Knowledge in Seeking Crime Scene Evidence of the Inquiry Officers

Abstract

The purpose of this study was to examine the level of knowledge in seeking crime scene evidence of a criminal offense against life and body of the inquiry officers under Provincial Police Region 7 who were on duty from October 2018 to March 2020. The instrument used to collect the data was a questionnaire. The sample consisted of 300 inquiry officers selected by purposive sampling from the population of 664 inquiry officers under Provincial Police Region 7. The collected data were analyzed by using Pearson’s Chi-square and Binary Logistic Regression. The results indicated that most of the inquiry officers had the knowledge and skill in seeking crime scene evidence at a moderate level in which a significant relationship was found between the knowledge in seeking crime scene evidence and years of experience in the investigation, and training in crime scene inspection (time after the recent training). To be specific, the inquiry officers who have more experience in the field of investigation are more knowledgeable in seeking crime scene evidence than those who have less experience. In addition, the factor concerning the time after the recent training can be used to predict the level of knowledge in seeking crime scene evidence according to logistic regression analysis which indicated that the two factors were appropriate and accurate to be used as the indicators of the level of knowledge in seeking crime scene evidence of the inquiry officers at the average of 69.3%.
