Latent Print Development
This lecture on latent print development includes types of prints; deposition factors; surface types; process selection; evidence handling; packaging; and the composition of latent print residue.
Preservation of Friction Ridges
This lecture on the preservation of friction ridges includes preservation through photography and the collection of fingerprints.
Documentation of Friction Ridge Impressions
This lecture on documentation of fingerprints includes general crime scene documentation; collecting Items of evidence; latent print development and recovery on scene; and marking lifts.
Developing Fingerprints on Cartridge Cases
Recovered cartridge casings can be dipped into diluted or undiluted gun blueing to cause a chemical reaction between the blueing and the fingerprint residue on the casing.
Developing Latent Fingerprints with Black Powder
Learn how to develop latent fingerprints using black fingerprint powder.
Developing Latent Fingerprints with Super Glue
Learn how to develop fingerprints with cyanoacrylate (super glue).
Developing Latent Fingerprints with Magnetic Powder
Learn how to develop latent fingerprints using magnetic fingerprint powder.
Using Mikrosil to Lift Fingerprints from Irregular Surfaces
Learn how to use Mikrosil to lift black powdered latent fingerprints from irregular surfaces.
Fingerprint Classification Part 1: Fingerprint Pattern Interpretation
This video covers the three basic fingerprint patterns (arches, loops and whorls) as well as their subcategories. It includes classification terminology and nomenclature of each pattern.
Fingerprint Classification Part 2: The Henry Classification System
Learn how to classify the fingerprints on a ten print card using the Henry Classification System.
Fingerprint Classification Part 3: The NCIC Classification System
Learn how to classify the fingerprints on a ten print card using the NCIC Classification System.
Fingerprint Comparison Part 1: Friction Ridge Identification
Learn how to compare fingerprints.
