could stand before the judge, the spanish police using video surveillance identified the correct person. 2. What assumptions have been made about fingerprints? What are the problems with these assumptions? Fingerprint identification is suppose to be “infallible”. Examiners are taught that there is no two people that have the same fingerprints....

...PHYSICAL EVIDENCE Name Institution Physical Evidence In the field of crime and justice, the success of an investigation depends on the assemblage and analysis of the different types of evidence (Swanson Et Al., 2012). Forensic experts usually classify evidence ass either physical or biological evidence. Biological evidence refers to any type of evidence that they draw from a living being while Physical evidence refers to any type of evidence that they draw from a non-living organism. Examples of physical evidence are fibers, fingerprints, footprints, building materials and paints among others. On the other hand, DNA and bloodstains are some of the examples of biological evidence (Swanson Et Al., 2012). To me, the most interesting type of physical evidence is fingerprints. Fingerprints are one of the few things that one is sure not denying that it belongs to him or her. By default, everybody has his or her own unique fingerprint (Swanson Et Al., 2012). Therefore, in the case of crime, collection and analysis of evidence becomes easier for the forensic experts in case they get the fingerprints of the suspect. Unlike the other types of Physical Evidence where the suspect can easily deny to having any association with, fingerprints are unique to him or her thus no chance of denying. In fact, if the forensic experts can be able to get the fingerprints at the scene of a crime as evidence then compare it with the fingerprints of the suspect, then the case is as good as done...

...Name Instructor Course Date The Chain of Evidence The chain of evidence refers the paper trail showing the seizure, custody, control, transfer, analysis and disposition of physical or electronic evidence. Any evidence obtained in the course of an investigation is subject to interrogation in a court of law. Subject to this demand, it is important that evidence is kept free from contamination, and achieved through as routine called the chain of custody. A motion of suppression is made by the defendant and is done whenever there is a break in the chain of evidence to exclude the admission of said evidence at the trial. The chain of custody, therefore, ensures the integrity of all material proof of a crime through handling it in a secure and validated manner so that it arrives at court untainted. William is a banker at a downtown bank accused of murder in the first degree. William took part in a protracted argument with Miles, a mechanic, at a local restaurant that ended with Miles assaulting him. William is suspected to have driven over to Miles house later that evening, cornering him in the kitchen, and shot him twice in the chest with a revolver.The much larger Miles was able to wrest the gun out of William’s hands. A short struggle ensued, which resulted in William stabbing Miles in the neck with a kitchen knife. Alarmed neighbors called the police at the sound of the shots being fired, and the first patrol car arrived on the scene three minutes later and found Miles dead...

...Introduction Trace evidence has always played a role in criminal prosecutions. However, it was always been in the manner of supporting other evidence. The Wayne Williams trial changed the course of history, as it would be the first to use fiber evidence as its primary means of securing a conviction (Deadman, n.d.). Wayne Williams was suspected of killing 28-30 young boys and men in the Atlanta area, over the course of two years. Although the cause of death was similar among the victims, police had little to no other evidence to follow up on except a yellowish/green fiber with violet accents, found on twelve of the victims (Owens, 2009). Fiber experts in the Washington D.C. Federal Bureau of Investigation, (F.B.I.) lab analyzed and concluded that the fibers on all the males were “a match”. It was determined that the structure and color of the fibers was very unique. The design was that of a triple lobed, cross sectional pattern, similar to that used in...

