Abstract

Criminal Profiling Investigation on the basis of criminal behavior distinction Analysis in crime scene have increased in recent year, and this is useful high. But there is on children missing(or kidnapping) only victim, that is not useful. Fortunately, empirical study findings according to interview of offenders show that they similar/same M.O. feature per criminal as though they are same people do that. And that results are very useful in child-kidnapping-sexual assault murder investigation. For comparison on result of external cases, I examine internal child-kidnapping-sexual assault and murder cases. In order to make up for the mistake of hasty generalization due to lake of the cases, I search cases of molesting children under 13, pay attention that they have sexual motive for children. The result of internal child-kidnapping-sexual assault and murder cases were similar/same M.O. with pre, in, and post crime, as external cases. In short, most of crime victim is ordinary children and they(victim and criminal) met by chance on the street. Criminal get their victim using flirt with victim or ask for help. And right after kidnapping, they had binding and control victim using excessive assault, they are just children although not necessary control. And they kidnapped for main desires, sexual drive. But they killed victim by rational reason, differ from external murder caused by sex motive happened like a serial scenario. Post crime, most of body was dismembered and abandoned. Except survival victim fortunately, body finding point marked a watershed in internal child-kidnapping-sexual assault-murder investigation. And then criminal was arrested in about 3days. Otherwise offender of children under 13 differs from child-kidnapping-sexual assault-murderer. It's differ from encounter to post crime, except choice of victims. Through these findings, I can offer crime child missing(especially, sexual kidnapping) investigation outline. First, child missing/kidnapping investigation have to dragnet investigation in the early kidnapping through search cooperation a local resident. Second, police have to short the point of open, and finally it's necessary to come up with measures to increase civil community. Incidentally, I offer crime preventation based on the cases of offender of children under 13. Department of Justice have to include the intelligence and social test, just in case of the offender of children under 13. And I can prevent children's sexual crime for support emotion and training for social adaptation of community. Basically, police investigative capacity need to increase objective and specialized through assistance from outside such as psychologist, sociologist and criminologist. But lots of the data about external missing, child kidnapping investigation emphasize that main agent is the local community include victim family. In conclusion, it's necessary to be mindful of join in local community in these investigation. Furthermore, I think that is in need of study for discrimination between just missing(run away from home, lose a way, etc.) and kidnapping, through the empirical data analysis.
