What is the correct procedure to recover latent prints on dusty surfaces?

The correct procedure for recovering latent prints on dusty surfaces primarily involves the proper use of lighting and photography. This method utilizes the interaction between light and the dust or particulate matter on the surface to enhance the visibility of latent prints. By carefully adjusting the angle and intensity of the light, it is possible to bring out the details of the prints that may not be readily visible to the naked eye. Photography plays a crucial role in documenting the prints before any physical recovery methods are applied, ensuring that the evidence is preserved accurately.

Using water to wash the surface may wash away the latent prints entirely, as they are often fragile and can be easily removed by moisture. The application of super glue, which is known as cyanoacrylate fuming, is typically effective on non-porous surfaces but may not be the first choice for dusty surfaces compared to the consideration of lighting and photography. Directly touching the surface with tape can also disturb the print or remove it entirely, potentially leading to the loss of the evidence needed for further analysis. Therefore, the correct approach begins with enhancing the visibility of the latent prints through lighting techniques and capturing them photographically before proceeding with any further recovery methods.
