A positive aspect of this is that forensic scientists only need a small amount of a sample to get the results they need (“Forensic Science” 12). These samples can come from many other forms of identification other than fingerprints and bloodstains. A few moderate examples include strands of hair, tiny beads of sweat, and a saliva specimen (“Forensic Science” 12). Forensic Science Technicians stated that “crime scene investigators may use tweezers, black lights, and specialized kits to identify and collect evidence.” They also stated that examining autopsies prove to be beneficial in a crime investigation (“Forensic Science Technicians”
In the forensic investigation, there were 6 pieces of forensic finding used in Timothy McVeigh trial. The first set of the finding was the earplugs that he wore to silent the noise of the explosive. Meanwhile, there was a trace of residue found in his jean pockets along with two t-shirts and a knife with the sheath. Therefore, due to the positive mixture founded on McVeigh, the prosecutor believe that McVeigh was involved in making a bomb from a mixture of ammonium nitrate and fuel oil. It was believed after, Timothy McVeigh also participated in placing the barrel of bomb ingredients in the back of the rental Ryder truck.
Despite the television show's portrayal of trace evidence and other physical evidence being left behind at every crime scene, this is not the case in every criminal investigation. In fact, many criminal investigations yield no evidence that can be forensically tested. This means the investigator must gather information from the crime scene such as witness statements, victim statements, possible suspects including those who are seen fleeing, as well as any physical evidence. The investigator must also follow any leads gathered from victim and witness statements. While in CSI the investigator always catches the criminal within an hour, a criminal investigation may take days, weeks, months and even years before being solved.
Science has come a long way over the years. It has helped countless every day struggles and cure diseases most commonly found. What you don’t hear about however is the advancement of forensic science. Forensic science has helped solve countless cases of murder, rape, and sexual assault. In the case of John Joubert, it helped solve the murders of three young boys with one small piece of evidence that linked him directly to the crime.
Evidence found at the place of the crime can give investigators clues to who committed the crime. For example, investigators can find footprints, fingerprints, or even the murder weapon. In fact, a hatchet was found on property, which detectives believe is the murder weapon(Allard,2013). This is important because the hatchet gives clues to who committed the crimes.
The detective would analyze the last known pictures of the couple. He would try to determine if the couple in the picture was happy or had conflict. Knowing if the image was unrealistic or manipulated could help solve the case. Having the knowledge to know how we are being manipulated through image is useful. Images can be used to manipulate us to buy an expensive brand of coffee based on the marketing ad.
The relatives of teenager Jaylen Fryberg claim they are currently living in a nightmare as they try to understand why the 14-year-old student went on a shooting rampage at Marysville-Pilchuck High School in Washington, U.S. The police are still reportedly piecing together the motive for the tragic shooting that happened at the school last Friday, Oct. 24, where Jaylen Fryberg targeted his cousins and friends before shooting himself. It has been confirmed by the Snohomish County sheriff’s office that the on-scene crime investigation has been completed with the 0.40 calibre handgun used in the shooting already recovered. Jaylen Fryberg’s relatives confirmed as well that the teenager targeted his two cousins, Nate Hatch and Andrew Fryberg.
Doing this, helpws protect the evidence and prevent cross contamination. The crime scene is the physical area where a crime is thought to of occurred and where the evidence of the said crime is thought to reside. Vital evidence to a case, can be found at a crime scene. This includes, fingerprints, DNA, foot prints, bullets, bullet casings, fibers, etc. It is important to determine if a crime has in fact been committed, if so, the officer must initiate enforcement action, by arresting or pursuing the offender or dispatching apprehension information.
In interrogating of the victim, the officers decided this incident is a single-location crime scene because there is not any multifaceted networking or anything with huge storage capacity. In order to ensure proper protocols in this investigation, the officers call for a trained investigator from their department who has the basic skills to organize the investigation, determine the elements of the crime and the connection between the suspect and the crime, and document the investigation (Taylor, Fritsch, Liederbach, and Holt,
General crime scene documentation is accomplished through a combination of photographs, sketches, and notes (The Fingerprint Sourcebook, 2011). Photographic evidence of the crime scene ensures that the locations of all evidence are visually recorded for use in a court case. Any questions on the position of items can be answered by looking at the crime scene photographs. My notes would include where items were found, what position, and condition they were in before being collected or processed for fingerprints. Without photographic evidence of the crime scene and items in their original locations, it may be hard to prove or confirm details in court later on.
R.U. Steinberg says, “After that area we top it off with perimortem [time of death] pathology. That, of course, is of primary interest to law enforcement, because they use that to determine if a murder has occurred. We look at the fine details of bones; little tiny nicks or scratches can be knife cuts or nicks from a bullet”(R.U. Steinberg, 3). This shows how important it is to find the cause of death because it is very helpful to police and bringing the killer to justice. It also shows how much information you can find from just looking at one
Crime Scene Reconstruction (CSR) Case Studies Proving Murder Case 1 A man shot his father using a pistol. The bullet grazed the left forearm and the entry wound was on the left side of the abdomen; there was no exit wound as the bullet was obstructed by the right pelvic bone. The man claimed that the shot was accidental and due to falling when his father pushed him. A three-dimensional (3D) reconstruction was necessary to identify whether the case was intentional or not. CSR of Case 1
Crime scene photography, sometimes referred to as forensic photography or forensic imaging, is the art of producing an accurate representation of an accident or crime scene. Crime scene photography is an important asset in the collection of evidence at the crime scene, documents the appearance and location of victims, shell casings, footprints, bloodstain patterns, and other physical evidence. In order for photographs to be admissible in a court of law, the standard for photographs of crime scenes and evidence must be of sufficient quality. Photography has a vital role in the decision made in court because the pictures are to represent the scene as it was exactly. Digital SLR single reflex camera is the most often used camera in crime scene investigations.
