The susceptibility for recreational shooters to transfer gunshot residue (GSR) to both the interior and exterior of a vehicle is investigated. A comprehensive sampling protocol was used to assess the most likely areas of GSR transfer from recreational shooter contact, such as the steering wheel and the area, the firearms were stored (the trunk). Up to 315 characteristic GSR, particles were found in several locations throughout the interior of a vehicle. As many as 876 characteristic particles were found throughout a single vehicle. The data indicate that vehicles frequently occupied by firearms users are a potential source for inadvertent transfer of GSR to persons unrelated to firearm activity. In criminal cases where vehicles have been used, such transfer processes for GSR need to be considered within the context of any case interpretation. The implications for subsequent contamination and transfer processes from such vehicles require further investigation.
本文研究了休闲射击者将枪击残留物（GSR）转移到车辆内部和外部的可能性。采用了全面的采样方案，以评估休闲射击者接触后GSR最可能转移的区域，如方向盘以及枪支存放区域（后备箱）。在车辆内部的多个位置发现了多达315个特征性GSR颗粒。在一辆车内总共发现了多达876个特征颗粒。数据表明，经常有枪支使用者乘坐的车辆是GSR意外转移到与枪支活动无关人员身上的潜在来源。在涉及车辆使用的刑事案件中，在任何案件解读的背景下都需要考虑这种GSR转移过程。此类车辆后续污染和转移过程的影响需要进一步调查。
