- 2. Good morning everyone, my name is Kevin Irizarry Marrero and today I will talk to you about Forensic Science and what it is in general. I will start with an introductory video on Forensic Science. • https://www.youtube.com/watch?v=_58XsN6XJWQ What is Forensic Science? Forensic Science means any science which is used as evidence in a court of law. It is also taken to mean scientific analysis and comparison used in the detection and investigation of crime. The word forensic is derived from the Latin adjective forensis meaning "of or before the forum". In ancient Roman society, cases involving criminal charges were presented before a group of individuals in the forum. Both the victim and suspect would give speeches on their side of the story. The best argument would determine the outcome of the case. Towards the end of the 19th century, the acceptance that everybody has different fingerprints made a great impression on the detection of crime, as did the discovery that people have different blood groups, so that blood stains left at a scene or found on an injured party could be linked to a suspect. Forensic Science has been greatly popularized by authors such as Sir Arthur Conan Doyle, through his infamous character Sherlock Holmes, and through many contemporary TV series such as CSI, Dexter and Bones. It has also created unrealistic expectations from forensic science known now as the "CSI Effect". Forensic science helps law enforcement officials solve crimes through the collection, preservation and analysis of evidence. For example, if there are no witnesses to a crime, forensic proof is often all prosecutors have to investigate. If human remains have decayed so much that they can no longer be identified, forensic experts study dental work, DNA and skeletal structure to identify a person and determine gender. In most cases, forensic investigators can ascertain the reason for death and whether crime was involved. Forensic science is used most frequently with sex crimes and crimes related to drugs. Forensic toxicology establishes if an individual was intoxicated or high while driving after a deadly mishap or if somebody was poisoned to death. DNA proof retrieved from a victim’s body can also ascertain who was accountable for physical or sexual violence.

Forensic experts utilize their expertise in ammunition to analyze the impact of a bullet, determine the number of shots fired and pinpoint the exact position of a shooter. Specialized staff is needed to conduct forensic investigations, such as Crime scene investigators and other forensic scientists. What is a Crime Scene Investigator? A crime scene investigator is, more often than not, a member of law enforcement who is responsible for identifying, collecting, preserving, and packaging physical evidence at the scene of a crime. Although it is often believed that crime scene investigators are the professionals performing tests on the physical evidence, those jobs, in fact, are reserved for forensic scientists and other forensic professionals. A select few crime scene investigators may also perform laboratory forensic work, although the majority of crime scene investigators perform their work at a crime scene, where they collect everything from firearms and fingerprints to DNA samples and photographic evidence. A crime scene investigator is a rather broad title, as this professional may be a: Crime scene leader, Crime scene technician, Forensic photographer, Forensic sketch artist, Ballistics expert, Fingerprint expert or a DNA expert A crime scene investigator is most often employed by a local, state or federal law enforcement agency. These professionals may be employed by a town’s sheriff’s office, by the FBI, or by a state police department. What is a Forensic Scientist? Although forensic science may be a very complex study, particularly in the areas of DNA and trace evidence, for example, the study of forensic science is grounded in fundamental concepts and techniques that are gathered from the natural sciences. In particular, the study of forensic science involves a multi-disciplinary approach that covers everything from biological methods to analytical chemistry techniques. Forensic scientists may be divided into three, major groups: •Forensic Pathologists: These include medical examiners and other professionals who oversee autopsies and clinical forensic examinations.
- 4. •Forensic Scientists: These include forensic professionals working in law enforcement, government, or private forensic laboratories who are responsible for dealing with any number of specific tests and analyses, such as toxicology, ballistics, trace evidence, etc. •Associated Scientists: These include scientific professionals lending their knowledge to forensic science, such as forensic odontologists, forensic botanists, forensic anthropologists, etc. These scientists apply their knowledge to the forensic science field as to provide investigators with crucial information regarding everything from bite marks to insect infestation on the postmortem body. The importance of Forensic Science. Forensic science is very important because it aids in establishing the guilt or innocence of potential suspects. Forensic evidence is also useful for linking crimes, which establishes the patterns of crimes and also narrows the number of probable suspects. My personal Input. We shouldn’t forget that the idea of a complex, hard to avoid, crime prosecution system really helps in the demoralizing of criminal intent and the fact that constant technological advancement, particularly in forensics can lead to solving cases that were impossible to solve in the past. This was basically general information on what Forensic Science is. Thank you all for your attention.
