ABSTRACT

In forensic cases, for a mechanical digital reconstruction can be helpful to constrain a set of postures and velocities at the start of a fall from a high height. The simulations illustrate the possible trajectories and movements of the body in descent. This information is critical to confirm, refine, or change the cause hypothesis in incidents. This article shows the utility of a virtual dummy to simulate different initial conditions of a specific case fall from a three-story building. The best-input parameters produce the maxima congruence with the final posture and fractures, which only occurred on the left side of the body. Thus, a forward run of 5 m/s and a little interaction with the branches of a nearby tree at jumping were enough factors to cause a dynamic that ended with the final posture of the body (tall: 1.69 m, mass: 50 kg) at a horizontal distance of 7.78 m and vertical 12.5 m from the origin coordinates. The complete analysis demonstrates the potential of numerical simulations as a tool in forensic investigations of falls.
