凶器——枪

打印 被阅读次数

我一向认为在犯罪案件中枪是判断起来最简单直接的凶器。因为一旦开枪,现场就有很多证据可寻。子弹和弹壳,当然是最重要的证据。再来就是火药和枪声。枪的工作原理很简单,扣动扳机,撞针会撞击子弹后部。这个撞击力“点燃”雷管,雷管引起子弹内的火药爆炸,爆炸的力量推动子弹出膛。如果是半自动武器,它的发出装置会推回撞针,扳机也可返回。


有关枪的犯罪,必须找到的证据如下:
1.开了几枪;
2.子弹在哪里?;
3.寻找弹壳掉落的位置;
4.如果枪被留在现场,彻底检查枪支:余留子弹,弹道情况……
5.身体或尸体上的子弹情况。

下面是《Conan》里常见的一种情况:射击残留物

嫌疑人的手上、衣物上可能会发现火药、枪的保养油或是金属残留等的残余物。但是这些残余物是可以经过水洗除去的,而且有些武器是不会发射任何残余物的。当然,枪击伤口附近也会残留射击残留物。
