Trace Evidence

Trace evidence is based on the principle Edmond Locard developed “Whenever two objects come into contact there is always a transfer of material.”    It is recognized as one of the most diverse forensic disciplines as it offers forensic analysis in numerous areas.  The OSBI Trace Evidence Section offers analysis in the areas of fiber, paint, physical match, ignitable liquids, pressure tape and adhesive analysis, gunshot residue, and elemental analysis.
