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.

Face Recognition

Face Recognition

artofcrimedetection_regRemembering a face is important, especially for the witness of a crime. A police sketch artist is trained to draw a picture of a suspect based on what a witness can describe about the suspect’s face. In the game The Art of Crime Detection you will witness two crimes. After each, you will be asked to help sketch a picture of the suspect. At the end, you can read an interview with a real police sketch artist.

Next, you can play How is Your Memory for Faces? You will look at a face and try to memorize features on the face so that you re-create what you saw. It’s harder than it sounds.

If you’re doing some secret surveillance, you might want to consider a disguise. Sometimes, it’s better to hide in plain sight, if you know what I mean. You can add some useful stuff to your detective kit by gathering up some simple things that will effectively disguise you: hats, sunglasses, hair gel, & a fake ponytail are good starters! What else can you think of that would be easy?

Try some of these games to see how changing just one or two things about a person’s features can effectively change how that person looks.

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.
