Forensic Science

CSI and forensics have recently been very popular, leading to shows and books focusing on this interesting detective work. Forensic science is the use of science in the field of criminal law. Forensic scientists have different jobs, such as investigating, running test, and analyzing evidence. Most forensic scientists have an undergraduate degree in a scientific or mathematical field. There are different fields and categories in which these scientists perform their tests and studies. But no matter which field of forensics you do, all forensic scientists have one thing in common; they use science to solve their cases. These scientists solve crimes by analyzing physical evidence found at the crime scene. Forensic scientists decipher crimes using

There are different fields in forensics, and you’ll need a degree in a scientific or mathematic subject. To be more specific, you’ll need at least an undergraduate degree in math, chemistry, biology, and physics, to name a few. The three main fields of forensic science are field science, laboratory science, and medical science. First, field scientists collect evidence, prevent the contamination of evidence, and provide theories as to what they think happened. When collecting evidence, the field scientist must be very careful and aware of their surroundings. They usually wear plastic suits and gloves so that their fingerprints, hair, saliva, and DNA do not contaminate the evidence. However, if it does become contaminated, the scientist is at risk of ruining a piece of evidence that might have been very useful. While looking at the crime scene, they may also suggest theories that might be possible. Next, laboratory scientists analyze physical evidence, DNA samples, and ballistics (the study of the motion of projectiles like bullets). Laboratory scientists do most of the analyzing. One of their jobs is to find DNA samples and test evidence for clues leading to their perpetrator. The analyzation of fingerprints, writing, drugs and more depends on them. They study ballistics, and they find out the weapon type, the distance from the gun to the target, and the angle in which it was fired. Lastly,

While on the scene, the field scientists will most likely create theories to give them a good idea of what may have happened. They will come up with multiple theories because, in reality, they don’t know what really happened. Sometimes their first theory is correct, but other times, none of their theories make sense. Once the theories have been determined, they will try to prove them using evidence that has been collected. Sometimes, their evidence might be faulty, incorrect, or not strong enough, so they will need other sources to strengthen their illustration. The evidence is carefully examined using different science techniques, depending on the type of evidence (faces, fingerprints, DNA, etc.). So, evidence must be concrete, and there cannot be any holes in their case. They can reinforce their proof by calling up witnesses, alibis, and suspects. Witnesses are people who saw the crime or accident take place. Alibis are people or evidence that prove that someone was not at the scene of the crime and that they are not involved in the way you think they are, or at all. Lastly, a suspect is a person who is believed to be guilty of a crime. These people can help prove a theory brought on by a scientist. They can tell what they saw, how everything went down, and who was there at the time of the accident. But to really prove their case, the forensic scientist needs to be very accurate, detailed, and unbiased. They
