A suspect may say that they were not present at a crime scene and that they were elsewhere at the time that a crime was committed. One approach available to the forensic analyst is to study any residues left on the clothing of the suspect from the time of crime and compare them to material from the alibi site to see if the alibi could potentially be true. One such residue is mineral grains, often found in the form of mud on shoes. Similar to gunshot residue analysis we provide solutions to examine trace evidence from soil and other sources that can conclusively tie a suspect to a crime scene.
