ABSTRACT
Deoxyribonucleic Acid (DNA) is an existing fundamental genetic material, a complex molecule that contains all human body cells that varies from person to person. Crime exists in one form or other in human society. 1 With the time and technological advancement in society, the methods and techniques adopted in committing crime have undergone an extraordinary change. With these changes, there is also an increase in the crime rate. DNA assessment has turned into a highly significant task; it has played an important role in the criminal justice system over recent years. 2 DNA findings often help to determine the culprits in several cases where sufficient evidence was not present. Gathering DNA evidence is complex and it must meet certain legal standards.
The criminal procedure has to standardize the collection and detection to improve the DNA evidence for court review procedures to play a better role in the court trials. 1. Smith, J.

INTRODUCTION
Introduction to DNA technology in forensic science has gradually become the main means for forensic evidence in the identification of criminal cases. 3 DNA evidence provides a powerful tool for identifying perpetrators and exonerating the innocent in the criminal justice. 4 The research determines the need to develop and amend criminal legislation to include DNA evidence and the need for a DNA database to ensure immediate identification of criminals. DNA profiling has enhanced the accuracy and reliability of forensic investigations, contributing to the resolution of complex cases where traditional methods fall short. The forensic DNA technique is a rapidly growing technique strengthening the investigation accuracy and power of the criminal justice system.
This development has reshaped evidentiary standards, courtroom procedures, and investigative techniques, making DNA a critical component in the pursuit of justice. The integration of DNA evidence raises significant legal, ethical, and procedural questions, especially concerning privacy rights, the potential for misuse, and the reliability of forensic laboratories. The court will be convinced of this evidence because of its trustworthiness as it is a reliable and authentic tool in criminal investigation. So far, DNA technology has solved more than 50,000 cases worldwide and over 600 cold cases by Investigative Genetic Genealogy (IGG). 5
HISTORICAL BACKGROUND
The history of DNA evidence in the criminal justice system marks a significant advancement in forensic science; dating back to 1984, when British geneticist Sir Alec Jeffreys first developed a technique called DNA fingerprinting. This led DNA evidence as a tool for identifying individuals based on their unique genetic identification. In 1986, this technique was applied in a criminal case for the first time in the UK, leading to the conviction of Colin Pitchfork for the rape and murder of two girls, this is a landmark case. DNA evidence was introduced in 1987 in the United States, where DNA evidence linked to a series of rapes of 3. Jeffreys, A. Genetic Fingerprinting: From Discovery to Criminal Justice.

Tommy Lee Andrews. Since then, DNA technology has become an integral part of criminal investigations, with its use expanding into areas like paternity testing, identification of missing persons, and exoneration of wrongfully convicted individuals.6 As DNA technology advanced, it became a key component in criminal investigations worldwide. Its ability to either confirm the presence of a suspect at a crime scene or exonerate the wrongfully convicted transformed the approach to justice. By the 1990s, DNA testing was being used not only in high-profile cases but also in cold case investigations and postconviction reviews. The rapid development of more efficient DNA analysis techniques, such as Polymerase Chain Reaction (PCR), made it possible to analyse even small or degraded samples, further solidifying DNA’s role in the criminal justice system.7
DNA COLLECTION AND PRESERVATION
The collection and preservation of DNA verification are critical in ensuring the integrity and solidity of the forensic analysis. DNA can be collected from the samples found at the crime scenes like blood, semen, hair, teeth, bone, saliva, skin cells, etc. 8 Proper collection methods are essential to prevent contamination, degradation, or loss of the sample. Crime scene investigators typically wear gloves, masks, and protective clothing while using sterile equipment to collect samples. Each sample is then sealed in tamper-proof packaging and labelled with the appropriate chain-of-custody documentation to ensure its legal admissibility. 9 Preservation is equally important, as DNA is susceptible to environmental factors such as heat, moisture, and light, which can degrade the sample.
Typically, biological evidence is stored in cool, dry conditions, and if long-term storage is required, freezing the samples is recommended. Forensic labs follow strict protocols to handle DNA samples carefully,

