| Abstract |
This study aims to examine the quality of latent fingerprints on non-porous surfaces, including plastic, glass, and metal, under normal conditions (room temperature) and while submerged in different types of water natural water sources and deionized water. The study was conducted over varying periods of 1, 3, 7, 14, and 28 days. The methods used for latent fingerprint recovery were black powder dusting and cyanoacrylate fuming followed by staining with Basic Yellow 40. Before processing, the samples were dried at room temperature. The recovered latent fingerprints were photographed in a laboratory setting using a digital camera, and the images were then provided to experts from the latent fingerprint analysis unit to assess the fingerprint quality based on the clarity and the number of visible ridge lines.
The results showed that under normal conditions, latent fingerprints recovered using both black powder dusting and cyanoacrylate fuming with Basic Yellow 40 yielded high-quality prints with clear ridge detail, suitable for comparison and identification purposes. However, for samples submerged in water for different periods, the increasing duration of submersion resulted in a decrease in ridge clarity. Additionally, the type of water significantly impacted fingerprint recovery. The study found that fingerprints submerged in deionized water (DI) exhibited clearer ridge detail compared to those submerged in natural water from Bueng Kaen Nakhon. Furthermore, the cyanoacrylate fuming method followed by staining with Basic Yellow 40 was more effective in recovering latent fingerprints than the black powder dusting method.
