What type of analysis is used to match fragments of glass found at a crime scene?

• A. Forensic microscopy
• B. Glass comparison analysis
• C. Trace evidence analysis
• D. Chemical analysis

Answer: (A)

The appropriate choice for analyzing fragments of glass found at a crime scene is forensic microscopy. This technique involves using a microscope to closely examine the physical characteristics of glass fragments, such as their refractive index, color, thickness, and surface features. Forensic microscopy allows investigators to compare these characteristics between the glass fragments collected at the crime scene and known samples, helping to establish links or connections. Forensic microscopy is particularly effective because it provides detailed information that can be crucial in criminal investigations. It allows for the examination of minute details in the glass that may not be visible to the naked eye and can reveal information about how the glass was fractured, which may provide insights into the circumstances surrounding a crime. While glass comparison analysis involves comparing glass fragments, it is more of a general term that can include various methods, including forensic microscopy as a specific technique used within that analysis. Trace evidence analysis encompasses a broader range of materials and is not exclusive to glass; it can refer to the examination of any small evidence left at a crime scene. Chemical analysis may help in determining the chemical composition of glass but does not typically provide the detailed comparative information needed in this context. Therefore, forensic microscopy is the most definitive approach for matching glass fragments found at a crime scene.
