Description

Fingerprinting

In an indoor area, identify three different non-porous objects on which you can place and subsequently collect fingerprints. Using your index finger, wipe your finger along the edge of your nose, where the nose meets your cheek. The purpose is to obtain natural body oils on your finger from which you will make latent fingerprints on various objects. Then roll your finger on a non-porous object to create a latent impression. Repeat the process using two other people to create the impressions.

Using fingerprint powders and brushes develop each latent impression. Avoid using too much powder to make these impressions very dark. Use a very light, soft touch with little fingerprint powder and develop slowly, because latent fingerprints can be overdeveloped or destroyed with too much powder or pressure exerted by a brush.

Once the latent fingerprints are visible, photograph the impression and then try to collect each impression using the technique demonstrated in the classroom.

When you find the characteristics, upload the images of your fingerprints into a 10- to 12-slide Microsoft PowerPoint presentation. Your presentation should cover the following areas:

  • Display the fingerprints you have developed.
  • Identify whether each print exhibits a loop, whorl, or arch.
  • Identify as many Galton features as you can, using proper terminology.
  • Describe the method you used to develop these prints
  • Last, describe how investigators could use these developed prints to possibly identify a suspect.
    • Support your responses with examples.
    • Cite any sources in APA format.

introduction
• Figure prints are essential components in forensic analysis
• They can be used to identify suspect in any case
• In most cases suspect leaves figure prints without noticing
• If forensic expert get these figure prints they are in position of getting
the suspect.
• With this justice can be served
• Although modern criminals are advancing figure prints still plays an
important role in the forensic study

Galton features
• Ridge edge
• Delta
• Fork
• Sweat pores which give the of a dotted ridges
• Crossover
• Core
• Bifurcation

• I used the finger print powder to develop these prints
• The print powder gives the required impression of the figureprin...
