Forensics is a very complex field. If the crime scene is not secured correctly, or piece of evidence is handle wrong or "contaminated", an entire case can change in favor of the culprit. JonBenet Ramsey case is a prime example of police failing to secure the crime scene and due to that valuable evidence is lost forever. The mysterious death of JonBenet Ramsey (the daughter of a socialite and a wealthy businessman) was a case that could have been solved if the crime scene was correctly secured.
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
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”

They collect and analyze evidence many technicians specialize in either crime scene investigation (CSI) or laboratory analysis. Being a CSI agent offers tons of exciting action with interesting daily tasks, mental challenges, and modest educational requirements compared to most occupations. CSI agents experience many interesting daily tasks, they first walk through the crime scene to determine what evidence is available and collect it. According to Chron, DNA experts use bodily fluids and substances
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.
In a forensic science lab, the criminologist must have access to a variety of chemicals, and compounds; as well as different specialized machinery.
(Greene & Heilbrun, 2014). Applied scientists are in vital in the core components of the American justice system. Applied scientists have a variety of responsibilities throughout the corrections field such as treatment and counseling. An example of an applied scientist within the court system would be an expert witness. An expert witness is an individual that possesses specialized knowledge who can testify regarding this information in court (Mullen, 2010).
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.
“An investigator starts research in a new field with faith, a foggy idea, and a few wild experiments” (Cram). This quote was said by Donald Cram in discussing how an investigator should start an investigation. The job of CSI consists of collecting and analyzing evidence. At a crime scene CSI typically collect evidence, take pictures, make sketches and a variety of other tasks. CSI is a fascinating career choice because one gets to travel, perform a variety of tasks, and gets to investigate and help society by investigating criminals.

The goal of the computer forensics is to provide information about how the crime happened, why and who is involved in the crime in any legal proceeding by using the computer forensic tools.
Forensic anthropology is the branch of anthropology which deals with the recovery of remains as well as the identification of skeletal remains which involve detail knowledge of osteology (skeletal anatomy and biology). In other words, forensic anthropology is the application of anthropological knowledge and techniques in the identification of human remains in medico-legal and humanitarian context. Forensic anthropology includes the identification of skeletal, decomposed or unidentified human remains. Forensic anthropology may also help determine the age, sex, stature and unique features of deceased from their remains. Personal identification is one of the main aspects of medico-legal and criminal investigations.
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.
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.