minimizing the risk of contamination. Additionally, ensuring that DNA evidence is collected and preserved properly maintains its accuracy in criminal investigations, reducing the chances of wrongful convictions or compromised results. Proper documentation of each step in the process also helps in maintaining the credibility of the DNA evidence in legal proceedings.
DNA ANALYSIS TECHNIQUE
DNA analysis techniques have evolved significantly over time, becoming faster and more accurate, which has greatly enhanced their application in the criminal justice system. 10 The most widely used method today is Short Tandem Repeat (STR) analysis, which examines specific regions of DNA that vary greatly between individuals. 11 It is highly sensitive, requiring only small amounts of DNA, and is considered reliable even when samples are partially degraded or contaminated. It is the preferred technique for forensic investigations due to its accuracy in distinguishing individuals. Another common method is Polymerase Chain Reaction (PCR), a technique that allows the amplification of tiny DNA samples. 12 It is particularly useful in cases where the DNA sample is limited, as it can generate enough material for analysis from a small or degraded sample.
These methods are faster and more efficient than earlier techniques like Restriction Fragment Length Polymorphism (RFLP), which required larger, high-quality samples and took much longer to process. For cases where nuclear DNA is degraded or unavailable, Mitochondrial DNA (mt DNA) analysis can be used. 13 This method analyses DNA found in mitochondria, which is inherited maternally and can remain intact longer than nuclear DNA. While not as precise for individual identification, it is useful for tracing maternal ancestry or identifying remains.

DNA DATABASES AND CODIS
DNA databases are vital tools in modern criminal justice systems, used for storing DNA profiles that can be matched with evidence collected from crime scenes.14 These databases play a major role in identifying suspects, solving cold cases, and linking crimes committed by the same perpetrator across different regions. Combined DNA Index System (CODIS) is one of the most prominent DNA databases, developed by the Federal Bureau of Investigation (FBI) in the United States. CODIS composed of two main databases:
1. Forensic Index: It contains DNA profiles obtained from crime scene evidence,15
2. Offender Index. It holds the profiles of individuals who were convicted of certain crimes,
including violent offenses like murder and sexual assault. When law enforcement uploads DNA evidence from a crime scene into CODIS, the system automatically searches for matches across both indices. A match can link a suspect to a crime or provide leads in cases with no identified perpetrator. CODIS and other DNA databases have helped exonerate wrongfully convicted individuals, particularly in cold cases where new evidence emerges years after the initial investigation. DNA databases also raises privacy concerns, regarding the storage of genetic information of, individuals who have not been convicted of any crime, such as arrestees or family members of offenders.16 Overall, while DNA databases like CODIS have proven to be invaluable in the fight against crime, they also require careful regulation to balance public safety with individual privacy rights.17

APPLICATION OF DNA IN CRIMINAL JUSTICE
DNA evidence offers an identification of perpetrators and exonerating the innocent. Its application spans a wide range of criminal investigations, from violent crimes like rape and murder to more complex cases involving historical and cold cases. 18 The use of DNA analysis allows investigators to establish a direct link between biological material found at crime scenes and potential suspects, making it a critical component in solving cases. 19 The most significant applications of DNA is its role in criminal identification. DNA evidence collected at crime scenes are compared to DNA samples from suspects. A match can confirm the suspect’s involvement in the crime, while the absence of a match can exclude an individual, reducing wrongful accusations.
20 In sexual assault cases, DNA testing has been especially valuable, providing direct evidence of the perpetrator's identity when bodily fluids are involved. Another crucial aspect of DNA's application is exoneration of wrongfully convicted individuals. Many cases from the pre-DNA era involved convictions based on less reliable evidence, such as eyewitness, testimonies or circumstantial facts. 21 DNA testing has been reviewing such cases and overturn wrongful convictions. Organizations like the Innocence Project have used DNA evidence to free hundreds of innocent individuals who were wrongfully imprisoned, many of whom had been on death row. DNA is also vital in cold case investigations. DNA databases has allowed law enforcement agencies to revisit unsolved cases, comparing old evidence to profiles stored in databases like CODIS.
In addition to solving crimes, DNA evidence is used in disaster victim identification and paternity disputes. After large-scale disasters, such as plane crashes or natural disasters, DNA helps identify victims when other methods, such as fingerprinting or dental records, are not feasible. Similarly, in civil cases, DNA is often used to establish paternity or familial relationships, which can influence legal decisions in custody or inheritance disputes. 18. Cole, Simon A.

