大部分罪犯都会小心行事以避免被发现。他们可能会戴手套以防留下指纹,戴面罩挡住他们的脸,或者戴帽子以免头发脱落留在现场。即便如此,他们穿的鞋,使用的工具,逃逸时驾驶的交通工具都会在犯罪现场留下明显的痕迹。这些痕迹可以作为线索,有时法证侦探们还会以此作为有力的证据。 Most criminals act cautiously to avoid being discovered. They may wear gloves to prevent fingerprints, wear masks to block their faces, or wear caps to prevent hair loss from leaving the scene. Even so, the shoes they wear, the tools they use, and the means of transport they are driving while fleeing, leave clear marks on the scene of the crime. These traces can be used as clues, and sometimes forensic detectives will use this as a strong evidence.
