It is an experimental approach to aid the process of investigating crime by treating cases and subjects of the case as the nodes that might be linked to each other using DNA matching. The relation between the subjects of the cases and cases itself is defined by their DNA frequency and likelihood ratio. DNA TRACERS analyze each cases and subjects using non-linear method to further improve investigation by finding any possible relation between distinct cases, which is not implemented as an automated process in current practice. These relations are depicted in the form of graphical diagram which is easy to interpret by end-user. Statistical graph and score table for convicted offenders is calculated based on several criteria. It is provided in order to support the process of decision making. Mechanism procedure in DNA TRACERS made it possible to separate between forensics unit and investigative unit as different entities. Both entities are working together to solve cases with controlled access to their authorized database. DNA TRACERS support structured data format for casework, case subject and case analysis record. Built in security and strict data transfer control is implemented to ensure the integrity of the system and subsystems. Generated report automation with standardize format will become easier for different investigative unit do collaboration to solve crime investigations</p> https://www.ultrascientist.org/paper/1289/ case chain computer-aided investigation DNA analysis DNA TRACERS forensic investigation.
