- Apr 2, 2025
- Latest Journal
As technology evolves at an ever-increasing pace, so too do the opportunities and challenges for the criminal justice system. Digital evidence has become an essential component in most modern criminal investigations, with forensic investigators playing a vital role in ensuring that justice is served. In this article, we will explore the services provided by digital investigation specialists, the challenges of managing digital evidence, and the crucial role these experts play in criminal justice today.
Digital Investigations: An Overview
Digital investigations have come a long way since the early days of digital forensics, where the primary focus was on extracting data from physical devices like computers and mobile phones. While traditional digital forensics still plays a crucial role in gathering “dead box” data from devices, the field of digital investigation has broadened to cover a much wider spectrum of services. These include cell site and Wi-Fi analysis, social media intelligence, GPS investigations, and vehicle telematics.
At IntaForensics, we have embraced this evolution, offering a comprehensive digital investigation service. Our team builds on more than 16 years of experience, working across a wide range of criminal justice cases. Our digital investigators are specialists in extracting and analysing digital data in ways that provide new insights and lines of enquiry for investigations.
The difference between digital forensics and digital investigation lies not only in the tools used but also in the approach. While digital forensics traditionally focuses on retrieving static data from devices, digital investigation considers live data and context, allowing investigators to pursue dynamic leads that can support or refute key elements of a case.
The Growing Importance of Digital Evidence
In today’s world, digital evidence is pervasive. The majority of us now carry smartphones and are constantly connected to the internet, leaving digital footprints everywhere we go. For criminal investigations, this provides a treasure trove of information that, when analysed properly, can reveal crucial details about a person’s movements, actions, and communications.
Digital evidence comes in many forms: GPS data from a vehicle or smartphone can reveal where a suspect was at a specific time, while social media activity can provide insights into a suspect’s state of mind or even contradict alibis or witness statements. Similarly, communications on platforms like WhatsApp, Snapchat, and Telegram can prove pivotal in cases ranging from fraud to serious violent crime.
For example, one of our cases involved the use of social media in a sexual assault investigation. The prosecution presented screenshots from a Tinder account that appeared to show incriminating chat logs. However, the defendant denied ever using Tinder. Upon reviewing the digital evidence, our team found that no formal request had been made to Tinder to verify the account information, such as email addresses or IP logins. Screenshots alone were not sufficient to definitively link the defendant to the account, and our analysis demonstrated the need for more thorough digital attribution before reaching a conclusion.
Navigating the Challenges of Digital Investigations
While digital evidence can be incredibly powerful, handling it properly is key. One of the significant challenges in digital investigations is the complexity of the data. Unlike traditional forensic evidence, which might involve physical traces such as fingerprints or DNA, digital data often exists in massive quantities and is constantly changing.
Mobile phones, for example, generate and store a tremendous amount of information. However, analysing that information and drawing meaningful conclusions from it requires both technical expertise and a deep understanding of the context in which it was generated. Additionally, as the capabilities of digital devices expand, the amount of data that can be extracted also grows exponentially. Investigators must ensure they have the right tools and techniques to manage this influx of data.
At IntaForensics, our team handles a wide range of digital evidence. This includes communications data analysis, which can track calls, text messages, and data usage across mobile networks. Our investigators are adept at analysing this data in conjunction with cell site and Wi-Fi analysis to pinpoint a suspect's location or activity. This can be crucial in establishing or undermining alibis, particularly in cases where location data is key.
We also routinely conduct open-source intelligence (OSINT) gathering, which involves the analysis of publicly available data on the internet, including social media platforms. Often, people post comments, share information, or engage in conversations on public platforms without realising that this information could later become relevant in a criminal investigation. Our ability to analyse and interpret these digital footprints has proven invaluable in numerous cases.
Real-World Case Studies
To illustrate the power of digital investigations, it’s worth considering some real-world examples where our expertise has played a pivotal role.
In one case, a defendant was accused of sending racially charged messages on Twitter (now X) and possessing an illegal publication. The prosecution relied heavily on the Twitter posts, some of which were protected tweets, meaning they were only visible to select followers. Our role was to explain the mechanics of Twitter to the court, including the distinctions between public and private posts, and to verify whether the account in question could be linked to the defendant. Additionally, we reviewed the alleged illegal publication, only to find that it was readily available on major online platforms like Amazon, undermining the claim that it was an illegal item. This insight from our report proved crucial in questioning the reliability of the evidence presented by the prosecution.
Another fascinating case involved the investigation of vehicle telematics. A young driver was charged with causing death by reckless driving. The key evidence was the location data retrieved from the driver’s iPhone, which provided detailed GPS coordinates throughout the journey. Using specialised software, our experts were able to map the journey, calculate the driver’s speed, and determine that excessive speed was indeed a factor. The same technology, however, can also be used to exonerate drivers in other cases, demonstrating the importance of digital analysis in determining the truth.
The Digital Media Investigator: A Critical Role in Law Enforcement
The role of the Digital Media Investigator (DMI) has evolved significantly in recent years, reflecting the growing importance of digital evidence in criminal investigations. However, the structure of DMI teams varies widely across law enforcement agencies. In some forces, DMIs are full-time specialists, while in others, officers juggle the DMI role with their regular duties in areas such as CID or major crime units. This variability in training and experience can result in gaps in digital evidence handling, with some DMIs receiving only limited training yet being asked to provide crucial evidence in serious cases.
At IntaForensics, our digital investigators are highly trained specialists, many with extensive experience in law enforcement. They not only gather digital evidence but also provide expert testimony in court, ensuring that complex digital data is presented in a clear and comprehensible manner. This is especially important in cases involving communications data or social media analysis, where the technical intricacies can be challenging for juries to understand.
One of the key roles of a digital investigator is ensuring proper attribution. In cases where digital evidence is used, it is essential to establish that the data belongs to the person in question. For instance, in social media cases, it is not enough to simply present a screenshot of a message or post. Investigators must be able to demonstrate that the account in question is controlled by the suspect and that no third party could have accessed it. This often involves analysing IP addresses, multi-factor authentication methods, and call data records.
Staying Ahead in a Rapidly Evolving Field
Digital investigation is an ever-evolving field, with new technologies and platforms emerging all the time. Staying ahead of these changes is essential for investigators. At IntaForensics, we continually update our knowledge and skills to ensure we can tackle the latest challenges. For example, we are frequently asked to examine new mobile applications like Telegram or TikTok, which may not have existed just a few years ago but are now central to certain criminal investigations.
Moreover, modern vehicles have become a new frontier for digital evidence. Many vehicles now store vast amounts of data related to their location, speed, and even driver behaviour. In cases involving vehicular crimes, such as dangerous driving or hit-and-run incidents, this data can provide a clear picture of what happened at the time of the incident. Our experts have the tools and expertise to extract and analyse this data, providing critical evidence for both prosecution and defence teams.
Expert Witness Testimony and Consultancy
In addition to providing investigative services, our digital investigators are frequently called upon to serve as expert witnesses in court. The ability to clearly explain complex digital evidence to a judge and jury is a crucial part of ensuring that justice is done. Whether it’s explaining the intricacies of cell site analysis, the behaviour of social media applications, or the operation of vehicle telematics, our experts ensure that digital evidence is presented in a way that is both accurate and understandable.
We also offer consultancy and training services to law enforcement and public sector agencies. Our training programmes are designed to enhance digital awareness and ensure that those working in the criminal justice system are up to date with the latest developments in digital evidence. These courses can be delivered online or in person and are tailored to the specific needs of the client.
