At the heart of every forensic science course is Locard's Exchange Principle, which states that "every contact leaves a trace" . This is the fundamental concept that every forensic scientist relies upon—when a perpetrator enters a crime scene, they will both leave something behind and take something with them, whether it's a fingerprint, a hair, soil from their shoes, or fibers from their clothing .
"Every contact leaves a trace"
Statements from victims or witnesses. This type of evidence relies on human memory and perception, which can be fallible.
Tangible items from the scene, such as biological material, fibers, fingerprints, and tool marks. Often considered more reliable than testimonial evidence as it is objective and acts as a "silent witness" to the crime .
The field of forensic science is broad, encompassing numerous specialized disciplines. The U.S. Department of Justice outlines several key areas practiced in its laboratories 5 :
Theory comes to life in the laboratory. Whether in a university setting or a professional crime lab, forensic scientists rely on a suite of standardized experiments to analyze evidence.
Fingerprints are unique patterns formed by ridges on the skin, fully developed before birth, and are a cornerstone of forensic identification 7 . The three primary patterns are loops, whorls, and arches 7 .
This procedure is used to develop and lift fingerprints that are not visible to the naked eye 7 .
Ensure the surface (e.g., the outside of a drinking glass) is clean and dry.
Using a soft-bristled brush, gently sprinkle a small amount of powder. Talcum powder or cornstarch is used on dark surfaces, while cocoa powder is better for light surfaces 7 .
Swipe the brush gently over the powdered area to remove excess powder, leaving the print pattern visible.
Carefully press a piece of clear tape (sticky side down) onto the developed print. Lift the tape smoothly and transfer it to a piece of paper that contrasts with the powder color for preservation and analysis 7 .
After lifting the print, the pattern (loop, whorl, or arch) can be identified. This print can then be compared to known prints from suspects or entered into a database. The uniqueness of each individual's fingerprints makes this one of the most reliable methods for placing a person at a scene.
Chromatography is a method for separating the components of a mixture, widely used to analyze inks, dyes, and drugs 8 . In a forgery case, it can determine if more than one pen was used on a document 7 .
| Material | Function |
|---|---|
| Tall glass or beaker | Holds the solvent (water or alcohol). |
| Filter paper/Paper towel | The medium through which the ink separates. |
| Water, rubbing alcohol, or nail polish remover | The solvent that carries the ink pigments. |
| Various black markers/pens | The samples to be tested and compared. |
| Pencil & ruler | To mark the starting line on the paper. |
Fill the glass about halfway with solvent (water is a good starting point).
Cut strips of filter paper. Use a pencil to draw a line about half an inch from the bottom of each strip.
Make a small, concentrated dot with a black marker on the pencil line. Use a different strip for each pen or marker being tested.
Suspend the strips in the glass so the bottom edge touches the solvent, but the ink dot remains above the solvent level. The solvent will travel up the paper.
As the solvent moves, it will carry the ink with it, separating it into its various colored pigments.
Different ink formulations will separate into unique patterns and colors, creating a distinctive "fingerprint" for each pen. If an unknown ink sample from a questioned document matches the chromatogram of a suspect's pen, it provides strong evidence that the pen was used in the forgery. A key limitation is that the process can destroy the evidence sample 7 .
The field of forensic science is constantly evolving, driven by technological advancements. Recent research highlights exciting new developments 2 :
Scientists are developing chips that can detect a single trillionth of a gram of a molecule using just electricity, promising unprecedented sensitivity in detecting biological traces 2 .
Artificial intelligence is being used to pinpoint the origin of 3D-printed parts to a specific machine and to improve the accuracy of DNA profiling 2 .
New strategies are being created to identify hazardous pollutants in soil and to improve the detection of gunshot residues, making chemical analysis faster and more precise 2 .
Technologies like CSIxR use virtual reality to simulate crime scenes, allowing for immersive training and remote analysis by investigators 2 .
The journey into forensic science begins with a solid educational foundation. Programs like those at the University of Florida equip students with the critical thinking, technical knowledge, and practical skills needed to excel. From understanding the artifacts of decomposition to analyzing digital evidence, the curriculum is designed to meet the demands of modern crime laboratories and law enforcement agencies 1 4 .
