Forensic Detectives

Electronic Witness examines how modern technology—mobile phones, CCTV and cashpoints—can be used to crack murder investigations. The programme demonstrates the practical ways these tools help detectives identify suspects, track movements and gather crucial evidence.

Electronic Witness is a television episode that looks at the role of modern technology in criminal investigations. The programme presents a concise overview of the ways digital tools are employed by law‑enforcement agencies when a homicide needs to be solved. It’s formatted as an informative segment rather than a drama. The core of the episode examines how devices such as mobile phones, closed‑circuit television and cashpoint machines can be harnessed to crack murder cases. By highlighting the practical application of these tools, the show demonstrates that contemporary investigations increasingly rely on electronic data to piece together what happened. Mobile phones are shown as a key source of information, offering location records, call logs and messaging history that can place suspects at specific times and places. The episode points out that these digital footprints often provide the first leads for detectives, turning a simple device into a vital piece of evidence. CCTV footage and cashpoint transaction records are also featured as essential resources. Surveillance cameras can capture visual evidence of movements around a crime scene, while cashpoint logs can reveal financial activity linked to individuals of interest. Together, these technologies give investigators a broader picture, helping to narrow down suspects and build a case. This combination of data points often proves decisive in bringing perpetrators to justice.
