Comparing simple techniques simply to retrieve a piece of evidence is completely different as we learn more about the science and learn from the mistakes made in the past. Looking back at the 1800’s and comparing the technology of the 21st century, the difference is certainly huge. The increase in technology makes information more vast and more ideas can be shared easily. Many sciences are based off many “what ifs” while forensic science is more factual and attempt to solve puzzling occurrences and events and get down to what truly
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.
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”
It is a fact that there are approximately 16,238 murders a year. That is 44 murders a day. Not to mention 14.7% of these murders are committed by females. It can be inferred that Lizzie Borden committed these crimes due to the items found at the crime, all of the evidence points to Lizzie, and the fact that Lizzie and Emma Borden may have wanted some of their father’s money.
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.
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.
● It can be used to determine if a person is guilty or not. The evidence from forensic can be enough to put a person into prison. ● It can be used to solve old unsolved cases if there is still DNA available from that case. ● Help identify victims in big disasters where the body of the person can not physically be easily
The physical evidences are gathered at any crime scene, for example, hair, fibre, blood, fingerprints, footwear, bare-footprints, tire impressions and any fracture
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
DNA in Forensic Science DNA is the carrier of genetic information in humans and other living organisms. It has become a very useful tool in forensic science since it was discovered. In forensic science, DNA testing is used to compare the genetic structure of two individuals to establish whether there is a genetic relationship between them. One example of the use of DNA in forensic science that is important in biology today is comparing a suspect’s DNA profile to DNA that was discovered at a crime scene.
As a digital forensic investigator, I was assigned to a case where my expertise where needed. My role in the investigation was to search the suspects digital evidence to help find more helpful information and advance the case. Overall my job as a digital forensic investigator was to recover and analyse the digital evidence so that it could be used in the criminal prosecution. Approach to Case My method of investigating a case was using a systematic approach as this is the accepted procedure to follow.

DNA in forensic science The majority of cells making up the human body are diploid cells carrying identical DNA, with the exception of haploid gametes and red blood cells. Several types of biological evidence such as blood and hair are commonly used in forensic science, which is the scientific study of evidence for crime scene investigations and other legal matters. Forensic science is used for the purpose of DNA analysis, this is the analysis of DNA samples to determine if it came from a particular individual. DNA analysis is done by obtaining DNA samples from an individual; next, a large sample of DNA is produced from amplified selected sequences from the DNA collected.
INTRODUCTION This project deals with the procedure followed in ballistics section of forensic science lab where cases duly reported in which firearms are involved. Some of these cases will be studied in detail also their lab examination. Before entering into the topic it is important to picture a brief idea about what is ballistics and what is a firearm. Ballistics is a science specifically mechanics that deals with the launching, motion and behavior of a projectile both in air and on the target as well as effect due to the launched projectile on the target.
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.
