This article examines methods in detecting and collecting dust impressions at crime scenes.
Abstract
Dust impressions at a crime scene can be very challenging to find. The best way to search for a dust impression is to place a bright flashlight on the floor and allow the light to skim across the floor. In 1965, a method was developed in detecting and collecting dust impressions at crime scenes. It entailed rubbing the surface of a black celluloid sheet with a woolen cloth to generate static electricity. The static electricity caused the dust impression to cling to the celluloid sheet, lift off the floor, and appear distinctly on the sheet. Today’s static dust lifters use a Mylar film. Once the impression has been lifted onto the film, it is imperative it be packaged and preserved properly for submission to the lab for documentation and comparison. In documenting an impression, such as a shoe impression photographs should be taken to establish the location of the impression within the scene. The evidence found beneath one’s feet can now result in the apprehension of the criminal or suspect. It is imperative that first responders and crime scene technicians be aware of the possibility that dust impressions, and the transferring of the dust from shoes to surface, exist at crime scenes. They must make every effort, through available technology, to preserve, document, and collect it.
