PRPA Crime Scene Management/Physical Evidence Practice Test

Glass analysis is a critical process in forensic investigations and can yield various types of evidence. It is particularly valuable for reconstructing events and understanding the context of a crime scene. When analyzing glass, forensic experts can determine the direction of force that caused the glass to break, which can assist in reconstructing how an incident occurred. This includes identifying patterns related to bullet holes, such as entrance and exit points, which can indicate the path of a projectile.

In addition to this, glass fragments can also potentially retain other forms of evidence like fingerprints when individuals come into contact with the glass surfaces. While DNA is not inherently part of glass, if a person leaves fingerprints on a glass surface, analysis of those prints can be conducted, which may sometimes include DNA if biological material is present.

Thus, the type of evidence that glass analysis can reveal encompasses not only information about force and impacts but also the potential for identifying individuals through various means. The holistic approach to glass analysis demonstrates its multifaceted role in forensic science, making it clear that all these aspects of evidence—direction of force, fingerprints, and potential DNA—can be derived from analyzing glass at a crime scene.
