Abstract
Currently, there are many crimes. A number of studies on crime scene investigations have been reported. This indicates a significant problem in Thai society, especially crimes involving life and property, such as assault cases, murder cases, robbery or robbery, etc. There must be a method for location analysis in case solving because the crime scene is considered the starting point of an offense. According to criminal statistics from the National Statistical Office, the rates of crime cases related to life, the body, and sex were found to increase from 2011–2022. Each case was complicated and became an unusual staged crime. In these cases, forensic science plays an important role in the investigation of offenders. Therefore, in this study, the effectiveness of the tested fluorescent chemicals, Bluestar and Luminol, for detecting blood stains on single-ply and two-ply towels washed with detergent was investigated. A drop of blood on single-ply and two-ply towels was prepared, and the samples were washed with washing powder and detergent after being left for 2 minutes before cleaning. The single-thread and double-thread towels were cleaned 10 times, each time 1 day apart. After 10 washes, the single-ply and two-ply towels were tested for luminescence reactions with Bluestar and Luminol via photocoagulation. Images of the fluorescence reactions of the Bluestar and Luminol chemicals were then recorded. The results showed that the Bluestar can detect bloodstains on single- and two-ply towels that are washed with washing powder and detergent more than Luminol. Moreover, Bluestar exhibits greater luminescence than Luminol does.
