Which of the following is considered a type of trace evidence?

Trace evidence refers to the small amounts of materials that are transferred from one location to another or between individuals during a crime. This evidence often consists of microscopic particles and can be crucial for linking a suspect to a crime scene or victim.

Dust and fibers are indeed classified as trace evidence. They can come from clothing, textiles, hair, or environmental sources, and are often found in very small quantities at crime scenes. For example, fibers can transfer from the clothing of a perpetrator to a victim or vice versa, providing valuable connections in an investigation.

In contrast, fingerprints and bodily fluids like blood or saliva are considered more significant types of evidence due to their ability to show direct contact or biological connections rather than mere presence. Weapons, while crucial in criminal investigations, are not classified as trace evidence since they are typically larger items that can be directly linked to an act rather than subtle material traced through contact.
