Abstract | Fingerprints are an important type of evidence within the criminal justice system, and these have been The purpose of this research was to overcome some of these issues focusing specifically on fingerprints in/on anti-climb paint, leaves, and feathers. The effectiveness of cyanoacrylate ester fuming (CEF) was implemented for all exhibit types, with the addition of physical developer (magnetic powder) on leaves and feathers (chapter 4). The adhesion of the physical developer was consistent throughout feathers, and green leaves, but varying results were obtained from brown leaves. The overall recovery types chosen were lifting (J-lar tape lift and gel lift), and casting (Provil and resin), with varying results being obtained both in terms of ridge detail recovered, as well as damage caused to the exhibit. CEF development on anti-climb paint produced robust fingermarks and was therefore suitable for casting, due to the presence of three-dimensional features (chapter 3). Casting methods captured a good level of ridge detail, with a small number of limitations, primarily caused by the quality of the original fingerprint deposit. Recovery techniques proposed within this work allow for preservation of ridge detail on a surface previously considered difficult in practice. |
