Use of Magneto-Rheological Fluids for Collecting, Preserving, and Analyzing Toolmark and Impression Evidence

The purpose of this research is to develop a novel technique to collect both impression and tool mark evidence that eliminates the need for mixing of materials on site as well as the possible human errors that come along with it. The research hopes to eliminate the loss of detail of the impression from incorrectly made materials, and to eliminate the waiting time needed for a casting to set. The goal set forth in this research is to optimize the use of Magneto-rheological fluids in a forensic science setting, specifically in impression and tool mark evidence. The objective is to discover if utilizing Magneto-rheological (MR) liquid, as an agent to capture impression and tool mark evidence, is feasible.
