Which type of evidence includes soil linking a suspect to a crime?

• A. Biological Evidence
• B. Trace Evidence
• C. Digital Evidence
• D. Controlled Substances

Answer: (B)

Soil linked to a crime is trace evidence because it consists of tiny, often microscopic particles that can transfer between people, clothing, and objects during contact. These small amounts of material can be collected from a suspect’s shoes, clothing, or gear and compared to soil from the crime scene. Forensic analysis looks at the mineral content, texture, and other characteristics to see if the soils could come from the same location, which can support an association between the suspect and the scene. This type of evidence is typically considered class evidence, though unique soil features can sometimes offer stronger specificity when used with other data. In contrast, biological evidence involves organic material like DNA or blood, digital evidence concerns electronic data, and controlled substances refer to illegal drugs.