...is one that is a vital part of the criminal investigations process which has contributions from many areas of this component. In this case study there will be points expressed on the crime scene search, principles, crime scene photography, sketching the crime scene, fingerprint evidence, trace evidence, and biological evidence. Investigators have the responsibility to comprehend these segments in order to effectively manage and maintain a crime scene. The crime scene investigation consists of elements of criminal law, criminal procedure, and constitutional evidence. The search part of the crime scene involves a related focus which is in legal requirements. It is crucial to incorporate the Fourth Amendment in the crime scene search process which implicates the search and seizure warrant rule. Many investigators and officers are unaware of the absence of generally recognized exceptions to the search and seizure warrant rule, law enforcement officers must obtain a warrant to search a crime scene where a reasonable expectation of privacy exists. (Geberth, 2003). The procedures behind crime scene searches consist of isolating, securing, search, and document the scene, as well as obtaining physical evidence which is the physical objects linked to the order of a crime such as hairs, paint chips, fibers, and bullets. Records which are basically keeping accumulated general descriptive data of the crime scene, and witnesses. In isolating and securing the crime scene an investigator should...

...Week 2 Thought Paper CJE4610 8/31/14 A case starts the moment the call is received. In many cases there is evidence or clues on the call itself. One of the things you can get from the call is a description of the incident, suspect information, and other various clues and information. Then when you get on scene your real investigation will begin. You may or may not have real life suspects or victims on scene. Once you get on scene you have to start processing information and the scene itself. You never know what clues you will get when you show up on scene. There are different types of evidence to collect when you process a scene. There is trace evidence, which includes hairs, fibers, glass and soil. The second is impression evidence, which includes fingerprints left on objects, and also palms, tires and cloth. The next kind of evidence is biological to include blood, teeth and skeletal remains. The fourth kind of evidence is firearms and weapons including the guns and ammunition. The last is probably the one that most people forget or disregard, are documents to include contracts, currency, passports, and other documents. In the case that was presented on page 126 there was a lot of evidence to be processed. The call originated as a disturbance from neighbors. The officers arrived and discovered a very disrupted house. From the pictures, there were obvious signs of a struggle with in the residence. So the description stated that when the officer arrived no one...

...Dayani Herrera * Week 2 Assignment The Chain of Custody Process Limiting Access to the Evidence * When a piece of evidence is collected, there are numerous individuals who will have access to it before the case goes to trial. The investigator, evidence technician, property officer, laboratory technician, prosecutor and defense attorney all may have custody. Each individual in this chain has a responsibility for the safe-keeping and preservation of the evidence while it is in their possession. Initial Collection * Before any evidence is removed from the crime scene, there should be an evidence custodian designated as the person in charge of initiating and maintaining all evidence. This person needs to document the crime scene location, as well as his time of arrival. There should also be a crime scene log established, witness list and documentation of identification, arrival and departure times of all law enforcement crime scene personnel. Record Keeping * The investigator who handles the evidence initially should affix her name, badge number and assignment to the package containing the evidence. When the evidence leaves the officer's possession, a record should be made in her case notes identifying to whom the evidence was given, the date and time, and the reason it was turned over. A signed receipt should be obtained from the person accepting the evidence and another signed receipt should be obtained when the item is returned. When the item is returned...

...Forensic Science is the application of science to the law. In recent years the use of forensic science has become increasingly necessary to help with criminal and civil investigations. Although forensic evidence is admissible in court one must keep in mind how that evidence made its way to the court system. I will take you through the process. For there to be admissible evidence for a court case there must be physical evidence which would have been collected at a crime scene therefore there must have been some kind of crime committed. A crime with physical evidence doesn’t necessarily mean something violent but it can be. Theft, arson, car accident and murder are just a few examples of what a crime can be. The process begins when the crime has been committed, to the officers arriving on the scene, to surveying the scene, collecting the evidence, submitting it to the lab, submitting it as evidence and finally the acceptance of the evidence. When a call is sent out regarding a possible crime and the first officer arrives on scene it is that officer’s obligation to do a few things as precise as possible: 1. seek medical attention for those who may need it, 2. arrest or detain any perpetrators, and 3. secure the crime scene. Securing the crime scene is extremely important because you want to be able to retrieve as much evidence as possible. By securing the crime scene you are blocking off the area from unauthorized personnel. You want to keep the foot traffic to...
