Photographic surveying is fundamental to crime scene investigation. It is performed using 2D images; however, this method islimited because it does not offer a detailed view. We present a 3D (three-dimensional) experimental model that has clarified unsolved aspectsof a homicide. A woman was found dead in her home. Considering the large number of injuries on the victim, signs of the use of two weap-ons, and the absence of traces of the killer/s, several hypotheses about the dynamics and the number of offenders were made. The forensic sur-veys suggested that a single offender had used two weapons at the same time, but this hypothesis was considered to be impossible byinvestigators. Our 3D model allowed us to experimentally reproduce the murder and compare various dynamics. The model was used as evi-dence in Court to prove the hypothesis of a single killer and demonstrate that no other people were involved.
