Name a type of evidence that can be categorized as class evidence.

Class evidence refers to material that connects an individual or group to a certain group, but not to a specific source. It is characterized by its ability to narrow down the pool of suspects or objects to a specific category, rather than linking directly to one unique individual.

Shoe treads or clothing fibers qualify as class evidence because they can be associated with a particular brand or type of shoe or clothing, which can indicate the general population that may wear such items. For instance, a specific tread pattern can link evidence to a certain type of shoe but cannot definitively tell you which individual wore that shoe. This means it helps to establish a connection within a broader context, allowing investigators to focus on a group that might possess similar characteristics.

In contrast, fingerprints are considered individual evidence because they are unique to each person and can be matched to a specific individual. DNA samples also provide individual evidence since every person (except identical twins) has unique DNA that can definitively link evidence to a single person. Personal belongings might indicate an individual, but they do not fit the definition of class evidence because they are typically specific to one person. Thus, shoe treads or clothing fibers exemplify the nature of class evidence, as they commonly relate to groups rather than individuals.
