Criminal Investigation - Essay Example

From the pictures taken of the blood stain on the husband’s clothing, the pattern of the blood on the cloth is that of the contact transfer. In this essence, it elaborates that the husband was in contact with the victim after the victim was stabbed. Drawing from the explanation of the husband on nature with which he got into contact with the blood through an attempt to comfort the wife, the pattern thus concurs with his story. The absence of the husbands blood on any of the surfaces through a DNA test was equally an indicating factor that there had not been a struggle between the husband and the wife.

This simulates that the husband was truly not present at the time of the stabbing. Analysis of a blood pattern on a surface coupled with scientific tests like the DNA is thus a significant step in the identification of the direction of evidence (Englert, 2010).Discussion 2. The profiling of DNA is a complicated undertaking biological exercise. Nevertheless, the technology has a great implication on the manner with which investigation and evidence unveiling has been revolutionized. The use of the technology has aided in the solution of a multiple of cases some of which had been labeled as cold cases thus acting as an important milestone in the issuance of justice in the judiciary process.

The success of DNA identification of evidence, the process of collection, handling, and storage of evidence is crucial. This is because biological pieces of evidence have higher incidences of decaying, which may alter the genetic composition through a series of genetic mutation and adaptation (Krimsky, 2011). The use of DNA has revolutionized the aspect of the criminal investigation in a number of ways. In the first instance, technology has resulted in the provision of speed with which investigation work can be conducted.

With the availability of the technology, it is easy to analyze and cross-match pieces of evidence thus solving the crime much faster. Equally, technology has led to a reduction in the cost of the investigation. As much as the initial installation and analysis of the DNA equipment may be expensive, its value in the reduction in investigation cost is significant. The technology reduces the number of personnel involved in the investigation process as well as eliminating the prolonged time require.

Illustrating the importance of DNA technology is the case of the Boston Strangler. The DNA findings from the blood samples of one of the victims of Albert De Salvo provided a crucial turning point in the conclusion of the case that would have otherwise been not solved without the aid of the technology. The DNA only broke the immense caution taken by the criminal after strangling the victim in termination of the evidence (Krimsky, 2011).
