Handwriting Analysis

Handwriting Analysis

Handwriting Analysis

No two people write in exactly the same way. Detectives use handwriting analysis to solve mysteries. A handwriting expert can tell whether or a not a person wrote a letter or note. Even if a suspect tries to disguise their handwriting, a good handwriting expert can tell. The more samples of the suspects handwriting there are, the easier it is for the expert to identify writing patterns of the person being tested.

Try out your skills analyzing handwriting playing these two games: CSI Handwriting Analysis Game (scroll to game 2) and Fetch CSI: Tugboat Thug.

Fingerprints

Fingerprints

Fingerprint Evidence We leave fingerprints on everything we touch hundreds of times a day. We leave them on drinking glasses, silverware, 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.

Now, learn how to take a fingerprint from an object – this is called picking up latent fingerprints. These are the fingerfetchhat_regprints that have been left behind. One way detectives find fingerprints is by dusting the crime scene for them. Fingerprints are coated with powder, then lifted and taken to a lab for identification.

Here are three website that can help you learn all about dusting for fingerprints.
