In the crime lab, someone has come in and “stolen” valuable equipment, leaving their fingerprints behind. Your job is to find and collect the fingerprints. Click Continue to enter the lab. Click on the lab door. What do you notice? The smudge you see is a fingerprint. Drag and release the camera over the fingerprint to take a photograph. Now look at the definitions of the three types of crime-scene prints. What kind of print is an impression in a soft substance such as wax? Plastic print Latent Print Patent Print What kind of print is formed from skin oils and is nearly invisible? Plastic print Latent Print Patent Print Which print is formed from a visible substance transferred by the fingers? Plastic print Latent Print Patent Print Which type of print was found on the door? Plastic print Latent Print Patent Print Activity A: Collect Prints - Check that Collect prints is selected. Look for other visible prints by clicking on different parts of the crime lab. (Hint: There are two visible prints in total.) You can select Show all locations to see which parts of the lab you can see up close. Photograph and classify each print that you find. After analyzing the crime scene for prints.Sort each type of print found at the crime scene as either Latent, Patent (Visible), Plastic or No Print. Patent (Visible) Door Latent Laptop Chair Draw handler No Print Microscope Lamp Plastic Lab Gel Once you have collected the rest of the prints, complete the following sentences. If you touch a partially melted candy bar, a plastic print might form.If you dip your finger in ink and touch the wall, a patent print might form.If you hold a drinking glass, a latent print might form. Activity B: Classify prints After collecting the training scene prints, press Continue to go to the Classify prints step. Read the description of the three main pattern groups at the top of the screen. How can you distinguish a loop from an arch? Within each group are two or more subgroups. At the top of the screen, select Arch subgroups, Loop subgroups, and Whorl subgroups. How can you distinguish a plain arch from a tented arch? How can you distinguish an ulnar loop from a radial loop? Write a quick description of each whorl subgroup in the table below. Whorl Subgroup Description Plain Whorl Central Pocket Loop Whorl Double Loop Whorl Accidental Whorl Classify: There are three suspects in this “burglary.”Using the exemplar images, classify each of the suspect prints. To do this, drag each print into one of the subgroup bins on the right. Then classify each of the crime scene prints.

Identify: To label minutiae, drag a label from the Minutiae list on the left to the correct spot on the print. Identify as many as you can find. Repeat this process for each print. Label below the minutiae you found on the FIRST FINGERPRINT sample? Ridge ending Island Short ridge Trifurcation Spur Label below the minutiae you found on the SECOND FINGERPRINT sample? Island Spur Bifurcation Bridge Label below the minutiae you found on the THIRD FINGERPRINT sample? Ridge crossing Island Dbl. bifurcation Lake Matching. Click Continue to move on to the Match prints section. Drag the first collected print to the main area. What type of print was collected from the door? Plain Arch Tented Arch Ulnar Loop Radial Loop Plain Whorl Central Pocket Loop whorl Double Loop Whorl Accidental Whorl Select Jill Johnson, then click the right arrow (you will cycle through Marcus and Jack's prints just by clicking the arrow) until you find a print that looks identical to the collected print. Which print did you pick? When you think you have a good match, click Find minutiae. To match the prints, you will need to identify three common minutiae in the two prints. Label minutiae that match in each print. After identifying the minutiae, the Gizmo will tell you if the prints match. CLICK FIND MINUTIAE TO START MATCHING POINTS ON EACH PRINT Which suspect matched the collected print? Jill Johnson Marcus Morris Jack Davis Solve the case: Next to Compare, select Prints of the same subgroup to only see suspect prints of the same subgroup as the collected print. Match the remaining collected prints. Which suspect matched the ALL the collected prints? Jill Johnson Marcus Morris Jack Davis Under Mode, select Crime scene 1. This is a sinister case of sabotaged stew in a swanky restaurant. Use the procedures you have learned to collect fingerprints, classify fingerprints, and use minutiae to match collected fingerprints to suspect fingerprints. Use the procedures you have learned to collect fingerprints, classify fingerprints, and use minutiae to match collected fingerprints to suspect fingerprints.In Crime Scene 1, Which suspect broke into the Glitzy Gala and sabotaged the stew? Sandra Alexander Julio Horatio Under Mode, select Crime scene 1. This is a sinister case of sabotaged stew in a swanky restaurant. Use the procedures you have learned to collect fingerprints, classify fingerprints, and use minutiae to match collected fingerprints to suspect fingerprints. Which suspect (or suspects) left prints in the bedroom? Dorothy Dalrymple Marty MacMillan Nancy Nimble Which suspect is the most likely thief, and explain why do you think so?
