Firearm projectiles striking intermediate targets have the potential to create secondary projectiles, which can produce identifiable patterns of injury. We present a case in which a father, manipulating a handgun, was demonstrating how the firing pin worked to his adolescent son. He placed a pen inside the barrel of the gun for demonstration but did not recognize that a bullet was loaded into the firing chamber. The weapon was discharged causing fatal injury to the son. The pen, as an intermediate target, created identifiable injuries on the decedent, which were consistent with typical patterns of injury seen with secondary projectiles including a discrepant number of skin defects to number of counted projectiles and pseudo-stippling. Recognition of these identifiable patterns of injury in intermediate target involved gunshot wound cases can help support other autopsy findings and scene investigation.
当射弹击中中间目标时，有可能会产生次级射弹，从而导致可识别的损伤模式。我们呈现了一个案例，一位父亲在向他十几岁的儿子演示击针的工作原理时，手里拿着一把手枪，将一支笔放在枪管内进行演示，但他没有意识到枪膛内装有子弹。结果枪走火了，导致儿子致命受伤。笔作为中间目标，在死者身上造成了可识别的损伤，这些损伤与次级射弹造成的典型损伤模式一致，包括皮肤缺陷数量与计数射弹数量之间的差异以及伪星状擦伤。在涉及中间目标的涉枪伤害案件中，识别这些可识别的损伤模式有助于支持其他尸检发现和现场调查。
