Fingerprinting has been used as a means of identification for over 100 years, becoming a staple in forensic science. The process of collecting, analyzing, and comparing fingerprints has evolved over time, but the fundamentals remain the same. Here are the 5 essential steps to fingerprinting.
Step 1: Preparation
Before taking any fingerprints, it’s essential to prepare the equipment and the area. Ensure that the fingerprinting card is clean, and all necessary items like ink and rollers are readily available.
Step 2: Recording fingerprints
Place the subject’s fingers on the inkpad and slowly roll them from one side to the other. Then, take a print of each finger on the fingerprint card, ensuring that each print is clear and distinct.
Step 3: Label and annotate cards
Once all ten fingers are recorded, label each card appropriately and annotate it with the identifying information of the subject, including their name, date of birth, and any relevant case numbers.
Step 4: Classification and Identification
After the prints are labeled, it’s time for the comparison process. Classify the prints by identifying their pattern type (arch, loop, or whorl), and then compare them to other known prints in the database.
Step 5: Verification and Analysis
Finally, verify the match through the use of specialized software and analysis techniques. If a match is confirmed, the evidence can be used to link a suspect to a crime scene.
Fingerprinting remains a vital tool in forensic science, allowing investigators to link individuals to a crime scene with a high degree of accuracy. As such, it’s essential to follow these 5 essential steps to ensure that the obtained evidence is reliable and admissible in court.
