Types of trace evidence that could be recovered include skin, glass fragments, body hair, fibers from clothing or carpets, soil particles, dust and bodily fluids. The study of this trace evidence could be used to link a piece of footwear to a location or owner. DNA can be one of the contributing factors in forensic footwear evidence.
Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11] This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required.

Forensic podiatry is a subdiscipline of forensic science in which specialized podiatric knowledge including foot and lower-limb anatomy, musculoskeletal function, deformities and diseases of the foot, ankle, lower extremities, and at times, the entire human body is used in the examination of foot-related evidence in the context of a criminal investigation.
Forensic DNA analysis takes advantage of the uniqueness of an individual's DNA to answer forensic questions such as paternity/maternity testing and placing a suspect at a crime scene, e.g. in a rape investigation. Forensic engineering is the scientific examination and analysis of structures and products relating to their failure or cause of damage.
The US government's own Combined DNA Index System (CODIS) database is composed of forensic evidence assessable to local, state, and federal law enforcement officials. This database consists of genetic profiles of approximately 18 million different people, however these are limited to DNA samples from convicted felons and arrestees. [26]
Forensic DNA analysis can be a useful tool in aiding forensic identification because DNA is found in almost all cells of our bodies except mature red blood cells. Deoxyribonucleic acid is located in two different places of the cell, the nucleus; which is inherited from both parents, and the mitochondria; inherited maternally.
Forensic chemistry is the application of chemistry and its subfield, forensic toxicology, in a legal setting. A forensic chemist can assist in the identification of unknown materials found at a crime scene. [1] Specialists in this field have a wide array of methods and instruments to help identify unknown substances.
Forensic biology is the application of biological principles and techniques in the investigation of criminal and civil cases. [1] [2]Forensic biology is primarily concerned with analyzing biological and serological evidence in order to obtain a DNA profile, which aids law enforcement in the identification of potential suspects or unidentified remains.
