Description
The goal of this research project is to develop a fingerprint fumigation method that effectively visualizes latent fingerprints in a single fumigation step, making a secondary visualization method (like dusting) unnecessary. This will be done by dyeing the cotton balls used during the fumigation process with common dyes found in permanent markers (Sharpie), washable markers (Crayola), and other name brand markers. As cyanoacrylate glue reacts with the dyed cotton balls (treated with baking soda), the colored vapors will adhere to the latent prints. This will color the latent prints to increase the contrast between the print and the surface. Other altered fumigation methods will be tested as well.
