The combination of features from the convolutional layer and fully connected a neural network (CNN) provides an effective way to improve performance crime scene investigation (CSI) image classification. However, in existing work, as weights feature fusion do not change after training phase, it may produce inaccurate which affect classification results. To solve this problem, paper proposes adap...

This paper is focused on two main topics: crime scene reconstruction, based on a geomatic approach, and crime scene analysis, through GIS based procedures. According to the experience of the authors in performing forensic analysis for real cases, the aforesaid topics will be examined with the specific goal of verifying the relationship of human walk paths at a crime scene with blood patterns on...

OBJECTIVE The strategies of novice and expert crime scene examiners were compared in searching crime scenes. BACKGROUND Previous studies have demonstrated that experts frame a scene through reconstructing the likely actions of a criminal and use contextual cues to develop hypotheses that guide subsequent search for evidence. METHOD Novice (first-year undergraduate students of forensic scien...

Three categories of crime-scene behaviors (violence, interpersonal involvement, and criminal sophistication) among a group of 22 serial and 22 single-victim rapists were studied. Findings indicate that serial rapists were more likely to display a higher level of criminally sophisticated behaviors to avoid detection, whereas single-victim rapists were more likely to behave violently and engage i...

Tracheo-brachiocephalic artery fistulas were rarely reported lesions often described in cases with tracheostomy procedures. Reported case was 26 year-old male drainage worker, trapped under the stony soil while excavating drainage canal. Rescue operation was performed, but he was reached dead. Provincial prosecutor mandated autopsy after crime scene investigation. Autopsy examination revealed t...

Crime scene investigation requires teamwork; therefore, those involved in this process should know their duties and responsibilities very well. First responders are among the most important responsible group of personnel. Contrary to crime team or expert laboratory personnel, first do not technically examine available evidence at but protect by keeping chaotic environment under control scene. &...

Body fluid traces recovered at crime scenes are among the most important types of evidence to forensic investigators. They contain valuable DNA evidence which can identify a suspect or victim as well as exonerate an innocent individual. The first step of identifying a particular body fluid is highly important since the nature of the fluid is itself very informative to the investigation, and the...