The application of DNA evidence in the criminal justice system continues to expand with advances in technology, making it an indispensable tool for both solving crimes and protecting the rights of the innocent.22
LEGAL AND ETHICAL USE OF DNA EVIDENCE
The use of DNA evidence in criminal justice presents significant legal and ethical considerations that impact how it is applied in court and its broader implications for society.
1. Admissibility in Courts
The DNA evidence varies by jurisdiction. In the United States, the Daubert v. Merrell Dow Pharmaceuticals (1993) established Daubert standard which guides the admission of scientific evidence. This standard requires that DNA evidence be scientifically valid, reliable, and relevant to the case. Section 45 of the Indian Evidence Act, 1872, as per expert testimony DNA evidence is presented. Courts in many other countries have adopted similar approaches, ensuring that DNA evidence is subject to rigorous scrutiny before it is accepted in legal proceedings.23 Challenges remain in ensuring that DNA testing is conducted and presented accurately. Poor lab practices, contamination, or misinterpretation can result in wrongful convictions or the exclusion of key evidence. Legal safeguards are necessary to ensure that DNA evidence is handled correctly at every stage of an investigation.
2. Privacy and Consent Issues
DNA contains highly sensitive personal information, which raises concerns about privacy and the potential misuse of genetic data. When individuals DNA is collected during criminal investigations, questions arise about who has access to this data and how it is stored. In some countries, DNA profiles are collected from not only convicted criminals but also from arrestees, even if they are never charged.24 This raises ethical concerns, as individuals who are presumed innocent may have their genetic information stored indefinitely in databases. Consent is another significant issue.

Individuals may be required to provide DNA samples without their explicit consent, especially in criminal investigations or civil cases like paternity disputes.25 Without clear legal frameworks regulating these practices, the potential for abuse increases, leading to concerns over unauthorized use or retention of genetic data.
3. Racial and Socioeconomic Disparities
The potential for racial or socioeconomic biases in the use of DNA evidence. Minority communities are often overrepresented in criminal databases due to disproportionate arrest rates, which can lead to biased targeting in future investigations.26 This creates a vicious cycle, where marginalized groups are more likely to have their DNA collected and more likely to face scrutiny from law enforcement. Low-income individuals may not have access to the same legal resources to challenge DNA evidence in court. While DNA evidence is often portrayed as conclusive, mistakes can occur, and individuals who cannot afford expert witnesses may be at a disadvantage when disputing DNA evidence.27 The unequal distribution of resources in criminal defence contributes to potential miscarriages of justice, particularly for the poor.
4. Potential for Misuse and Data Security
The risk of misuse of DNA evidence is a growing concern, particularly in the digital age. Unauthorized access to DNA databases, whether by hackers or rogue state actors, can lead to breaches of personal privacy. 28 DNA profiles contain detailed genetic information that goes beyond mere identification; they can reveal sensitive data about an individual’s ancestry, medical conditions, and predispositions to certain diseases. Legal framework protects the individual rights. Many countries are still grappling with how to create robust laws governing DNA evidence, ensuring that data security is prioritized while allowing for the continued use of DNA in solving crimes. 29 25.

CASE STUDIES
1. R v. Colin Pitchfork (1987, UK)
Colin Pitchfork was convicted for rape case in the United Kingdom. In 1986, two teenage girls, Lynda Mann and Dawn Ashworth, were raped and murdered in the small town of Narborough. Investigators initially arrested another local man based on witness testimony, but when DNA testing was conducted on samples collected from the crime scene, the results excluded him as the perpetrator. To find the real criminal, police conducted the world’s first mass DNA screening, testing over 5,000 local men. Pitchfork initially avoided detection by persuading a colleague to submit a DNA sample on his behalf. However, the colleague later confessed, leading to Pitchfork’s arrest. His DNA was tested and matched the samples from the crime scenes, resulting in his conviction.
This case was the first DNA evidence used to both exonerate an innocent suspect and convict the actual perpetrator, demonstrating the power of genetic profiling in criminal investigations. 30
2. The People v. O.J. Simpson (1995, US)
The most publicized criminal trials in U.S. history, DNA evidence played a crucial role in the prosecution of O.J. Simpson accused for murdering his ex-wife Nicole Brown Simpson and her friend Ronald Goldman. The prosecution presented DNA evidence linking blood samples from the crime scene to Simpson, with DNA analysis showing a match to blood found on a glove at the crime scene and in Simpson’s car. The court raised questions about the reliability of DNA evidence when the forensic protocols are not followed properly as handling and integrity was challenged. Despite the overwhelming scientific evidence, Simpson was acquitted, largely due to the defence’s ability to cast doubt on the prosecution’s forensic procedures. This case highlighted the importance of proper collection and preservation techniques, emphasizing that DNA evidence alone is not infallible if mishandled.3

