In light of this, Computer Forensic Specialists employ state-of-the-art tools and methodologies in the extraction and analysis of data from storage devices used at the digital cri...

In this paper, the concept of distributed cognition is used to inform the design, development and trialling of technologies to support Crime Scene Examination is reported. A user trial, with trainee Crime Scene Examiners, was conducted to compare the ways in which evidence search and recovery could be combined with the production of a crime scene report (that must be written at the scene).
