Law Enforcement Case Study - Indecent Images - Computer Analysis

The following is an anonymised case study based on a real assignment conducted by CCL-Forensics for a Law Enforcement Agency

Police were informed by a cleaner working for a large company that they had found printed indecent images in the office of the suspect.  The Police investigation began and the suspect’s computer was delivered to CCL-Forensics Ltd for analysis.

The suspect had already stated that they had an alibi for a certain period of time as they had lent their computer to a friend. The investigation therefore focused on dates surrounding this period so that any evidence could be linked to that particular suspect.

CCL analysts found that the source of the printed pictures discovered in the office could have actually been when the computer was used the previous year (outside the period that the suspect had an alibi). Our analysts also discovered that software had been used to try to erase the images, however, string text and partial images were discovered in unallocated space. This evidence was enough to charge the suspect with the possession of indecent images.
