PROTOCOL FOR ANALYSIS OF CASES OF LOST BALANCE THROUGH MEDICAL IMAGES AND QUICK PROTOTYPAGE
In Brazil, the number of cases of missing bullets and the number of cases filed for lack of evidence are very high. Criminal expertise requires official protocols that validate evidence from forensic technologies. The objective of the research was to analyze two cases involving children affected by stray bullets. Computed tomography and nuclear magnetic resonance imaging were reconstructed in 3D with the Navegatium and InVesalius free software. The intracorporeal trajectory of each projectile was estimated as well as tissues damaged by trauma. Models of these structures can be printed by additive manufacture to provide more detail about the trajectory of the bullets. The results of this study can be used in biomechanical analysis based on the physical properties of the tissues reached to estimate the location of the shooter.

Forensic science seeks to find solutions in legal cases such as explaining accidents and crimes. Most of the time it is necessary to determine the identification or characteristics of an individual from the remains of the same. Such identification is based on the use of regression equations generated from a sample of skeletons. These equations establish the relation between two variables so that one can be estimated from another available. Brazil still does not have a database with accurate measurements of anthropometric parameters of its population. Such data are fundamental for the development of forensic studies in the area of biomechanics. The objective of this research is 1) To create a database of parameters of the hands of a population of São Paulo and 2) To carry out regression analysis of these measures to generate an equations that can estimate the height of a person to give birth of measures of the hands. The applicability of the use of regression equations found in the forensic literature for the estimation of height from hand measurements will be investigated. The research aims to generate a new group of equations that are more adequate for the identification of individuals of a Brazilian population.

CREATION OF A BASE OF HAND AND STATUS DATA FOR GENERATION OF REGRESSION MODELS IN FORENSIC ANTHROPOMETRY
CREATION OF A PROTOCOL FOR SIMPLIFIED 3D RECONSTRUCTION OF GUN VITIMES.
The research is the result of institutional collaboration between the Center for Anthropology and Forensic Archeology CAAF of UNIFESP and the Latin American Center of the University of Oxford. The project "State Violence in Brazil: An Analysis of the May 2006 Crimes from the Perspective of Forensic Anthropology and Transitional Justice" aims to consolidate the area of Forensic Anthropology in Brazil from transitional justice initiatives that occur from the end of dictatorship. The objective of this part of the research is to create protocols for the 3D reconstruction of 4 cases of firearm deaths that occurred in the May 2006 event in Baixada Santista in the state of São Paulo. The free software MakerHuman and Blender are being used to create avatars with qualitative 3D reconstructions of crime scenes from information from police bulletins and expert forensic reports. The protocols created will be validated and the possibility of implementation in legal proceedings will be investigated.
