The world over, it is indisputable that the introduction of computer technology in different facets of life, has virtually transformed and entranced information processing, which is very vital in any organization or parastatals of government.  Not only as a means of information processing, has the technology also proved to be the fastest means of information retrieval, which forms the nucleus of this study
    This work tries to x- ray the rate role of the computer in case filling system for drug monitoring Agency. It looks at ways of improving the information management of the Agency.  This research work will cover the following areas: record information retrieval relating to MIS (Management information system),  and crime mapping through a data bank of crime related information.
    A detailed design of a computerized approach that will bring the much needed innovation is given.  Also included in this work is paper documentation for the new system design.
