Anywhere anyone goes, they leave evidence on everything. Evidence includes leaving your fingerprints, footsteps, bloodstains, or body fluids. In the article, “Forensic Science: Evidence,Clues, and Investigation”, by Andrea Campbell, she explains the way forensic science is able to contribute to a large and important role in solving crime scenes and criminal cases today. The author has shown that forensic science is unquestionably the most important evidence to present at trial. Throughout the text, the author shows how forensic science and evidence is used in court trials and in criminal cases to answer legal questions. One example of how she explains forensic science is used is by mentioning how the evidence can draw together knowledge from multiple different fields. In the text, “Forensic Science: Evidence,Clues, and Investigation”,by Andrea Campbell, she states, “It draws together principles and knowledge from one field, or combination of fields – such as medicine, mathematics, physics, chemistry,biology, and anthropology – and applies them to legal proceedings.” This evidence from the text explains how forensic science can be used to answer legal questions. …show more content…
The author explains this by showing the reader how forensic science can offer assistance to solving crimes and having better evidence at trial. In the text Andrea Campbell mentions, “But forensic evidence, which falls into the fourth category above, often serves as the added weight that helps tip the scales of justice. It may be used to reconstruct the crime, identify participants, or confirm or discredit an alibi.” This display of evidence shows forensic science or evidence of how it can be used in criminal justice and to solve criminal
Evidence is vital for any crime scene. No matter the case, police need to be carefully precise, speedy, and methodical to be able to collect this crucial evidence. With the very well handled cases out there, some slip through the cracks. Evidence that is linked to a crime can be contaminated, destroyed, or forgotten about which leads to finding a suspect to be hard. One example of this happening is the infamous murder case of JonBenet Ramsey.
In this paper I will be comparing contrasting two various aspects of forensic sciences used, and talking about the different tactics used to identify suspects; as well as the contrasts between the two methods. The man I will be talking about is John Wayne Gacy. The two methods I will be going over are, Finger print DNA and Forensic toxicology. These two are very similar, but made substantial differences in the evidence in his case. John Wayne Gacy was a murderer from Chicago, Illinois.
A major crime scene, such as JonBenet’s, details where serious physical and/or emotional trauma is reported, this can include crimes such as murder, manslaughter, and rape (Standing Bear 1999). Due to the nature of a homicide, evidentiary findings can only be determined after a professional examination of the crime scene has occurred (Pepper 2010). The three principles to ensure an effective investigation is conducted includes: rapid response to the crime scene; to secure the scene before evidence is contaminated, damaged, lost or stolen. Secondly, gathering of evidence, all evidence at the crime scene must be preserved and noted whether physical or testimonial; in some cases, this can lead investigators straight to the perpetrator. Lastly, processing of the evidence; this includes putting together all available evidence to determine a verdict in court (Pepper 2010).
This paper is to serve as an in depth analysis of all aspects of the physical evidence found at the scene, and later at O.J.’s house. The origin of the evidence, relation to the crime scene, connection to O.J., and the legalities of the collection and handling of said evidence will all be examined. A sample of blood was discovered on a pair of O.J. Simpson's socks that were found in his bedroom; after a DNA analysis was conducted, the blood was identified it as Nicole Brown's. Although this seems like substantial evidence, the handling of the evidence comes into
First off, the main and most commonly known use of forensic anthropology is to catch criminals and protect the living. It can be referred to as giving a voice to those who cannot speak- the dead. As stated in the documentary Secrets of the Body Farm, forensic anthropology was originally
There is powerful verification that fingerprints aren’t foolproof. In “ Forensic Science: Evidence, Clues, and Investigation” by Andrea Campbell, she gives a strong explanation of how forensic science plays a vital role in solving criminal cases. Campbell has shown that forensic evidence is unquestionably the most dominant type of evidence to present at a trial. In the same way, “...unless the criminals take something away from the crime scene, hard evidence does not leave.
Forensic Science is evidence that typically comes from sources like fingerprints, bodily fluids, and bullets. In “Forensic Science: Evidence, Clues, and Investigation” written by Andrea Campbell, she explains how forensic science can make or break a criminal case. Campbell has given readers many reasons to believe that forensic science is without a doubt an important piece of evidence to present at trial. Some reasons Andrea Campbell explains are that it can help narrow down suspects in order to find the criminal responsible for a crime, and that it can provide physical evidence that can provide further information about a case.
In many cases, post-conviction DNA testing has revealed that the DNA found at the crime scene did not match the DNA of the individual who was convicted. We use DNA to link crimes, DNA evidence can link crimes that were previously thought to be unrelated by identifying the same perpetrator through matching DNA profiles found at multiple crime scenes. Like we identify suspects we can also Identify victims, DNA evidence can be used to identify victims of crimes, such as in cases where the victim's body has been severely damaged or decomposed. Providing evidence in court DNA evidence is admissible as evidence in court and can be presented to a jury to help establish the guilt or innocence of a defendant. DNA evidence has become an important tool in the criminal justice system and has helped to solve many crimes, as well as prevent the conviction of innocent individuals and try so hard to find out who the offenders
Forensic science has contributed to wrongful convictions and the correction of wrongful conviction by bringing to surface the issue of how involved flawed forensics has made an impact. In Gary Dotson case, false claims were made involving the forensics that was used throughout the case, in such cases as blood comparison and analysis of hairs. The correction to the field of forensics associated with allowing wrongful convictions to be overturned because it reveals the flaws in forensics that previous cases used to implement and by demonstrating how certain types of forensics are unreliable and invalid (Garrett, 2011). There are a few cases that the forensics completed mislead the jury because they were not showing the truth but rather flaws.
Forensic science has been an aid to the law enforcement community for years now. It has solved cases that were unsolved years before DNA and science started to play a role with cases and law enforcement. The case of Samuel Reeves and James Layne was unsolved in the year 1989, this was considered a cold case because it had been years since they found who the murderer was. This case was considered a crime of passion, where it first started off by kissing and having the same attraction towards each other, but when James Layne started to get aggressive and not respecting Reeves decision to not have sex, that was when things got hectic. Forensic science helped this case by the use of fingerprints, they found the fingerprints in a bottle, and when
Compelling Evidence In today’s society, high-tech gadgets and the media have given the impression the essential necessity for forensic evidence in order to convict. Once in a while, cases like the Laci Peterson murder come along with little forensic evidence but a whole lot of circumstantial evidence and motive. In the following paragraphs, I will discuss the forensic evidence discovered that led to the conviction and death sentencing of Laci’s husband, Scott Peterson.
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.
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”
This evidence helped them investigate the case to see if it was the same person who has committed this murder and to capture the person and take them into custody. The critical evidence that they used was the blood that they got from the victims' bodies to figure out if it matches the person who has does this murder. It was the first time that they were using DNA to convict the murderer. The blood semen that they got from each of the victims they used that to punish the murder who done these murders.science and the Forensic Science:After a month there was another occurrence were Stephanie had vanished, another lady disappeared. A seeker found a gravely decayed body of a white female, the remaining parts were scattered by creatures, yet the agents recuperated her skull, middle, and some dress.
