A Validation Study Of Blueview™ Gunpowder Particle Testing Kit, Hanna Lester
Honors Theses
The examination of gunshot residue is often an integral part of evidence processing. The aim of this preliminary study is to validate the use of the BlueView Gunshot Particle Test Kit in the field. This was done by comparing the results of the presumptive tests using the BlueView Gunshot Particle Test Kit to confirmatory test results using a scanning electron microscope. This study used both collection techniques to collect samples for presumptive tests and confirmatory tests. Gunshot residue samples were collected from the hands after a series of guns were fired, and positive results were obtained from the presumptive and …

A Validation Study Of Zar-Pro Fluorescent Blood Lifting Strips, Carter L. Depew
Honors Theses
It is well known within the latent fingerprint discipline that collection of bloody impressions can be difficult and destructive. This pilot study aims to validate the use of Zar-Pro Fluorescent Blood Lifting Strips© in the collection of bloody fingerprint impressions, and then compare the technique outcomes that of the currently used method – photography. This study used both collection methods to extract bloody impressions from white copy paper and aluminum metal. The impressions were aged over a two-week period prior to collection. A numerical score – representative of the identifiable minutiae points – was then obtained using the Smart Extract …
