Criminal Investigation Research System

Abstract

Presently Sri Lanka Police Department handles the criminal investigation process in Sri Lanka. It requires a lot of criminal information island wide to carry out investigations and decision-making. Existing process is manual and consumes a lot of time, human resources and has many drawbacks as well. It is not easy to handle a manual system with the increase of crimes island-wide.

There are international projects for criminal justice systems around the world such as FBI, Scottish Criminal Justice System, Colorado etc. These systems use ICT for criminal investigation effectively and explained in the Project Background chapter later.

The main objective of the research project is to propose a solution for criminal investigation process in Sri Lanka with the use of ICT. The new solution is called as “Criminal Investigation Research System (CIRS)”. Project category is IT Research Project and it’s an e-government project. Scope of the project are processes at CRD, regional police station crime inform/retrieval, criminal justice organization crime information/retrieval, crime information browsing and reporting facility to relevant authorities.

New solution will be a web based user-friendly solution. It enhances the existing process with ease of information record keeping, retrieval, sharing with other criminal justice organizations, decision making, connecting regional police stations etc. It is to be implemented in 4 phases. It uses N-tier web architecture with database and servers

This thesis covers related literature review, solution framework, design strategies, implementation strategies, and evaluation. of the CIRS project. Proposed solution framework has been implemented using prototype at Police Department. CIRS may be the new revolution to the criminal investigation process in Sri Lanka. It can be used as a backbone and guide for other criminal justice organizations such as court, prison, and armed forces to integrate their systems with out duplicating information in future.
