Forensic scene science is an essential part of the undergraduate teaching of forensic medicine in China, among which the investigation of murder scene is the majority of all, and students should be given to practice teaching on the real murder scene. But due to the restriction by the confidentiality of the case, the protection of students' personal safety and so on, most of the domestic university can't make students go to the scene for an inquest, and instead it with developing case teaching in the classroom generally or inviting the public security police to give lessons to students, which result that the undergraduate of the forensic science are week in crime scene investigation and can't adapt to the front line work of public security after graduation. Based on the above problems, forensic sceneology teaching uses simulated homicide scene to make up for the deficiency in the practical teaching of forensic scene science in order to make students be able to practice what they have learned better.This paper emphatically introduces the design, process and teaching effect evaluation of simulated homicide case.
