Research Proposal

This paper seeks to understand various forensic sciences and their application as practical tools to assist law enforcement officers in conducting investigations are discussed in this paper. The paper is not meant to be a thorough dissertation on all of the forensic sciences that are currently available to the readership. Instead, it is intended to serve as an overview, demonstrating the wide range of forensic tools that are currently available. A good understanding of forensic tools is essential for any investigator, even if they are not experts in any of the forensic sciences. However, it is useful to be able to call on qualified professionals to deploy the appropriate tools when the situation calls for it. For more than two decades, due to a lack of available resources, most criminal investigations do not take advantage of the significant scientific advances made in the forensic sciences during that time. Studies on DNA testing, its costs, and its effects on cold cases and property crimes have been conducted.

The purpose of this research is to determine the possible causes of this trend. Following that, a comprehensive research proposal will be developed, which will include all research questions, goals and objectives, a detailed methodology, and a timeline for completion.

Background of Research

The forensic sciences have made significant advances in the last twenty-five years, but more studies is needed to determine the impact of these developments. Only a few have looked the significance of DNA evidence in the investigative process, but none have looked at the whole range of evidence available at crime scene. This paper contains the following objectives:

Objective 1: to identify, maintain, collect, analyze, and reconstruct all appropriate physical evidence at a crime scene.

Objective 2: evaluates the integrity of research literatures based on the findings of collections of studies rather than the systematic details of individual studies, and it is regarded as the supreme authority of scientific objectivity.

Objective 3: To determine what happened in a specific incident in a thorough and trustworthy manner

Research Questions:

1. What kind of physical or chemical evidence uncovered at the crime scene that has the potential to lead a favorable conclusion in the courtroom?

2. What role does forensic evidence obtained from a crime scene and accustomed to laboratory processing play in assisting law enforcement in the investigation of crimes?

3. How do latent print examiners ensure that accuracy is not affected by analytic procedures that may arise from individual differences?

4. What is the quality control measures for the whole forensic science?
