This paper proposes some new techniques for the development of virtual 3D environments for crime scene reconstruction. Current techniques were investigated, which concentrate on the production of photo-realistic scenes. However, these were considered to be too specialist and expensive. The Crime Scene Creator developed here provides a cheaper and quicker alternative that allows quasiaccurate sc...

Event reconstruction plays a critical role in solving physical crimes by explaining why a piece of physical evidence has certain characteristics. With digital crimes, the current focus has been on the recognition and identification of digital evidence using an object's characteristics, but not on the identification of the events that caused the characteristics. This paper examines digital event...

We developed Cyber Forensics Ontology for the criminal investigation in cyber space. Cyber crime is classified into cyber terror and general cyber crime, and those two classes are connected with each other. The investigation of cyber terror requires high technology, system environment and experts, and general cyber crime is connected with general crime by evidence from digital data and cyber sp...

This study is to propose a fully automatic crime scene shoeprint retrieval algorithm that can be used to link scenes of crime or determine the brand of a shoe. A shoeprint contour model is proposed to roughly correct the geometry distortions. To simulate the character of the forensic experts, a region priority match and similarity estimation strategy is also proposed. The shoeprint is divided i...

Amylase testing has been used as a presumptive test for crime scene saliva for over three decades, mainly to locate saliva stains on surfaces. We have developed a saliva screening application for crime scene trace swabs, utilising an amylase sensitive paper (Phadebas(®) Forensic Press test). Positive results were obtained for all tested dried saliva stains (0.5-32 μL) with high or intermediate ...

We study the problem of forensic identification when the trace evidence from the scene of the crime is imperfect: for example, it might be measured with error, or be partially missing. A general framework for imperfect data is developed, and applied in particular to the following cases, singly and in combination: 'measurement error' in the recorded information at the scene of the crime; 'binnin...

AbstractDuring the years 2000 to 2020 Department of Forensic Medicine at University Southern Denmark performed 293 medical crime scene investigations in involving 320 deceased (200 men). The examiner was called out homicides (24%), suspicious cases (58%), fire related deaths (15%) and bone findings (2%). responsible for examination corpses cooperation with technicians. goal determine cause deat...
