Evidence at a crime scene is susceptible to adverse environmental conditions such as rain or water submersion. This poses a challenge for forensic technicians when processing this evidence for latent prints. This study aims to explore the quality of latent print development on 720 prints using RAY, Rhodamine 6G, and Optimized Crystal Violet after nonporous surfaces were submerged in water. Three different surfaces underwent a specified aging period prior to cyanoacrylate fuming, followed by dye stain processing. The data indicates that RAY and Rhodamine 6G produce favorable latent print enhancement capabilities throughout each time frame on each surface. Additionally, a new chemical formula, Optimized Crystal Violet, provided fair to average results under this study’s objective.
