The final part of the paper provides some proposals for the ways to implement the requirements by defining skills improvement opportunities for investigators and investigators of operational cases. It also describes methods of office employees’ skills improvement, crime prevention and IT sphere.展开更多

The use of citizen volunteers, citizen awareness campaigns, community-driven research, and programs that facilitate effective police-community relations can aid the investigator in collecting testimony that might otherwise go unreported. Specific examples of how cases have been cleared due to the beneficial inclusion of citizen satisfaction research, crime prevention resources, and volunteer personnel demonstrate how community, crime prevention, and investigation of criminal behavior can be interlinked. The theme of this paper rests on the notion that the community＇s sense of collective efficacy, crime prevention efforts, and criminal investigation processes are not mutually exclusive, but instead should be considered as related aspects of the crime-fighting spectrum.展开更多

Data were collected from all related agencies. The results of this research have showed that executive process of forensic science is used to investigate the crime in three southern border provinces that can be divided the operations into three main issues as following： crime scene examination, evidence testing, autopsy in case of crime scene, and factors which affect forensic work for using in criminal investigation in three southern border provinces of police practitioners. They should have the knowledge about forensic science, commitment, bravery, and cunning work.展开更多
