DNA typing of trace DNA recovered from different areas of sandals found at a homicide crime scene investigation: A comparative study

Abstract

Trace DNA recovered from worn or handled items collected from crime scenes may link the offender to the crime scene, helping criminal investigations in identifying the perpetrator. In this study, we compared DNA yields and DNA profiles obtained from different sampled areas of a pair of sandals found at a homicide crime scene. We obtained DNA profiles from all sampled areas. Trace DNA recovered and DNA profiles obtained played a very important role in the identification of the murderer, linking him to crime scene. This information together with other evidence proved decisive in court. Those results highlight the importance of trace DNA in helping criminal investigations.
