Introduction

Forensic science is an indispensable part of investigations and the criminal justice system. The application of scientific methods into the criminal justice system has advanced criminal investigations with precise means of identifying criminals and solving crime. Forensic science involves biology, chemistry, and physics – and technology, and applied to a criminal investigation. Forensic science is constantly developing – with new challenges and new technologies that impact how the criminal justice system functions and the values on which those systems are based. This dissertation will give you a comprehensive overview of forensic science, practices, challenges, and advances, to assess the role of forensic science to the criminal justice system.

Background Context

Forensic science has evolved greatly since first being used, with modern forensic technologies such as DNA analysis, digital forensics, and toxicology becoming intrinsic parts of a forensic investigation. Forensic science allows for crime scene analysis, evidence collection, and aids in legal processes. As the forensic sciences matured, so too have the methods used, making evidence collection and analysis more reliable, accurate, and timely. Forensic investigation, evidence, technical issues, emerging technologies, and the use of forensic science in the courtroom continue to be contentious issues. This dissertation will address all the contentious issues mentioned above while orienting the discussion towards various areas of legal issues, technological advances, and the ethical considerations of forensic practice.

Future Research Topics

  • DNA Forensics: Investigate the usage of advancements in DNA analysis, as it relates to cold cases, wrongful convictions, and exonerations.
  • Digital Forensics: Investigate how digital evidence impacts criminal investigations, cyber security, and data extraction.
  • Forensic Toxicology: Explore the relationship toxicology has to crime scene investigations, and the implications of these reports in legal cases related to toxicology.
  • Forensic Pathology and Medical Investigation: Explore how forensic pathologists utilize evidence to identify causes of death and how their opinions play a role in criminal trials.
  • Forensic Anthropology: Investigate what anthropologists do to identify remains and their use in crime scene investigations.
  • Forensic Psychology: Investigate how psychology is used in criminal investigations and psychology’s role in criminal profiling and interrogating suspects.

Dissertation Topic 1:

The Impact of DNA Analysis on the Justice System: From Cold Cases to Wrongful Convictions

Background Context

Recent developments in DNA evidence in forensic science has impacted the resolution of cold cases and false convictions. This dissertation will focus on how cutting-edge advancements in DNA technology have assisted the criminal justice system in resolving cold cases, the establishment of DNA databases, and use of familial searching.
Research Questions
  • In what ways did DNA analysis help to resolve cold cases as well as help prevent wrongful convictions?
  • What ethical or legal issues may arise when DNA is utilized in criminal cases?
  • What obstacles or limitations might DNA face in forensic investigations?
    • Potential Implications
  • A review of the role of DNA within criminal justice systems with an emphasis on wrongful convictions.
  • Recommendations for developing reliable procedures, processes and protocols to yield potentially at a trial, evidential DNA that is accurate as well as reasonable fair.
  • An examination of ethical and privacy issues associated with DNA and genetic information in relevant investigations.

    • Dissertation Topic 2:

    Digital Forensics: Addressing Cyber Crime and Data are Evidence in Criminal Investigations

    Background Context

    Digital forensics is a crucial element of current criminal investigations, because of the rise of cybercrime. This dissertation will investigate how digital evidence (emails, social media consumption, financial documents) is extracted, and last potentially presented to the court, as part of criminal proceedings.

    Research Questions
  • How do digital forensic practitioners extract and subsequently analyze data from digital devices as a result of a criminal investigation?
  • What challenges are there regarding maintaining the integrity and authenticity of digital evidence?
  • How does digital forensics aid in the resolution of modern-day crimes, such as identity theft, fraud, and hacking?
    • Potential Implications
  • Outline a summary of how digital forensics practices and processes would contribute to the field of criminal justice.
  • Develop policy recommendations on how digital forensics should be used in, or adapted for, cybercrime investigation.
  • Include many legal and ethical issues, – including, privacy and data protection issues.

    • Dissertation Topic 3:

    Forensic Pathology: Determining Cause of Death in Criminal Cases

    Background Context
    Forensic pathologists are a vital component as it relates to determining the cause of death evidenced in any criminal investigation. The dissertation will consider the role of forensic pathology in determining the manner of death, e.g., homicide, suicide, accidental.
    Research Questions
  • How do forensic pathologists assess the cause of death and how do they overcome the challenges of interpreting autopsy results?
  • What is the role of forensic pathology to the identification of natural deaths and criminal homicides?
  • How does the interpretation of post-mortem toxicology aid the investigation of deaths because of drug overdoses and or poisonings?
    • Potential Implications
  • A detailed examination forensic pathology method and its implications in criminal investigations.
  • A summary of the legal implications of autopsy results in a criminal matter.
  • Recommendations for improving forensic pathology practice in the investigation of deaths.
    • Suggested Reading

    • Conclusion

    Forensic science is a changing field and continues to change with developments in technology and techniques. From DNA analysis and digital forensics to forensic pathology and toxicology, forensic scientists play a key role in solving crimes and upholding justice. The papers listed within this Dissertation outline will provide some insight into the future of forensic science and the ways in which new techniques and research will influence criminal investigations and the judicial process.
