Digital crime scenes take place in the context of physical crime scenes. Virtual crime scene reconstruction is an activity where investigators create a 3dimensional (3-D) model of an actual crime scene for the purpose of determining the events that lead to the crime. While virtual crime scene reconstruction is currently used for analyzing physical scenes, it can also help investigators visualiz...

With the advent of Information and Communication Technologies, the means of committing a crime and the crime itself are constantly evolved. In addition, the boundaries between traditional crime and cybercrime are vague: a crime may not have a defined traditional or digital form since digital and physical evidence may coexist in a crime scene. Furthermore, various items found in a crime scene ma...

Criminal traces commonly found at crime scenes may present mixtures from two or more individuals. The scene of the crime is important for the collection of various types of traces in order to find the perpetrator of the crime. Thus, we propose that hematophagous mosquitoes found at crime scenes can be used to perform genetic testing of human blood and aid in suspect investigation. The aim of th...

To determine the circumstances of an incident, investigators need to reconstruct events that occurred in the past. The large amount of data spread across the crime scene makes this task very tedious and complex. In particular, the analysis of the reconstructed timeline, due to the huge quantity of events that occurred on a digital system, is almost impossible and leads to cognitive overload. It...

While most individuals and businesses use the Internet as a communication medium to learn and to socialize, other individuals and groups use the Internet as a medium for criminal purposes. The Internet has positively transformed many legitimate business activities, lowering costs and accelerating transaction speed. It has also served as a platform for criminals who strategize online and attack ...

The detection of latent traces is an important aspect of crime scene investigation. Blood stains on black backgrounds can be visualized using chemiluminescence, which is invasive and requires a darkened room, or near-infrared photography, for which investigators need to change filters manually to optimize contrast. We demonstrated the performance of visible reflectance hyperspectral imaging (40...

The purpose of this study was to measure the team skills of operational crime scene examiners (CSEs). The techniques used were based on established methods and helped to gain a greater understanding of the domain of forensic investigation. The research begins with a hierarchical task analysis and then adapts pre-established methods for measuring the performance of CSEs in four UK Police Forces....

Underwater crime scene investigation and emergency response are tasks typically carried out by divers constituting part of a specialist team. Operating in such dynamic environments, often with poor visibility risk concealed hazards, can be time consuming dangerous. Autonomous uncrewed vessels underwater acoustic imaging sensors have been used for similar purposes other fields (e.g., hydrography...
