The reconstruction of dynamic of traffic injuries remains a challenge in forensic pathology and is often based on circumstantial data. Dash Cams are digital video recorders which can be located inside a vehicle and continuously record the view through the windscreen, thus providing objective evidence. Here we present the case of a traffic crash in which a pedestrian was hit by an articulated lorry. The analysis of a video recorded from a Dash Cam retrieved inside the vehicle during the death scene investigation (DSI) was crucial in the reconstruction of the manner of death. Indeed, the death, which was initially assumed to be accidental, was finally deemed as a suicide on the basis of the video recording, which showed an intentional and sudden rush of the victim to the middle of the roadway. Advantages and disadvantages of the use of Dash Cams will be discussed, focusing on the profound differences in the related national and international regulations. Based on the present case, in traffic crashes, the search for Dash Cams during the DSI may be recommended and the video recordings should be analyzed in the setting of a multidisciplinary and multimodal evaluation of the case, for a proper reconstruction of the facts.

交通伤害动态的重建仍然是法医病理学中的一个挑战，并且通常基于间接数据。行车记录仪是一种数字视频录像机，可以安装在车内，通过挡风玻璃连续记录视野，从而提供客观证据。在这里，我们介绍了一起行人被铰接式卡车撞到的交通事故。分析在死亡现场调查 (DSI) 期间从车内取回的行车记录仪录制的视频对于重建死亡方式至关重要。事实上，最初被认为是意外的死亡，最终根据视频记录被认定为自杀，视频显示受害者故意和突然冲到马路中间。将讨论使用行车记录仪的优缺点，重点关注相关国家和国际法规的深刻差异。基于目前的案例，在交通事故中，可能会建议在 DSI 期间搜索行车记录仪，并应在案件的多学科和多模式评估的背景下分析视频记录，以正确重建事实。
