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.
As shown throughout the text, the author explains that forensic science can help narrow down suspects by providing
Fingerprinting a suspect in a murder case can have a positive affect on many cases and in this case it did. During the murder trial there were a lot of speculation out there about who killed
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.
Every day forensic investigators use tactics just like the ones that were discussed throughout the paper. It’s more than just looking for an admission of guilt, and interrogating potential suspects until they
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.
This exclaims that without these firm and vital procedures the guilty may go free, or the innocent may be wrongly convicted. People who believe that forensic science is irrelevant and untrustworthy are out of their
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 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
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.
The Department of Justice says, "States began passing laws requiring offenders convicted of certain offenses to provide DNA samples. " That DNA evidence can help convict someone of a crime and it helps to uncover more things about the crime itself. Investigators have been using forensic science to help them solve cases since before the 90 's, mostly fingerprints that were found at the crime scenes and on the victims (O 'Brien). DNA evidence has solved countless cases including ones that happened over a prolonged period of time because of the technological advancements there is
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”
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.
My thoughts Forensic science is used everywhere. It can be used to arrest and convict someone of a crime. Before watching The Real CSI video, I thought using fingerprints and DNA will get you 100% accurate results. Throughout the video my thoughts about the subject began to change.
The educational path required to achieve my goal of becoming a forensic scientist will be a long, exhausting process. The different characteristics of forensic science- like the use of analytical techniques- is what sets itself apart from just any other science degree(Thorpe). Being just a junior in high school, KEES money plays a major role in helping me decide where I go
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.
