The Unique Properties of Sand: Its Use as Criminal Trace Evidence

Whittney Laderoute

Sand was collected and analyzed from five beaches in the upper peninsula of Michigan: The Shallows, Brimley State Park, Point Iroquois, Big Pine and Pendillís Creek. Tests were undertaken in order to determine the reliability of sand as trace evidence in criminal investigations. Size and visual comparisons were made using a compound light microscope and chemical composition was determined by using SEM-EDS analysis. Results showed several size trends and SEM-EDS trends but gave no concrete evidence to suggest that the sand used in this experiment can be used as reliable trace evidence. Further research is necessary to confirm or deny this.