3. The Innocence Project: People v. Steven Avery (2003, US)
Steven Avery’s case exemplifies how DNA evidence has been instrumental in exonerating wrongfully convicted individuals. Avery was prisoned for 18 years for sexual assault in 1985. Throughout his sentence, he maintained his innocence. In 2003, the Innocence Project, a nonprofit legal organization focused on overturning wrongful convictions, took up Avery’s case. DNA testing, which was not available at the time of his original trial, was performed on the evidence from the crime scene. The results excluded Avery as the perpetrator and identified another man who had a history of sexual assault convictions. Avery was subsequently exonerated and released from prison. This case demonstrated the transformative role DNA evidence can play in post-conviction settings, correcting miscarriages of criminal justice and offering freedom for the wrongfully imprisoned.32
4. State of Gujarat v. Kishanbhai (2014, India)
In this Indian Supreme Court case, DNA evidence was pivotal in reversing a wrongful conviction. Kishanbhai was accused of kidnapping and murdering a young girl, the lower courts convicted him based on circumstantial evidence. Upon appeal to the Supreme Court, it was argued that the forensic evidence, including DNA analysis, had not been properly examined during the trial. The court ordered a review of the forensic evidence, which included DNA testing that had initially been disregarded. The results showed no match between the crime scene evidence and Kishanbhai, leading to his acquittal. This case underscored the importance of forensic evidence, especially DNA testing, in ensuring justice. It also highlighted the need for proper forensic practices to avoid wrongful convictions in the Indian legal system.33

5. Golden State Killer Case (2018, US)
In this case, Joseph James DeAngelo was responsible for a series of rapes and murders in California in the 1970s and 1980s, eluded police for over 40 years. In 2018, investigators used a novel approach by uploading DNA from the crime scenes to a public genealogy database, identifying relatives of the perpetrator through familial DNA. This led to the arrest of Joseph James DeAngelo, whose DNA profile matched evidence from the crime scenes. The use of genealogy databases to identify criminals opened a new chapter in forensic science, offering a powerful tool for solving cold cases. However, it also raised significant ethical questions regarding privacy and the use of public DNA databases for criminal investigations.34
FUTURE DIRECTIONS AND CHALLENGES
The future of DNA evidence in the criminal justice system has a significant advancement, but it also faces numerous challenges that needs to be addressed. As forensic technologies evolve, the potential for more accurate and comprehensive DNA analysis will increase, which could enhance the reliability of evidence in criminal investigations. 35 Emerging techniques such as Next Generation Sequencing (NGS) are expected to provide deeper insights into complex DNA samples, enabling forensic scientists to resolve cases that previously lacked sufficient genetic material. This technological progress will likely allow for the analysis of degraded or mixed samples, which are common in criminal cases. 36 Additionally, the development of portable DNA analysis tools may revolutionize crime scene investigations by allowing for on-site testing.
Rapid results could expedite the investigative process, facilitating quicker decision-making by law enforcement and potentially leading to timely interventions. There are significant challenges that must be addressed.

Privacy concerns are paramount, especially as DNA databases expand. Issues surrounding the collection, retention, and potential misuse of genetic data have raised ethical questions that must be carefully considered. The potential for surveillance and racial profiling based on DNA evidence presents a risk of exacerbating existing biases within the criminal justice system. 37 Furthermore, the legal frameworks governing DNA evidence must evolve to ensure they adequately protect individual rights while allowing law enforcement to effectively utilize these powerful tools. Establishing clear guidelines for the admissibility of DNA evidence, particularly regarding emerging technologies, will be essential in maintaining the integrity of the judicial process.
In summary, while the future of DNA evidence in criminal justice is bright, it necessitates a careful balance between technological advancement, ethical considerations, and legal protections. Stakeholders, including policymakers, law enforcement, and forensic scientists, must work collaboratively to address these challenges to ensure that the use of DNA evidence remains a reliable and just component of the criminal justice system. 38
CONCLUSION
The integration of DNA evidence into the criminal justice system has marked a significant advancement in forensic science, enabling more accurate identification of suspects and the exoneration of wrongfully convicted individuals. Its unique ability to provide precise genetic information has not only enhanced investigative processes but has also contributed to resolving cold cases that remained unsolved for years. However, the widespread use of DNA evidence brings forth critical legal and ethical considerations that must be navigated carefully. Issues related to privacy, the potential for misuse of genetic data, and the need for equitable practices in DNA collection and storage underscore the importance of establishing robust legal frameworks. 37.
