Advances in Technologies in Crime Scene Investigation

Area of Science:

• Forensic Science
• Digital Forensics
• Medical Imaging

Background:

• Crime scene investigation (CSI) is crucial for reconstructing criminal events, yet often challenging for forensic pathologists.
• Unsolved cases highlight the need for advanced techniques to accurately analyze crime scenes.
• 3D scanning technology offers improved capabilities for detailed, large-scale spatial data acquisition.

Purpose of the Study:

• To evaluate the utility of laser scanning (LS) technology in forensic pathology and crime scene investigations.
• To assess how LS impacts the reconstruction of crime dynamics and the resolution of judicial cases.

Main Methods:

• Retrospective analysis of crime scene investigations conducted between January 2019 and June 2022.
• Inclusion criteria: use of laser scanner (LS), camera, full scene data, and judicial police collaboration.
• Exclusion criteria: cases without LS utilization.

Main Results:

• Laser scanning facilitated rapid creation of scale plans for crime scenes, aiding swift case progression.
• LS applications included clarifying suicidal intent in fall cases, reconstructing historical scenes, and differentiating suicide from homicide.
• LS was instrumental in planning COVID-19 pathway studies within hospitals to reduce nosocomial transmission.

Conclusions:

• Laser scanning technology significantly enhances forensic staff's ability to crystallize and analyze investigative scenes.
• LS proves to be a valuable tool for improving the accuracy and efficiency of crime scene investigations.
• The integration of LS supports the resolution of complex judicial cases and diverse forensic applications.
