I 4 Research Methodology This dissertation is a qualitative research with two methods of study. It involved interviews with Crime Scene Analysts and Offender Profilers. This method provided first hand and up to date information on the different approaches to offender profiling. The standard legal research method of case analysis has also been used. This involved extensive case analysis. Cases that involved offender profiling have been analyzed. This method provided adequate background information on the admissibility problems of offender profiling evidence. The limitation to this dissertation is the unwillingness of some profilers to grant interviews and share their knowledge. 5 ~...................... --------- Abstract This dissertation examined the use of offender profiling evidence in criminal cases.

Who is qualified to give expert profiling evidence? Is offender profiling too prejudicial than probative? Is offender profiling an opinion on the ultimate issue? Is offender profiling sufficiently reliable as to be admissible? This dissertation has noted that in United States, there are inconsistencies in the court decisions on offender profiling evidence as a result of the three conflicting rules governing the admissibility of expert evidence. After a critical examination of the three rules, the adoption of one rule has been suggested. The Frye test standard combined with the Federal Rules of Evidence 702 provides the best admissibility standard. Many people are confused as to the appropriate discipline of offender profiling. This dissertation has therefore, presented a step by step analysis of the history and development of offender profiling. Offender profiling is a multi-disciplinary practice that cuts across many disciplines. At the moment, it is best described as an art with the potential of becoming a science. This dissertation concludes that offender
