SPECIFIC TRAUMATIC INJURIES ESTABLISHED ON THE BODY OF A MOTORCYCLIST ASSOCIATED WITH A TRAFFIC ACCIDENT

Introduction: Traffic accidents are a common cause of traumatic injuries today and are the cause of a great number of deaths. The information, gathered from the site of the accident, the forensic autopsy and the toxicological analysis of blood and urine samples taken from the deceased, reveals the sequence of events leading to the incident, the type of vehicle involved in the crash, the place of the occupants of the vehicle, the cause of the death and the mechanism of occurring of the injuries. Materials and methods: forensic autopsy of the body; chemical analyses of blood and urine. Case presentation: We present a case of a 30-year-old male motorcyclist who died in a traffic accident, as he was hit and run over by a cargo truck. The body of the deceased was examined in the Department of Forensic medicine and deontology, Sofia. Multiple traumatic injuries were identified, with specific findings on the chest and the abdomen – excoriations with specific shape corresponding to a specific detail (an identification number) of the tire of the motor vehicle. Discussion: Traumatic injuries on the chest and abdomen were due to contact with a motor vehicle tire element, expressed as a positive-negative imprint. This statement is firmly proven based on the specific injury located on the thorax and abdomen with visualization of the serial number of the tire. Conclusion: Every detail, traumatic injuries and their comparison are essential for the correct interpretation of a traffic accident to recreate the events that led to the incident and its outcomes, i.e. building a situational image of a traffic accident

BIO-TRACE ANALYSIS OF A BITE MARK SCAR LEFT ON THE HAND OF A PERPETRATOR OF A CRIME – A FORENSIC CASE REPORT

Introduction: We present a case of a homicide of a woman that was manually strangulated after she was sexually abused. On the right hand of the suspect specific scars were observed that could be dated around a month before our examination. In addition we were given gypsum casts of the deceased’s upper and lower jaws, as well as all the autopsy findings. Materials and methods: Examination of the suspect, analysis of the autopsy findings and the gypsum casts from the upper and lower jaws of the deceased, photo-superimposition, analysis of the results. Results: In this case, the obtained results showed the stable characteristics after the static and dynamic impact on perceptive surface (the hand of the perpetrator). These characteristics of the scars perfectly matched the specific features of the gypsum casts from the upper and lower jaw of the deceased. The study was performed by photo-superimposition and bio-trace analysis. Conclusion: Such types of forensic analysis are extremely important and informative in investigating criminal offenses, especially in cases where there is no other objective evidence (material evidence, testimony, available DNA research material, etc.) to identify the perpetrator of the crime
