We leave fingerprints on everything we touch hundreds of times a day. We leave them on drinking glasses, silverware, computer keyboards, toys, door knobs, water faucets, books and more. Even though we leave them everywhere, we don’t notice them at all. At a crime scene though, these left behind prints can be very important. Even one fingerprint can solve a case.
The skin on the palms of our hands and on our fingertips are covered with a pattern of ridges. You don’t even need a microscope to see them. These ridges help us grip things. Every single person has a different pattern of ridges. Even the hands and fingers of identical twins are different. The ridges stay the same throughout a person’s life too. These facts are what make fingerprints so useful for crime scene investigators. Fingerprints don’t lie. Today, you will learn how to take other people’s fingerprints.
