The task of forensic investigation is perhaps akin to solving a picture
puzzle. Initially, there are perhaps hundreds, or even thousands, of
seemingly disjointed pieces piled in a heap. When examined individually and
carefully, each piece may not provide much useful information. Methodically,
the various pieces are sorted and patiently fitted together according to a
logical connection. Slowly, an overall picture emerges in your mind. When a
significant portion of the puzzle has been solved, it then is easier for you
to see where the remaining pieces fit.
翻译成中文的参考解答如下
法医调查的任务可能类似于解决一个拼图游戏。
最初，可能有数百甚至数千个看似杂乱无章堆成一堆的拼片。
个别仔细地检查时，每片可能无法提供太多有用的资讯。
根据逻辑的连接，有条不紊地将各式各样的拼片分类并耐心地组装在一起。
你的脑海里慢慢地浮现一个整体的画面。
当拼图的很大一部分已经解决后，你就更容易看到剩余的拼片适合哪里了。
