DNA as Pattern Evidence

Pattern evidence is regarded as evidence that can be analyzed and read from a particular type of pattern that has been left by way of physical contact between different objects, different people or persons and objects. This paper discusses whether DNA can be considered as a type of pattern evidence.

When these collisions happen they result in the formation of various designs such as imprints, residues, recesses, striped markings and depositions. An example of a source that can result in the formation of a pattern is blood spatter, footwear, shattered glass, projectile trajectories and even tire skids and marks. DNA cannot be considered as a type of pattern evidence because it is a substance that is collected from other material that causes the patter such as blood, or saliva. DNA cannot be seen by the naked eye and as such cannot be classified as a type of pattern evidence (Bevel et al 2008). The use of specialized equipment such as a microscope is needed to look at DNA and when analysis is done it can be able to provide evidence on the timing and the nature of the crime including many other details such as who was present at the crime scene. Other sources carrying the DNA are the ones responsible for making patterns that can then allow for the collection of cells which are analyzed in laboratories so as to find out relevant details of a crime and who was involved (Wonder 2011).
