Abstract
Can everyday ingredients from the kitchen function similar to forensic powders that are used for crime scene analysis? In this research project, The Unseen Revealed: “from pantry to The forensic bench”, we look to see if there are alternative household powders that can be used to develop and visualize latent fingerprints instead of expensive forensic powders in the market that one would generally rely on. The research includes three major objectives. The first is to evaluate the effectiveness of using selected spices and starch particulates to visualize latent fingerprints. The second is to compare the performance of the selected household powders used to visualize latent fingerprints in regard to clarity of the print, ridge detail of the print, and contrast to the selected surface type, to that of commercial forensics powders. The third is to evaluate the general perception of the usability, safety and practicality of the household powders used in the study. A systematic and structured method was used to conduct this research. The research was conducted under strict controlled conditions to ensure that accurate and reproducible results were achieved. As part of the study, many different household powders were tested for their ability to visualize latent fingerprints; however, very few would produce a satisfactory print visualization. Two powders produced satisfactory prints; they were cornflour when used on dark surfaces and cocoa when used on light surfaces. We completed 100 latent fingerprint collections from many different locations and surfaces types; after that, the prints were visualized with the two selected powders and lifted off of the surfaces to conduct more detailed analysis. The outcomes were really quite amazing. Corn flour and cocoa powder effectively made latent fingerprints visible, delivering sharp details of ridges and high contrast within minutes. In a side to side comparison with the traditional forensic powders, these two domestic alternatives were found not only highly effective but also very inexpensive and quite easily available. Besides, people who tried them considered these powders safe and simple to use under real operating conditions.From what we have observed, we are of the opinion that household powders that are readily available and are widely used - In particular corn flour and cocoa powder - may be used as alternatives to traditional forensic materials for latent fingerprint enhancement. This is more so in cases where forensic budgets are very limited or it is difficult to obtain commercial powders. Our research highlights the possibility of incorporating cheap and readily available materials in forensic work without sacrificing the level of performance or dependability. Besides, this study paves the way for further exploration of forensic science by proving that typical, low-cost solutions can work well and be environmentally friendly at the same time. Actually, it turns out that the most powerful instrument may not really be deep inside a laboratory but rather right there in your kitchen cup board
