Abstract

Crime Scene Investigation process is a step in the legal process for finding evidence to identify the offender. From a case study of Police Forensic Science Center 4, Khon Kaen, Thailand, an inquiry official used to report details of crime scene to Crime Scene Notification (CSN) center by telephone when a crime happened. After the service officer received notice case and wrote it on paper which may cause data loss and may take time to inquire more information. The process causes delayed data and unorganized storage, as a consequence; smartphones or tablets were utilized to solve these problems. This research proposes a development of a notification system for the crime scene investigation on android devices and web application. This system facilitates form-filling, file-recording, saving multimedia files, geographical search, navigation, and push notification message. The system allows the operation of the staff to be more convenient and the data to be orderly stored. The result shows that an average usability of web application was 76.65 while mobile application was 76.25. The result of the satisfaction evaluation of both systems was at a good level. Therefore, the developed system can be applied. It's an added way to be notified anytime and anywhere. As a result, the overall performance is more effective.
