When a bullet strikes an interposed object before entering a body, the bullet may fragment, or particles from the interposed object may be accelerated. Such secondary missiles may cause multiple entrance wounds if a body is located in line with their flight path. In the unusual case reported here, a silencer acted as an interposed object. The bullet disintegrated completely after impact with the central part of the silencer baffles, which were misaligned. Some bullet fragments were retained inside the silencer, and some exited as a collection of missiles, comparable to shotgun pellets. From a distance of several meters, the fragments wounded the victim at seven different anatomic sites. Use of a silencer should be considered when bullet fragments are recovered from a scene or victim but no other appropriate interposed object is found.
当子弹在进入人体之前击中一个插入物体时，子弹可能会破碎，或者插入物体的颗粒可能会被加速。如果人体位于这些二次投射物的飞行路径上，它们可能会造成多个入口伤口。在本文报道的这一罕见案例中，一个消音器充当了插入物体。子弹与消音器挡板的中心部分碰撞后完全解体，挡板位置不对准。一些子弹碎片留在了消音器内部，一些则作为一系列投射物射出，类似于霰弹枪的弹丸。在几米外，这些碎片在七个不同的解剖部位致受害者受伤。当从现场或受害者身上发现子弹碎片但未找到其他合适的插入物体时，应考虑到使用了消音器。
