The forensic identification technician acts as an expert in this field. He supports investigations in order to help solve crimes. He visits the crime scenes that require his expertise in order to gather incriminating evidence or evidence necessary to discover any clue that explains the crime committed and the identification of suspects in connection with the crime. He takes the appropriate steps to preserve and conserve the evidence collected.
Based on analysis of the evidence, comparison of fingerprints, DNA samples and other information, he specifies, beyond reasonable doubt, that a person was present on the crime scene.
