Paper Summary:
This paper lays out how DNA has become a vital tool is criminal investigations. Areas that are discussed are how even with the smallest drop of blood it can link a suspect to a crime. The paper shows how the use of DNA database evidence also assists in solving old crimes by linking a suspect. As the technology continues to change DNA will be extracted from many other areas such as even fingerprint oils. DNA testing has accomplished a great deal in opening up new sources of forensic evidence, its full potential to identify perpetrators and exonerate people falsely convicted has yet to be realized.
From the Paper:
"First developed in England in 1985, DNA testing takes advantage of the fact that, with the exception of identical twins, the genetic material of each person is unique. DNA is the chemical deoxyribonucleic acid, which carries the genetic code of each human's body, the genetic blueprint we inherit from our parents. DNA, while not actually a part of saliva, urine, perspiration or tears, is found in one place, the nucleus of cells. Since these cells are found in all bodily fluids, tissue and hair, DNA is an omnipresent residue that trails us wherever we go. These physical properties of DNA have made it an important tool in fighting crime."
