Investigating Fingerprint Quality on Different Coated Surfaces

CSEF · 2007 Materials Science (Junior Division Only)

Emily E. Luna · Washington Academic Middle School, Sanger, Fresno County

Overview

Objectives/Goals A crime scene could have fingerprint on several different surfaces and those surfaces could be covered with different coatings. An Officer at the crime scene would probably find a good fingerprint on certain surfaces with certain coatings,so my project will be determining which surfaces and coatings will have good quality fingerprint. Methods/Materials My method is the fingerprint Dusting method. Materials: Aluminum metal,raw wood,glass, non-sterol gloves,non- stick cooking spray,white paint, house dust and latent print field kit. Results My resalts were that paint on glass and metal and dust on glass had better qualitys then wood with any coating. Conclusions/Discussion I found out that my hypothesis was wrong and never look at wood first.

Summary statement

About finding good qualitys on a coated surfacein a crime scene.
