A 29-year-old man was involved in a motor vehicle accident as a driver in May 2021. According to the available history, his car overturned and hit a wall. Death was due to head injury. Diffuse brain injury was present. A small piece of glass penetrated the left occipital bone of the skull. What was remarkable was that this wound mimicked a projectile injury. Were it not for the small fragment of glass lodged within the central aspect of the bony wound defect, this wound could have been construed as that of a projectile injury.A small shard of glass penetrated the left occipital aspect of the skull of the victim. This bony wound defect was located approximately 6 cm posterior-and-lateral from the greater wing of the left sphenoid bone. This bony wound defect showed inward beveling of bone. The tabula externa defect measured approximately 1 cm in diameter. The tabula interna defect measured approximately ILLUSTRATED FORENSIC PATHOLOGY e10 www.amjforensicmedicine.com

The refractive index measurement is a widely used investigation method of glass microtraces in forensic laboratories. The advantage of the method, in addition to its cost efficiency and repeatability, is that it is suitable for examining small fragments. In the present study, a real case was simulated, and fragments smaller than 250 micrometers obtained from five pieces of clothing, after breaking a pane of float glass, were investigated. In addition to the known (control) sample, altogether 25 bulk and 83 recovered surface fragments were also examined. In the first step, only one measurement was performed for each fragment to simulate the investigation of small fragments and test their measurability without crushing. All the bulk fragments met with the matching criterion K min ≤ Q ≤ K max , in which K min and K max are the minimum/maximum value of the measured refractive indices of the known sample, while Q is the measured (mean) value of the questioned fragment. However, the matching ratio was only approximately 60% for the surface fragments according to the one-edge measurements.After crushing, the false exclusion rate was significantly reduced, and 79 of the 83 recovered surface fragments met with the matching criterion. As a result of crushing, not only the probability of matching, but also the edge count values improved significantly. Although the refractive index is only one property examined in the totality of glass analysis, the results of the present work can significantly contribute to the determination of the origin of small glass particles in real forensic cases.

“…The transfer of glass from the surface of a card bound box to the cloth of the person carrying the box has been investigated (657). The distribution of glass fragments on the ground near a vehicle when the windshield has been broken has been examined (658). It has been found that glass fragment shapes cannot be used to distinguish glass acquired by backward fragmentation from a broken window or glass acquired through contact with a broken window (659).…”
