Answer

Associative evidence gives a connection between evidence and people associated with a crime. Associative evidence includes either fingerprints or DNA and can be enough to prove involvement in a crime (Lyle, n. d). Other times can provide an association of different pieces of evidence. Associative evidence is classified into two groups: class evidence and individual evidence. Class evidence includes glass and paint, while examples of individual evidence are blood and fingerprint. Individual evidence is more specific as it narrows down to a particular individual than class evidence that does not prove involvement in a crime as they do not narrow down to a single person.

Class evidence is an example of physical evidence linked only to a group with the same properties. Class evidence is used to decrease the number of suspects but cannot specify a single individual (Lyle, n. d). Thus, class evidence does not prove involvement in a crime. Examples of class evidence include carpet fibers and blood groups. To find sufficient proof of involvement in a crime, one needs to find different kinds of substances to link the suspect to the crime.

Individual evidence is also an example of physical evidence connected with a common source and has a high level of certainty; thus, it can prove involvement in a crime because it can only belong to one individual. Examples of individual evidence include DNA, fingerprints, and fragments of glass that can fit one another (Lyle, n. d)

In summary. individual evidence is more specific as they narrow down to a single individual; however, class evidence does not prove involvement in a crime as they do not narrow down to a single person. Examples of individual evidence include DNA, fingerprint, and glass fragments that fit one another. On the other hand, examples of class evidence include blood groups and carpet fibers.
