yiseo@korea.krIf we analogize any external physical force applied to victims of crimes involving violence, it would be possible to not only presume the mutual action between victims and suspects but also deduce more facts related to the cases. Therefore, in this study, defining the phenomenon of amino acid compounds in sweat spreading into clothes as impact marks, experiments using ninhydrin, 1,8-dizafluoren-9-one (DFO), 1,2-indanedione-zinc (1,2-IND-Zn) were conducted to determine developmental variations through change over time, which was not performed in previous studies. A 5-week period was set up including first damage as a variation factor, and materials in each action were developed using certain reagents. The level of specimen development depending on the change over time was identified. Thus, no changes were observed at each initial level of development. Key Words: Strike mark; Amino acid reagent; Porcine skin; Crime; External force | | |
