What type of analysis can reveal manufacturer and other information about a source item?

• A. Trace evidence analysis
• B. Fiber analysis
• C. Toolmark analysis
• D. Ballistics analysis

Answer: (B)

Fiber analysis is integral in crime scene investigations, particularly for revealing manufacturer information and tracing the origin of source items. This specific analysis processes fibers found at a crime scene, which can include textile fibers from clothing, carpets, or other materials. The characteristics of these fibers, such as their color, chemical composition, and microscopic structure, can help forensic analysts determine the specific type of fabric and potentially link it back to a manufacturer. This is essential in criminal investigations because it allows investigators to create connections between suspects and victims, or to identify sources related to the crime scene. Fiber analysis can also assist in establishing a victim’s clothing or where a crime may have occurred, amplifying its evidentiary value. While the other types of analysis mentioned are important in their respective fields—trace evidence analysis looks at tiny materials that can provide critical information about the crime scene; toolmark analysis examines impressions left by tools at a crime scene; ballistics analysis analyzes firearms and ammunition—they do not provide the same direct link to the manufacturer's information concerning a source item in the way fiber analysis does.
