Forensic Physics and Ballistics
The Center for Forensic Physics/Ballistics performs dynamic reconstructions of crime scenarios involving firearms and those involving a sharp instrument or blunt force. Our work also includes investigating the level of danger when persons have objects thrown or shot at them or are beaten with objects, and the level of danger associated with "non-lethal" weapons and devices.
Close collaboration with the Department for Forensic Medicine and Imaging makes it possible to produce interdisciplinary assessments combining spatial, forensic, physical and clinical findings. The Center for Forensic Physics/Ballistics operates across Switzerland and abroad and often collaborates with various forensics services and institutes of forensic medicine based in other cantons.
Forensic physics is concerned with investigating the effects of blunt force on humans or forces produced by sharp instruments. Various procedures are used to investigate the phenomena encountered during practical forensics work:
- The danger level when persons are beaten with objects or have them thrown at them can be investigated by measuring the energy involved during beating or throwing.
- The level of danger (in mechanical terms) associated with jets of liquid such as pepper spray can be determined via pressure measurements and high-speed photography.
- A drop tower makes it possible to reconstruct puncture and impact scenarios.
- In collaboration with the mechanical workshop, a wide range of scenarios can be recreated in order to reconstruct a particular case.
- The level of danger associated with blast incidents can be determined via blast pressure measurements.
