A road-rage altercation occurred between two vehicle drivers. The driver of vehicle 1 stopped and allegedly fired two shots from within his vehicle over the heads of the driver and passenger of vehicle 2 when they were out of their vehicle. The driver of vehicle 2, an off-duty police officer, fired his .45 calibre pistol at the driver of vehicle 1. The bullet went through the windshield and lodged in the instrument panel. Eight gunshot residue (GSR) samples were taken from the interior of vehicle 1 and analysed by automated scanning electron microscopy/energy dispersive x-ray spectroscopy. The results show for vehicle 1 that a firearm discharged with its breach or cylinder gap within the vehicle was unlikely to have occurred and the .45 calibre bullet which impacted five surfaces of vehicle 1 was accompanied by GSR throughout its travel. A recreational shooter is shown in this study to transfer GSR to the seat of his car. The driver of vehicle 1 visited a recreational gun range prior to the altercation, which would explain the significant GSR contamination of the driver's seat of his vehicle.
两名车辆驾驶员之间发生了路怒冲突。1号车驾驶员停车，据称在2号车的驾驶员和乘客下车后，从其车内朝他们头顶上方开了两枪。2号车驾驶员是一名休班警察，他用自己的.45口径手枪向1号车驾驶员开枪。子弹穿过挡风玻璃，嵌在了仪表盘里。从1号车内部采集了8份枪击残留物（GSR）样本，并通过自动扫描电子显微镜/能量色散X射线光谱法进行分析。结果显示，对于1号车来说，不太可能发生在车内从枪膛或气缸间隙开枪的情况，撞击1号车五个表面的.45口径子弹在整个行程中都伴有枪击残留物。本研究表明，一名休闲射击者会将枪击残留物转移到他的汽车座椅上。1号车驾驶员在冲突发生前去过一个休闲射击场，这就解释了其车辆驾驶员座椅上存在大量枪击残留物污染的原因。
