Digital forensics has become an indispensable component of modern criminal investigations, fundamentally transforming how law enforcement agencies gather and analyze digital evidence. This discipline encompasses the processes of searching, acquiring, preserving, and analyzing digital content to solve crimes and ensure justice is served. As digital footprints continue expanding across personal devices, social media platforms, and cloud services, digital forensics provides crucial insights into criminal activities that would otherwise remain undetected.

The significance of digital forensics is underscored by its extensive application across diverse criminal cases, ranging from cybercrimes to traditional physical crimes involving digital evidence. A notable example is the case of Mikayla Munn in 2016, where digital forensic techniques played a pivotal role in uncovering critical evidence. Munn, a former student at the University of Manchester, secretly kept her pregnancy concealed and ultimately drowned her newborn in a bathtub. Her initial claim was ignorance of her pregnancy, but subsequent digital investigations revealed a different story. Forensic analysis of her electronic communications uncovered texts to acquaintances indicating awareness of her pregnancy, and internet searches for "at home abortions" and "methods to cut the umbilical cord" provided further evidence of premeditated intent (Karie, Kebande, & Venter, 2016). This digital trail led to her conviction and served as concrete evidence in her trial.

This case exemplifies the critical role digital forensics plays in corroborating eyewitness statements, uncovering hidden motives, and establishing timelines. The forensic process entailed extracting data from mobile phones, analyzing message histories, and understanding internet search histories—each step contributing to constructing a detailed narrative of the events. The autopsy findings, which indicated the baby had taken a breath after birth before drowning, coupled with digital evidence, painted a more comprehensive picture of the incident.

The process of digital forensic investigation involves several key steps. First is the identification of digital devices and sources that may contain relevant evidence. These include computers, smartphones, tablets, and cloud storage. Next is the acquisition of digital data, where investigators utilize specialized tools to create forensic images that preserve the integrity of original data. Preservation follows, ensuring that chain-of-custody protocols are maintained to prevent tampering or data loss. Analysis involves sifting through the acquired data using various software tools to identify relevant evidence such as texts, images, emails, or internet searches. Reporting then consolidates findings into a comprehensible format for presentation in court.

Despite its crucial importance, digital forensics faces several challenges. The rapid evolution of technology leads to diverse data formats and encryption methods that complicate access and analysis (Quick & Choo, 2016). Increasing reliance on cloud computing spreads data across multiple jurisdictions, raising jurisdictional and legal concerns. Additionally, the volume of data—sometimes referred to as “big data”—poses issues of storage, processing speed, and relevance filtering, making investigations resource-intensive (Choo, 2016).

Another challenge lies in ensuring forensic soundness—meaning that evidence has not been contaminated or altered throughout the process. To mitigate this, investigators must follow strict protocols and maintain detailed logs of each step. Furthermore, cybercriminals employ anti-forensic techniques, such as data obfuscation and encryption, complicating efforts to recover meaningful evidence. As technology advances, so too must forensic tools and methods, requiring continuous training and development within the field.

Legal and ethical considerations also play a pivotal role in digital forensics. Privacy rights must be balanced against investigative needs, especially when accessing personal information stored in private clouds or IoT devices. Legal frameworks vary across jurisdictions, necessitating investigators to be knowledgeable about applicable laws to ensure admissibility of evidence (Karie et al., 2016). Furthermore, safeguarding victim rights and handling sensitive information with confidentiality is fundamental to uphold justice.

In conclusion, digital forensics is a vital component of modern criminal investigation, providing a scientific basis for uncovering digital evidence that can decisively influence case outcomes. Its application in cases like Mikayla Munn’s demonstrates its power to reveal hidden truths and support judicial processes. However, the field faces ongoing challenges due to rapid technological change, legal complexities, and the volume of digital data. Continued advancements in forensic tools, legal frameworks, and investigator training are essential to overcome these hurdles and ensure the effectiveness of digital forensics in the pursuit of justice.
