The Field Of Forensic Science Requires Specialists In Many Different Disciplines

The role of forensic science in criminal scene investigation is an important tool in the art and science of solving crimes, reaching back at least 100 years. Sherlock Holms, the most admired and recognized name associated with solving crimes, often used creative forensic examination techniques. Many were found guilty based on his analysis of the crime scene evidence accompanied by his astounding powers of deduction.

Using forensic crime scene evidence was not just limited to an author’s fantasy, but began to play an important role by forensic scientists of that era. Some of the earliest success started with matching a bloody fingerprint recovered from the crime scene to a suspect. This use of forensic evidence was convincing enough to obtain convictions in a court of law.

Advances in technology provided methods of gathering evidence, such as fingerprints, from many more areas of the forensic crime scene. Methods were developed that can collect and transfer a fingerprint not visible to the human eye, from numerous surfaces types. With new technology in the form of image enhancement tools and enhancement chemicals, fingerprints can be collected and analyzed to provide the detail that clearly shows a definite match with the perpetrator.

Often the forensic crime scene contains impressions of soft pliable material such as dirt, sand, grass and mud. There are methods that exist today that when used by an experienced forensic science expert will accurately measure the impressions to determine the manufacture and model of shoes and vehicle tires. Often this is the final connection needed to obtain a conviction.

The key to productive interpretation of the crime scene by forensic scientists is for the initial investigators to immediately block off the area until an experienced forensic investigation can begin. Through the use of digital cameras the scene can be recorded to provide details that will support other objects and crime scene arrangement detail that might be foreign to that location. Useful forensic evidence could be objects left behind such as plants, leaves, seeds and even a pattern found from the bent grass and undergrowth.

Modern technology itself can provide forensic data to a highly trained forensic scientist. Many cars contain computers that record useful data that when put together with other known evidence substantiate facts that can lead to conclusive hard evidence. The content of memory devices in cell phones and computers often contain useful evidence that a forensic scientist who specializes in using modern electronic tools for extracting data from the device, even after the files were believed to be erased.

So, there are many interesting specialties available for study and practice by forensic scientists. Forensics offers a very exciting and challenging field with a variety of disciplines from which to choose. Your choices include crime scene analysis, biologist, engineer, toxicologist, computer specialist, psychologist and pathologist, the field most identified with forensics. All of these fields require the study and knowledge for you to be recognized as a specialist in the field such that you could give convincing and compelling expert testimony in a court of criminal justice.
