Abstract

In the investigation process, identifying spots that are suspected to be blood is very important to support the investigation. Blood identification results can be used as a guide to determine the identity of the victim, perpetrator and even the identity of the missing person. Therefore, the blood group identification method used is the elution-absorption test. This test is used to examine evidence in the form of plastic bags, plumbing keys, machetes and their sheaths in cases with different victims. The results of the examination showed that the evidence in the form of plastic bags and plumbing keys had blood type A and the machete and its scabbard had blood type O. The results obtained were in accordance with the victim's blood type.

Abstract

The hyoid bone, a single bone structure in the human neck, has significant potential in forensic identification, particularly for sex determination. This study aims to evaluate the effectiveness of anthropometric measurements and morphological analysis of the hyoid bone across different populations. Using the PRISMA protocol and databases such as Publish or Perish, Science Direct, and Google Scholar, 130 initial studies were identified, with 10 relevant articles selected for detailed analysis. The results reveal significant differences in the dimensions of the hyoid bone, such as length and width, between males and females in various populations. Morphometric analysis demonstrated a 73% accuracy rate in sex identification based on specific characteristics. Other studies utilizing CT-scan techniques reported high accuracy in sex differentiation, with an area under the ROC curve reaching 81.8%. This research also highlights variations in hyoid bone dimensions influenced by population characteristics, analytical methods, and measurement techniques. For instance, the average size of the hyoid bone in males tends to be larger than in females, with statistically significant differences across studies. These findings emphasize the importance of considering population-specific factors in forensic data interpretation. The study concludes that the hyoid bone is a reliable tool for sex determination, especially when methods involve morphometric measurements and CT-scan techniques. Collaboration among forensic experts, radiologists, and anthropologists is recommended to enhance the accuracy and validity of identification outcomes. A systematic approach to using the hyoid bone has the potential to strengthen modern forensic practices with robust scientific foundations.

Abstract

In forensic science, information regarding identity and time of death is crucial in the legal investigation process. Traditionally, investigators determine the time of death by studying physical, chemical, histological, biochemical, and enzymatic changes that occur in a corpse. However, results obtained through these methods are only relevant within 72 hours after death. One method that can be used for a longer time frame is the observation of insects on the corpse. This study aims to observe the pattern of insect arrival on rabbit carcasses (Oryctolagus cuniculus) with different causes of death. The treatments involved complete and incomplete blood drainage, with the carcasses placed indoors under two conditions: slaughtered and lethally anesthetized. Insect observations were conducted in the morning, noon, and afternoon. The insects that arrived were then grouped according to the decomposition stages. The results showed that insects arriving during the early death to bloating stages belonged to the order Diptera (families Muscidae, Calliphoridae, Culicidae, and Sarcophagidae) and the order Hymenoptera. Specific insects that appeared during the decay stage were from the order Diptera (families Fannidae, Drosophilidae, and Asilidae). In the post-decay stage, the insects observed were from the order Diptera (families Muscidae, Calliphoridae, and Culicidae) and the order Hymenoptera.
