우리나라에서도 특징적 동기가 없거나 확인이 어려운 무동기 범죄가 증가추세에 있다. 이는 계층의 경제적 양극화, 신속주의, 쾌락주의, 폭력적 문화의 팽배 등 이른바 사회정신병리적 현상에 기인한 것으로 판단된다. 무동기 범죄의 해결을 위해서 기존의 일반적 수사기법의 적용으로는 많은 한계가 있다. 경찰은 무동기 흉악범죄사건을 조기에 해결하기 위해서는 과학적인 수사기법의 개발과 수사경찰의 전문화 등 다양한 노력이 필요한 시점이다. 무동기 흉악범죄에 대한 효과적인 경찰대응을 위한 방안을 제시하면, 1) 유전자정보의 활용, 2) 프로파일링 기법의 과학화와 D/B화, 3) 과학적 감식체제의 강화, 4) 최신 첨단 과학수사기법의 개발과 도입과 더불어 검경간 및 형사사법기관간의 보유자료의 공유와 상호협조체제의 구축 등도 무동기 흉악범죄를 조기에 검거하고 차단하는 경찰대응의 효과적인 방안이라고 판단한다.

The second, profiling technique can be a efficient countermeasure to motiveless crimes. a given circumstance should be prepared to develop profiling that is a psychological method at primary level. The third, to collect correct information for identification of a person accidentally killed, a joint on-the-spot attendance system by spot identification personnel and legal medicine specialist shall be institutionalized.
